State or federal? The question that decides everything else

Mexico is a federation, and the authority that issued a document determines how it has to be prepared for use abroad. Civil records belong to the states. A birth, marriage or death is registered with the Registro Civil of the entity where it happened, which in this case is Mexico City itself, a federal entity in its own right since it stopped being the Distrito Federal. Because the record is a state record, the apostille that legalises it for a Hague Convention country is issued by that state's own government secretariat, not by anyone in the federal apparatus.

Federal documents take the other route. Anything signed by a federal ministry, including much of what comes out of the education system, is apostilled by the Interior Ministry, the Secretaría de Gobernación. People trip over this constantly: a family will present a birth certificate and a university degree at the same window and be told the two need different offices. If the destination country is outside the apostille convention the process is different again, running through consular legalisation rather than a single certificate.

There is a third case that surprises people, and it runs the other way. A child born abroad to Mexican parents can be registered at the nearest Mexican consulate, and the acta that results is a Mexican civil record created outside Mexico. Families who have lived in the United States for a generation often hold a mixture: a consular acta for one child, a state-issued acta for another, and American certificates for a third. Each of those was produced under different rules and each needs a different route into the other country's system, so it is worth sorting the pile by issuing authority before deciding what needs translating and in which direction.

The document you are translating has changed shape in recent years, which helps. The acta de nacimiento is now issued on a standard national layout that can be requested online, arriving as a printable sheet with a folio number and a verification code that lets any reader confirm it against the registry. That code is not something to translate. It is transcribed exactly, along with the folio, because it is the part a consular officer will actually use to check that the document is real.

The CURP quietly locks in how your name is spelled

Every person registered in Mexico has a CURP, an eighteen-character code printed on the acta and repeated on almost everything issued afterwards. It is not a random serial. It is built out of the letters of the surnames and given name, the date of birth, the sex, and the state where the person was born, with a couple of check characters on the end. That construction has a consequence people rarely notice until a file is rejected: the code encodes a particular spelling of a particular name. If a translated document quietly drops an accent or merges two surnames into one, the name no longer agrees with the code sitting three lines below it, and a reviewer comparing the two has a discrepancy to raise.

The same discipline applies to places. Mexican documents are full of toponyms that come from Nahuatl, Maya, Purépecha and other languages: Xochimilco, Tlalpan, Iztapalapa, Cuauhtémoc, Nezahualcóyotl. They look misspelled to a spellchecker and they are not. A place name is copied across unchanged, accents included, never anglicised and never regularised into something that reads more comfortably. The registry office that issued the record is identified by that name, so altering it makes the issuing office harder to trace.

Older records complicate matters in a different way. Entries from earlier decades were written into bound ledgers by hand and are reissued today as transcriptions, sometimes with faded ink or an abbreviation nobody uses any more. Those pages upload the same as any other scan, and the sensible habit is to compare the names, dates and act numbers in the output against the original rather than assuming an old document behaves like a freshly printed one.
