Thai authorities are cracking down on nominee ownership structures used by foreigners to hold land on Koh Lanta, not because the practice became illegal, but because digital registries now make it easy to enforce a 1954 law that was previou
If you own a house on Koh Lanta through a Thai company, you have probably heard something alarming this year and struggled to find out how much of it is true. The English-language material is mostly law firms advertising, or forum threads where confident strangers contradict each other.
So we asked a lawyer. Sebastien Brousseau has worked with Thai counsel since 2006 and runs ThaiLawOnline. His opening line is the one worth starting from:
"The law that matters is from 1954. What changed in 2026 is not one comma of that law. What changed is that the Thai state started reading its own files."
Nothing became illegal. It stopped being ignored
Foreigners have not been able to own land in Thailand for seventy years, and since 1970 there has not even been a treaty exception. That has not moved.
What changed is the question officials ask. Brousseau puts it like this: the old question was who is on the shareholder list, and if it showed 51 per cent Thai, "the clerk stamped it and everyone went to lunch." The new question is who actually paid for those shares, from which bank account, and can the Thai shareholder prove it.
Most island holding companies cannot answer that, he says, "because the honest answer is that nobody ever paid anything."
Two things made the change possible. In April, twenty-one agencies signed a data-sharing agreement on nominee structures. And the registries went digital, which turns a needle-in-a-haystack problem into a database query. When the business registration department cross-matched its records, it found accounting firms sitting as shareholders in thousands of companies. One accountant, he says, appeared as a shareholder in 212 of them.
"The nominee industry was built for a world of paper filing cabinets, and that world is gone."
What we could confirm, and what we could not
The raids are real and independently reported. Thai media have covered operations on Koh Samui and Koh Phangan targeting nominee networks, including a law office linked to more than 150 companies, with over 100 of them registered at that single address. Brousseau's own description of it is blunter: "That is not a law firm with clients. That is a warehouse."
He also describes a sweep on 15 August in which more than 300 officers visited 61 villa-related companies on Samui in one day. We could not independently confirm that particular operation, so we are reporting it as his account rather than as established fact.
Nothing we found suggests any comparable operation has taken place on Koh Lanta. His view on whether this island is different is short: the law is national, and local land offices vary only in how much paperwork they ask for.
The misconception he corrects most
"My lawyer and my accountant set it up, so it must be legal."
He has been hearing that since 2006. He points out that a developer arrested in the Samui sweep told the press everything had been arranged by a Thai lawyer and accountant, and was charged anyway. Professional advice is not a defence, and in many cases the offices that designed these structures were the same ones supplying the shareholders.
The fear that is overblown
This is the part he wanted journalists to help correct, and it matters if you are lying awake about it.
"They will confiscate my house." Under current law, no. If a structure is found to be a nominee arrangement, the remedy is an order to sell the land within 180 days to a year, with the proceeds going to whoever is entitled to them. As he puts it, a forced sale on a deadline is a bad day, but it is not seizure.
One caution he added himself, for balance: the government has proposed changing the law so unlawfully held land would be forfeited to the State. That is a proposal today, not law. It is also a reason not to leave a problem sitting for years.
On an amnesty: none has been announced and the Prime Minister has said there will be no deals. But his point is that you do not need one, because correcting a structure happens openly through the ordinary Land Office system, at real prices with real taxes. That is not a confession.
If this is you, what to actually do
Three things not to do. Do not panic-sell into a frightened market. Do not sign anything backdated, ever. And do not take the fix currently being sold hardest, which is swapping in better Thai shareholders.
That last one has teeth now. Since 1 August, changing a shareholder requires the incoming Thai shareholder to file three months of their own bank statements proving they paid for the shares, plus a signed confirmation carrying a printed criminal warning. In his words, a replacement nominee "now has to lie on a government form, and the foreign director has to countersign the lie." A mess made carelessly in 2015 is not the same as one made knowingly in 2026 with your signature on it, and he says courts care enormously about that difference.
Three things to do. Get your complete company file from whoever administers it while relations are still friendly, and expect to find that much of it does not exist. Bring the accounts and tax filings up to date, because unfiled accounts are the most likely trigger of an official letter and are entirely fixable. Then, over months rather than days, move to a structure that does not depend on strangers lending you their names.
The lawful route existed the whole time
This is the part that stings. You can own the house itself outright, registered in your own name, separately from the land under it. You can hold a 30-year lease of the land recorded on the title deed, which survives the landowner selling or dying. There are other registered rights, including one that can run for your lifetime.
Lanta is not a condominium island, so for most people here the realistic package is a lease plus the house in your own name.
Registering a 30-year lease costs around 1 per cent of the total rent over the term. Unwinding a company structure costs more, because the company has to sell the land at a real price: roughly 2 per cent transfer fee, plus 3.3 per cent business tax if the company sells within five years, plus fees. He estimates a few hundred thousand baht for a typical villa.
The restriction is time, and he is direct about it. A lease is 30 years. Promises of "30 plus 30 plus 30" bind the person who signed them, not the land. "Anyone selling you a guaranteed 90 years is selling a promise stapled to a hope."
His conclusion after twenty years:
"The foreigners in trouble today are not in trouble because Thai law gave them no options. They are in trouble because the lawful option said tenant for 30 years, and someone on a beach said owner forever, and the second sentence was more pleasant to hear."
