Set out who owns what before you register the marriage.
A Thai prenuptial agreement for couples registering their marriage here — drafted to the Civil and Commercial Code's exacting formalities, signed and entered into the marriage register on the day, so that what you each bring in and what you build together is defined while the terms are still agreed.
In Thailand a prenuptial is enforceable only if it is registered with the marriage — get the timing wrong and it is void.
Under the Civil and Commercial Code a prenuptial agreement must be made in writing, signed by both intending spouses and at least two witnesses, and entered into the marriage register at the district office (Amphur) at the same time the marriage is registered. Miss any of those steps — sign it after the wedding, leave it off the register — and Thai law treats it as void. The agreement governs property, defining each party's separate property and the marital property the couple acquires together; it cannot dictate custody or override provisions that are contrary to public order or good morals.
We draft the agreement so its property terms are clear and enforceable under Thai law, and prepare it bilingually so each party signs something they fully understand. We then ensure it is executed and registered correctly on the day at the Amphur — the single point at which most improperly executed prenuptials fail.

Prenuptial Agreements — eligibility & documentation
What we cover
- Drafting an enforceable Thai prenuptial agreement that meets the Code's requirements — written, signed by both parties and two witnesses, and registered with the marriage at the Amphur.
- Defining separate property (Sin Suan Tua) and marital property (Sin Somros), including how assets brought into the marriage and assets acquired during it are treated.
- Advising on what Thai law can and cannot do — property only, not custody, and nothing contrary to public order or good morals.
- Bilingual Thai–English drafting, so each party signs a version they fully understand and the registered Thai text governs.
- Attending to correct execution and registration on the marriage date, and reviewing the terms against your intended division of assets before signing.
What to prepare
- Passports of both parties.
- A disclosure of assets and debts for each party — bank accounts, property, investments, shareholdings, and liabilities.
- Details of property each party brings into the marriage, with supporting documents where available — title deeds, share certificates, and valuations.
- The district office (Amphur) where you intend to register the marriage, and the planned registration date.
- Any existing prenuptial or marital-property agreement held in Thailand.
- Details of the two witnesses who will sign, and confirmation each is of age and available on the day.
