Thailand has proposed amendments to the Anti-Money Laundering Act B.E. 2542 (1999) as the country steps up its efforts to combat economic crimes and corruption. One of the primary objectives of the amendments is to enhance the effectiveness of measures curbing the use of nominees to help foreign nationals operate restricted or prohibited businesses in violation of the law. If these proposed updates are implemented, they will substantially strengthen existing legislation related to the use of nominees and bribing government officials, including officials of foreign governments and international organizations. These offenses would be treated as predicate violations under the amended legislation. The draft amendments are currently open for a public comment period, which is set to conclude on April 25, 2025. Highlights of the proposed amendments are detailed below. Predicate Offenses The draft amendments propose adding the concept of a “predicate offense” covering the following: Bribery: Giving, offering, or promising to give assets or benefits to Thai or foreign public officials, or officials of international organizations. Acting as a nominee: Assisting, supporting, or engaging in the business operations of a foreign national who is not permitted to operate that business; jointly operating a business with a foreign national under the guise that it is solely owned by the Thai national; or holding shares on behalf of a foreign national in a partnership, limited company, or any other legal entity to help the foreign national conduct business without the permits required under the Foreign Business Act. Under the draft amendments, Thai individuals or juristic persons who have agreed to take any of these actions, as well as foreign nationals who allow such assistance in their business operations, will be liable for committing a predicate offense under the Anti-Money Laundering Act. The draft proposes a prescription period of 15 years from

On February 26, 2025, Thailand’s National Anti-Corruption Commission (NACC) issued a notification titled “Criteria for Individuals Living Together as Husband and Wife that Are Considered as De Facto Spouses (No. 2) B.E. 2568 (2025).” This new notification, published in the Government Gazette on March 7, 2025, took effect retroactively from January 22, 2025. Prior to this notification, the term “spouses” specifically included “individuals living together as husband and wife” without registering marriage, referring to similar language at the time in Thailand’s Civil and Commercial Code. However, it was unclear whether this term included same-sex and other nontraditional couples. After the Marriage Equality Act revised this language in the Civil and Commercial Code to only refer to “spouses” (with a gender-neutral Thai word), the NACC took the opportunity to issue a new notification that simply replaces any mention of “husband and wife” with “spouses,” thereby removing the ambiguity. As a result, this new notification covers same-sex de facto spouses of politicians and high-ranking officials. These spouses’ assets must now be declared together with the officials’ assets. Additionally, same-sex de facto spouses of state officials are prohibited from engaging in business with the Thai government that may present conflicts of interest. Importantly, the notification also impacts the interpretation of the Office of the Prime Minister’s (OPM) Regulation on the Giving or Receiving of Gifts by Public Officials B.E. 2565 (2022). In this regard, same-sex de facto spouses of government officials are now also prohibited from accepting gifts or other benefits related to official duties. This is because the OPM regulation references the NACC definitions when defining “family members” to include “de facto husband and wife.” Under the OPM regulation, public officials and their supervisors are strictly prohibited from permitting or condoning family members’ acceptance of gifts or other benefits related to
