When foreign investors enter into a joint venture with a Thai partner, they often arrive with a globally standardized Joint Venture Agreement (JVA) prepared by offshore counsel. On paper, it looks polished, comprehensive, and commercially sophisticated.The problem is that a well-drafted international template does not automatically work under Thai corporate law.In practice, many cross-border JV documents are negotiated around commercial expectations developed in other jurisdictions, while the actual company is a Thai private limited company governed by the Thai Civil and Commercial Code (CCC), its registered Articles of Association (AOA), and the corporate procedures recognized by the Ministry of Commerce. If the deal documents are not properly localized, the parties may discover too late that their contractual bargain is not fully effective at the company level.Here are three common areas where global JV templates often run into trouble in Thailand.1. Reserved Matters in the JVA Do Not Automatically Bind the CompanyIn many joint ventures, one party holds a majority stake while the other holds a significant minority position. To protect that minority position, investors often negotiate a list of “Reserved Matters” requiring their consent.These typically include matters such as approval of annual budgets, incurring material indebtedness, appointing senior management, changing the business plan, or entering into major transactions.The difficulty under Thai law is that a JVA is, fundamentally, a private contract between the shareholders. By contrast, the validity of corporate action by a Thai private limited company is determined by the CCC, the company’s AOA, and properly passed board or shareholder resolutions.That means reserved matters written only into the JVA are not necessarily self-executing under Thai corporate law. If the relevant veto mechanics are not properly reflected in the company's constitutional and governance documents, for example through appropriate quorum rules, voting thresholds, board composition, director appointment rights, or other enforceable corporate mechanisms, the majority shareholder may still be able to pass resolutions validly at the company level.In that situation, the minority investor may still have a contractual claim for breach of the JVA, but that is very different from preventing the corporate action from taking effect in the first place.The Practical Lesson: in a Thai JV, reserved matters should not be left as purely contractual protections. They need to be translated, where legally possible, into workable corporate mechanics under Thai law.2. Capital Call and Dilution Clauses Cannot Ignore Thai Pre-Emptive RightsA second common issue arises when international JV templates assume that, if one shareholder refuses to fund the business, the other can simply inject more money and automatically dilute the defaulting shareholder.That assumption needs to be treated with caution in Thailand.Under Thai corporate law, a capital increase by a private limited company is subject to formal corporate procedures, and new shares must generally be offered to existing shareholders in proportion to their current shareholdings before they can be allocated elsewhere. As a result, a dilution mechanism that appears commercially straightforward in an offshore template may not be directly enforceable in the way the parties expect.This does not mean that dilution consequences can never be structured in a Thai JV. They often can. But they must be built around Thai corporate procedures, documentary requirements, notice mechanics, and properly coordinated default provisions. A clause that assumes dilution will happen automatically, without following the required company law process, may prove ineffective or difficult to implement in practice.The Practical Lesson: Thai-law capital call provisions need careful structuring. Commercial pressure mechanisms may be agreed, but the route to dilution must still respect the mandatory corporate framework.3. Debt-to-Equity Solutions Are More Restricted Than Many Templates AssumeWhen a JV is under financial pressure, foreign investors often propose what seems like an efficient solution: convert outstanding shareholder loans into equity.In Thailand, that approach is not always straightforward for a private limited company.Global templates sometimes assume that unpaid subscription amounts can simply be set off against debts owed by the company to the subscribing shareholder. Under Thai law, however, that kind of classic debt-to-equity conversion by way of set-off is heavily restricted and should not be assumed to be available as a matter of course.Even where the commercial objective is sensible, the legal implementation needs to be analyzed carefully under Thai company law, accounting treatment, corporate approvals, and any applicable regulatory conditions.This becomes even more important where the company operates under a promoted or licensed regime. For example, where a business is operating under conditions imposed by the Board of Investment (BOI) or under a foreign business licensing framework, the company's financing structure may need to remain consistent with applicable capitalization requirements or license conditions. Those constraints are not uniform in every case, but they can be highly relevant and should be reviewed before the parties rely on repeated shareholder lending as a substitute for proper recapitalization.The Practical Lesson: in Thailand, financial rescue tools that look simple in a global template often require restructuring before they work lawfully and effectively on the ground.The Bottom LineA strong global JVA is a useful starting point, but it is not a substitute for Thai-law implementation.In a Thai joint venture, the real question is not only what the parties have agreed commercially. It is whether those rights and protections can actually operate through the legal mechanics of a Thai private limited company.If the answer is no, the parties may end up with a beautifully drafted contract that offers remedies only after the damage has already been done.Before signing any cross-border JV in Thailand, investors should ensure that the JVA, the AOA, the shareholder structure, the board mechanics, the funding provisions, and the regulatory position all work together as a single legal architecture.Because in Thailand, localization is not just a drafting exercise. It is what makes the deal actually function.Authors:Wethaka Saenprom │ Senior Associate │ [email protected] Pitchayathammawong │ Associate │ [email protected] Suwanchaluay │ Associate │ [email protected] Khingmontri │ Associate │ [email protected]

As the world grapples with geopolitical instability and shifting global trade dynamics – including the recent tensions along the Thai-Cambodian border and U.S. tax pressure – foreign investors may naturally feel cautious. However, a deeper look at Thailand’s economic fundamentals, legal framework, and proactive government policies reveals a resilient and attractive investment landscape. Strategic Location in ASEAN’s Economic Heart Thailand remains at the center of mainland Southeast Asia, serving as a natural hub for trade, logistics, and regional operations. The country is uniquely positioned to access over 660 million consumers across ASEAN, and continues to play a central role in regional supply chains, particularly in automotive, electronics, agritech, and medical industries. Even in the face of regional instability, Thailand’s infrastructure, cross-border logistics, and customs facilitation remain largely unaffected. The government has taken measured steps to insulate commercial zones and economic activities from political or military disruptions, maintaining a functional and secure environment for investors. Resilient Economy with Diversified Strengths Thailand boasts one of the most diversified economies in Southeast Asia. From advanced manufacturing and digital services to agriculture and tourism, the country is not overly dependent on any single sector or trading partner. This diversification has allowed the economy to absorb external shocks better than many of its neighbors. Additionally, Thailand has maintained a relatively low inflation rate and a stable currency, thanks to prudent fiscal and monetary policies. Despite global volatility, the country continues to register steady GDP growth, with significant inflows into green energy, logistics, biotech, and digital sectors. Robust Legal and Regulatory Environment Thailand’s legal infrastructure governing foreign direct investment (“FDI”) is mature, transparent, and business-friendly. Foreign investors are supported and protected under key laws such as the Investment Promotion Act (known as “BOI”) and Eastern Special Development Zone Act (known as “EEC”). Dispute resolution mechanisms, both judicial and arbitral, are well developed. The BOI and EEC continues to offer generous incentives for eligible businesses.   Sample Incentives Corporate income tax exemptions for up to 13 years; 100% foreign ownership in promoted sectors; Import duty exemptions on machinery and raw materials; and Work permit and visa facilitation for foreign staff. Even during geopolitical tensions, BOI and EEC remains fully operational and responsive. In fact, the Thai government has continually promoted digital infrastructure, clean energy, medical innovation, and EV-related investment by offering additional incentives to investors willing to participate in the nation’s strategic transformation. Political Neutrality in Trade Tensions While U.S. policies under Trump may reflect a trend toward economic nationalism, Thailand remains a politically neutral and open economy. It is a signatory to key international treaties such as the Regional Comprehensive Economic Partnership (RCEP), and maintains free trade agreements with China, Japan, Australia, India, and the EU (under negotiation). This neutral positioning allows investors in Thailand to maintain access to both Western and Eastern markets without being directly exposed to retaliatory trade barriers or tariffs.   Conclusion In uncertain times, clarity and control become vital. Thailand offers investors both: a clear legal pathway for foreign ownership, and a stable, investor-oriented environment to grow their regional footprint. While conflicts and shifting global politics may dominate the headlines, seasoned investors know that long-term success lies in resilience, diversification, and institutional support – all of which Thailand continues to deliver. If you're considering your next strategic move in Asia, Thailand deserves a closer look.

Despite recent political unrest and ongoing border conflicts, Thailand has continued to attract foreign investors across several business sectors in recent years. While the overall concept of company incorporation may be similar to that of other countries, the specific criteria and process for establishing a company in Thailand differ in important ways. In this article, we address the most frequently asked questions from our clients about incorporating a company in Thailand. Our aim is to provide clear, practical explanations to help you begin the incorporation process with confidence. Question 1. Does Thai law allow a company to be 100% foreign owned? The Thai Civil and Commercial Code (the “CCC”), which is the law governing and regulating a limited company, does not prohibit foreigners from holding 100% of shares in a company. Therefore, a company can be legally established and exist with all its shares being held by foreigners. However, if foreigners own 51% or more of a company’s aggregate shares, the company will be regarded as a foreign company. It will then be subject to certain restrictions on business commencement—such as limitations on operating specific types of businesses—under the Foreign Business Act B.E. 2542 (the “FBA”). The details of these restrictions will be further elaborated. Question 2. What is the minimum number of shareholders and any other requirements? Currently, the CCC requires a limited company to have at least 2 shareholders at all time. Shareholders can be individuals and/or juristic persons. Noted that the company promoters, who play the key role in forming and registering the company, must be individuals and must subscribe at least 1 share when incorporate the company. Due to this requirement, these 2 individual promoters will be the initial shareholders of the company. Question 3. Is there any requirement on the minimum number or nationality of director? A company must have at least 1 director. Apart from appointing directors, the company must also register the authorized signatory directors and the signing conditions to bind the company. There are no restrictions or requirements on the qualifications or nationality of the director. However, in case the company is 100% Thai-owned but a foreigner is named the sole or joint authorized director, the company will be required to submit to the Department of Business Development (the “DBD”) the letter or certificate issued by the bank to confirm that all Thai shareholders in the company have a sufficient account balance to subscribe for the shares. The requirement that Thai shareholders must demonstrate financial capability by providing sufficient account balances exists to ensure that they are truly able to subscribe to the company's shares, rather than serving as nominees for foreign investors. This measure helps maintain genuine local ownership and prevents circumvention of foreign investment regulations, thereby supporting transparency and the integrity of Thailand’s business environment. Question 4. What is the minimum registered capital for a Thai company? There is no minimum registered capital required by the law and the company can be incorporated with the registered capital it deems appropriate for commencing its business. If the registered capital exceeds 5 million Thai Baht, the company will be required to submit, together with the application for incorporation to the DBD, the banking evidence which proves the remittance of share payment into any of the directors’ bank account. If all directors are foreigner and unable to open the bank account in Thailand for receiving the share payment, the DBD permits the required bank evidence to be submitted within 15 days after the DBD registrar approved the incorporation. Failure to comply with this timeframe, the DBD is empowered to revoke the incorporation. Question 5. What are the Articles of Association and how are they important? Articles of Association (the “AOA”) are the by-laws of the company. Apart from the provisions of the CCC, directors and shareholders are obligated to manage and control the company in accordance with the AOA. Basically, the AOA will specify certain basic rules about the company, such as, classes and groups of shares, number of directors, limitation of the authority of directors, how to summon shareholders’ or the board of directors’ meetings, how board of directors’ and shareholders’ resolutions can be passed, etc. The Articles of Association of the company can be established in one of the following ways: • Adoption of the provisions of corporate law under the CCC in the absence of any customized articles. • Standard template of AOA as provided by the DBD: The company adopts a government-issued template, which contains standard provisions approved by the authorities and is designed for general use. • Company’s own version of AOA: The company drafts its own set of rules, tailored to its specific needs and preferences, allowing for customization of governance and internal procedures. If the company decides to draft its own AOA, the DBD registrar will review to ensure that no articles are in contradiction to the provisions of the CCC. As such, this option will result in the longer registration period compared with the adoption of the CCC or standard template of the DBD as the company’s AOA. However, in the case of a joint venture company, certain clauses agreed upon by the parties to the joint venture agreement should be incorporated into the AOA. For example, provisions regarding meeting quorum, voting rights, and dividend entitlements should be included. Including these clauses in the AOA helps guarantee that the terms of the joint venture agreement are properly implemented and observed by all parties and the company itself. Question 6. Is it necessary for the company to have an office in Thailand? Yes, the CCC requires the company to register the address of its premises when incorporating the company and this premises must locate in Thailand. In addition to the address, an 11-digit house registration number must also be provided in the application. This house registration number can be found in the document called “Thai House Book” or in Thai as “Tabien Baan” which is an administrative document issued by the local municipality to the house owner or the landlord. In case the company leases space in the office building, the house registration number must be requested from the landlord or lessor. Question 7. Is it necessary to appoint an auditor by the time of the company incorporation? The CCC does not require the company to appoint its auditor by the time of its establishment. Therefore, the appointment of auditor and the determination of the remuneration can be resolved by the shareholders’ meeting later after the company incorporation. Question 8. What is the fiscal year for a company in Thailand? The fiscal year refers to the 12-month period used by a company for accounting and tax purposes. In Thailand, the company can choose its own fiscal year (e.g., April 1 to March 31 or July 1 to June 30) as long as it is clearly stated in its Articles of Association, which does not necessarily have to follow the calendar year (January 1 to December 31). Many companies prefer their fiscal year to start and end on the same date as their parent company. This alignment simplifies the process of combining financial statements and ensures consistency in reporting across the corporate group, making financial consolidation more efficient. Question 9. How long does it take to register a company in Thailand? The registration process typically takes about 3–5 working days after the complete application and supporting documents are submitted to the DBD registrar. The DBD registrar may require additional time to review the application, depending on the volume of pending cases and the complexity of the submission. For example, if the Articles of Association of the company are complex and contain many special clauses, this may take additional time for the registrar to review and approve the application. In some instances, the registrar may request amendments to the content of the Articles of Association to bring it in line with the provisions of the CCC. For instance, a clause that grants unusual voting rights to certain shareholders might need to be revised to comply with standard company law requirements. Question 10. Can a company immediately commence business in Thailand after being registered? Once the company is registered with the DBD, it can commence business within the scope of objectives it registered with the DBD. However, if 51% or more of total shares in the company is held by foreigner, its business operation will be subject to the restriction under the FBA. By virtue of the FBA, a foreign company is prohibited from carrying out certain types of businesses in Thailand unless they obtained a Foreign Business License (FBL) or Foreign Business Certificate (FBC) issued in accordance with the approval from the Board of Investment of Thailand (BOI), the Industrial Estate Authority of Thailand (IEAT), or in compliance with any treaty to which Thailand is a party. There are 3 Lists of prohibited businesses for foreigner as annexed to the FBA as follows: List 1: Businesses that are strictly prohibited for foreigners by special reason, such as land trading, rice farming, livestock farming, radio broadcasting station, extraction of Thai medicinal herbs, making or casting Buddha Images and monk alms-bowls, etc. List 2: Businesses related to national safety or security or having impacts on arts, culture, traditions, customs and folklore handicrafts or natural resources and the environment, such as production of wood carvings, domestic transportation, salt farming, mining, etc. List 3: Businesses that Thais are not ready to compete with foreigners, such as engineering services, architectural services, legal and/or accounting services, other services, construction, retail sale, wholesale, etc. For legal assistance, please contact: [email protected] Mr. Krittin Pollagan Partner 

Thailand continues to be one of the key destinations for foreign investment in Southeast Asia,particularly in manufacturing, technology, infrastructure, digital services and other high-valueindustries. However, foreign investors considering an investment in Thailand are often faced with the same question: “Can a foreign investor own 100% of the shares?”Under the Foreign Business Act B.E. 2542 (1999) (the “FBA”), there is no standard rule thatforeign investors may only hold 49% of the shares in every Thai company. At the same time,100% foreign ownership is not available for every business. The key consideration is the actualbusiness activity to be carried on in Thailand and whether such activity is restricted under the FBA or other applicable laws.Accordingly, proper legal structuring should begin with the business itself rather than simplydetermining the percentage of foreign and Thai shareholding.This article highlights the key legal and practical considerations that foreign investors should be aware of when structuring an investment in Thailand, including Foreign Business Licence (“FBL”), Board of Investment (“BOI”), Eastern Economic Corridor (“EEC”), Industrial Estate Authority of Thailand (“IEAT”), and joint venture structures.Why Legal Structuring Is ImportantBefore establishing a company in Thailand, foreign investors should first identify precisely what the proposed company will do and, in particular, which activities will generate revenue.The analysis should not be based only on the general description of the project. A single project may involve several different activities, and each activity may be subject to different legal requirements. For example, a foreign-invested company may be permitted to carry on amanufacturing activity without an FBL, while its separate service, retail or wholesale activities may still require further consideration under the FBA.Similarly, obtaining BOI promotion for one activity does not necessarily permit the company to carry on other non-promoted activities without considering whether separate permission is required.For this reason, foreign investment structuring should generally consider the following questions at an early stage.What exactly will generate revenue?Is each activity restricted?Does an FBL express exception apply?Can BOI, IEAT or EEC support the project?If permission is needed, FBC or FBL?If a JV is chosen, is it genuine?How the Foreign Business Act AppliesUnder the FBA, a foreign investor must first determine whether the proposed business falls within any of the restricted business categories.The FBA contains three lists of restricted businesses.List 1 covers businesses reserved for Thai nationals. Foreigners are not permitted to carry onthese activities under the FBA.List 2 covers businesses relating to national safety or security, arts, culture, traditions,customs,handicrafts, natural resources and the environment.List 3 covers businesses in which Thai nationals are considered not yet ready to compete withforeigners.In practice, the foreign investors may apply FBL for those businesses falling under List 3.On the other hand, activities that do not fall within the restricted lists generally do not requirepermission under the FBA. These may include manufacturing activities, export businesses and other activities falling outside the restricted categories, subject to the particular nature of the business and other applicable laws.When an FBL May Not Be RequiredBefore proceeding with an FBL application, foreign investors should consider whether theproposed business is outside the restricted lists or falls within an applicable exemption orexception.Examples may include:Manufacturing and export businessesRetail: THB 100m total capital, or THB 20m per storeWholesale: THB 100m per storeNon-income-generating entities (representative/regional offices)Express statutory exceptions (e.g government-contracted services)Where none of the available exceptions apply and an FBL is required, investors should firstidentify the exact restricted activity and may consider pre-consultation with the relevant DBDofficer before proceeding with the application.Identify the business activity preciselyPre-consult with the relevant DBD officeEstablish the appropriate legal entityPrepare and submit the FBL applicationIt is also important to note that an FBL only permits the company to carry on the approvedrestricted business. It does not itself confer land ownership rights or provide the tax and non-tax incentives available under investment promotion regimes.Nominee Shareholding Is Not a Structuring SolutionWhere an activity is restricted, the use of Thai nominee shareholders is NOT a lawful alternative to obtaining the appropriate permission.Section 36 of the FBA addresses conduct involving Thai nationals or juristic persons who assist foreigners in carrying on restricted businesses in circumvention or violation of the FBA. Such conduct may include, among others, holding shares on behalf of a foreigner, appearing as the owner of a business operated for a foreigner, aiding or abetting prohibited conduct, or otherwise participating in an arrangement intended to circumvent the FBA.It is important to distinguish a nominee arrangement from a genuine joint venture. Thai investors may legitimately invest and participate in a business together with foreign investors. The concern arises where the Thai shareholder does not make a genuine investment or does not exercise genuine rights as a shareholder, but merely holds shares on behalf of the foreign investor.In practice, nominee shareholding continues to be an area of close regulatory attention. TheDepartment of Business Development (so-called “DBD”) has identified several measures toprevent and suppress nominee arrangements, including verification of the financial status of Thai investors, monitoring high-risk entities and business groups, cooperation with other government agencies and continued development of relevant laws and regulations.Verify the financial status of Thai investors before juristic person registration.Identify nominee-risk entities and high-risk business groups for closer monitoring.Work together with relevant government agencies.Update laws and regulatory measures relating to nominee arrangements.BOI, EEC and IEATWhere a business is restricted under the FBA, an FBL may not necessarily be the only available structure. Depending on the business activity and location, foreign investors may consider BOI promotion, EEC incentives or IEAT permission.BOI Promotion: Eligible activity → promoted project → foreign ownershippermission → FBC for the promoted scope.EEC: Geographic route across Chachoengsao, Chonburi and Rayong, across five target industry clusters.IEAT: Industrial estate location → IEAT permission → FBC under Section 12, limited tothe permitted scope.Board of InvestmentBOI promotion is one of the principal routes commonly considered by foreign investors where the proposed business falls within an eligible promoted activity.In general, an eligible activity may be approved as a promoted project. The relevant promotion may then provide the foreign ownership basis for the project and support an FBC for the restricted promoted scope.The BOI currently considers investment promotion projects through four Investment Promotion Divisions.Division 1: Agricultural, food, biotechnology and medical industriesDivision 2: Advanced manufacturing industriesDivision 3: Basic and supporting industriesDivision 4: Digital, creative industries and high-value servicesIn addition to the foreign ownership structure, BOI-promoted projects may be entitled to tax and non-tax incentives, depending on the category and conditions of the promotion.Tax Incentives Import duty exemption/reduction on machinery Import duty reduction on raw or essential materials Import duty exemption on R&D materials CIT exemption on net profit & dividends 50% CIT reduction Double deduction on transport/utilities 25% additional deduction, facility costs Import duty exemption, export production materials Non-Tax Incentives Entry permit to study investment opportunities Permit to bring in skilled workers/experts Permit to own land Permit to remit money abroad in foreign currency Eastern Economic CorridorThe EEC covers Chachoengsao, Chonburi and Rayong and has been established as a strategic investment area for targeted industries.Medical and Comprehensive Healthcare Digital Next-Generation Automotive BCG Economy ServicesDepending on the nature of the project, its location and the applicable approval criteria, additional tax and non-tax incentives may be available under the EEC framework.These may include, among others, land ownership rights within Special Economic Promotion Zones, condominium ownership rights and immigration or work-permit facilitation. However, being located within the EEC does not automatically entitle every business to the maximum EEC incentives. The eligibility of the particular project and conditions attached to the relevant approval must still be considered.Industrial Estate Authority of ThailandAn additional route may be available where the company operates within an industrial estate under the IEAT framework. In general, the structure may involve obtaining IEAT permission for the relevant business and subsequently obtaining an FBC under Section 12 of the FBA for the permitted scope.Industrial Estate → IEAT Permission → FBC Under Section 12 One Project May Require More Than One FrameworkA single investment project may involve several regulatory frameworks, including the FBA, BOI, EEC and IEAT regimes, at the same time. Investors should therefore consider each approval separately and understand the specific rights and permissions granted under each framework.Getting the Joint Venture RightWhere the desired structure cannot be achieved through an exemption, FBL, BOI, EEC or IEAT route, foreign investors may consider establishing a genuine joint venture with a Thai partner. However, the Thai partner should be a genuine investor and not merely a shareholder introduced to satisfy a particular ownership percentage.In practice, the substance of the Thai partner's participation is important.A genuine JV partner is not merely a shareholder introduced to satisfy the 51% Thai ownership requirement. A genuine JV partner must demonstrate real economic participation, business contribution and involvement in the management of the company How do we determine whether the Thai partner is genuine? Consider the following five key factors. Own Capital Contribution Real Economic Risk Meaningful Governance Role Participation in Returns Ability to explain the investment Where these elements exist, the parties should then ensure that their commercial relationship is properly reflected in the Joint Venture Agreement (“JVA”).General Terms and Conditions of the JVAThe parties should ensure that the key terms and conditions between the joint venture parties properly reflected in the Joint Venture Agreement, including:Capitalisation: Each party's capital contribution - what, and when. Board: Board sets, appointment and removal rights Quorum: Minimum attendance required for valid board decisions Reserved Matters: Decisions requiring approval from both parties. Funding: Future funding needs - equity, shareholder loans, or dilution Deadlock: Mechanism to resolve disputes - escalation, mediation, or exit. Transfers: Restrictions on when and how shares can be sold or transferred. A genuine JV structure is demonstrated not only by actual participation in the business, but also by a well-structured JVA that reflects the true commercial relationship between the parties.Final ThoughtAs set out above, Thailand offers several legitimate legal pathways, including activities outside the restricted lists, FBLs, BOI promotion, EEC incentives, IEAT permission, and genuine joint ventures, for structuring a company with majority or full foreign ownership, without resorting to nominee arrangements. The right structure depends on the actual business activity, source of revenue, proposed location, and available approvals. Foreign investors should assess these factors at an early stage, rather than defaulting to an assumed 49:51 shareholding split.For further guidance on structuring your investment in Thailand, please contact:Bunnasomboon Chaiparinya (Aaron)Partner and Head of Corporate DepartmentEmail: [email protected]

Understanding Thai labour laws is essential for employers, as these rules help ensure fair, compliant, and well- governed workplaces. Employment-related issues arise regularly, making it important for organizations to stay informed and aligned with legal requirements.This Q&A article brings together some of the most frequently asked questions by employers, providing practical explanations to help organizations navigate both current legal requirements and the upcoming legal changes that could significantly impact workplace policies. Question 1. What should employers know before preparing an employment agreement in Thailand?Thai law does not require an employment agreement to be in writing. An employment contract may be oral or written, and it will still be legally valid as long as there is a mutual agreement between employer and employee. However, having a written employment agreement is strongly recommended, as it clearly sets out the terms and conditions of employment (e.g., position, salary, benefits, termination clause) and serves as crucial evidence in case of a labour dispute before the Labour Court. Question 2. What is the difference between probationary employees and full-time employees under Thai law, and does this apply to foreign employees?Under Thai law, there is no legal distinction between “probationary” and “permanent” employees. Both are equally protected under the Labour Protection Act B.E. 2541 (1998) (“LPA”), meaning that probationary employees are entitled to the same statutory rights as permanent employees — such as minimum wage, working hours, overtime pay, and leave entitlements.These protections apply equally to foreign employees legally working in Thailand, provided they hold the appropriate work permit and visa.Question 3. How long is the probationary period under Thai law, and how can probationary employees be terminated?Probation Period – Thai law does not prescribe or limit the length of the probation period. Employers and employees may agree on any reasonable length.Termination of On-Probation-Employee – It is worth noting that termination during probation period is legally treated as a termination of an indefinite employment contract. Accordingly, the employer must give proper advance notice (one pay cycle) or payment in lieu of advance notice in accordance with the LPA. Question 4. What are “Work Rules” under the Thai labor law?Under Section 108 of the LPA, employers with 10 or more employees must establish written Work Rules in Thai within 15 days and make them accessible at the workplace. The Work Rules must cover:Working days and hours;Holidays and wage payment;Overtime;Leave;Disciplinary measures and penalties;Grievance procedures; andTermination, including severance payFailure to implement Work Rules may result in a fine of up to THB 20,000. Question 5. What are the minimum wage rates in Thailand for 2025, and how do they differ across regions and professions?As of November 2025, Thailand’s minimum wage ranges from THB 337 to THB 400 per day, depending on the province, as prescribed under the Notification of the Wage Committee No. 14 B.E. 2568 (2025). Examples include:Bangkok, Phuket, Chonburi: THB 400 per dayChiang Mai, Samut Prakarn, Nakhon Pathom: approximately THB 357–380 per dayLower-wage provinces such as Nan, Payao, Nakhon Sawan: THB 337–345 per dayIn addition to these general provincial rates, Thailand also prescribes specific minimum wage rates for certain skilled occupations, based on certified skill standards announced by the Ministry of Labour. Examples include:Industrial Robot Operator: THB 605 per dayTruck Driver: THB 485 per dayElectronics Technician: THB 500 per day Question 6. How should employers handle wage deductions in cases where an employee causes damage?Under Thai law, an employer cannot unilaterally deduct an employee’s salary even if the employee causes damage to company property. Salary deductions are strictly regulated under Section 76 of the LPA, which permits deductions only in limited circumstances such as income tax, social security, provident fund contributions, or contributions to employee welfare funds.Where damages are caused by an employee, wage deduction is allowed only if the employee provides explicit written consent. Without such consent, the employer must not deduct wages, even if the damage appears clear, intentional, or negligent. In cases where consent is not obtained, the employer must seek compensation through appropriate legal processes rather than making unilateral deductions. Question 7. What should employers know about retirement in Thailand?Under Thai law, the retirement age is primarily determined by agreement between the employer and employee, as reflected in the company’s work rules, or employment agreement. If the employer specifies a retirement age below 60, that agreed age will apply.Nevertheless, if the employer sets a retirement age above 60, or does not specify any retirement age, employees have the right to elect to retire at 60 years of age, and the employer must honour this request.Retirement is legally treated as a form of termination initiated by the employer, meaning the employee is entitled to statutory severance pay based on their length of service pursuant to Section 118 of the LPA.It is also important to note that if an employer rehires an individual who has already retired and received statutory severance pay, the new engagement is treated as a new employment relationship. The employee’s previous years of service are not carried over, and calculations for severance pay and other seniority-based entitlements must be based solely on the new period of employment.Question 8. Looking ahead, what labour-law themes should employers in Thailand keep on their radar?A key legislative development that employers should closely monitor is the new amendment to the LPA, which expands maternity and paternity leave entitlements. This amendment will come into force on 7th December 2025. The table below highlights the key differences between the current law and the new provisions.Total maternity leave entitlement: (Current Law) 98 days, (New Law) 120 days Full paid maternity leave: (Current Law) 45 days, (New Law) 60 daysAdditional leave for cases where the newborn has illness or disability: (Current Law) Not available, (New Law) 15 days Spousal leave to support childbirth (paternity leave): (Current Law) Not available, (New Law) 15 days In addition to the above amendments, employers should also be aware that another draft amendment to the LPA is currently open for public hearing. Key proposed changes include:reducing the maximum working hours from 48 hours per week to 40 hours per week;increasing the minimum weekly rest from one day to two days; andrevising annual leave entitlements so that employees who have completed 180 days of continuous service will be entitled to at least 10 days of annual leave per year (instead of the current 6 days after one full year of service).Authors:Bunnasomboon Chaiparinya  │Partner & Head of Corporate Department  │E: [email protected] Akaraphasit  │ Associate  │E: [email protected] Sawastham │Associate  │E: [email protected]

Thailand continues to be one of the most attractive destinations in Southeast Asia for educational investment, particularly for international schools, bilingual schools, specialized academies, and vocational institutions. With the increasing demand for high-quality education, together with Thailand’s growing expatriate and international business communities, many foreign education groups are actively exploring opportunities to establish educational institutions in Thailand. However, the establishment and operation of a private school in Thailand is a highly regulated activity under Thai law. In practice, foreign investors must carefully structure their investment, shareholder arrangements, and management framework to ensure compliance with the Ministry of Education’s requirements (so-called “MOE”) while still maintaining practical operational control and protecting their commercial interests. This article highlights several key legal and practical considerations that foreign investors should be aware of when establishing a private school in Thailand. Why Legal Structuring Is ImportantOne of the most important considerations for foreign investors or school operators is that the operation of a private school is generally regarded as a restricted business activity under Thai law.The Private School Act B.E. 2550 (2007) (and its amendments) clearly stipulates that a juristic person that is eligible to apply for a license to establish a private school shall:a)   be a limited company registered under Thai law; b)   have a majority number of shares held by Thai shareholders; c)   have not less than half of Thai shareholders; and d)   have a Thai authorized director(s) who, among other requirements, is 20 years of age or above, possesses at least a Bachelor’s degree, and has not been imprisoned by a final court judgment.As a result, foreign investors are typically unable to directly own or control the private school operator in the same manner as ordinary commercial businesses.Common Structuring Approaches for Foreign InvestorsGiven the above foreign restrictions, proper legal structuring is critically important. In practice, foreign investors commonly consider various structures to protect their commercial interests while remaining in compliance with Thai regulations. Such structures may involve:establishing a joint venture company (so-called “JVCo”) having Thai majority-owned structure;implementing reserved matters and management control mechanisms;appointing foreign representatives in academic and operational roles;separating educational operations from intellectual property ownership;licensing curriculum, trademarks, and educational systems to the JVCo; andimplementing governance mechanisms relating to finance, approval authority, and operational standards.However, these arrangements must be carefully prepared to avoid any issues relating to nominee shareholding arrangements, which are prohibited under Thai law.Licensing ProcessThe establishment of a private school requires approval and licensing from the Office of the Private Education Commission – Ministry of Education (“OPEC”).The licensing process generally involves the submission of:Corporate information and documents of the applicantCurriculum (i.e. Thai, bilingual, international, or specialized educational program)School Charter (i.e. educational objectives and philosophy, financial evidence, management structure, uniform, etc.)Building permits and safety compliance documentationQualifications of the authorized director(s)The estimated timeline for applying the school license would be approximately 4 – 6 months. Employment and Immigration MattersUnder the laws, at least 30 days prior to the school operation commencement date, the school must:a)   hire teachers and educational personnel in a number proportionate to the student population, depending on the type of school, for example, an international school, as follows:Nursery: 1 teacher and 1 caretaker per 20 studentsKindergarten: 1 teacher and 1 caretaker per 20 studentsPrimary School: 1 teacher per 25 studentsMiddle and High School: 1 teacher per 30 studentsb)   appoint the management positions (i.e. the school executive board, consisting of school license holder’s representative, school director, school manager, and teacher & parent representatives).Private schools employing foreign teachers and administrators must also comply with Thai labor and immigration regulations. This typically includes:work permit applications;visa arrangements;teacher licensing requirements;employment agreements;personal data protection compliance; andsocial security and tax obligations.Nevertheless, please note that a school director who looks after and takes responsibility for the administration and management of the school shall be of Thai nationality, have the required qualifications and not be subject to the prohibitions set forth for an educational institute administrator, and be able to perform his/her duties full time for such school.Separate Juristic PersonOnce the school license has been obtained, such school shall become a juristic person from the date of receiving such license, and the license holder (i.e. applicant) shall become a representative of such school. After the school becomes a juristic person, the license holder shall proceed to: a)   transfer the ownership, right of possession over the land and immovable properties which are component parts of the land, right of superficies, usufruct or lease right, free from any encumbrance as indicated in the application for the license; and b)   transfer money and other properties being the capital other than the land to the school. The school executive board may appropriate remuneration derived from the operation of the school to the license holder as it deems appropriate. Final ThoughtThe establishment of a private school in Thailand involves a combination of corporate, regulatory, educational, employment, and operational considerations. For foreign investors, one of the most critical aspects is designing a compliant shareholding and management structure that satisfies the Ministry of Education’s requirements while adequately protecting the investor’s commercial interests.A properly structured arrangement may help foreign investors:mitigate regulatory risks;avoid nominee-related concerns;maintain operational oversight;protect intellectual property and educational systems; andfacilitate long-term business sustainability. For further information, please contact Mr. Bunnasomboon (Aaron) Chaiparinya, Head of Corporate Department, email: [email protected]

In the realm of arbitration, where disputes are resolved outside traditional courtrooms, the exchange of documents can be essential for ensuring fairness and efficiency. Depending on the nature of the arbitration, document production, where necessary, offers parties the opportunity to request and present crucial information that supports their positions, enhancing their credibility and assist the parties in securing a favourable arbitration outcome. Depending on the nature of the case, the disclosure of relevant documents can be pivotal, promoting transparency and enabling arbitrators to make well-informed decisions. To ensure that parties make the correct requests for documents that will support their case and that the documents produced by the parties do not fall under exceptions such as confidentiality or attorney-client privilege, it is crucial to approach the document production step with meticulous care and attention to detail. Properly navigating this stage involves understanding the specific requirements and limitations of document disclosure in arbitration. Parties must be well-versed in the applicable rules and guidelines to avoid common pitfalls and ensure that their document requests are both appropriate and strategic. This careful approach not only strengthens the integrity of the arbitration process but also helps in achieving a fair and just resolution. Procedure for Document Production The process of document production in arbitration typically follows these steps: Initial Request: One party initiates the process by requesting relevant documents from the opposing party. The initial request must contain materiality and relevance of such documents to the case and arguments raised in the proceedings. It should also be specific enough so that the opposing party can identify the document being requested. Response and Objections: The responding party must respond within a specified time frame, either producing the requested documents or stating objections based on grounds such as privilege, irrelevance or undue burden. Arbitrator's Intervention: If disputes arise over the scope or relevance of requested documents, the arbitrator may intervene to resolve disagreements and ensure compliance with procedural fairness. Review and Use: Once documents are exchanged, parties review them to prepare their case, identify key issues, and potentially use them during hearings or settlement discussions. Exceptions to Production of Documents While document production is generally essential, there are certain exceptions that may be relied upon, making the review of all documents crucial. Some key exceptions include: Confidentiality: Documents containing sensitive or proprietary information may be protected from disclosure to preserve privacy and competitive advantage. Attorney-Client Privilege: Communications between a client and their legal counsel that are intended to be confidential and pertain to legal advice are typically exempt from disclosure. Work Product Doctrine: Materials prepared by or for an attorney in anticipation of litigation may be protected to safeguard the attorney's strategic planning and legal analysis. Relevance and Materiality: Only documents that are directly relevant and material to the issues in dispute should be produced, avoiding unnecessary or overly burdensome requests. Careful consideration of these exceptions is vital to maintaining the integrity and efficiency of the arbitration process. Reviewing documents meticulously ensures that privileged or irrelevant information is not disclosed, while relevant and necessary documents are appropriately shared. Non-disclosure and mis-declaration in Document Production Misuse or mistakes in document production can have severe consequences in arbitration. Errors such as non-disclosure or mis-declaration of documents can undermine the integrity of the process and lead to significant repercussions. For instance: Sanctions and Penalties: Parties that fail to disclose relevant documents or intentionally withhold information may face sanctions or penalties imposed by the arbitrators. Adverse Inferences: Arbitrators may draw negative inferences from a party's failure to produce required documents, potentially weakening that party's position in the dispute. Delayed Proceedings: Mistakes in document production can cause delays, as parties may need additional time to rectify errors, resubmit documents, or address disputes over document requests. Damage to Credibility: Parties that are found to have mishandled document production may suffer damage to their credibility and reputation, both in the current arbitration and in future legal matters. Unfavorable Outcomes: Ultimately, improper document production can lead to unfavorable outcomes, as arbitrators rely on complete and accurate information to make informed decisions. Given these potential consequences, it is essential for parties to approach document production with diligence and precision. Ensuring thorough and accurate disclosure not only upholds the fairness and efficiency of the arbitration process but also protects the interests and credibility of the parties involved. Conclusion In conclusion, document production stands as a pivotal aspect of arbitration, ensuring transparency, fairness, and efficiency in dispute resolution. By balancing disclosure with protections for privileged and confidential information, arbitrators help parties navigate towards a just and efficient resolution.

JTJB International Lawyers Co., Ltd. would like to inform our clients and business partners that the Department of Intellectual Property of Thailand (DIP) has officially updated its trademark classification practice by adopting the Nice Classification, 13th Edition, which will take effect in 2026.Under the 13th Edition of the Nice Classification, several goods and services have been reclassified to better reflect current commercial and technological developments, as well as to align Thailand’s practice with international trademark standards. Notably, certain categories of goods have been transferred to new classes, such as eyewear-related products moving from Class 9 to Class 10, emergency and rescue vehicles from Class 9 to Class 12, and electrically heated clothing and accessories from Class 11 to Class 25. Additional goods have also been reallocated across various classes under the revised classification framework.These changes may have practical implications for trademark owners, particularly in relation to new trademark filings, amendments to pending applications, and the scope of protection of existing trademark registrations. Accurate classification of goods and services will be increasingly important to avoid procedural issues, potential objections, or unintended limitations on trademark rights.We, therefore, recommend that trademark owners review their existing trademark portfolios and future filing strategies in light of the implementation of the Nice Classification, 13th Edition. A proactive approach will help ensure continued compliance with the updated requirements and maintain effective trademark protection in Thailand.Please contact our Intellectual Property team at JTJB International Lawyers Co., Ltd. for further advice, portfolio review, or assistance with trademark filings and amendments under the updated Nice Classification.We remain pleased to support our clients in navigating these regulatory developments and in safeguarding their valuable intellectual property rights.Authors:Pattaravadee Kongcharoenniwat  │Partner  │E: [email protected] Thabarabasi  │Senior Associate │E: [email protected]

In the intricate world of international trade, maritime transport is a cornerstone, facilitating the movement of goods across vast distances. Carriers engaged in this industry enter into contracts of carriage, committing to transport goods by sea from one country to another in exchange for freight. These contracts typically include terms and conditions related to the carriage of goods, liability, delivery obligations, and, critically, dispute resolution mechanisms. The key element in this industry is the Bill of Lading (B/L), a pivotal document that serves as a receipt, a document of title, and evidence of a carriage contract. B/L often includes the choice of court clause, which designates a specific court for resolving disputes. Maritime transport disputes frequently arise from issues such as cargo damage or loss, delays, and disagreements over freight charges. The international nature of maritime transport complicates these disputes, often involving parties from different jurisdictions with varying legal frameworks. Understanding the implications of the choice of court clauses in B/Ls under Thai law is crucial for businesses engaged in maritime trade with Thailand. The Bill of Lading in Thailand B/L is an essential document in maritime transport that confirms the receipt of goods for shipment and outlines the terms of the carriage contract. It can also act as a transferable document of title, allowing ownership of the goods to be transferred during transit. For businesses involved in maritime transport with Thailand, understanding how B/Ls are treated under Thai law is essential for managing disputes and ensuring smooth operations. Legal Framework In Thailand, the primary legislation governing B/Ls is the Carriage of Goods by Sea Act, B.E. 2534 (1991) (CGSA). This Act aligns with international conventions, regulating the rights and obligations of parties involved in the carriage of goods by sea. According to Section 3 of the CGSA, a B/L is defined as a document issued by the carrier to the shipper as evidence of a contract of carriage and receipt of goods, with the carrier undertaking to deliver the goods to the rightful recipient upon surrender of the document. Roles of a Bill of Lading 1. Evidence of Contract: It confirms that the freight forwarder will transport the goods to the specified destination and deliver them to the consignee under the terms of the carriage contract. 2. Receipt of Goods: It acts as a receipt, indicating that the carrier has received the goods, detailing their quantity and specifics. 3. Document of Title: It represents ownership of the goods, allowing the holder to claim the goods or transfer ownership to another party. Jurisdictional Challenges and Court Choices Disputes involving B/Ls often entail jurisdictional challenges, particularly when the choice of court clause specifies a foreign court. Such clauses aim to provide clarity and predictability but can complicate enforcement if the designated court is outside Thailand. Thai Jurisdiction The Intellectual Property and International Trade Court (IPITC), which is the specialized court established under the Act for the Establishment of and Procedure for Intellectual Property and International Trade Court, B.E. 2539 (1996), has jurisdiction with regard to international trade and intellectual property disputes, including those arising from maritime contracts. This specialized court ensures that aforesaid disputes are resolved efficiently in accordance with international standards and procedures to lead the party to justice. Enforceability of Choice of Court Clauses in B/L Thai courts generally respect the choice of court clauses in B/Ls. However, enforcing these clauses can be challenging if the chosen jurisdiction is outside Thailand. The enforceability depends on factors such as compliance with international treaties and Thai legal standards. An illustrative case is Supreme Court Judgment No. 3882/2006. In this case, the B/L specified the Hong Kong City Court for dispute resolution. However, the IPITC in Thailand was deemed competent to adjudicate the matter. The dispute involved damages for the loss or damage of goods during the sea transport party's nationality between Thailand and Spain. The Supreme Court ruled that, since the contract of carriage was executed in Thailand and Thai law was applicable, the IPITC had jurisdiction to consider and resolve the dispute. This decision highlights the authority of Thai courts to handle disputes even when a B/L specifies a foreign court, especially when significant aspects of the case are connected to Thailand, such as the place occurring ground of dispute, domicile of the party, or the place of the majority evidence for consideration and resolution the case as same the competent court. Conclusion Understanding the role of the Bill of Lading under Thai law and the associated jurisdictional issues is crucial for effectively managing maritime disputes. While B/Ls are essential documents in international trade, the disputes arising from them can be complex, particularly when jurisdictional clauses are involved. Thai legislation, including the Carriage of Goods by Sea Act and the Act for the Establishment of and Procedure for Intellectual Property and International Trade Court, provides a robust framework for resolving such disputes. The Supreme Court's decision in Judgment No. 3882/2006 underscores the capability of Thai courts to adjudicate maritime disputes, ensuring that legal resolution remains accessible and consistent with Thai legal standards.

As demand for cloud computing, AI infrastructure, and regional data hubs continues to grow, Thailand has emerged as an increasingly attractive destination for data center investments in Southeast Asia. However, from a legal and regulatory perspective, the key challenge for foreign investors is not technical capability, but structuring—particularly how to lawfully operate a data center business and data center related-business(such as engineering service) in Thailand while maintaining 100% foreign ownership. Under Thailand’s Foreign Business Act B.E. 2542 (1999) (FBA), many service-related businesses are restricted or subject to foreign ownership limitations. Against this backdrop, Thailand Board of Investment (so-called “BOI”) promotion has become the most practical and reliable legal solution for foreign data center operators seeking full ownership and operational flexibility in Thailand. This article outlines why BOI promotion matters, how it applies to data center businesses, and the key structuring issues foreign investors should consider at an early stage. Why Data Center Businesses Face Foreign Ownership Issues From a legal standpoint, a data center business does not automatically fall within a single regulatory category. Depending on how the business model is structured, activities may be viewed as: Infrastructure or facility operation; Data processing or hosting services; and/or Managed IT or cloud-related services. If improperly structured or broadly defined, certain service components may fall under restricted service businesses under the Foreign Business Act, triggering a 49% foreign ownership cap or the need for a Foreign Business License (“FBL”) – a route that is often time-consuming and uncertain in outcome. For capital-intensive projects such as data centers, this regulatory uncertainty can materially affect investment feasibility, financing, and exit planning. BOI Promotion A Statutory Exception to Foreign Ownership RestrictionsBOI promotion offers a statutory exemption from foreign ownership restrictions under the FBA. For qualifying activities, a BOI-promoted company may be 100% foreign-owned, even if the underlying business would otherwise be restricted. Importantly for data center operators, BOI has expressly recognised data center activities as eligible promoted businesses, subject to specific technical and investment criteria.From a legal structuring perspective, BOI promotion is often the cleanest and most defensible route for foreign investors seeking long-term certainty. Key BOI Benefits for Data Center Operators For foreign data center investors, BOI promotion offers several critical advantages:Foreign Ownership: BOI-promoted companies are exempt from foreign shareholding limits, allowing full foreign control without nominee risks or complex joint venture arrangementsConduct Restricted Activity: Promoted companies may engage in businesses otherwise restricted under the FBA without applying for a Foreign Business License.Tax Incentives: BOI incentives include (a) Corporate income tax exemptions, and (b) Import duty exemptions on machinery and equipmentLand Ownership: Promoted companies will be permitted to own land required for their promoted business activities.  Visa & Work Permit Facilitation: BOI promotion simplifies immigration and work permit processes for foreign executives and technical specialists.BOI Requirements for Data Centre Projects While BOI is generally receptive to data center investments, approval is not automatic. Applications are assessed on both legal and technical grounds. Common requirements include:Infrastructure and TechnologyTier-standard data center design (e.g. redundancy, uptime, disaster recovery);Robust cybersecurity and system resilience measures;Scalable infrastructure to support future digital demand.Energy and Environmental RequirementsGiven the energy-intensive nature of data centers, BOI strongly encourages:Energy-efficient systems;Use of renewable or clean energy sources; andEnvironmental impact mitigation measures.Legal and Regulatory ComplianceOperators must ensure compliance with:Personal Data Protection Act (PDPA);Cybersecurity laws and sector-specific regulations;Licensing and zoning requirements at the local level.Projects demonstrating alignment with ESG and sustainability principles may receive preferential considerationBased on the current requirements of the BOI, the project will be eligible for the higher tax privileges if the data center meets their targeted criteria, including: Having Power Usage Effectiveness (“PUE”) not exceeding 1.3Having Minimum IT load of 2 MWProvide services such as server co-location, managed service, customer’s backup service, disaster recovery services, data hosting serviceHaving at least 4 systems of high-speed telecommunication (at least 3 domestic systems), each with at least 10 Gbps capacity, and at least 60 Gbps combinedObtaining ISO/IEC 27001Employing at least 50% Thai personnel in management/expert positions From a legal standpoint, it is critical that the scope of business activities stated in the BOI application aligns with the company’s actual operations and future expansion plans. Overly narrow descriptions may limit growth, while overly broad descriptions may raise regulatory concerns. Early legal assessment is critical to avoid regulatory delays post-approval.Structuring Considerations Beyond BOI Approval Foreign investors often focus heavily on BOI approval itself, but experienced deal counsel will look beyond approval to long-term implications, including: Land acquisition vs long-term lease structures; Power purchase agreements and utility arrangements; Change of shareholding or control restrictions under BOI conditions; and Ongoing compliance obligations and reporting to BOI. Why BOI Is Usually Preferable to Other Legal Routes In practice, alternative structures, such as (i) applying for a Foreign Business License, or (ii) forming a Thai-majority joint venture, often introduce approval risk, control limitations, or long-term legal exposure. For data center businesses involving substantial capital investment and long asset lifecycles, BOI promotion typically offers greater regulatory certainty, investor protection, scalability, and incentives. Key Takeaways Data center businesses in Thailand can raise foreign ownership and regulatory issues if not properly structured. BOI promotion provides a clear legal pathway for 100% foreign ownership. Early classification and structuring are critical to avoid future regulatory and M&A complications. Legal advice at the planning stage can materially affect approval timelines, operational flexibility, and exit strategy. Final Thought As Thailand continues to position itself as a regional digital infrastructure hub, data center investments are expected to increase in scale and complexity. For foreign investors, success often depends not only on technology and capital, but on getting the legal structure right from day one.
