Key takeaways
- An arbitral award is not self-executing in Thailand. If the losing party does not pay, you must apply to a Thai court to enforce it.
- The enforcement clock runs for three years from the date the award becomes enforceable. Miss it and a good award can become worthless.
- Thai courts treat enforcement as the norm and may refuse only on narrow, defined grounds. A losing party cannot use enforcement to re-argue the merits.
- For any contract with a foreign counterparty holding assets in Thailand, an arbitration clause is far more enforceable here than a foreign court judgment.
An award is a right, not a remedy
An arbitral award does not enforce itself. If the losing side simply refuses to pay, you cannot seize assets on the strength of the award alone. You must petition a Thai court to recognise and enforce it. Critically, there is a deadline: the enforcement petition must be filed within three years from the date the award becomes enforceable. A party that sits on a favourable award, or files without the certified Thai translations of the award and the arbitration agreement that the court requires, can watch a winning case lapse on a technicality.
Enforcement is the norm; refusal is the exception
The Thai courts are supportive of arbitration. On application, a court recognises an award as binding and enforces it. It may refuse only on narrow grounds: where the resisting party proves a specific defect, such as incapacity of a party, lack of proper notice, or an award that goes beyond the scope of what was submitted to arbitration; or where the court itself finds the dispute was not one that could be arbitrated, or that enforcement would be contrary to public order. The losing party cannot reopen the facts or the reasoning. That narrowness is the point of arbitration, and it is why a well-run arbitration produces a durable result.
Set-aside is a narrow, fast-closing door
A party unhappy with an award has one route, and it is not an appeal on the merits. Its only recourse is to apply to set the award aside, on the same narrow grounds, and it must do so within ninety days of receiving the award. Two practical consequences follow. First, procedural objections must be raised during the arbitration itself; a party that stays silent and saves them for later usually waives them. Second, the ninety-day window is short, so a party on either side must move quickly and deliberately.
Why this matters for cross-border deals
This is where the choice of dispute-resolution clause becomes decisive. Thailand has no general regime for enforcing foreign court judgments: a party holding a judgment from a foreign court must, in effect, sue again in Thailand from the beginning. A foreign arbitral award is treated very differently. Because Thailand is a party to the New York Convention, a foreign award can be enforced through the Thai courts. For any contract with a counterparty whose assets sit in Thailand, that difference is a strong reason to choose arbitration over a foreign-court clause at the drafting stage, long before any dispute arises.
From our practice Clients often come to us holding an award that the losing side simply ignores. The work that follows, filing within the enforcement period, preparing the certified translations in advance, and meeting a set-aside challenge on the narrow grounds the law allows, is what turns a paper award into a recovery. It is the part of arbitration that is easy to underestimate until it is the only thing that matters.

What to do now
Diarise the three-year enforcement clock the moment an award is issued, and keep certified Thai translations ready so filing is never delayed. Raise every procedural objection during the arbitration, not after. And when you negotiate your next cross-border contract, treat the dispute-resolution clause as a commercial term, not boilerplate: for a counterparty with Thai assets, a well-drafted arbitration clause is often the single most valuable line in the agreement.
