How do you keep control of your Thai company?

Key Takeaways

• Shareholding percentage, board composition, voting rights and signing authority are four separate levers. A minority shareholder can hold real control through the other three.
• Preference shares are permitted, and once issued their rights cannot be changed without the preference shareholders’ consent.
• Giving a foreign director signing authority is a genuine control mechanism. It also independently triggers DBD Order 2/2569’s evidence requirements, even in a company with no foreign shareholders at all.
• A structure built to hand a foreigner total control while a Thai holds the shares on paper is not a lighter version of any of this. It is a nominee arrangement, and after 1 August 2026 it is an evidenced one.

In Detail

Control is not one number

The fear behind this chapter is usually stated as a percentage: what happens if I only hold 49 percent. That framing treats shareholding as the whole of control, and it is not. A Thai limited company separates economic ownership from decision-making in the same way most company law does. Who holds shares, who sits on the board, who can vote on what, and who can sign on behalf of the company are four different questions, each answered by a different document or rule.

The Civil and Commercial Code’s own default for a shareholders’ meeting is a quorum of at least two shareholders or proxies representing at least one quarter of the registered capital.¹ That is a floor, not a ceiling. It tells you the minimum Thailand asks for a meeting to count. It says nothing about what your company’s own Articles of Association require for a particular decision, and that is where the real control questions get answered.

Preference shares

Thai limited companies can issue preference shares alongside ordinary shares, and once those preferential rights are attached they cannot later be altered without the consent of the preference shareholders. Ordinary shares cannot be converted into preference shares afterward.² In practice this means a Singapore company can hold a minority economic stake as preference shares carrying fixed rights, such as a dividend preference or a veto over specific decisions, and those rights survive a later disagreement with the Thai partner in a way an informal side letter does not.

Reserved matters, board seats and signing authority

Beyond the statutory quorum, Thai company law leaves the design of your control structure to you. A shareholders’ agreement and the Articles of Association are where a Singapore owner actually writes down which decisions need unanimous or supermajority sign-off, how many board seats each side gets, and who can appoint or remove a director. None of that is fixed by statute the way the 49 percent foreign ownership line is. It is negotiated, and it is only as good as the document it sits in and your ability to enforce that document, which is the subject of the next section.

Signing authority deserves its own line because it does two things at once. Giving your foreign director sole or joint authority to sign on the company’s behalf is a legitimate and common way to keep operational control without holding the majority of shares. It is also, independently of your shareholding split, one of the two conditions that triggers DBD Order 2/2569. The order applies where foreign shareholders hold less than 50 percent of registered capital, or where a wholly Thai-held company has a foreign director with sole or joint signing authority.³⁴⁵ Read that twice. A company that is 100 percent Thai-owned, with no foreign shareholder anywhere on the register, is still caught if it gives a foreign director the pen.

Once caught, the company must file an Explanation Statement and bank statements from each Thai shareholder covering the three months before their share subscription, showing a transfer that matches the capital contribution in amount and date, plus bank certification that the company received the payment.⁴⁵ This is the beneficial ownership question’s evidence regime again, reached by a different door. If your control structure gives a foreign director signing authority, price the paperwork in from the start rather than discovering it at registration.

What these mechanisms are worth in a fight

Say plainly what this chapter cannot promise. A reserved matter, a board seat or a signing restriction is a contractual and constitutional right. If your Thai partner breaches it, your remedy runs through a Thai court, and contracting with a Thai partner sets out what actually happens when a partnership dispute gets there, including how a foreign-language contract and a foreign judgment fare in that process. The short version for here is that a control mechanism whose only backstop is Thai litigation is worth exactly as much as your appetite, time and budget for that litigation, not more. Build the mechanism because it changes behaviour and gives you standing. Do not treat it as a guarantee that removes the need for a partner you actually trust.

Where legitimate control ends and nominee control begins

There is a version of everything above that is not a control structure at all. If the plan is for a Thai shareholder to hold shares on paper while a foreigner directs the company and keeps the economic benefit, with no genuine investment or commercial role on the Thai side, that is a nominee arrangement. It is a criminal offence, not a grey area or an aggressive structuring choice. Nominee shareholding is actively investigated and prosecuted by the Department of Business Development.⁶ The Thai nominee faces a fine of THB 100,000 to 1,000,000 and up to three years imprisonment under Section 36. The foreign principal who directed the arrangement faces a further THB 10,000 to 50,000 per day under Section 37, on top of that range. Neither penalty changed in 2026.⁷⁸

What changed is that it is now an evidenced offence rather than a suspected one. From 1 August 2026, the DBD Order 2/2569 bank-statement regime described above exists to test exactly this: whether the Thai shareholder’s money actually left their own account and arrived at the company. Someone who genuinely bought their shares produces this without difficulty. Someone whose stake was funded by their foreign partner cannot.

We are not telling you this to moralise. We are telling you because the line between a legitimate minority-control structure and a nominee arrangement is a real line, not a matter of degree, and a reader who tries to engineer around the ownership rules rather than through the mechanisms above is heading somewhere that now has a paper trail attached to it.

Treat any of the following as a warning, not a selling point.

Anyone who offers a “guaranteed control” structure. No structure guarantees control that survives a determined, badly-behaved partner without also surviving a Thai court. Anyone promising otherwise is either overselling ordinary mechanisms or describing something closer to a nominee arrangement than they are telling you.

Anyone who says the 49 percent split is a formality. It has never been a formality, and since 1 August 2026 it is specifically the condition that triggers additional evidence requirements on your Thai shareholders. A professional adviser who calls it a formality either has not read the current rules or is signalling that the arrangement they have in mind is not one you want your name on.

Anyone who arranges shareholders you have never met. A shareholder you did not choose, cannot describe, and have never spoken to is not a partner. They are a name on a register, and a name on a register is precisely what the DBD’s bank-statement requirement now exists to test.

What genuine due diligence looks like

The reassurance this chapter can actually offer is not a structure. It is a process. Before you sign anything, you can find out whether your prospective Thai partner has run a business before, whether they can explain in their own words what role they will play in yours, and whether the money for their shares is traceable to them rather than routed through you. You can ask to meet every name that will appear on the share register, not just the one who negotiates with you. You can have your own Thai-qualified lawyer review the Articles of Association and shareholders’ agreement before registration, not after a dispute starts. None of that is glamorous, and none of it is a shortcut. It is also the difference between a partner who passes the DBD’s new evidence regime without noticing it and one who cannot.

Before you rely on a control structure

• Have you separated shareholding, board seats, voting rights and signing authority into distinct, written terms, rather than assuming the share percentage covers all four?
• If you are relying on preference shares, does the document state the preferential rights clearly enough that a Thai court, not just your Singapore lawyer, could apply them?
• Will a foreign director hold sole or joint signing authority? If so, have you priced in DBD Order 2/2569’s bank-statement filing before you need it, not after?
• Have you met every person who will appear on the share register, and can each of them show the money for their shares is genuinely theirs?
• If your only answer to “what stops my partner overreaching” is “we will sue them”, have you read contracting with a Thai partner on what that actually involves before you rely on it?
• Has anyone described your structure to you as a way to give you full control while a Thai holds the shares? If so, name what that is before you build it.
