Vietnam is becoming a rising star in ASEAN countries in terms of economic development. Thanks to the development, we have seen two dominant investment streams in the jurisdiction: foreign investors significantly invest into Vietnamese market while Vietnamese enterprises start their investment or business oversea.

When working with our clients from both investment streams, we recognise their following legal concerns:

1). Who/what are Vietnamese lawyers or Vietnam law firms they should contact to get the prompt, reliable and cost-effective solution?

2). Are the Vietnamese lawyers or Vietnam law firms qualified?

3). How startup companies have their own in-house lawyers by using retainer services?

4). Do they have enough budget to spend on the legal matter?

5). Could they receive a full legal service (all in one legal service) from such Vietnam law firm?

All the aforementioned matters shall be handled by ASL Law Firm, a full business Vietnam law firm. The following features make ASL Law Firm become the most recommended Vietnam law firm for enterprises:

  • Shortening the time of finding the right, experienced lawyers for clients.
  • Immediately connecting Vietnamese enterprises with our selected foreign lawyers when they do business abroad.
  • ONE inquiry from clients receive TWO independent advices from our two lawyers, if required. Clients do not need to shop around. Our two lawyers shall independently send the clients their separate legal proposal. Then, after receiving the advices, the clients shall select their suitable lawyer.
  • Saving our clients budgets due to our strong constraints between our lawyers.

  • Creating bridge between clients and successful lawyers

It is proud that ASL Law Firm has successfully gathered the leading lawyers and legal experts in comprehensive legal fields. Therefore, ASL Law Firm could provide all in one legal services to our clients. Our legal services include:


The reasons why ASL LAW can guarantee such a thing is its team of experienced lawyers from Vietnam and many countries where Vietnamese businesses are active, such as Australia, Malaysia, Singapore, China, Cambodia, Laos, Myanmar, Japan, South Korea, the US, and Canada. They are all experienced lawyers in the fields affecting the operation of most businesses, such as anti-dumping, mergers and acquisitions, real estate, finance, banking, foreign investment, arbitration, and intellectual property. Many foreign businesses who come to Vietnam as well as Vietnamese enterprises investing and doing business abroad are often confused about on-site legal issues. This is especially true for startups or those without their own legal department. ASL LAW’s mission is to support these businesses to operate in accordance with the applicable laws, to avoid risks, and minimise damage.

In particular, as a member of the International Bar Association (IBA) as well as having relations with investors from many economic powers such as Singapore, Malaysia, China, Japan, South Korea, Australia, and the US, ASL LAW also brings quality investors to do business in Vietnam – and helps Vietnamese businesses expand abroad.


Each legal field provided by ASL Law Firm is led by at least two experienced and senior lawyers. In principle, they are top tier lawyers in their field. You could see the lists of our lawyers here.

– Vietnam Investment Review: ASL Law Legal superconductor for businesses

“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.”
