Thailand Nominee Business Crackdown: Koh Samui Case Explained

A recent investigation on Koh Samui has placed Thai nominee shareholder arrangements and foreign business ownership back under scrutiny.

Surat Thani Immigration Police are investigating a French businessman suspected of using Thai nationals as nominee shareholders in companies connected to land and accommodation businesses on Koh Samui.

Authorities also identified an allegedly unlicensed 12-room accommodation business and are examining possible links to a cannabis investment scheme involving more than THB 26 million. Possible money laundering offences are also under investigation.

While the allegations remain subject to further investigation and legal proceedings, the case highlights an important compliance issue for foreign investors and Thai business partners:

A company may appear Thai-owned on paper, but regulators can look beyond the shareholder register to determine who actually funds, controls and benefits from the business.

What Did Authorities Find in the Koh Samui Investigation?

According to Khaosod English, investigators reviewed companies linked to land ownership and accommodation businesses in Lipa Noi, Koh Samui.

Authorities reportedly identified several issues that warranted closer scrutiny, including:

Thai shareholders holding a combined 60% interest despite allegedly lacking the financial capacity to make the investment
a Thai shareholder allegedly stating that his name was used as a director while he exercised no real financial authority
corporate payments exceeding THB 7.7 million to the French businessman personally
payments of more than THB 1.5 million to his son
a company reportedly recording continued losses while primarily holding land
operation of a 12-room accommodation property without a hotel licence
possible links to an alleged cannabis investment scheme involving more than THB 26.4 million

Authorities are continuing to examine the ownership, funding and control of the businesses involved.

What Is a Nominee Shareholder in Thailand?

A nominee arrangement generally refers to a structure in which a Thai individual holds shares on behalf of a foreigner so that a company appears to satisfy Thai ownership requirements, while the foreign party remains the true investor or controller.

This is important because Thailand’s Foreign Business Act B.E. 2542 (1999) restricts foreign participation in a number of business activities unless the relevant permission or exemption has been obtained.

Having Thai shareholders is not automatically illegal.

The compliance concern arises when Thai shareholders are not genuine investors and are instead being used to conceal the real ownership or control of the business.

Why the 49% / 51% Structure Is Not Enough

One of the most important compliance lessons is that shareholding percentages alone do not determine whether a structure is lawful.

A company may show:

51% Thai ownership
49% foreign ownership

but regulators may still investigate who actually controls the business.

Authorities may look at:

who provided the original investment capital
whether Thai shareholders actually paid for their shares
who controls company bank accounts
who makes business decisions
who receives profits and economic benefits
whether Thai directors exercise real authority
whether side agreements effectively transfer control to a foreign investor

The key issue is whether the company’s legal structure reflects its commercial reality.

Why Land Ownership Is Particularly Sensitive

The Koh Samui investigation is especially notable because the companies under review were connected with land ownership.

Foreign ownership of land in Thailand is heavily restricted.

For this reason, authorities pay particular attention to structures in which Thai-registered companies acquire land while there are indications that the company may actually be funded or controlled by foreign nationals.

For property investors, this means that company registration should not be treated simply as a way to satisfy a numerical Thai shareholding requirement.

The underlying ownership and control structure must also be genuine.

Hotel Licensing Creates a Separate Compliance Risk

The investigation also highlights another important issue:

Corporate ownership compliance does not replace sector-specific licensing requirements.

Authorities reportedly found that the Koh Samui property contained 12 rooms and a restaurant and was advertised for short-term stays through online booking platforms, but no hotel licence was registered for the property.

This illustrates how one business can face multiple regulatory obligations at the same time.

Depending on the activity, businesses may need to consider:

Foreign Business Act restrictions
land ownership rules
company law
hotel and accommodation licensing
immigration requirements
employment and work permit rules
tax obligations
local regulatory approvals

Compliance in one area does not automatically mean the entire business is compliant.

Why Source of Funds Matters

Another significant aspect of the investigation is the attention being paid to financial flows.

Investigators reportedly identified transfers from company accounts to the businessman and his son and are examining whether assets or funds connected with alleged unlawful activity may have been used for investment.

This moves the issue beyond corporate ownership and into financial crime compliance.

Investigators may ask:

Where did the investment capital come from?
Who ultimately controlled the funds?
Why were funds transferred between individuals and companies?
Were those transactions supported by legitimate business reasons?
Were any assets acquired using proceeds connected to criminal activity?

For businesses, this reinforces the importance of proper source-of-funds checks, bookkeeping and transaction documentation.

The Wider Thailand Nominee Crackdown

The Koh Samui case should not be viewed in isolation.

Thai authorities have increasingly focused on suspected nominee structures, particularly in sectors where foreign investment is common.

Areas of regulatory attention can include:

property and land
tourism and accommodation
restaurants
construction
retail
services
other businesses restricted under the Foreign Business Act

Regulators are also increasingly able to compare company records with financial, ownership and other government data.

This means businesses should not assume that corporate registration documents will be reviewed in isolation.

What Should Foreign Investors Check?

Foreign entrepreneurs and investors operating in Thailand should regularly review their ownership and governance structures.

Are Thai Shareholders Genuine Investors?

Thai shareholders should have a legitimate economic interest in the business rather than simply lending their names to satisfy ownership requirements.

Can Shareholders Explain the Source of Their Investment?

If a shareholder owns a significant percentage of a company, there should be a credible and documented source for that investment.

Who Actually Controls the Business?

Consider voting rights, board powers, banking authority, contractual arrangements and day-to-day decision-making.

Does the Business Require Foreign Business Permission?

Businesses should determine whether their activities fall within the Foreign Business Act and whether a Foreign Business Licence, certificate, BOI promotion or another exemption may be required.

Are All Required Licences in Place?

Businesses operating hotels, restaurants, tourism services or other regulated activities should ensure that the necessary licences and approvals have been obtained.

Are Financial Transactions Properly Documented?

Payments between a company, shareholders, directors and related parties should have a legitimate business purpose and supporting documentation.

Nominee Risk Is a Governance Issue

Nominee compliance is not simply a question of whose name appears on a shareholder register.

It is fundamentally about substance over form.

Authorities may look at the relationship between:

shareholders
directors
investors
company assets
financial flows
decision-making authority

A Thai shareholder listed in corporate documents may not be enough to establish genuine Thai ownership if evidence suggests that:

the foreign investor supplied all of the capital
the Thai shareholder has no meaningful involvement
financial control remains with the foreign investor
profits primarily benefit the foreign investor
side agreements remove the Thai shareholder’s real ownership rights

For compliance teams, accountants, corporate service providers and professional advisers, nominee risk should therefore be treated as part of broader corporate governance, beneficial ownership and financial crime controls.

What the Koh Samui Case Means for Businesses

The investigation remains ongoing, and the allegations should not be treated as proven unless established through the relevant legal process.

However, the case provides a useful compliance warning.

Regulators are increasingly looking beyond corporate paperwork and asking:

Who provided the money?
Who controls the company?
Who owns the assets?
Who receives the benefits?
Does the structure reflect commercial reality?

For legitimate foreign investors, this does not mean foreign investment in Thailand is prohibited.

It means investment structures should be designed within the legal framework rather than around it.

As Thai authorities continue to scrutinise nominee arrangements, businesses should review ownership structures, shareholder funding, licences and financial records before those issues are raised during an investigation.

Transparent ownership is becoming an increasingly important part of doing business compliantly in Thailand.
