The 2026 Samui Nominee Crackdown — A Straight-Talking Guide for Villa Owners

The short version. Thailand's laws restricting foreign land ownership have not changed. What changed in 2026 is enforcement — an AI-driven screening system at the Department of Business Development, new source-of-funds requirements for Thai shareholders, in-person verification for company amendments, and a published list of 16 high-risk provinces that includes Surat Thani. Owners who hold their villas through legitimate, substance-backed structures have nothing structural to fear. Owners with nominee-based Thai company structures now have a clear window to fix things on their own terms, before a regulatory flag arrives in the post.

Important note before we start. Mr Property Siam is a villa management company. We are not lawyers, we do not sell real estate, and nothing in this article is legal advice. If any of this applies to your situation, please speak to a licensed Thai corporate or property lawyer. We list several trusted firms at the end.

What the crackdown actually is

Thailand has restricted foreign land ownership since the Land Code Act of 1954, and it has criminalised the use of Thai "nominees" to disguise foreign ownership since the Foreign Business Act of 1999. None of that is new.

What is new is enforcement. Starting in late 2025, Thailand's Department of Business Development (DBD) began operating an AI-driven screening platform called IBAS — the Intelligence Business Analytic System. IBAS cross-references company registry data against Revenue Department and Land Department records in real time, looking for one specific pattern: financial implausibility.

The classic example: a Thai national with a modest declared income listed as majority shareholder in a company that holds a multi-million-baht villa. The AI flags it. Investigators follow up.

What is genuinely new in 2026

Six things have changed, and every villa owner should understand them:

1. AI screening is live and continuous (DBD Order 2/2568 in force since 1 January 2026). It runs in the background. Nobody has to complain for a company to get flagged.
2. Source-of-funds evidence is now mandatory at company registration. Thai shareholders must produce 3 months of bank statements showing the money they used for their shares came from their own account.
3. Amendments trigger the same checks (DBD Order 1/2569, effective 1 April 2026). If your existing company changes directors, transfers shares, or increases capital, the whole structure gets re-examined.
4. In-person verification is required. Thai shareholders and directors must physically appear at the DBD office for certain amendments. Powers of attorney no longer suffice.
5. The "actual control" test. Registrars now look beyond the shareholder register to who really controls the company — voting rights, veto arrangements, financing, management agreements. Foreign control can be found even where foreign shareholding sits under 50%.
6. Surat Thani is on the target list. On 16 July 2026 the DBD named 16 high-risk provinces for enhanced bank-statement checks. Surat Thani is one of them. From 1 August 2026, Thai shareholders and directors in flagged companies must submit bank statements on request.

What is NOT changing

This part matters just as much:

• The law itself has not changed. These are enforcement rules under the existing FBA and Land Code, not new statutes.
• Condominium freehold within the 49% foreign quota is unaffected. If you own a condo unit in your own name inside the building's foreign quota, this crackdown does not describe you.
• Legitimate long-term leases are unaffected. A properly registered 30-year lease remains a recognised route.
• Thai spouse ownership remains lawful provided the sin suan tua (separate personal property) declaration is truthful and the funds are the Thai spouse's own.
• Property management services are not the target. The crackdown is aimed at Thai companies used to hold land for foreigners, not companies that manage villas owned by third parties.

Who is at risk — and who is not

Below is a simplified read of who tends to sit where. This is not legal advice; every situation needs a real review.

The "substance test" — what IBAS is really looking for

Whatever your structure, the modern test is not what the paperwork says. It is what actually happened. A lawful Thai company has to be able to answer four questions with real evidence:

1. Who paid? Every shareholder must show they funded their own shares from their own money.
2. Who controls? Voting rights, director appointments, veto arrangements — do they match the paper structure?
3. Who benefits? Are dividends genuinely declared and paid to the Thai shareholders?
4. Is it plausible? Does the Thai shareholder's income, wealth and background make their stake believable?

If the honest answer to any of these is "no, this was arranged for the foreigner's benefit," the structure fails the modern test even if the shareholder register looks Thai on paper.

Penalties — what is actually on the table

Under FBA Section 36, both the Thai nominee and the foreign principal face:

• Up to 3 years imprisonment
• Fines of THB 100,000 to 1,000,000
• Daily fines of THB 10,000 to 50,000 while the arrangement continues
• Company dissolution and asset seizure
• Potential visa blacklisting and deportation for the foreigner

Under the Land Code, land found to be held unlawfully must be sold within 180 days to 1 year under Section 94. Proceeds go to the (foreign) owner, but during that window the villa is effectively frozen — no refinancing, no sale on your terms, no clean chain of title. Important: liability is shared. The Thai partner is exposed alongside the foreigner. Anyone who "knowingly assists" — lawyers, accountants, agents — can also be caught under Section 36.

What we recommend villa owners do right now

Not legal advice — practical, common-sense steps we suggest to every owner we speak to:

1. Locate your paperwork. Chanote or condo unit title. Company affidavit and shareholder list (บอจ.5) if held through a company. Lease agreement and its registration record if leasehold. Sin suan tua declaration if held by a Thai spouse.
2. Trace the money. Do you have — or can you reconstruct — evidence of the source of funds for shares and for the property purchase? Bank statements, transfer records, gift documentation from family.
3. Confirm dividends and governance. If you hold through a Thai company, when were dividends last declared? Are director resolutions on file? Are Thai shareholders genuinely part of decisions?
4. Ask honestly whether the substance test passes. If it does not, this is the moment to speak to a Thai lawyer about regularising — BOI route, lease conversion, sale or a genuine restructuring with real Thai investors.
5. Do not hide. DBD guidance is clear that voluntary compliance is treated far more favourably than being caught by an IBAS flag.

Where MPS fits into this

We manage villas. We do not hold your land, and we do not sell real estate. That means MPS itself is structurally outside the target profile of this crackdown.

But we do care whether the villas we manage are held lawfully, both because it protects your investment and because it protects us as your operator. In 2026 we have strengthened our onboarding due diligence and updated our management agreement to make ownership representations explicit. Read the companion piece: How MPS Screens the Villas We Manage — Our 2026 Ownership Due Diligence.

If you are still choosing an ownership structure, or reconsidering an existing one, our other companion piece walks through the legal options: Legal Ways to Own Villa Property in Thailand — A 2026 Owner's Guide.

Thai lawyers we suggest for a paid review

If you would like an introduction, or you want us to sit in on a call as your operator, we are happy to help.

Thailand's 2026 enforcement wave is not the end of foreign villa investment on Samui. It is a serious tightening of the rules that have always been the rules, applied through new tools — AI screening, in-person verification, source-of-funds checks. Owners on the right side of the substance test have nothing structural to fear. Owners who are not now have a clear window to fix it, on their own terms, before a flag arrives in the post.
