    Prenuptial Agreement (Thailand)

    Guide to drafting a legally binding prenuptial agreement in Thailand — must be registered with the marriage to be enforceable.

    Updated:
    Legal Basis: Civil and Commercial Code, Sections 1465-1469Est. Cost: THB 20,000–80,000 (lawyer drafting + registration)

    When to Use

    Before marriage registration at the Amphur. A Thai prenuptial agreement must be made before and registered together with the marriage — post-nuptial agreements are not recognized under Thai law.

    Key Clauses

    Identification of Sin Suan Tua (Personal Property)

    essential

    List all personal property each party brings into the marriage — property owned before marriage remains personal.

    Sin Somros (Marital Property) Management

    essential

    Define how community property acquired during marriage will be managed and divided if divorced.

    Income and Earnings Classification

    essential

    Specify whether income earned during marriage is personal or community property.

    Debt Allocation

    recommended

    Clarify which debts are personal and which are joint — pre-marriage debts typically remain personal.

    Property Division on Divorce

    essential

    Specify the percentage split of community property on divorce (default is 50/50).

    Inheritance Provisions

    recommended

    Outline inheritance rights and any waivers — particularly important in international marriages.

    Warnings

    A prenuptial agreement MUST be registered at the Amphur together with the marriage registration — otherwise it is void.

    Post-nuptial agreements (after marriage) are NOT recognized under Thai law.

    Both parties should have independent legal advice — one-sided agreements may be challenged.

    Clauses relating to child custody or child support cannot be pre-determined and will not be enforced.

    The agreement must be in Thai to be registered — bilingual versions are recommended.
