Koh Samui nominee probe expands to 60 cases and 88 suspects

What the August operation actually covered

Authorities said they had analysed 12,906 active juristic persons on Koh Samui. Of those, 8,254 had foreign shareholders and 875 were identified as showing characteristics that could warrant nominee scrutiny. That screening figure is not a finding that 875 businesses broke the law: police then narrowed the investigation to 61 companies selected for deeper action.

The Royal Thai Police said those targets were linked to 42 land plots and properties covering more than 33 rai, with an estimated combined value of around 1.5 billion baht. Investigators recorded 60 cases involving 88 suspects — 26 Thai nationals and 62 foreigners. Courts issued 37 search warrants and 62 arrest warrants for foreign suspects, while police reported 27 arrests on the day of the operation.

Some same-day media reports carried lower interim totals of 59 companies, 37 plots and roughly 1.2 billion baht. The more detailed police release gives the larger figures of 61 targeted companies, 42 plots and about 1.5 billion baht, so those are the figures used here while noting that early counts differed between reports.

A Thai company with foreign shareholders is not automatically a nominee company

Foreign participation in a Thai company is not, by itself, evidence of an illegal nominee arrangement. The enforcement focus is on structures in which Thai shareholders are alleged to be owners only on paper, without genuine investment or control, while effectively holding interests for a foreign beneficiary in order to bypass restrictions on land ownership or regulated business activities.

Police said the targeted groups included businesses connected with buying, developing, selling and renting villas, as well as entities allegedly used to support work permits or business visas without corresponding genuine operations. Those allegations concern the specific companies and suspects under investigation. They should not be read as a finding that every villa held through a Thai company, or every company with foreign shareholders, is unlawful.

For a buyer or existing owner on Koh Samui, the practical issue therefore goes beyond the shareholding percentages shown on a company extract. The source of capital, who actually exercises control, the role of each shareholder and whether the company conducts the business it claims to conduct can all become material when authorities examine the structure.

Scrutiny continued after the raid

On August 25, authorities in Surat Thani said inspections and legal proceedings involving suspected nominee businesses were continuing on Koh Samui and Koh Phangan. Officials were linking information from the Department of Business Development, Land Department, Revenue Department, labour authorities, provincial administration and law enforcement to assess individual cases.

That makes the August 15 operation part of a broader enforcement process rather than a one-day raid. For someone who already owns a villa through a company, or is considering such a purchase, the development increases the importance of being able to document where the capital came from and what each shareholder genuinely does. It does not establish that any particular private structure is illegal without its own facts being examined.
