A signed contract feels like safety, until the other side stops performing. A breach of contract in Thailand is governed mainly by the Civil and Commercial Code (CCC), and the remedies it offers (damages, specific performance, rescission and penalty clauses) work differently from what many expats and foreign companies expect from common-law systems. This guide explains what counts as a breach, what you can claim, the deadlines that quietly kill good cases, and what enforcing a judgment through a Thai court actually looks like.

What Counts as a Breach of Contract in Thailand
Thai law does not use a single statutory definition of “breach”. Instead, the Civil and Commercial Code speaks of non-performance: the debtor fails to perform the obligation at all, performs late, or performs defectively. Most written agreements used by foreigners in Thailand (sale and purchase agreements, leases, construction contracts, loan agreements, service contracts) fall under Book II of the CCC (Obligations) and the specific contract rules of Book III.
Three practical points surprise newcomers. First, most contracts are valid without any special form, but some are unenforceable in court unless written evidence exists or registration was made (land sales, long leases, mortgages). Second, Thai courts read contracts fairly literally, so the written text matters more than emails about intentions. Third, good faith under CCC Section 5 runs through everything: a party exercising rights purely to injure the other side will not be protected.
Default and the Formal Demand
Before claiming most remedies, the other party must be in default (pid nat). Under CCC Section 204, if a time for performance is fixed by the calendar, the debtor is automatically in default when that date passes. If no date is fixed, the creditor must first make a warning or demand, in practice a formal demand letter (notice) sent by a lawyer, and default begins only after that demand goes unanswered.
Under CCC Section 205, a debtor is not in default where performance failed for reasons not attributable to them. The demand letter stage is not a formality: it fixes the date from which default interest runs, it is often what brings the other side to the table, and Thai judges expect to see it. Skipping straight to court without a demand is a common and avoidable mistake in a breach of contract in Thailand dispute.
Remedies: Damages, Specific Performance and Rescission
Thai law gives the injured party three main remedies, which can sometimes be combined.
- Specific performance: under CCC Section 213, the creditor may ask the court to compel actual performance, unless the nature of the obligation does not permit it. Thai courts grant this more readily than common-law courts, especially for land transfers.
- Damages: under CCC Sections 215 and 222, the injured party can claim compensation for the damage ordinarily arising from the breach, plus special damages the breaching party could have foreseen. Thai courts award proven losses; speculative or punitive claims fail.
- Rescission: under CCC Sections 386 to 391, where the contract or the law gives a right of rescission, each party must restore the other to their former position, and rescission does not bar an additional claim for damages.
Default interest on money claims is 5% per year under CCC Section 224 (3% base rate under Section 7 plus 2%), following the 2021 amendment; older contracts citing 7.5% are applying the pre-2021 rate. A contract can set a higher rate, subject to the penalty-reduction rules below and to the Interest ceilings in specific laws.
Deposits and Penalty Clauses
Two clauses do most of the work in Thai contract disputes. An earnest deposit (mat jam) given at the conclusion of a contract is forfeited if the giver breaches, and must be returned if the receiver breaches (CCC Sections 377 and 378). Thai law does not double it: Section 378(3) only requires the deposit to be returned, and anything more has to be claimed as damages. But not every payment labelled “deposit” qualifies: the Supreme Court held in Dika 1511/2569 that a large instalment paid after the contract was concluded was not earnest money and could not simply be forfeited. See our analysis of condo deposit forfeiture in Thailand.
A penalty clause (liquidated damages) is enforceable under CCC Sections 379 to 381, but with a crucial Thai twist: under Section 383, a court may reduce a disproportionately high penalty to a reasonable amount. You cannot contract out of this judicial power. Conversely, if your actual loss exceeds the penalty, Section 380 lets you claim the difference if you can prove it.
Time Limits: Prescription Periods
Prescription (limitation) kills more contract claims in Thailand than bad evidence does. The general period under CCC Section 193/30 is ten years, but shorter periods apply to everyday claims, and under Section 193/11 the parties cannot extend them by agreement.
| Type of claim | Prescription period | CCC section |
|---|---|---|
| General contract claims (no specific rule) | 10 years | 193/30 |
| Traders, suppliers and professionals claiming payment for goods or services | 2 years | 193/34 |
| Rent arrears, interest, and other periodical payments | 5 years | 193/33 |
| Claims for damages after rescission of a contract | 10 years from rescission | 193/30, 391 |
The clock generally runs from the moment the claim can be enforced (Section 193/12). A written acknowledgment of debt or a part payment interrupts prescription and restarts it (Section 193/14). If you are close to a deadline, filing the complaint is the only certain way to stop the clock.
Suing in Thai Courts: Procedure, Costs and Enforcement
A civil claim is filed in the court where the defendant is domiciled or where the cause of action arose. Court fees are generally 2% of the amount claimed, with caps: see our note on court fees in Thai civil cases. Small claims go to the Kwaeng (district) courts; consumer cases benefit from a simplified, plaintiff-friendly procedure under the Consumer Case Procedure Act B.E. 2551.
Plan your claim once, properly. Thai procedure bars splitting one dispute into successive lawsuits: the Supreme Court dismissed an insurer’s second claim arising from a policy it had already litigated (Dika 833/2569), the trap we explain in suing twice in Thailand. A first-instance judgment typically takes around one to two years; appeals add more.
Winning is half the job. If the debtor does not pay voluntarily, enforcement goes through the Legal Execution Department: seizure and auction of assets, garnishment of bank accounts and salaries. Judgments are enforceable for ten years. Before suing, it is worth checking whether the debtor has assets in Thailand at all, and remember that a personal guarantee in Thailand gives you a second pocket to claim against, within the limits of CCC Section 686.
Arbitration and Settlement
Commercial contracts often contain an arbitration clause under the Arbitration Act B.E. 2545. Thai courts respect these clauses and will enforce awards, including foreign awards under the New York Convention, with only narrow grounds for refusal. Arbitration is faster and confidential, but costs more upfront.
Most Thai contract disputes settle. A settlement recorded as a compromise agreement under CCC Sections 850 to 852 extinguishes the original claims, so its wording deserves as much care as the original contract. Courts actively encourage mediation at the start of proceedings, and a mediated settlement entered in court becomes enforceable like a judgment.
Frequently Asked Questions
What is the time limit to sue for breach of contract in Thailand?
The general prescription period is 10 years under Section 193/30 of the Civil and Commercial Code, but many common claims are shorter: 2 years for traders and service providers claiming payment, and 5 years for rent arrears and interest.
Do I need a written contract to sue in Thailand?
Most contracts are valid orally, but several, including land sales, leases over three years and guarantees, need written evidence or registration to be enforceable in court. A written contract always makes proof far easier.
Can a Thai court reduce a penalty clause?
Yes. Under Section 383 of the Civil and Commercial Code, a court may reduce a disproportionately high penalty to a reasonable amount, and the parties cannot contract out of this power.
What default interest can I claim on a money claim?
Since the 2021 amendment, default interest under Section 224 is 5% per year (the 3% statutory rate plus 2%), unless the contract validly sets a different rate.
Can a foreigner sue for breach of contract in Thai courts?
Yes. Foreigners and foreign companies have full standing in Thai civil courts, can grant a power of attorney to a Thai lawyer, and in most ordinary cases do not need to appear in person at every hearing.

Last reviewed: 11 October 2026. Read in Thai against the Civil and Commercial Code: sections 204, 205, 213, 222, 224, 377, 378, 380, 383, 193/11, 193/14, 193/30, 193/33 and 193/34; the court fee against Table 1 annexed to the Civil Procedure Code; and Supreme Court Decisions 1511/2569 and 833/2569. Corrected: an earnest deposit is returned, not returned twofold, when the receiver breaches (section 378(3)). Not verified: the time estimates for first-instance judgments and the description of arbitration practice.
