Prenuptial Agreements — Enforceability Conditions under Section 1465 CCC
Spouse Seeking Enforcement v Spouse Seeking Annulment of Prenup
Composite summary — not a single reported case. This entry distils a settled line of Thai Supreme Court (Dika / ฎีกา) authority for legal education. It is not a transcript of one reported judgment, and the heading is not a citable case number. Do not cite it as specific case law — consult a Thai-qualified lawyer for the authoritative Dika number and current application.
Facts
A couple signed a prenuptial agreement before marriage, seeking to vary the default sin somros/sin suan tua regime. In disputed cases, the agreement was: (i) signed but not registered at the District Office at the time of marriage registration; (ii) drafted only in one language without translation; (iii) signed under pressure; or (iv) sought to override mandatory CCC provisions (e.g. waive maintenance rights).
Legal Issue
Under what conditions a Thai prenuptial agreement is valid and enforceable, and what defects render it void or unenforceable.
Holding
The Supreme Court has confirmed that for a prenuptial agreement to be enforceable under Section 1465 CCC, it must be: (i) made in writing, signed by both spouses and at least two witnesses; (ii) recorded in the marriage register simultaneously with marriage registration at the District Office; (iii) not contrary to public order or good morals; and (iv) not seeking to override the mandatory provisions of Thai family law (e.g. duties of fidelity, maintenance of children). Failure of registration is fatal; informal post-marriage agreements purporting to be prenups are void.
Reasoning
Section 1465 expressly requires registration. Section 1466 prohibits later amendment except by court order. The strict formalities exist because the agreement affects third parties (creditors, the Land Office) and family rights. Substantive limits reflect the worker- and child-protective purposes of family law.
Significance
Critical for mixed-nationality couples and any couple with significant pre-marital assets, business interests, or family wealth.
Practical Takeaway
Sign the prenuptial agreement BEFORE the registrar at the District Office on the same day as marriage registration, with two witnesses, and have it noted in the marriage register. A 'prenup' signed at the wedding venue or notary alone is worthless if not registered.
