The Nominee Crackdown: What Foreign-Owned Client Structures Look Like When Regulators Follow the Money

For a boutique law or accounting firm, the foreign founder is one of the most valuable clients in the market, as the earlier articles in this series set out. Foreign capital is arriving, BOI incentives are attractive, and the founders are often grateful for a firm that can handle company formation, tax, and compliance in one place. That opportunity has a shadow, and 2026 made the shadow longer: the long-standing prohibition on nominee shareholding is now being enforced with a rigour that firms have not seen before.

This article is not a guide to structuring around the rules. It is a guide to recognising the risk, understanding how the approach to enforcement has changed, and making sure a firm’s own conduct and records protect it. The tone is deliberate. A nominee arrangement is a risk to avoid, not a service to optimise.

The Rule Is Not New; the Enforcement Is

The Foreign Business Act restricts foreign participation in many business activities. To get around those limits, some structures have used Thai individuals as nominal shareholders who hold shares on behalf of foreign owners, with the real control and funding sitting abroad. Section 36 of the Act already prohibits Thai nationals from assisting foreigners in this way.

For years the practice was widespread, and enforcement was inconsistent. That is the change. Reporting on 2026 describes a coordinated tightening, led by the Department of Business Development and complemented by land authorities, that treats nominee arrangements as an active enforcement priority rather than a background compliance issue.

What Has Reportedly Changed

The details are administrative and they have moved quickly, so a firm should confirm the current position directly with the Department of Business Development and the Royal Gazette rather than rely on any summary, including this one.

According to a law-firm summary updated in October 2026, a Central Registrar order effective 1 August 2026 now governs the process. It reportedly replaced earlier orders that had required in-person verification of Thai shareholders during a window from April to July 2026. Under the current order, the registrar expects documents that trace the money: bank statements from each Thai shareholder, statements for the account that received the funds, and a signed letter explaining the investment and where the money came from. A further confirmation letter is reportedly required when certain amendments are filed, such as adding a foreign authorised signatory to a company whose signatories were previously all Thai.

The substance matters more than the paperwork. A registrar who compares a shareholder’s bank statements with the declared capital is asking a simple question: did this person actually pay for these shares with their own money? If the answer is no, the structure looks like what the Act prohibits.

Alongside these company-registration measures, reports describe administrative circulars from land authorities that allow officers to question buyers of land in certain circumstances. These circulars are said to create no new law, but they extend the same scrutiny into property transactions.

The Idea of Actual Control

Some commentary frames the reform direction as a move from form to substance: from asking who holds the shares on paper to asking who actually controls the company. Several sources describe a proposed shift towards an actual control test in the Foreign Business Act itself, and sources disagree on whether any statutory amendment has been enacted or remains pending.

The prudent reading is that the concept is already visible in practice, even if the statutory definition has not changed. When a registrar traces funds and checks who is authorised to sign, it is effectively testing whether Thai shareholders are genuine investors or placeholders. A firm should assume that a structure which only satisfies the 50% shareholding rule on paper may not survive that scrutiny, and should not wait for a formal definition before taking the risk seriously.

Because the legislative position is contested, a firm should avoid telling clients that the law has definitely changed in one direction or another. The accurate message is that enforcement and verification have tightened, that further reform has been discussed, and that the safest assumption is stricter treatment, not looser.

Why Advisers Are Exposed

The most important point for a boutique firm is that liability is not limited to the nominee and the foreign owner. Reported penalties under Section 36 include imprisonment and substantial fines, and the summaries state that both the Thai nominee and the foreign party who procured the arrangement can be prosecuted. Related provisions on false statements to officials and forged documents add further exposure where documents have been misrepresented.

Sources also report that facilitators have been caught. One summary cites a case in which lawyers and accountants were convicted, and another states that investigators obtained old records from accounting firms for a company dissolved years earlier. The reported enforcement statistics come from press coverage and are not verified, but the direction is clear enough to act on: an adviser who sets up, supports, or knowingly maintains a nominee structure shares the risk, and a firm’s historic files can become evidence.

This is not a reason to avoid foreign clients. It is a reason to be disciplined about which structures the firm will and will not take on.

What a Boutique Firm Should Do

The protective measures are practical and mostly about records and judgment.

Know the real ownership. For every foreign-owned client entity, the firm should be able to say who funds the company, who holds which rights, who actually makes decisions, and whether the Thai shareholders are genuine investors with their own resources. If the honest answer to any of those questions is uncomfortable, that is the signal to stop and advise differently.

Decline structures that depend on a placeholder. Where a client’s plan relies on a Thai shareholder who contributes nothing and controls nothing, the firm should not set it up and should explain why. There are lawful routes to foreign participation, including BOI promotion and structures permitted under the Act, and a firm that can explain them is more useful than one that quietly accepts the risk.

Document the due diligence. A dated record of what the firm asked, what it was told, and what it decided is the firm’s own protection. If a structure is later questioned, the file should show that the firm applied judgment, not that it processed instructions.

Review existing clients. Joint ventures and arrangements built on preference shares or sole-director structures may attract attention. If the pending reform is enacted without a transition framework, some arrangements could be reclassified. A review of the existing portfolio, led by the firm rather than prompted by the regulator, is prudent.

Take filing sequencing seriously. Changes such as adding a foreign signing director or altering shareholdings can trigger additional requirements. A firm that checks whether a proposed amendment falls within them before filing avoids delay and avoids creating a record that looks like concealment.

The Conversation With the Client

Founders sometimes arrive having been told by others that a nominee arrangement is routine. The firm’s role is to explain, calmly and without alarm, that the environment has changed and that the consequences fall on the founder as well as the Thai nominee. Many founders respond well to being told clearly, particularly when the firm can offer a lawful alternative.

That conversation is itself a differentiator. A founder who has been steered away from a risky structure by an adviser who understood the exposure will remember it. One who discovers the problem after an inquiry will remember that too.

FirmFlow and the Defensible Record

A defensible ownership structure depends on a record: who funds the company, who holds which rights, who actually decides. FirmFlow keeps a client’s incorporation documents, shareholder records, and the firm’s own due diligence notes in one matter file, so the firm can show its reasoning if a structure is ever questioned.

The foreign-founder opportunity remains real, and the firms best placed to serve it are those that can say what they will not do as clearly as what they will. In a period when regulators are following the money, a firm whose files show careful, documented judgment is protecting its clients and itself.
