International Divorce: When Thai & Foreign Law Collide

Which Country Has Jurisdiction?

Thai courts have jurisdiction over divorce if: (1) the marriage was registered in Thailand, (2) either spouse is domiciled in Thailand, or (3) either spouse is a Thai national. In practice, if you live in Thailand, you can divorce here — regardless of where you married. However, your home country may also claim jurisdiction, creating potential for parallel proceedings.

Choice of Law

Thai courts apply Thai law to divorces filed in Thailand — even if both spouses are foreign. This means Thai grounds for divorce apply (Civil and Commercial Code B.E. 2468 (1925) Sections 1516). The 10 grounds include: adultery, misconduct, physical harm, desertion (1+ year), imprisonment (1+ year), and separation for 3+ years. Mutual consent divorce is also available.

Asset Division

Thai law divides marital property (Sin Somros) equally — 50/50 — regardless of who earned it. Personal property (Sin Suan Tua — assets owned before marriage or received as gifts/inheritance) stays with the original owner. Cross-border complication: Thai courts can only divide assets within Thailand. For overseas assets, you may need separate proceedings in the country where the assets are located.

Child Custody

Thai courts prioritize the "best interests of the child." Factors: child's age, primary caregiver, financial ability, stability, child's preference (if old enough). For children under 7, courts generally favor the mother. Hague Convention: Thailand is a Contracting State to the 1980 Hague Convention on the Civil Aspects of International Child Abduction (acceded 14 August 2002; in force for Thailand 1 November 2002). The Thai Central Authority sits within the Ministry of Social Development and Human Security. A return application is filed through your own country's Central Authority, which transmits it to Thailand's. In practice enforcement is slow and a Thai court order is still required for in-Thailand enforcement, so engage Thai family-law counsel in parallel — but do not assume Convention remedies are unavailable to you.

Enforcing Foreign Divorce Judgments

Thailand does not automatically recognize foreign divorce judgments. To enforce a foreign divorce decree in Thailand: (1) obtain a certified copy of the judgment, (2) have it translated into Thai and certified by MFA, (3) file a new case at Thai court to recognize the foreign judgment. The court will examine whether the foreign proceedings were fair and did not violate Thai public policy.

Practical Steps

1. Consult both a Thai lawyer AND a lawyer in your home country. 2. Determine the optimal jurisdiction (which country's laws benefit you). 3. File first — the court that accepts jurisdiction first often has priority. 4. For contested cases, budget THB 100,000-500,000+ in Thai legal fees. 5. For uncontested mutual consent: THB 30,000-80,000 and 2-3 months at the Amphur.
