An apostille is an international certification that authenticates the origin of a public document for use in another country. Mexico and the United States are both parties to the 1961 Hague Apostille Convention, which means a Mexican apostille on a Mexican marriage certificate is recognized in the USA and Canada without further legalization. The apostille is what makes the Mexican marriage legally binding back home.
After the civil ceremony, the Mexican Registro Civil issues the marriage certificate. The certificate is then sent (by the resort’s coordinator or by your Mexican attorney) to the Secretaría de Gobernación for apostille. The apostille process currently takes 4 to 12 weeks, depending on backlog. After the apostille is issued, the certificate is translated into English by a certified translator. The final document — apostilled Mexican certificate plus certified English translation — is your legal proof of marriage in the USA or Canada.
Plan for the apostille timeline before the wedding. If you have an immigration petition, a name change, a tax filing, or an insurance enrollment that depends on the marriage certificate, the apostille delay will hold those up. Couples who need the legal proof quickly should choose Path A (civil at home) and avoid the apostille timeline entirely.
