Birth certificate apostille for Mexico
A U.S. birth certificate used in Mexico — for dual citizenship registration, Mexican temporary or permanent residency, property purchase, or inheritance — needs a California Secretary of State apostille. Mexico has been a Hague Convention member since 1995, so the apostille is all the authentication required from the U.S. side.
Mexico joined the Hague Apostille Convention in 1995. For a California-issued birth certificate used in Mexico, the California Secretary of State issues the apostille. No Mexican consulate or U.S. Embassy authentication is required after the apostille. Note: Mexico typically requires a certified Spanish translation by a Mexican “perito traductor” — we do not provide translation but note where it is required.
What this page covers
U.S.-born children of Mexican parents can register as Mexican citizens at the Mexican Consulate General in Los Angeles — but the Mexican Registro Civil and the Secretaría de Relaciones Exteriores (SRE) require an apostilled U.S. birth certificate as the foundational identity document. The same apostilled birth certificate is used for Mexican residency (Residente Temporal or Permanente through the Instituto Nacional de Migración / INM), for notarized property purchase documents (escritura pública), and for inheritance proceedings before a Mexican notario público. We handle the California Secretary of State apostille and advise on whether a Spanish translation by a Mexican perito traductor is required for your specific purpose.
Common reasons people need this
U.S.-born children of Mexican parents can obtain Mexican nationality by descent. The Mexican Consulate or Registro Civil requires an apostilled U.S. birth certificate to establish the lineage and register the child as a Mexican citizen.
INM (Instituto Nacional de Migración) requires an apostilled birth certificate as part of the residency application package for retirees, remote workers, and family reunification residency in Mexico.
When a U.S. citizen purchases real property in Mexico, the Mexican notario público requires an apostilled birth certificate (or passport-equivalent identity document) to execute the escritura pública and complete the title transfer.
U.S.-based heirs of Mexican estates must often submit an apostilled U.S. birth certificate to prove their identity and relationship to the deceased to the Mexican notario público or family court handling the succession.
How it works
Send us a photo of your birth certificate. We confirm it is the correct long-form certified copy from California CDPH or the county recorder — not a hospital record or short form — and confirm the apostille is the only U.S.-side step required for your Mexican purpose.
Mail the certified birth certificate to us (or meet in Los Angeles County). We prepare the California Secretary of State apostille submission and track the order through processing.
The California Secretary of State attaches the apostille. We ship the apostilled document to you or your Mexican notario público. If a Spanish translation by a Mexican perito traductor is required, arrange that in Mexico after receiving the apostilled original.

Birth Certificate Apostille FAQ — Mexico Use
Yes. Mexico joined the Hague Apostille Convention in 1995. A California Secretary of State apostille is the correct and sufficient U.S.-side authentication for a California-issued birth certificate used in Mexico. No additional authentication from the Mexican Consulate or U.S. Embassy is required.
Yes, typically. Mexico requires that foreign-language documents be accompanied by a certified Spanish translation by a Mexican perito traductor (court-certified translator) before use at Registro Civil, INM, or Mexican notary offices. We handle the apostille in Los Angeles; you arrange the Spanish translation in Mexico after receiving the apostilled original.
Yes. U.S.-born children of Mexican nationals can register as Mexican citizens through the Mexican Consulate General in Los Angeles or directly at the Registro Civil in Mexico. The consulate typically requires an apostilled California birth certificate, both parents’ Mexican identity documents, and may require a Spanish translation. Contact the consulate for their current document checklist.
A Mexican notario público (public notary) typically requires identity documentation — most often your passport — for a property purchase. Some notarios also accept or require an apostilled birth certificate as a supplementary identity document, especially if you are purchasing in a restricted zone (coastal or border areas). Confirm with your Mexican notario what they specifically need.
If your birth certificate was issued in Texas, the apostille must come from the Texas Secretary of State, not California. We can advise on the correct out-of-state apostille office and assist you in coordinating the process by mail.
The apostille itself does not expire. However, some Mexican government offices and notarios prefer recently issued certified copies — particularly INM, which may require a certified copy issued within six months. Check with the receiving Mexican authority on their recency requirements before ordering a new certified copy.
