Same-sex marriage in Thailand: the practical guide.

The Civil and Commercial Code Amendment Act (No. 24), B.E. 2567 (2024) was published in the Royal Gazette on 24 September 2024 and, under its own transitional clause, took effect 180 days later — 23 January 2025. Thailand was the first country in Southeast Asia, and the third in Asia after Taiwan and Nepal, to legislate full marriage equality. The Act works by replacing gendered terms — "man and woman", "husband and wife" — with gender-neutral "individuals" and "spouses" across more than 60 sections of the Civil and Commercial Code's family-law book, rather than by creating a separate, parallel civil-union status.

Yes, on the same terms as an opposite-sex marriage. A foreign spouse — of either gender — married to a Thai national can apply for the Non-Immigrant O visa on the grounds of marriage to a Thai national, and extend it annually at Thai immigration by meeting the same financial requirements applied to any marriage-based extension (commonly cited as 400,000 baht seasoned in a Thai bank account, or a monthly income around 40,000 baht, though exact figures and evidentiary rules are set by immigration order and should be confirmed at the local office before applying). The Marriage Equality Act's gender-neutral drafting means immigration's marriage-visa category no longer excludes a marriage on the basis of the spouses' sex — what it has never excluded is the underlying financial and documentary bar, which is unchanged.

The Marriage Equality Act changes family law, not property law for foreigners — and those are separate statutes. A foreign spouse still cannot own land in Thailand in their own name, regardless of their spouse's nationality or the couple's genders; that restriction comes from the Land Code, not the Civil and Commercial Code. A Thai spouse buying land while married to a foreigner has long been required to sign a Land Department declaration stating the purchase money is their own separate property (sin suan tua), not marital property — a 1999 Ministry of Interior instruction drafted in gender-neutral terms ("a Thai national married to a foreigner") that, on its face, applies the same way to a same-sex marriage, though we could not find a Land Department circular explicitly confirming this in writing since the 2025 law took effect, so confirm current practice at the local Land Office. Condominiums are more accessible: a foreign spouse can buy a condo unit in their own name exactly as any foreigner can, subject to the building's 49% foreign-ownership quota — marriage does not lift or tighten that quota either way.

This is where the Act's effect is most direct. Once married under Thai law, a same-sex spouse becomes a statutory heir on exactly the same footing as an opposite-sex spouse under the Civil and Commercial Code's succession provisions (sections 1599 onward), inheriting from a deceased spouse's estate without needing a will to establish the relationship, and gaining the marital co-ownership rights over property acquired during the marriage that flow from being legally married at all. Before the Act, a same-sex partner — however long the relationship — had no automatic inheritance standing and depended entirely on a validly drafted will. A will is still strongly advisable for anyone with property in Thailand, married or not, because it controls distribution far more precisely than the statutory default; see our Thai wills & inheritance guide.

The Act extends adoption and parental-rights provisions in the Civil and Commercial Code to married same-sex couples on the same terms as married opposite-sex couples, since it rewrote the underlying gendered language throughout the family-law book rather than adding a narrower same-sex-specific clause. Practitioner summaries describe the coverage as comprehensive, though adoption itself remains a separate court process with its own requirements regardless of the parents' marriage. Confirm current procedure with a Thai family lawyer if this applies to you.

No — and this is a real, current gap, not an oversight on this page. Marriage equality and legal gender recognition are two different pieces of legislation. As of this writing, Thailand still has no law allowing a person to change the gender marker on their national ID card or passport; a Gender Recognition Bill has been advocated for years but has not passed.
