🇹🇭🇯🇵 Thai–Japanese Divorce
Civil law · Minpō (Civil Code) §763–§771
Quick Answer
Thai-Japanese divorce: Kyōgi rikon (mutual consent) simplest — sign rikon todoke and file at ward office in 1 day. Big issue: Japan grants sole custody only (until April 2026 optional joint reform) — Thai fathers often lose access. Hague 1980 in force for Japan since 2014.
- Uncontested: 1–3 (kyōgi rikon) months
- Contested: 18–36 (mandatory chōtei mediation first) months
- Fees: THB 85,000–420,000
- Waiting period: 0 (kyōgi rikon) · 6 (mediated chōtei) · 12+ (contested saiban)
- Hague Abduction 1980: ✓ Member
- Fault-based: No (no-fault)
Jurisdiction & Recognition
Competent court: Thai court OR Kateisaibansho (Family Court) — plaintiff's residence.
Recognition of Thai judgment in Thai–Japanese: Kyōgi rikon (協議離婚 mutual consent) via koseki filing at ward office; Thai judgment recognized via Hōrei §22 if reciprocity + due process. Register at Japanese Embassy Bangkok or ward office (yakusho).
Matrimonial Regime
System: Separation of property (§762) default; equitable distribution on divorce (zaisan bunyo §768)
Conflict with Thai law: Zaisan bunyo (財産分与) typically 50/50 of marital assets but excludes gifts/inheritance; Thai §1474 similar but calculation differs on retirement lump sums.
Spousal support: Iryōhi (慰謝料) if fault-based; monthly maintenance rare; lump-sum settlement common
Child support: Yōikuhi santei-hyō (養育費算定表) income/age tables
Child Custody
Standard: Sole custody (shinken 親権) still default — Japan does NOT grant joint custody (April 2026 law reform to introduce optional joint custody)
Hague Abduction 1980: Member — return order within 6 weeks
Insider Playbook
- Kyōgi rikon — sign rikon todoke with 2 witnesses, file at shiyakusho — 0 JPY fee
- If Japanese spouse won't sign = mandatory chōtei mediation before saiban rikon can be filed
- Child custody: Japan strictly sole shinken — non-Japanese fathers often get only menkai kōryū (visitation)
- Kōseki auto-updates after rikon todoke; Thai amphoe must be filed separately
- Company pension split via nenkin bunkatsu seido — file within 2 years
- Spouse of Japanese national visa expires 6 months post-divorce — switch to teijūsha if raising Japanese child
- Hague 1980 Central Authority (MOFA Japan) — do not remove child from Japan without consent
⚠️ Common Pitfalls
- Signing rikon todoke without understanding custody assignment = irreversible after filing
- Thai father removing child to Thailand = Hague abduction; Thai court must return within 6 weeks
- Missing 2-year nenkin bunkatsu window = permanent pension forfeiture
FAQ
- Must I travel to Japan to sign?
- No — sign rikon todoke at Japanese Embassy Bangkok; but 2 witnesses need Japanese inkan if filing at ward office
- Custody of half-Japanese child?
- Pre-Apr 2026: sole custody only — Japanese courts award mother in 80%. Post-Apr 2026: optional joint custody via mediation
- When does spouse visa expire?
- 6 months post-divorce registration; can switch to teijūsha if raising Japanese child
- How are Japanese assets split?
- Zaisan bunyo 50/50 default for marital property; mortgaged home calculated on equity after debt

Frequently asked questions
- How does a foreigner register a marriage in Thailand?
- The foreign partner first obtains an affidavit of freedom to marry from their embassy in Thailand, has it translated into Thai and legalized by the Department of Consular Affairs, and then both parties register the marriage at any district office (amphoe) with passports and two witnesses. Since the Marriage Equality Act took effect on 23 January 2025, same-sex couples register on exactly the same basis.
- Do we need an interpreter at the district office?
- Yes in practice — most district offices require that a foreign party who does not read Thai be assisted by an interpreter, and many request that the interpreter present identification and sign the register. Some offices also expect a prenuptial agreement, if any, to be presented before registration, because a prenuptial agreement in Thailand is only valid when registered together with the marriage.
- Is a Thai marriage recognized in my home country?
- A marriage registered at a Thai district office is generally valid worldwide, but recognition procedures differ: many countries want the Thai marriage certificate and the Kor Ror 2 extract translated, legalized by the MFA and certified by their embassy before it is entered in their civil register. Some countries additionally require registration with their consulate within a set period.
- How is a prenuptial agreement made enforceable in Thailand?
- Under the Civil and Commercial Code a prenuptial agreement must be in writing, signed by both spouses and two witnesses, and registered with the marriage at the district office on the day of registration — an agreement signed afterwards is void as to property arrangements. It also cannot contradict public order or the rules on parental duties, so the drafting must be Thailand-specific rather than a translated foreign template.
