Rights and Duties Under Thailand’s Marriage-Equality Law

What Did the Marriage-Equality Law Change?

The amendment replaced key sex-specific terms such as “man and woman” or “husband and wife” with inclusive terms referring to “two persons” and “spouses.” Married couples therefore have status, rights, and duties under the Civil and Commercial Code regardless of the sex of either spouse. The changes extend across engagement, marriage, marital property, maintenance, inheritance, divorce, and related family status.

Important Rights and Duties

• Property and debt: The same statutory rules on personal property, marital property, and liability apply to all married couples.
• Inheritance: A spouse is a statutory heir under the order set by law. A will can still make individual wishes clearer.
• Decisions and official records: Marital status can support rights and duties across many systems, although agencies may require different documents and procedures.
• Divorce and family protection: Spouses use the same family-law grounds and procedures, including case-specific rules on property division and maintenance.

Children and Assisted Reproduction

Marriage equality expands legal spousal status, but it does not automatically resolve every question about legal parenthood, joint adoption, or assisted reproduction in every situation. Rights may depend on separate statutes, administrative procedures, and the family’s circumstances. Couples planning adoption or assisted reproduction should check current guidance from the responsible agency or obtain specialist family-law advice.

Employment Benefits, Tax, and Welfare

Spousal status allows a person to apply for benefits linked by law or policy to the term “spouse.” Actual eligibility may still depend on tax legislation, welfare rules, employer policies, insurance contracts, and the timing of administrative updates. It is therefore unsafe to assume that every benefit changed in exactly the same way on the first day of implementation. Confirm the rules with each relevant agency or provider.

Registering a Marriage or Using Spousal Rights

1. Confirm eligibility and required documents with the district office where the marriage will be registered.
2. Keep copies of the marriage certificate and update relevant records with agencies, employers, banks, or insurers.
3. Seek legal advice for cross-border assets, parenthood, inheritance planning, or a complex dispute.

This is a general overview, not advice for an individual legal matter. Rights and procedures can vary with the facts and with legislation governing a specific benefit.
