Pham Duy Khuong, Founder and Managing Director

Founder and Managing Director Pham Duy Khuong explains how leading Vietnamese firm ASL LAW is adapting to clients’ changing needs

What do you see as the main points that differentiate your firm from your competitors?

ASL Law, a full-service Vietnam law firm, includes Associates of Successful Lawyers from Vietnam and other countries. We are the pioneer in creating a full-service law firm in which all fields are managed by reputable lawyers and experts to ensure our consulting quality. Therefore, ASL LAW can be a common service portal for all legal needs of investors and businesses. Our main purpose is to provide the most practical, efficient and lawful advice or legal services to clients.

Which practices do you see growing in the next 12 months? What are the drivers behind that?

The field of anti-dumping and countervailing is one of the areas of development in the coming time as Vietnam is integrating deeply into the world market and many countries consider this an effective measure to protect their domestic businesses.

In addition, cross-border trade disputes will also have a significant development due to the impact of the COVID epidemic, causing the parties unable to perform or finding ways to delay their obligations to the other party. In parallel with such disputes, we can see the development of the conciliation of disputes between the parties.

Furthermore, there are disputes over intellectual property related to selling counterfeit and infringing goods on online platforms, e-commerce platforms or across borders. The COVID epidemic makes online transactions the preferred choice of users. Followed by the preference, counterfeit and infringing goods are promoted through this channel.

What’s the main change you’ve made in the firm that will benefit clients?

ASL LAW continues to expand recruitment and invite cooperation of talented lawyers and experts in various fields to ensure that our solutions offered to Clients are highly practical and at the same time, ensure attorney’s fees suitable for clients.

ASL LAW keeps digitizing documents and dossier, applying technology to process and manage clients’ works. This ensures that ASL LAW’s attorneys always have access to complete their works whether working from home or at office. This helps ASL LAW’s consulting and activities during the COVID epidemic go smoothly and effectively.

In addition, ASL LAW continues to promote its strengths as a pioneer law firm in cross-border disputes and commercial agreements through professional training sessions for lawyers, multinational members of ASL LAW.

Is technology changing the way you interact with your clients, and the services you can provide them?

Although there is no statistics on the impact of technology on the legal field in Vietnam, we believe that applying technology in legal works always brings many positive improvements. Especially improvements related to the management of records/cases, the ability to access records/cases remotely. In addition, technology also helps law firms have a more specific view of which direction the law market in Vietnam is operating and respond appropriately.

Can you give us a practical example of how you have helped a client to add value to their business?

ASL LAW always focuses on specific groups of clients so that we can give respective legal warnings/notes to the business activities of that clients. The goal is to help our clients be proactive in preparing for or changing before amended laws become effective.

In addition, a large number of clients of ASL LAW are foreign investors, startup so ASL LAW always tries to connect them together so that they can expand their potential cooperation.

Are clients looking for stability and strategic direction from their law firms?

Clients’ loyalty majorly depends on strategy of law firms. The nature of the legal field is that the clients desire to find a stable legal partner provided that the legal partner gains the trust of the clients. ASL LAW always creates every policy of serving clients or maintaining client’s relationships based on such trust building. In addition, in order to ensure a sustainable relationship between the clients and ASL LAW, we set ourselves the task of understanding and proactively supporting the clients. Because after all, every relationship that wants to be sustainable cannot be based on just one way, but on a positive and understanding interaction between two parties.

Where do you see the firm developing in the future?

ASL LAW’s success proves that there are more than a few Vietnamese law firms that are strong enough to cover complicated multinational legal cases. This also harangues the end of the times when Vietnamese law firms were sidekicks to more established international counterparts due to foreign language limitation, lack of standard legal drafting skills, lack of knowledge about international legal systems, or limited connectivity.

Although ranking among the most prestigious law firms in Vietnam, ASL LAW has no intention of stepping off the accelerator, as ASL LAW will soon grow its presence Southeast Asia-wide, proving the maturity and adaptability of a Vietnamese law firm.
