Civil Litigation in Thailand: The Court Process and How Long It Takes
2 Views
Thailand's Three-Tier Court System
Civil disputes between private parties are heard by the Courts of Justice, which are organised into three levels. At the base are the Courts of First Instance, where almost every case begins and where the facts are decided. Above them sits the Court of Appeal, and at the top is the Supreme Court, known in Thai as the Dika Court. Thailand is a civil-law country: judges apply codified statutes rather than binding precedent, and civil procedure is governed chiefly by the Civil Procedure Code of 1934.
Which Court Hears Your Case
At first instance, the right court depends on the value and subject matter of the claim. District Courts (Kwaeng Courts) handle smaller civil claims up to 300,000 baht under streamlined rules. Larger ordinary claims go to the Civil Court or the relevant Provincial Court. Certain subjects are reserved for specialised courts — intellectual property and international trade, labour, tax, bankruptcy, and juvenile and family matters each have their own court, and appeals from them run to a dedicated Court of Appeal for Specialised Cases rather than the regional appeal court.
Before You File: Limitation Periods and Preparation
Every claim has a limitation period, and missing it can end a case before it starts. Many contract claims carry a general limitation of up to ten years, while some claims — such as certain tort or specific statutory claims — are much shorter. Because Thai litigation is document-driven, the groundwork matters enormously: preserve original documents, assemble a clear timeline, gather your evidence, and, where there is a real risk that the other side will move or hide assets, consider applying for interim protective measures early. Thai courts grant provisional injunctions sparingly, so a well-evidenced application is essential.
Stage One: Filing the Claim
A case begins when the plaintiff files a plaint (kham fong) setting out the facts, the legal basis, and the relief sought. Court filing fees for most money claims are calculated as a percentage of the amount in dispute — broadly around two percent — subject to a statutory cap, so very large claims do not attract unlimited fees. The plaint and its supporting documents define the boundaries of the case, so precise drafting at this stage shapes everything that follows.
Stage Two: Service and the Defendant's Answer
Once the plaint is accepted, the court arranges for the plaint and summons to be served on the defendant through court officers. The defendant must file an answer (kham hai kan) within fifteen days of service, though extensions are commonly granted. The defendant may also raise a counterclaim at the same time. If the defendant fails to answer or appear, the court can proceed to a default judgment in the plaintiff's favour.
Stage Three: Mediation
Before a case goes to trial, the court will usually direct the parties to mediation, which is mandatory in many courts, particularly in Bangkok. Mediation is not a formality — Thai courts actively encourage settlement, and a large share of civil cases resolve at this stage. A settlement can be recorded as a compromise judgment, which is faster, cheaper, and final, avoiding the uncertainty of trial and appeal.
Stage Four: Settling the Issues and Trial
If mediation fails, the court holds a preliminary hearing to define the specific issues to be tried. Thailand does not have common-law-style discovery; instead, each party must submit its intended evidence and witness lists in advance. Trials are heard by judges alone — there is no jury — and the judge takes an active role in questioning witnesses and examining evidence. Modern practice favours concentrated, continuous hearings scheduled over consecutive days rather than trials dragged out over many months. Foreign documents are admissible only after they have been authenticated, legalised, and translated into Thai, and a non-Thai-speaking party will need a court interpreter.
Stage Five: Judgment
After the trial concludes, the court issues a reasoned written judgment, typically within about thirty days, setting out its factual findings and legal reasoning. The judgment is binding immediately, but it is not final while an appeal remains possible. Thai courts award compensatory damages based on losses actually proven; punitive damages are generally not available except in specific statutory areas such as intellectual property. Awarded legal costs tend to be modest, and in most cases each side effectively bears its own lawyers' fees.
Stage Six: Appeals
A party wishing to appeal a first-instance judgment must do so within one month of the judgment. The Court of Appeal reviews both the facts and the law, working largely from the written record rather than re-hearing live evidence, and new evidence is admitted only exceptionally. A further appeal to the Supreme Court is not automatic. Since a 2015 reform, the Supreme Court operates a permission-based system: a litigant must petition within one month of the Court of Appeal's judgment, and permission is granted only for cases raising important legal questions, resolving conflicting decisions, or affecting the public interest. Most petitions are not admitted, which means the Court of Appeal's decision is final in the majority of cases.
Stage Seven: Enforcing the Judgment
Winning is not the same as being paid. If the losing party does not comply voluntarily, the successful party enforces the judgment through the Legal Execution Department of the Ministry of Justice. The court issues an execution writ, and enforcement can include seizing and auctioning the debtor's property, attaching bank accounts, and garnishee orders against money owed to the debtor. Enforcement against land and other registered property involves additional steps at the relevant government office. An appeal does not automatically suspend enforcement; a judgment debtor who wants to halt execution pending appeal must apply for a stay and may be ordered to post security.
How Long Does It All Take?
Thai litigation has long had a reputation for being slow, and the government has taken concrete steps to address it. The Timeframe for Judicial Proceedings Act of 2022, effective from 23 January 2023, requires the courts to publish target times for each stage of a case, and the accompanying judicial regulation sets those targets: broadly one year for a contested civil case at first instance, six months to one year at the Court of Appeal, and around one year at the Supreme Court for cases granted permission. Non-contentious or default cases at first instance aim for six months. If a stage runs over its target, the parties can ask the court for an explanation, and the court must respond within fifteen days.
In practice, actual durations depend on complexity. A simple debt claim is often resolved within six to twelve months. A contested contract dispute may take twelve to eighteen months at first instance. Inheritance and family matters, which frequently involve multiple parties, can extend beyond two years. Where a case runs the full course through both appeal levels, finality can take three to four years or more. The reforms have visibly accelerated cases that previously stalled, but no timeline is guaranteed, and a determined opponent can still lengthen proceedings.
Special Notes for Foreigners
Two points regularly catch foreign litigants out. First, a judgment obtained abroad is not automatically enforceable in Thailand. Thai courts do not simply register a foreign judgment; in most cases you must bring a fresh action in Thailand, using the foreign judgment as evidence rather than as a directly enforceable order. Second, for international commercial disputes, arbitration is often a stronger route: Thailand is a party to the New York Convention, so foreign arbitral awards are generally enforceable here, subject to limited defences. Where confidentiality, a specialist tribunal, or cross-border enforcement matters, an arbitration clause negotiated at the contract stage can save years later.
Practical Tips to Reduce Delay
Draft the plaint or defence precisely and completely from the outset. Avoid unnecessary motions that invite adjournments. Prepare and legalise foreign documents early, since translation and authentication take time. Attend every hearing and submit all evidence on schedule. Take mediation seriously — a fair settlement almost always beats years of litigation. And engage bilingual counsel who can manage both the Thai procedure and the foreign-evidence requirements.
Frequently Asked Questions

Not automatically. You will usually need to bring a fresh case in a Thai court, relying on the foreign judgment as evidence.
4. Do I have to appear in person?
Personal appearance is required at certain key stages, though much of the process is documentary. Foreign parties who do not speak Thai will need an interpreter for hearings.
5. What does it cost to file?
Court filing fees for money claims are broadly around two percent of the amount claimed, subject to a statutory cap. Lawyers' fees are separate and usually not recoverable from the losing side.

If you own a condominium, hold a Thai bank account, run a company, or simply spend a large part of the year in Thailand, you almost certainly need a Thai will. Many foreigners assume the will they signed back home will take care of everything. In reality, a foreign will can be enforced in Thailand only after a slow and expensive court procedure — and in the meantime your bank accounts may be frozen and your family left in limbo. This guide explains how Thai inheritance law works, what happens if you die without a will, the special rules that apply to foreigners, and the new will-registration reforms that took effect in 2026.
