Introduction
Thailand remains an attractive destination for foreign investors seeking access to Southeast Asian markets. However, foreign investment is subject to restrictions under Thai law, particularly the Foreign Business Act B.E. 2542 (1999) (FBA). Some investors attempt to overcome these restrictions by registering a Thai limited company with Thai nationals listed as majority shareholders, even though the foreign investor supplies the capital, controls the business, and receives the economic benefits.
This arrangement may constitute illegal nominee shareholding. It is not made lawful simply because the company has been registered with the Department of Business Development (DBD), the Thai shareholders have signed the incorporation documents, or the company has operated for several years without an inspection.
Thailand has also strengthened its scrutiny of potentially unlawful ownership structures. In 2026, the DBD introduced additional registration and documentation requirements concerning foreign participation and the source of investment funds. Foreign investors should therefore assess both the legality of their ownership structure and their ability to demonstrate that each shareholder's investment is genuine.
1. What Is a Nominee Shareholder?
A nominee shareholder is a person who holds shares on behalf of another person rather than as a genuine investor in their own right. In the context of foreign investment in Thailand, the term commonly refers to a Thai national who is listed as a shareholder to make a company appear to satisfy Thai ownership requirements, while the foreign investor is the actual beneficial owner or exercises the control that the structure is intended to conceal.
For example, a company may be registered with 51% of its shares held by Thai nationals and 49% held by a foreign investor. On paper, the company appears to be Thai-majority-owned. However, if the Thai shareholders have not genuinely invested their own funds, are required to follow the foreign investor's instructions, or hold their shares under an arrangement designed to circumvent foreign business restrictions, the structure may attract investigation.
The distinction is between genuine Thai investment and shareholding used as a device to conceal foreign participation.
Not every Thai shareholder who is less involved in daily management is a nominee. Nor is every company with foreign shareholders unlawful. The relevant question is whether the ownership and investment arrangements are genuine and whether the structure is being used to circumvent restrictions imposed by Thai law.
2. Why Does Thai Law Restrict Nominee Arrangements?
The Foreign Business Act regulates the participation of foreigners in specified categories of business. Its application depends on matters including the definition of a foreigner under the Act, the nature of the business, the company's ownership and control structure, and any applicable exemption or authorisation.
The Act's annexed lists identify categories of business subject to different levels of restriction. Depending on the category, foreign participation may be prohibited, subject to specific conditions, or permitted only after obtaining the required authorisation.
A company cannot lawfully avoid these restrictions merely by placing Thai names on its shareholder register. Section 36 of the FBA specifically addresses Thai nationals or Thai juristic persons who assist in or participate in restricted foreign business operations, operate a business jointly with a foreigner while presenting it as their own, or act as nominees to enable a foreigner to circumvent the Act. The provision also addresses a foreigner who allows such nominee conduct to occur.
Other legal regimes may apply depending on the circumstances. For example, a nominee arrangement involving land ownership can raise separate issues under the Land Code. The legal analysis must therefore consider the actual business activity and assets involved, rather than examining the shareholder register alone.
3. Common Warning Signs of Nominee Shareholding
Authorities may examine the substance of an ownership arrangement rather than relying exclusively on registered documents. Indicators that may prompt further scrutiny include the following.
Thai shareholders cannot demonstrate the source of their investment funds. If a shareholder is recorded as having invested substantial capital but cannot explain the source of the money or produce supporting financial records, the genuineness of the investment may be questioned.
The foreign investor provides the Thai shareholders' capital. A foreign investor financing Thai shareholders' share subscriptions without a genuine, properly documented commercial arrangement may create concerns about whether the Thai shareholders are independent investors. The source, purpose, terms, and economic substance of any funding arrangement matter.
Thai shareholders have no meaningful economic interest. An arrangement under which Thai shareholders are guaranteed a return regardless of business performance, are required to transfer all economic benefits to the foreign investor, or bear no genuine investment risk may indicate that their registered ownership does not reflect the actual arrangement.
Control is inconsistent with the documented ownership structure. Authorities may examine who makes business decisions, controls company bank accounts, directs employees, negotiates contracts, and receives the company's economic benefits. Foreign management involvement is not automatically unlawful, but the surrounding facts may be relevant to determining whether an ownership structure is genuine.
Shareholders sign documents without understanding their investment. Shareholders who cannot explain the company's activities, their own financial contributions, or their rights and obligations may attract questions about whether they are genuine participants.
The company provides inconsistent information. Differences between corporate documents, bank records, accounting records, shareholder explanations, and the actual operation of the business may increase regulatory risk.
No single indicator necessarily proves an offence. The evidence must be assessed in context, including the source of capital, the contractual arrangements, actual conduct, and the legal restrictions applicable to the business.
4. What Are the Penalties Under the Foreign Business Act?
Section 36 of the FBA establishes criminal penalties for conduct within its scope. A Thai national or Thai juristic person acting as a nominee, or engaging in the other prohibited conduct specified by the section, may face imprisonment for up to three years, a fine of THB 100,000 to THB 1,000,000, or both.
The provision also covers a foreigner who allows the prohibited nominee conduct to be committed. Accordingly, foreign investors should not assume that criminal exposure is limited to the Thai shareholders whose names appear in the company's records.
The court is also required under Section 36 to order the cessation of the relevant assistance, joint business operation, shareholding, or partnership, as applicable. If a person violates the court's order, an additional fine of THB 10,000 to THB 50,000 per day may apply for the period of non-compliance.
Where a foreigner independently operates a business in violation of Sections 6, 7, or 8 of the FBA, Section 37 provides for imprisonment for up to three years, a fine of THB 100,000 to THB 1,000,000, or both, together with a court order to cease the prohibited business operation or other relevant activity. Daily fines may apply if the court's order is violated.
The precise offence and penalty depend on the facts and the applicable statutory provision. These provisions should not be treated as a single automatic penalty applying identically to every case involving foreign shareholding.
5. Can Directors and the Company Also Be Exposed?
Yes. Nominee-related investigations can extend beyond the individuals listed as shareholders.
Section 41 of the FBA provides that where a juristic person commits an offence under the specified provisions, including Sections 36 and 37, its directors, partners, or persons authorised to represent it may also face imprisonment for up to three years, a fine of THB 100,000 to THB 1,000,000, or both, where they connive in the offence or fail to take reasonable action to prevent it.
This does not mean every director is automatically criminally liable because a company is investigated. The statutory requirements and the person's involvement must be considered.
A company may also face operational consequences if it is ordered to cease an unlawful business activity or alter an unlawful shareholding arrangement. Correcting the shareholder register alone may not resolve every issue if the underlying business continues to operate without the necessary legal authorisation.
Foreign investors should also consider associated risks involving contracts, financing arrangements, property, licensing, tax compliance, and ongoing business operations. The effect on any particular contract or asset depends on the applicable law and the facts; it should not be assumed that every company contract automatically becomes void because nominee shareholding is suspected.
6. Thailand's Enhanced Scrutiny of Foreign-Linked Companies in 2026
Regulatory scrutiny has become more focused on whether registered Thai shareholders have genuinely invested their own funds.
The DBD's 2025 annual report described investigations into suspected nominee arrangements across sectors including tourism, land trading and real estate, e-commerce, logistics, warehousing, hotels and resorts, agriculture-related packing houses, and general construction. It reported that requests for clarification were issued to directors and shareholders of 777 entities as part of its inspection activity. These figures illustrate the scope of regulatory screening; they do not mean that all entities contacted were found to have committed offences.
In 2026, the DBD introduced further measures affecting company registrations involving foreign participation. Central Partnership and Company Registrar Order No. 2/2569, effective from 1 August 2026, introduced additional documentary requirements for certain partnerships and limited companies involving foreign shareholders or foreign authorised signatories. It followed earlier measures concerning the verification of genuine investment and source-of-funds documentation.
The applicable requirements depend on the type of registration and the company's circumstances. Companies should check the current requirements with the DBD or qualified Thai legal counsel before filing an incorporation or amendment application. They should not assume that the documents accepted at an earlier stage will necessarily be sufficient for a later registration.
In practical terms, foreign-linked companies should be prepared to explain how Thai shareholders funded their share subscriptions and to support those explanations with appropriate records. A statement confirming genuine investment is not a substitute for genuine investment itself.
7. What Evidence Should Genuine Thai Shareholders Keep?
A company with genuine Thai investors should maintain a clear and consistent record of its capital structure. The documents needed will depend on the facts and any current DBD filing requirements, but relevant records may include:
- Bank statements showing the source and transfer of funds used to pay for shares.
- Evidence of the Thai shareholder's income, savings, asset sales, or other lawful funding source, where relevant.
- Share subscription and payment records, together with the company's accounting entries.
- Shareholder registers, share certificates, and corporate resolutions consistent with the actual ownership arrangements.
- Agreements documenting genuine loans or other funding arrangements, where applicable.
- Records demonstrating that shareholder rights, economic interests, and obligations reflect the actual commercial relationship.
The existence of a bank transfer alone does not necessarily establish genuine investment. Authorities may consider where the money originated, whether it was returned or redirected, whether the shareholder bears genuine economic risk, and whether the records reflect the actual transaction.
Companies should preserve accurate original records and provide truthful explanations when responding to official enquiries. Fabricating records, arranging retrospective paperwork to disguise the source of funds, or providing false information can create additional legal exposure.
8. Lawful Alternatives for Foreign Investors
Foreign investors who wish to establish or expand a business in Thailand should assess lawful ownership and authorisation options before committing capital.
Establish a genuinely Thai-majority-owned company. This structure may be appropriate where Thai shareholders are real investors who contribute capital, hold genuine economic interests, and exercise their rights as shareholders. It should not be used as a façade to conceal foreign ownership or circumvent applicable restrictions.
Apply for a Foreign Business License (FBL). Where the proposed activity falls within a restricted category and licensing is available, an FBL may provide a lawful route to operating the business. Eligibility, approval criteria, and supporting documents depend on the business and the applicable list.
Assess eligibility for a Foreign Business Certificate or statutory exemption. Certain businesses may qualify for a certificate or exemption under an applicable law, treaty, investment promotion framework, or other legal instrument. Eligibility must be assessed against the specific activity and conditions; no general exemption should be assumed.
Consider investment promotion or other permitted structures. Depending on the project, the Board of Investment (BOI) or another applicable regime may provide benefits or authorisations. Promotion is not automatic, and the scope of permitted activities and conditions must be checked carefully.
Separate restricted and unrestricted activities where legally appropriate. A group may sometimes organise different business activities into separate entities, provided each entity's activities, ownership, licensing, transactions, and actual operations comply with Thai law. Separating activities on paper will not cure an arrangement that is unlawful in substance.
The appropriate route depends on the proposed business, ownership, capital, management, and long-term commercial objectives. A structure that works for one industry may be unsuitable for another.
9. What Should a Company Do If It Suspects a Nominee Problem?
If an existing company discovers that its registered ownership does not reflect the genuine investment arrangement, it should obtain a legal review before making further transfers or amendments.
The review should identify the business activities subject to the FBA, establish who funded each share subscription, examine shareholder and financing agreements, assess actual control and economic benefits, and determine whether any required licence, certificate, or exemption is available.
The company should preserve relevant records and respond to official enquiries accurately and within the applicable deadlines. It should not destroy documents, create misleading evidence, or transfer shares solely to conceal the existing arrangement.
Depending on the findings, the company may need to restructure its ownership, obtain the appropriate authorisation, discontinue a restricted activity, or take other corrective steps. Any restructuring must itself comply with applicable company, foreign business, land, tax, and other relevant laws.
Where an investigation has already begun, or a company has received a formal request from the DBD or another authority, legal advice should be obtained promptly. The consequences of an alleged nominee arrangement depend on the evidence and the statutory provisions involved, so a generic corrective procedure may not be appropriate for every case.
Conclusion
Nominee shareholding is not a lawful shortcut for avoiding foreign business restrictions in Thailand. Section 36 of the Foreign Business Act provides for significant criminal penalties and court-ordered cessation of prohibited arrangements, while other provisions may apply where a foreigner operates a restricted business without the necessary authorisation.
With enhanced DBD scrutiny and additional registration requirements introduced in 2026, foreign investors should be able to demonstrate that Thai shareholders have genuinely invested their funds and that the company's ownership structure reflects its actual commercial arrangements.
The safest approach is to determine the applicable restrictions before incorporation or investment, document genuine capital contributions, and select a lawful ownership or authorisation structure suited to the proposed business.
