Same-sex marriage is legally recognized and performed throughout Mexico since 2022. On 11 August 2010 the Supreme Court of Justice of the Nation ruled that same-sex marriages performed anywhere within Mexico must be recognized by the 31 states without exception, and fundamental spousal rights except for adoption (such as alimony payments, inheritance rights, and the coverage of spouses by the federal social security system) have also applied to same-sex couples across the country. Mexico was the fifth country in North America and the 33rd worldwide to allow same-sex couples to marry nationwide.
Only civil marriages are recognized by Mexican law, and all proceedings fall under state legislation.
