Ending a marriage in Thailand splits into two very different paths: a fast administrative (uncontested) divorce at the district office (amphur) when both spouses agree, or a slower contested divorce through the Thai courts when they don’t — where you must prove a statutory ground. This plain-English guide walks through both routes, how marital property (sin somros) is divided versus personal property (sin suan tua), child custody and parental power, whether a prenup holds up, how a Thai divorce is recognised abroad, and the step most foreigners forget — the visa fallout if you live here on a marriage-based Non-O. Unbiased, never paid placement.
If you both agree, a Thai divorce is a same-day administrative registration at the amphur (a Kor Ror 6 certificate). If you don’t, it’s a contested court case needing a statutory ground. Marital property (sin somros) is split 50/50 by default; personal property (sin suan tua) stays put. Children are decided by best interests. And crucially — if you live here on a marriage visa, divorcing ends that visa basis, so plan the switch early.
Thai divorce comes in two fundamentally different shapes. An administrative (uncontested) divorce — also called a mutual-consent divorce — is for couples who agree both to end the marriage and on the terms (property, children, support). It is registered at a district office (amphur), the same kind of office where Thai marriages are registered. A contested divorce is for when the spouses disagree — one wants out and the other refuses, or they cannot settle property or custody — and it runs through the Thai courts, where the petitioning spouse must prove a legal ground. The uncontested route is faster, cheaper and far less stressful; the contested route is slower, adversarial and lawyer-driven. Which is available to you turns largely on whether your spouse will cooperate and where the marriage was registered. This is the immigration- and property-focused overview — the mirror image of the marriage visa guide.
If both spouses agree, the amphur route is straightforward and often done in a single visit. Typically you need:
The registrar records the divorce and issues a divorce certificate (Kor Ror 6). The key limitations: the marriage generally must have been registered in Thailand, and both parties must attend — you cannot use this route to divorce a spouse who won’t come. A foreign-registered marriage may not be divorceable at an amphur at all, which pushes you toward the courts or your home country.
When consent is missing, the petitioning spouse must go to court and prove a statutory ground under the Civil and Commercial Code. The recognised grounds include, broadly:
A contested case is slower, costlier and evidence-heavy. Grounds carry technical thresholds and time periods — this is exactly where you need a licensed Thai family lawyer, not a checklist.
Thai law sorts assets into two buckets. Sin suan tua (personal property) is what each spouse owned before the marriage, plus inheritances and certain personal gifts received during it — this stays with that spouse. Sin somros (marital/community property) is generally what was acquired during the marriage and income earned during it — and on divorce the default is an equal (50/50) split. A valid prenuptial agreement can change these defaults.
A foreigner generally cannot own land in Thailand, so even where the family home sits on Thai-owned land, the foreign spouse usually has no land-ownership claim — though condominium units (which foreigners can own under the foreign-quota rules) and other assets are treated differently. This is one reason foreign property arrangements in Thailand are best understood before a marriage ends, not during the split. Background: foreign condo ownership and Thai title deeds.
Thai law uses the concept of parental power rather than the English idea of custody. In an administrative divorce the parents can agree, in the divorce agreement, who holds parental power and how child support works. In a contested case the court decides on the welfare and best interests of the child, and may award sole or joint parental power and order support. Unmarried fathers have weaker automatic rights than married ones, which is why marital status and legitimation matter. The hardest cases are cross-border ones — where one parent wants to move a child to another country — which can raise Hague Convention child-abduction issues. Custody and relocation are the most contested, most emotional part of any foreign divorce; specialist advice is essential. For family-life context see moving with family and having a baby in Thailand.
A prenuptial agreement can be valid and enforceable in Thailand — but only if it is done correctly and on time. To be effective it must be in writing, signed by both spouses and two witnesses, and registered together with the marriage at the amphur at the moment of marriage registration. A “prenup” signed after the wedding, or never registered with the marriage, is generally not effective for these purposes. A valid Thai prenup mainly governs property — defining what is sin suan tua versus sin somros and how assets divide — and it cannot override the court’s duty to decide children’s matters by their best interests. If you hold significant assets, or assets in more than one country, have the prenup drafted by a lawyer before you register the marriage; it is far harder to fix afterwards.
A Thai divorce is often recognised in your home country — but not automatically, and the rules are your home jurisdiction’s, not Thailand’s. A properly registered administrative divorce (with the Kor Ror 6) or a Thai court decree is generally accepted in many countries, sometimes after legalisation/apostille and certified translation, and sometimes after registering it with your own authorities. Some countries scrutinise mutual-consent administrative divorces more closely than court decrees. If you married in your home country and only divorce in Thailand, recognition can get complicated — occasionally it is cleaner to divorce where you married, or in both places. Recognition matters for remarriage, taxes and inheritance back home, so confirm the path with your embassy or a lawyer in your own country before you rely on a Thai divorce being final everywhere.
If you live in Thailand on a marriage-based Non-Immigrant O and its one-year extension, your right to stay is built on the marriage. Once you divorce, the legal basis for that extension ends — you generally cannot keep renewing it, and you should not assume the remaining months on your stamp are guaranteed. In practice immigration expects you to leave or switch to another visa basis before or around the time your permission lapses. A work permit tied to the marriage status can also be affected. Plan the transition early, as part of the divorce, not after:
Also revisit your TM30 & 90-day reporting once your address or status changes.
A divorce usually means a change of home — one spouse moving out, or both downsizing. Because a foreigner’s land claim is limited and a marriage-tied lease or address may no longer fit, it’s common to take a fresh 12-month lease in your own name, sized to a single-occupant budget rather than a family one. Keep the practicalities in mind: a clean lease and a correctly filed TM30 matter even more when your visa basis is changing, since your next visa application will want proof of where you now live. Model a realistic solo monthly number first with the cost-of-living calculator, then explore areas that suit a reset.
