Breach of Contract in Thailand: Your Legal Remedies Explained
445 Views
What Counts as a Breach
Under the Civil and Commercial Code, a breach occurs when a debtor fails to perform an obligation in accordance with its true intent and purpose. That covers three broad situations: complete failure to perform, defective or partial performance, and late performance. The Code treats each of these as giving rise to a claim, and the creditor does not need to prove bad faith. What matters is that the obligation was not performed as promised.
Performance that has become genuinely impossible is treated separately. Where performance becomes impossible due to a circumstance for which the debtor is responsible, the debtor must compensate the creditor for the resulting damage. Where impossibility arises from something neither party is responsible for, the position is different and the debtor may be released, which is why force majeure wording in Thai contracts deserves careful attention.
Your Three Core Remedies
Thai law gives the injured party three main routes, and they can sometimes be combined.
The first is to demand performance. Rather than accepting the breach, you can insist that the other side does what it promised, and apply to the court to compel performance where necessary. This matters most where the subject of the contract is unique, such as a specific piece of land or a bespoke build.
The second is to terminate the contract. Thai law does not generally allow instant termination for any breach. Where one party fails to perform, the other must first fix a reasonable period and give notice requiring performance within that period. Only if the deadline passes without performance does the right to terminate arise. Skipping this notice step is one of the most common and most damaging mistakes foreign parties make, because a termination made without proper notice can itself become a breach.
The third is to claim damages. When the debtor fails to perform in accordance with the true purpose of the obligation, the creditor may claim compensation for the damage arising from that failure. Damages can be claimed alongside termination.
How Thai Courts Calculate Damages
The Code sets out a two-tier test that governs almost every contract claim. The first tier covers damage that would ordinarily arise from the non-performance, and this is recoverable as a matter of course. The second tier covers damage arising from special circumstances, and this is recoverable only where the parties concerned foresaw or ought to have foreseen those circumstances in advance.
The practical consequence is significant. If you have an unusual exposure, such as a penalty you will owe a third party, a lost resale, or a critical seasonal deadline, tell the other side in writing before you sign or before the breach occurs. Foreseeability is what converts an unusual loss into a recoverable one.
Thai courts award compensatory damages based on proven loss. They do not award punitive damages in ordinary contract cases, and they expect evidence: invoices, quotations, correspondence, accounts, and expert valuations. A claim asserted without documents rarely succeeds at full value.
Penalty Clauses Are Not Automatically Enforced
Many contracts fix a sum payable on breach, such as a daily rate for late completion. Thai law treats these as penalties, and it gives the court an express power to reduce a penalty that is disproportionately high, taking into account every legitimate interest of the creditor, not merely financial interests. Once the penalty has actually been paid, however, the right to ask for a reduction is lost.
This power is exercised in practice, and foreign parties who assume a contractual penalty will be enforced at face value are often surprised.
Supreme court judgment No. 6595/2544: A government purchaser sought to enforce a daily penalty against a defaulting supplier. The goods were valued at just over 2 million baht, the buyer had already forfeited the performance security, and it then delayed terminating for 307 days, so that accumulated daily penalties reached more than 1.26 million baht. The Supreme Court held that a contractual penalty is compensation agreed in advance, governed by Section 383, and that because the buyer had not proved loss to the full contractual amount, the penalty was excessive. The lower courts' reduction of the penalty was upheld, and the court confirmed that a debtor's earlier written agreement to pay the penalty does not prevent the court from reducing it.
The lesson runs both ways. If you are claiming under a penalty clause, be ready to prove actual loss and do not sit on the breach while the meter runs. If you are defending one, an excessive penalty is a genuine argument.
Time Limits: The Rule That Ends Most Claims
Thai limitation law is unforgiving and is not uniform. As a general rule, where no specific period is prescribed, a claim is subject to a ten-year limitation period. However, a long list of everyday commercial claims carries a much shorter two-year period. That two-year list includes traders, manufacturers, and craftsmen claiming the price of goods delivered or work done; transport operators claiming freight and fares; hotels, restaurants, and licensed venues claiming for accommodation, food, drink, and services; businesses hiring out movable property claiming rent; employees claiming wages; schools and hospitals claiming fees; and professionals including lawyers, doctors, engineers, architects, and auditors claiming for their work.
For a business chasing unpaid invoices in Thailand, this is the single most important point in this article. Many companies assume they have a decade to sue and discover far too late that their claim expired in two years.
Practical Steps When a Contract Is Broken
Read the contract first and identify the exact obligation breached and any agreed notice or dispute procedure. Put the breach in writing and set a reasonable deadline for performance, keeping proof of delivery of that notice. Quantify your loss with documents rather than estimates. Say clearly, in writing, if you have unusual exposure that the other side should be aware of. Check which limitation period applies to your type of claim before doing anything else. And take advice before terminating, because a wrongful termination transfers the legal fault to you.
Frequently Asked Questions
Can I terminate immediately if the other side breaches?
Usually not. The normal route is to give notice fixing a reasonable period for performance, and the right to terminate arises only if that period passes without performance. Some contracts and some situations allow faster termination, so the wording matters.
Can I claim damages as well as terminate?
Yes. Termination and a claim for damages are not mutually exclusive.
Will the court enforce the penalty in my contract?
Not necessarily at face value. The court can reduce a penalty it considers excessive, weighing all of the creditor's legitimate interests. Proving actual loss strengthens your position considerably.
How long do I have to sue for an unpaid invoice?
Often only two years, because most trade, service, and professional claims fall within the two-year list. The general ten-year period applies only where no shorter period is prescribed.
Does it matter that my contract is in English?
A contract in English can be valid and enforceable, but documents filed in a Thai court must be translated into Thai, and foreign-executed documents may need legalisation. Bilingual drafting from the outset avoids disputes about meaning later.

Rental disputes are among the most common legal problems foreigners face in Thailand, whether as a tenant who has lost a deposit or been locked out, or as an owner stuck with someone who has stopped paying. Thai lease law is short, old, and unforgiving of assumptions. A thirty-year villa lease can be enforceable for only three. A landlord who evicts too quickly can lose the case. A tenant who signed a clause without reading it may have given away rights the law would otherwise have protected. This guide explains how leases work under Thai law, what each side can and cannot do when things go wrong, and how eviction actually happens.
