Nominee Shareholders in Thailand: Why They Are Risky (2026 Guide).

The short version: nominees are a criminal risk, not a shortcut

When a foreigner wants to run a business that the Foreign Business Act reserves for Thai-majority companies, someone usually suggests the "easy" answer: find Thai shareholders to hold 51% on paper while the foreigner keeps the money and control. That arrangement is a nominee structure, and it is illegal.

It is not a grey area or a technicality. Using nominees is a criminal offence under the Foreign Business Act, it exposes both the Thai holder and the foreigner to prosecution, and Thai authorities have made a point of investigating it. This guide explains what a nominee arrangement is, why it is illegal, how it gets caught, and the legal routes that do the same job safely. It is part of the broader guide to setting up a company in Thailand as a foreigner.

What a nominee arrangement is

A nominee shareholder is a Thai person or Thai company that holds shares on a foreigner's behalf without genuinely investing or controlling anything. On the share register, the company looks Thai-majority. In reality, the foreigner put up the capital, takes the profit, and runs the business, while the Thai "shareholders" are stand-ins, often paid a small fee to lend their names.

The point of the structure is to make a foreign-controlled company appear Thai so it can avoid the Foreign Business Act's ownership limits. That appearance is exactly what the law treats as the offence.

It is worth being clear about what is not a nominee arrangement. A Thai partner who actually invests their own money, shares the risk, and has real rights in the company is a genuine shareholder, not a nominee. Having Thai shareholders is normal and lawful. What the law targets is fake ones: people paid to lend their names while the foreigner keeps control.

Why it is illegal

The Foreign Business Act makes it an offence for a Thai national to hold shares as a nominee to help a foreigner get around the Act, and for the foreigner to allow or use that arrangement. Both sides commit the offence.

The penalty is criminal: imprisonment of up to 3 years, a fine of 100,000 to 1,000,000 THB, or both. On conviction the court also orders the arrangement to stop, and continued operation after that order adds a daily fine. The exact wording of the daily fine sits in the Act's penalty provisions; the headline point is that this is jail-and-fine territory, not a slap on the wrist.

How it gets caught

Enforcement has become more active, not less. The Department of Business Development and the Department of Special Investigation (the DSI, which handles the more serious cases) have run repeated checks on suspected nominee structures, with particular attention to property, tourism, and hospitality.

The main tool is simple: source of funds. If a Thai shareholder is recorded as owning 51% of a company, the authorities can ask them to show that they actually had the money to pay for those shares. A Thai name attached to a stake they plainly could not afford is the classic red flag. So is one Thai person appearing as a major shareholder across many unrelated companies, which financial-flow analysis can surface. Cases can also be referred to the Anti-Money Laundering Office, which adds a second front of liability.

In short, the structure that looks fine on the share register often does not survive a look at the bank statements behind it.

What happens if you are caught

The consequences land on everyone involved and on the business itself.

• Criminal liability for both parties. The Thai nominee and the foreigner each face the prison and fine exposure above.
• The company is treated as foreign. Once the Thai shareholding is unmasked as nominee, the company is what it always really was: a foreign company operating a restricted activity without permission, which is itself an offence.
• The business can be forced to stop. Courts can order the activity to cease, and the company may have to restructure, divest, or wind down.
• Property can be challenged. Where land or property was bought through the structure, the holding can be challenged under the Land Code.

The structure that was meant to save time and money becomes the thing that ends the business.

The legal alternatives

The reassuring part is that the goals people reach for nominees to achieve (foreign ownership and control of a real Thai business) can usually be reached legally. There are four main routes, all covered elsewhere in this cluster.

• BOI promotion. If your activity qualifies, the Board of Investment can allow up to 100% foreign ownership, plus tax and other incentives. The company holds a Foreign Business Certificate rather than needing a Thai majority.
• The Treaty of Amity. If the owners are American, the Amity treaty allows up to 100% US ownership in most sectors.
• A Foreign Business License. Where neither of the above fits, a foreigner can apply to the DBD for a Foreign Business License to run a restricted activity as a foreign-majority company.
• A genuine Thai-majority company. A real Thai partner can hold the majority while the foreign shareholder keeps meaningful, lawful protections.

What "genuine" actually means

The last route is the one people most often try to fake, so it is worth being precise. It is entirely lawful to have a Thai-majority company in which the foreign minority has real protections: preferential or weighted voting shares, board representation, veto rights over key decisions, and a proper shareholder agreement. Thai company law allows different classes of shares with different voting rights.

The line is substance over form. These mechanisms are legitimate when they sit on top of a real arrangement, with Thai shareholders who genuinely invested and genuinely participate. They become illegal the moment they are used to engineer total foreign control over passive, paid Thai names. A structure that uses voting tricks to make a "Thai-majority" company foreign-controlled in everything but the share register is the same nominee offence in a smarter suit.

This is exactly the kind of structuring where the detail decides whether you are compliant or exposed, and it is not something to improvise from an article.

When a lawyer helps

A corporate lawyer does two useful things here. First, they tell you honestly whether you even need a Thai-majority structure, because many businesses qualify for BOI, Amity, or a licence and never need one. Second, if a Thai-majority company is the right answer, they build it so it is genuinely compliant: real shareholders, a proper agreement, and lawful control mechanisms that reflect the real deal.

If a nominee structure already exists and you are worried about it, that is a dispute and compliance question worth raising with a lawyer sooner rather than later, because unwinding it voluntarily is far better than having it unwound for you.

A note on what this guide is

This is general information to help you understand the law on nominee shareholders, not legal advice, and it is not a guide to building any particular structure. The rules are enforced and the penalties are criminal. For your specific situation, speak with a qualified Thai lawyer, and confirm the current position with the Department of Business Development.
