Mr. Bunnasomboon Chaiparinya (Aaron), Partner / Head of Corporate Department
Bunnasomboon Chaiparinya (Aaron) is a Partner and Head of Corporate Department at JTJB International Lawyers Co., Ltd. (“JTJB Bangkok”), situated in Bangkok, Thailand, with extensive experiences in advising on high-profile domestic and international M&A, corporate, and cross-border transactions.
What do you see as the main points that differentiate [law firm name] from your competitors?
JTJB Bangkok distinguishes itself by combining regional reach with a client-focused approach. As part of the JTJB global network in 9 countries, along with membership in ADVOC – the leading international network of independent law firms in 73 countries – and IR Global, a network of quality boutique firms worldwide, we are uniquely positioned to deliver seamless cross-border expertise while maintaining the agility and personal service of a focused Bangkok practice.
Unlike larger firms where clients may feel like one of many, our partners remain personally engaged in every matter, ensuring continuity, trust, and tailored strategies to each client’s needs.
Our clients benefit from advice that is not only legally sound but also pragmatic, cost-efficient, and grounded in industry-specific knowledge, particularly in shipping, international trade, corporate law, and dispute resolution. This balance of global capability and personal care allows us to offer a service that is both highly professional and deeply attentive – a distinction that sets us apart in the Thai legal market.
Which practices do you see growing in the next 12 months? What are the drivers behind that?
In the next 12 months, I anticipate continued growth in mergers & acquisitions, corporate restructuring, and foreign direct investment because Thailand remains an attractive investment destination in Southeast Asia due to its strategic location, regional trade agreements, and government support measures, particularly through the Board of Investment of Thailand (“BOI”) and Eastern Economic Corridor Development Plan (“EEC”).
Additionally, I expect ESG-related compliance, data privacy, and digital (AI) regulations to play a larger role. With increasing cross-border transactions, businesses are paying closer attention to sustainability obligations and regulatory risks, which will drive demand for legal services in these areas.
Finally, dispute resolution and arbitration will likely see an uptick, as more parties look for efficient mechanisms to resolve cross-border commercial disputes amid geopolitical uncertainties.
What's the main change you've made in the firm that will benefit clients?
While direct internal restructuring was not publicly detailed beyond historical merger activity, our firm continues to benefit from a strengthened structure capable of integrated, high-value client service. Following the 2023 merger with AWP & Alliance, JTJB Bangkok expanded its capabilities, widened its partner base, and increased staff strength—lifting both capital market and IP capabilities through deeper resources and cross-practice collaboration. This bolstered expertise, paired with the firm’s award-winning track record, underscores a strategic transformation towards greater industry breadth, operational responsiveness, and enhanced client alignment.
Is technology changing the way you interact with your clients, and the services you can provide them?
Technology has significantly transformed the way we interact with our clients and the services we provide. On the client side, secure video conferencing and digital collaboration tools now allow us to engage with international clients seamlessly, removing traditional barriers of time and distance.
Within Thailand, the growing adoption of e-filing systems has enabled us to expedite processes, reduce paperwork, and deliver faster results at a lower cost. We have also embraced digital knowledge management systems, which enhance the speed and accuracy of our legal advice. These developments allow us to provide the same level of responsiveness and sophistication as much larger international firms while maintaining greater flexibility and efficiency.
Can you give us a practical example of how you have helped a client to add value to their business?
A practical example of how we helped a client add value to their business is our successful work with one of Thailand’s most successful start-up laundry and dry-cleaning franchises. We have been assisting this client in restructuring its subsidiary and entering into an acquisition agreement with a publicly listed company in a transaction valued at approximately THB 1.05 billion.
The restructuring involved an entire business transfer procedure (“EBT”), moving all assets, contracts, debts, and employees from the subsidiary to the parent company. This approach was carefully designed to significantly minimize the tax liabilities associated with transferring assets between the client’s subsidiaries.
Beyond the restructuring, we advised the client in negotiating with the investor and finalizing key legal documents, including the Term Sheet, Shareholder Agreement, and Share Subscription Agreement. We also coordinated with the investor’s legal team during the due diligence process.Through this work, we helped the client not only achieve a smooth and tax-efficient transaction but also position the company for sustainable growth and strategic expansion.
This project illustrates how we add tangible business value by combining legal expertise with strategic, commercially minded solutions.
Are clients looking for stability and strategic direction from their law firms - where do you see the firm in three years’ time?
Clients increasingly expect their legal advisers to provide both stability and strategic foresight in a rapidly changing regulatory and business landscape. At JTJB Bangkok, we are committed to meeting these expectations by combining cross-border capability with the continuity and trust that come from direct partner involvement.
Over the next three years, I envisage the firm consolidating its position as a leading ASEAN gateway for cross-border investments, shipping and international trade, corporate transactions, and dispute resolution for both Thai and international clients. Our focus will be on strengthening industry-focused practice groups, expanding advisory services in areas such as foreign investment, regulatory compliance, and ESG, and investing in technology and talent development to enhance efficiency and responsiveness. Additionally, we plan to deepen our integration within the JTJB global network, ADVOC, and IR Global, enabling us to deliver cross-border solutions with agility and precision.
Through these initiatives, we aim to reinforce our role as a trusted and forward-looking partner, providing clients with stability, clarity, and strategic guidance to support their long-term success.
