Drafting a Thailand prenuptial agreement
A Thailand prenuptial agreement is a written contract between fiances listing existing assets, debts, and how property will be divided if the marriage ends in divorce. Under the Civil and Commercial Code, prenups are enforceable only when registered at the same district office as the marriage, before or at registration, never after.
Thai Visa Centre coordinates marriage registration and prenup registration at amphoe for Thai-foreign couples. See marriage property guide and marriage in Thailand hub for related context.
Prenup must register at same district office as marriage.
Before or at registration. Never after under standard rules.
Typically one from each side, both aged 18 or older.
Still need 400,000 THB bank or 40,000 THB monthly income proof.
Benefits of a prenuptial agreement in Thailand
A prenup is financial planning, not a prediction of divorce.
| Benefit | Why it matters |
|---|---|
| Protect pre-marital assets | Ring-fence condo, savings, and foreign property from default equal division. |
| Clarify debt responsibility | Prevent surprise liability for spouse pre-existing loans. |
| Speed uncontested divorce | Pre-agreed division reduces amphoe or court conflict. |
| Cross-border clarity | Thai-foreign marriages often span multiple jurisdictions. |
| Family harmony | Transparent financial planning before wedding reduces future disputes. |
What cannot be included in a Thai prenup
| Allowed | Not allowed or unenforceable |
|---|---|
| Division of property and debts | Child custody arrangements contrary to child welfare |
| Alimony or spousal support terms within law | Provisions violating public order or good morals |
| Separate vs marital asset lists | Clauses forcing waiver of legally mandated child support |
| Business ownership structure | Illegal conditions |
Courts may override prenup clauses that contravene mandatory child protection or public policy.
Legal requirements for validity
- Be in writing
- Be signed by both parties
- Have two witnesses, typically one from each side, aged 18+
- Be registered at the amphoe where marriage is registered concurrently with marriage
- Be entered on the marriage register or attached as prescribed by law
Oral prenups are void. Prenups signed after marriage registration do not receive standard prenuptial treatment. Each party should have independent legal review.
Registration timing: Registration must occur concurrently with marriage registration at the same amphoe. TVC coordinates registration. Complex drafting may involve partner Thai family lawyers.

Cross-cultural and foreign asset advice
- Property abroad may require home-country enforcement through local prenup or mirror agreement.
- Condominium in foreign name: confirm sin suan tua personal property classification.
- Thai land in spouse name: prenup cannot grant foreign land ownership. Clarify contribution claims.
- Sin Sod dowry: optional clause on treatment if marriage ends.
- Long cohabitation before marriage: unregistered cohabitation assets need separate agreement.
Sin Sod dowry context: Thai dowry guide. Cohabitation without marriage: common law marriage guide.
Notarisation and international recognition
For foreign recognition: notarial certification of signatures, MFA legalisation in Thailand, and home-country apostille or authentication as required. Enforcement abroad depends on that jurisdiction conflict-of-laws rules. A Thai registered prenup is strongest in Thailand.
