In Mexico, domestic relations—covering marriage, divorce, parental rights, adoption, and family property regimes—are governed primarily by state civil codes, though federal constitutional principles also apply. Foreigners may marry in Mexico under the same substantive requirements as Mexican citizens, including presenting identification, proof of legal capacity, and, when applicable, apostilled or legalized foreign documents. Marriages celebrated abroad are generally recognized in Mexico as long as they comply with the laws of the place where they were performed, and foreigners may choose between marital property regimes such as community property or separation of assets.

Regarding divorce and parental matters, foreigners have access to Mexican family courts when the marital domicile, the children’s habitual residence, or the effects of the marriage are located in Mexico. Mexican law recognizes both administrative and judicial divorce, though foreigners typically proceed through judicial channels when minors, property disputes, or international elements are involved. Custody, visitation, and child‑support decisions are guided by the best‑interest‑of‑the‑child standard, and Mexico is a party to the Hague Convention on International Child Abduction, which governs cross‑border custody conflicts involving foreign nationals.

Foreigners may also adopt in Mexico, but the process is highly regulated and varies by state. Prospective adoptive parents must meet eligibility requirements, undergo psychosocial evaluations, and work through accredited public or private institutions. International adoptions require compliance with both Mexican law and the Hague Adoption Convention, ensuring safeguards for the child and coordination between authorities in both countries. Overall, Mexico’s domestic‑relations framework provides foreigners with access to family‑law institutions while maintaining strong protections for children, family stability, and public policy considerations.
