A shareholders' agreement in Thailand is a private contract between the shareholders of a company, written alongside the articles of association. It does not replace the Civil and Commercial Code. The Code already decides who appoints directors, how many shareholders make a quorum, how votes are counted and how shares transfer. The agreement is drafted against those rules.
Last reviewed 3 October 2026. This section describes the Civil and Commercial Code sections cited, read against the Thai text. It is general information and not advice on a specific company or agreement.
What does the Civil and Commercial Code decide before a shareholders' agreement does?
The Code fixes the default rules on directors, meetings, voting and share transfers for a Thai limited company. A shareholders' agreement works within these rules. The table lists the sections that matter most and what each means for the drafting of a shareholders' agreement in Thailand.
| Topic | What the Code provides | Section |
|---|---|---|
| Appointing and removing directors | Only the general meeting may appoint or remove a director | 1151 |
| Quorum | At least two shareholders or proxies holding at least one quarter of the capital | 1178 |
| Counting votes | On a show of hands each shareholder has one vote; on a poll each has one vote per share | 1182 |
| Tied vote | The chairman of the meeting has a casting vote | 1193 |
| Special resolution | At least three quarters of the total votes of the shareholders present and entitled to vote | 1194 |
| Changing the articles | Requires a special resolution | 1145 |
| Transfer of registered shares | The articles may restrict transfer; the transfer is written, signed and witnessed; it is effective against the company and third parties only once registered | 1129 |
| Directors' duties | Diligence of a prudent businessperson; no competing business without shareholder approval | 1168 |
Because section 1151 gives the appointment of directors to the general meeting, a board-seat right in a shareholders' agreement is a promise about how shareholders will vote. It is not an appointment power. The agreement must therefore bind the parties to vote in a particular way at the meeting.
Which shareholding percentages decide a special resolution?
A special resolution passes only with three quarters of the votes of the shareholders present and entitled to vote under section 1194. A holder of more than one quarter of the votes present can therefore prevent it. That threshold is the practical measure of a minority's protection under the Code.
| Share of votes present | Effect on a special resolution |
|---|---|
| Three quarters or more | Can pass the resolution, provided the quorum under section 1178 is met |
| More than one quarter | Can prevent the resolution |
| One quarter or less | Cannot prevent it alone |
The measure is votes present, not shares issued. A minority above one quarter of the shares can lose a special resolution if its holder is absent and the shareholders present hold three quarters of the votes present. The quorum rule in section 1178 asks for two shareholders or proxies and one quarter of the capital, so attendance matters. A shareholders' agreement can address it with an undertaking to attend.
Special resolutions govern the changes that matter most to a joint venture. These include amendment of the articles under section 1145 and dissolution under section 1236(4), described in our guide to liquidating a company in Thailand.
How does a tied vote work in a 50/50 company?
When votes are equal, section 1193 gives the chairman of the meeting a casting vote. In a company split equally between two shareholders, the person who chairs the meeting can therefore decide a tied ordinary vote. The articles and the agreement should state who chairs, because the Code attaches the casting vote to the chair.
A shareholder dispute that no vote can resolve is a different problem. Section 1237(5) lets the court dissolve a company where other circumstances prevent it from continuing, as published summaries describe the paragraph. Our guide to shareholder disputes in Thailand covers the remedies.
Can a shareholders' agreement restrict the transfer of shares?
Section 1129 allows the articles to restrict the transfer of registered shares. A pre-emption clause or a drag-along clause in a shareholders' agreement binds the parties by contract. The Code separately requires a written, signed and witnessed transfer, and the transfer takes effect against the company and third parties only when it is registered.
Registration therefore decides when a transfer is effective against the company. Our share transfer guide sets out the related sections on foreign ownership, land and competition review.
How does a shareholders' agreement interact with the foreign ownership rules?
Section 4 of the Foreign Business Act tests foreign status by the capital that foreigners hold, with further limbs for partnerships and for juristic persons connected to those in the first limbs. A shareholders' agreement does not change the shareholding on which that test turns. Rights given to a foreign party beyond its shareholding raise the nominee provisions of section 36.
Our guides to the 49/51 shareholding structure and to the Foreign Business Act explain these points. For the drafting of the contract itself, see our contract lawyer page.

The Classic Lesson from Business Takeover Drama
In business, we often see disputes when one shareholder gains control at the expense of others, so-called “business takeover drama.” These situations usually start the same way: friends or partners form a company, relying only on trust or verbal promises. At the beginning, when the business is small, this seems fine. But as the company grows and assets increase, conflicts often emerge resulting in broken relationships and sometimes the loss of the entire business.
The simple lesson? A properly drafted shareholder agreement is worth far more than its cost; partners can prevent years of conflict.

What is a Shareholder Agreement?
A shareholder agreement is a private contract between shareholders that supplements the company’s Articles of Association. It sets out clear rules on how the business will be managed, how decisions will be made, and how disputes will be resolved.
Unlike the company’s official registration documents, a shareholder agreement provides flexibility and protection tailored to the needs of the business partners.

Key Clauses Every Shareholder Agreement Should Include
1. Board Representation
Example: If three people hold shares in the ratio 45% / 45% / 10%, the two larger shareholders might each appoint one director, while the smaller shareholder has no appointment right. This ensures balance and prevents one side from gaining full control through small additional purchases.
2. Right of First Refusal (ROFR)
This clause prevents shareholders from secretly selling shares to outsiders. If one shareholder wishes to sell, they must first offer the shares proportionally to the other existing shareholders.
3. Tag-Along and Drag-Along Rights
These protect minority shareholders.
-
- Tag-along: if majority shareholders sell, minority holders can sell on the same terms.
-
- Drag-along: if a buyer wants 100% of the company, minority shareholders can be required to sell, ensuring a clean exit.
4. Deadlock Clause
If shareholders with equal power cannot agree, the business may freeze (deadlock). A classic solution is the “Russian Roulette” mechanism: both sides submit offers to buy out the other, and the higher offer wins. This ensures one clear owner and prevents long-term paralysis.
Why a Shareholder Agreement Matters in Thailand
Under Thai law, holding more than 50% of shares allows control over shareholder resolutions, such as removing directors or appointing family members. Without protective clauses, minority partners risk losing their influence entirely.
- A shareholder agreement:
- Protects minority shareholders.
- Prevents hostile takeovers.
- Clarifies partner expectations from day one.
- Provides clear exit strategies.
