Divorce in Thailand: Grounds, Procedure and Your Rights

Two Routes, and Only Two
Thai law recognises exactly two ways to dissolve a marriage: by mutual consent, or by judgment of the court. There is no third option, and no administrative process for a divorce that one spouse opposes.

A divorce by mutual consent must be made in writing and signed by at least two witnesses. Critically, where the marriage was registered under Thai law, the consensual divorce becomes effective only once the divorce itself has been registered. An agreement signed at home and left in a drawer changes nothing; until it is registered at the district office, you remain married.

The second route is a court judgment. This is required whenever one spouse refuses to divorce, refuses to agree terms, or cannot be located. Contested divorces are heard by the Youth and Family Court, not by a district office, and the person filing must plead and prove a recognised ground.

The Ten Grounds for Divorce
The Civil and Commercial Code sets out an exhaustive list of grounds. Following the Marriage Equality Act, these provisions are now drafted in gender-neutral terms and apply identically to all married couples.

The grounds are:
One. A spouse maintains or honours another person as a spouse, commits adultery, has habitual sexual relations with another, or habitually engages in or accepts acts with others for sexual gratification.

Two. A spouse is guilty of serious misconduct, whether or not it amounts to a criminal offence, where it causes the other serious shame and humiliation, causes the other to be insulted or hated for remaining married to them, or causes excessive injury or trouble judged against their circumstances and standing.

Three. A spouse seriously harms or tortures the body or mind of the other, or seriously insults or humiliates the other or the other's ascendants.

Four. A spouse wilfully deserts the other for more than one year.

Four point one. A spouse has been sentenced by final judgment and actually imprisoned for more than one year, for an offence in which the other spouse took no part, gave no consent, and was not complicit, and where remaining married would cause the other excessive injury or trouble.

Four point two. The spouses have voluntarily lived apart, because they could not live together peacefully, for more than three years, or have lived apart under a court order for more than three years.

Five. A spouse has been declared disappeared by the court, or has left their domicile for more than three years with no reliable news of whether they are alive or dead.

Six. A spouse fails to give proper maintenance and support to the other, or acts in a manner seriously adverse to the marriage, to a degree causing the other excessive trouble judged against their circumstances and standing.

Seven. A spouse has been continuously insane for more than three years, the insanity is difficult to cure, and it is of such severity that continued cohabitation is impossible.

Eight. A spouse breaches a written bond of good behaviour. Even here the court retains discretion and may refuse a divorce where the conduct behind the bond was trivial or unimportant to living together peacefully.

Nine. A spouse has a serious communicable disease that may endanger the other, and the disease is chronic and incurable.

Ten. A spouse has a physical condition permanently preventing sexual relations or sexual gratification of the other.

The Ground Foreigners Rely On Most, and Get Wrong
Separation is the most commonly attempted ground, and it is also the most commonly misunderstood. The three-year separation ground requires more than the passage of time. It requires that both spouses voluntarily separated, and that the separation was because they could not live together peacefully as spouses. A separation imposed by one spouse walking out does not qualify, no matter how many years pass.

Supreme court judgment No. 2670/2556: The spouses had signed a written compromise recording that they no longer wished to live together as husband and wife, and more than three years had elapsed before the claim was filed. The Supreme Court nonetheless refused the divorce. The evidence showed that the claimant had left the home himself while the defendant remained willing to continue the marriage, and the claimant had failed to prove any conflict justifying separation. The court held that the document showed only that the claimant alone had chosen to separate, which does not amount to voluntary separation because the couple could not live together peacefully. The ground was therefore not established, however long the parties had lived apart.

Supreme court judgment No. 4815/2539: Here the separation ground was made out. The claimant had left the shared home for a legitimate family reason, both parties had intended to register a divorce, and more than three years had passed, so the divorce was granted. However, the wife's claim for a living allowance failed. The court held that a living allowance under Section 1526 requires the ground for divorce to be the fault of one spouse alone, and where the divorce rests on mutual voluntary separation, no such allowance can be claimed.

Defences Your Spouse Can Raise
Two defences arise directly from the Code. Where a spouse consented to or was complicit in the conduct relied on, they cannot use grounds one or two against the other. And where a physical incapacity under ground ten was caused by the claimant, the claimant cannot rely on it.

Beyond these, the practical defence in most contested cases is simply insufficient evidence. Thai courts require the ground to be pleaded properly and proved, and a claim that omits an essential element of the ground can fail on the pleadings alone.

The One-Year Deadline
This is the single most important practical rule in Thai divorce law, and it is the one foreigners most often miss. The right to sue on the grounds of adultery and similar conduct, serious misconduct, serious harm or insult, and failure to maintain or acting adversely to the marriage lapses one year from the date the claimant knew or ought to have known the facts relied on. The same one-year limit applies to a claim for compensation.

Conduct that can no longer found a divorce claim is not entirely wasted. It may still be used as supporting evidence in a divorce brought on another ground. But as a standalone basis for divorce, it is gone.

Compensation
Where a divorce is granted on the ground of adultery and similar conduct, the innocent spouse may claim compensation from the guilty spouse and also from the third party who was maintained or honoured, or who caused the divorce. There is a further right to claim compensation from a person who has behaved towards your spouse in the manner of a lover, or who has publicly held themselves out as being in such a relationship. A spouse who consented to or connived at the conduct cannot claim.

Separately, where a divorce arises from serious harm, desertion, or failure to maintain, and the responsible spouse deliberately brought about that situation so that the other could not endure it and had to sue for divorce, the innocent spouse may claim compensation from them.

Living Allowance, and the Trap That Destroys It
A living allowance, the closest Thai equivalent to spousal maintenance, is not routine. It is available only where the ground for divorce is the fault of one spouse alone, and the divorce will leave the other impoverished because they have insufficient income from property or from the work they did during the marriage. Even then, the court has discretion over whether to award anything, weighing the payer's ability and the recipient's circumstances.

Here is the trap. The right to a living allowance is extinguished unless it is claimed by action or counterclaim within the divorce case itself. Raise it later and it is lost permanently.

Property and Children
Property division and arrangements for children are decided alongside the divorce. Marital property is split between the spouses while personal property remains with its owner, a subject with enough traps of its own that we have covered it separately. Parental power and child support are likewise determined either by written agreement in a consensual divorce or by the court in a contested one, judged by the welfare and interests of the child.

Special Points for Foreigners
If your marriage was registered outside Thailand, you generally cannot divorce at a Thai district office, because the administrative registration route is built around marriages registered under Thai law. In practice that means a court application, and it makes early advice essential.

A divorce granted abroad is not automatically effective in Thailand for all purposes, and recognition may require a Thai court process, particularly where Thai-registered property or a Thai marriage record is involved. Foreign documents filed in a Thai court must be translated into Thai and, depending on their origin, legalised. Court hearings are conducted in Thai, and a party who does not speak Thai will need an interpreter.

Practical Steps
Establish first whether your spouse will consent, because that single fact determines your route, your cost, and your timeline. Preserve evidence early, including messages, photographs, financial records, and witness details. Check the one-year deadline before anything else if your case involves adultery, misconduct, violence, or failure to maintain. Decide on compensation and living allowance before filing, not after, because both must be raised in the divorce case. And do not sign a consent divorce agreement at the district office without advice, since the terms on property and children are difficult to reopen later.

Frequently Asked Questions

Can I divorce in Thailand if my spouse will not agree?
Yes, but only through the Youth and Family Court, and only by proving one of the statutory grounds. Thai law does not recognise irreconcilable differences.

We have been separated for years. Is that enough?
Not by itself. The separation must have been voluntary on both sides and must have arisen because you could not live together peacefully, and it must exceed three years.

Can I claim against my spouse's lover?
Yes. Where the divorce is granted on the adultery ground, compensation may be claimed from the third party as well as from your spouse, subject to the one-year time limit.

Will I receive spousal maintenance?
Only if the divorce is the fault of your spouse alone and you will be left impoverished, and only if you claim it within the divorce proceedings themselves.

We married abroad. Can we divorce at the amphur?
Usually not. Marriages registered outside Thailand normally require a court application rather than administrative registration, so take advice on your specific situation.
