60 Nominee Cases on Koh Samui: Thailand's 1.2 Billion Baht Property Crackdown Explained

Eighty eight suspects, fifty nine companies, and properties worth a combined 1.2 billion baht. Koh Samui, the island that has drawn foreign buyers to villas overlooking the Gulf of Thailand for decades, has become the epicenter of the largest nominee ownership crackdown in the history of Surat Thani province.

This is not an abstract tightening of rules. It is a concrete operation that has resulted in 60 criminal cases. For international investors weighing land or villa purchases on Thailand's southern islands, the signal is unambiguous: the era of quasi-legal workarounds is closing.

The nominee structure worked in a simple way. A foreigner would set up a Thai company in which a controlling stake was formally held by Thai nationals. The company would then buy land, while the actual beneficiary, the foreign investor, managed the asset through private side agreements. Thailand's Land Code Act B.E. 2497 directly prohibits foreigners from owning land, and the Foreign Business Act B.E. 2542 criminalizes the use of proxies to circumvent that rule.

According to Bangkok Post, the operation reviewed 12,906 registered companies on Koh Samui. Of these, 8,254 had foreign shareholders, and 875 showed signs of using Thai nominees, a scale that shows this was a systematic audit rather than a handful of isolated raids.

Quick Answer

• Thai authorities have opened 60 criminal cases over illegal property ownership through nominee structures on Koh Samui

• 88 suspects and 59 companies are under investigation

• The total value of the flagged properties is approximately 1.2 billion baht (around 33 million USD)

• The crackdown targets the resort segment: villas, sea view plots, and hotel style properties

• Foreigners cannot directly own land in Thailand; legal routes include long term leasehold and condominium purchases within the 49% foreign ownership quota

• Penalties for nominee ownership include fines and imprisonment for everyone involved, including the Thai nominee shareholders

Key Facts

• Scale of the operation. Bangkok Post reports that the sweep covered 12,906 registered Koh Samui companies, of which 8,254 had foreign shareholders and 875 displayed signs of using Thai nominees. The island has roughly 6,000 registered villas, a significant share of which are held by foreigners through Thai legal entities.

• Legal basis. Those implicated face charges under the Foreign Business Act B.E. 2542 (using proxies to run business activities restricted to Thai nationals) and the Land Code Act B.E. 2497 (illegal land ownership). Penalties include fines of up to 1 million baht and/or imprisonment of up to 3 years.

• A widening enforcement trend. Since 2023, Thailand's Department of Special Investigation (DSI) has carried out similar raids in Phuket, Pattaya, and Chiang Mai. Koh Samui is the fourth major target, confirming this is a coordinated regional campaign rather than a one off action.

• Related raids nearby. According to The Nation Thailand, DSI and the Department of Business Development also raided five nominee networks across Koh Samui and Koh Phangan, uncovering multi billion baht schemes, including one law firm accused of registering more than 100 shell companies and using its own staff as proxy shareholders, with links to Chinese and Israeli interests.

• Economic backdrop. Koh Samui is in the middle of an investment boom. Market estimates put the average price of a three bedroom villa on the island's northern coast rising from 8-12 million baht in 2021 to 15-22 million baht in 2025, a surge that has drawn in a new wave of buyers willing to accept risky legal structures.

• Consequences for owners. Flagged properties are subject to forced sale. If an owner fails to divest within the set timeframe, the court can transfer the land to the state, with no compensation provided.

• Regional pattern. Cambodia, Vietnam, and Indonesia (Bali) are also tightening controls on nominee ownership, placing the Thai campaign within a broader Southeast Asian trend.

FAQ

Can foreigners legally buy land in Thailand in 2026?

No. Thailand's Land Code prohibits direct land ownership by foreign nationals. Exceptions are extremely rare and require special approval from the Ministry of Interior, tied to investments of at least 40 million baht in approved projects. In practice, these exceptions are almost never applied.

What is a nominee structure and why is it illegal?

A nominee structure involves registering a Thai company with formal Thai shareholders who contribute no real capital and make no management decisions. Their role is simply to create the appearance of Thai control. Courts and the DSI now identify such structures through indirect markers: no genuine business activity, disproportionate powers of attorney, and a company whose sole asset is a piece of land.

What legal ownership options are available to foreigners?

There are two main routes: buying a condominium unit within the foreign ownership quota (49% of a building's total area) with full freehold title, and long term leasehold on land or a villa for up to 30 years, with the possibility of renewal. Leasehold does not grant land ownership but is legally protected and registered at the land office.

Does the crackdown affect condominium owners?

No. The campaign targets illegal land ownership through shell companies exclusively. Foreign owners of condominium units purchased within the 49% quota are operating on fully legal ground.

What happens to properties caught up in the investigation?

A court can order the owner to sell the asset within a set period, typically 180 days to 1 year. If the sale does not go through, the land reverts to the state. Those involved also face criminal penalties in parallel.

Is this limited to Koh Samui?

No. Similar investigations have already taken place in Phuket and Pattaya, and the DSI has announced plans to extend checks to Krabi, Hua Hin, and Chiang Rai. Koh Samui was singled out due to its unusually high concentration of suspicious companies per square kilometer.

How can I protect my investment if I am already using a nominee structure?

Consult a licensed Thai lawyer immediately. Options include restructuring into a legal leasehold, selling the asset to a Thai buyer, or converting it into a condominium arrangement where the property allows it. Delay increases the risk of drawing DSI attention.

Will the crackdown affect Koh Samui property prices?

In the short term, forced sellers entering the market could soften prices in the villa segment. Over the medium term, market observers expect a cleaner ownership structure to boost confidence in the island and attract institutional investors.

Is Koh Samui still worth considering for investment right now?

Yes, but only through legal structures. The island remains one of the most sought after resort destinations in Southeast Asia. Condominiums held in freehold, long term leasehold on villas, and professional rental management all operate without legal risk and can deliver yields of 5-8% annually in resort areas.

The lesson of 2026 is straightforward: cheap legal shortcuts end up costing the most.
