Since January 2026, Thailand’s enforcement of the Foreign Business Act B.E. 2542 (1999) has been transformed. Thailand’s 2026 Nominee Crackdown What and Why, a 55-page memorandum has been produced examining this shift in full — not as commentary for or against the policy, but as a dispassionate legal account of where the prohibition on nominee shareholders comes from, how it is now being applied, and what it means in practice for businesses already operating in Thailand.
The statutory prohibition itself is not new. It has existed for 25 years. What has changed, and what is explained in detail in the memo, is enforcement. Beginning in January 2026, the economic reality behind a shareholder register began to be examined far more closely than the formal 49/51 ownership split ever was.
Across ten chapters, the following ground is covered.
The historical foundation is traced first — how the 1972 Alien Business Act was replaced by the 1999 Foreign Business Act, why the negative-list system was adopted, and how this created the conditions in which nominee structures became widespread across tourism, hospitality, and property sectors.
The 2026 enforcement timeline is then laid out month by month:
DBD Order No. 2/2568, effective January 2026, governing incorporations; and DBD Order No. 1/2569, effective April 2026, introducing the mandatory Investment Confirmation Letter — a declaration carrying direct references to Thai Penal Code provisions on false statements to public officials and false entries in official records.
The legal framework is analysed in depth, including Sections 36 and 37 of the FBA,
Also described the criminal penalties involved (up to three years’ imprisonment and fines of up to THB 1,000,000), questions of corporate and director liability, and how nominee enforcement now intersects with the Land Code and anti-money laundering legislation.
The investigative methodology used by Thai authorities is explained
How financial capacity is assessed, how the source of funds is traced, how shareholder agreements and corporate governance records are scrutinised, and which red flags are treated as high, medium, or contextual indicators of concern.
Real enforcement actions are examined as case studies, including the January and May 2026 Koh Phangan operations, the Phuket “Villa Andaman” investigation referred to prosecutors, and the expansion of enforcement into Koh Samui and Pattaya.
A practical compliance manual is included for companies already operating in Thailand, with a step-by-step documentation framework and a risk assessment matrix ranging from low to critical.
Lawful alternatives are set out in detail — Foreign Business Licences, BOI promotion, the Treaty of Amity for qualifying US investors, genuine joint ventures, and properly structured preferred shares — so that foreign participation can continue without resort to nominee arrangements.
For anyone holding a Thai corporate structure involving Thai shareholders, or advising clients who do, the full memorandum is available on request.
