Reconocimiento, and thirty-two civil codes
Acknowledgment of paternity in Mexico is governed by state civil codes, so the procedure, the age at which a child's consent is required and the effects on the surname differ between Jalisco, Nuevo León and Mexico City. We name the state and the article rather than describing a national rule that does not exist.
The acknowledgment may be made in the birth registration itself, by a later appearance before the Registro Civil, by notarial instrument, or in a will. Each produces a different document and the translation names which.
The anotación marginal, and the reissued acta
A later acknowledgment is recorded as an anotación marginal on the acta de nacimiento, and a copia certificada issued afterwards shows the original entry in the body and the acknowledgment in the margin with its date and instrument.
This is where US readers go wrong: the certificate looks as though it still shows no father, because the body is the original entry. The margin is the operative text and we translate it in the margin where it sits.
The surname changes, and so does the CURP
Acknowledgment normally adds the father's surname, which in Mexico sits first — so a child registered as Ana López Hernández becomes Ana Ramírez López. The CURP is derived from the name, so a new one is issued and older documents carry the old one.
A packet therefore holds school records, vaccination cards and an older acta under one name and a CURP, and newer documents under another. That is the acknowledgment working, not a discrepancy, and the translation should let a reader see it.
Judicial paternity, and the presumption
Where the father does not acknowledge voluntarily, filiation is established by a juicio de reconocimiento de paternidad, and Mexican courts have held that an unjustified refusal of a DNA test may found a presumption of paternity. The resulting judgment is a different instrument from a voluntary acknowledgment.
A child born during marriage is presumed the husband's, and rebutting that presumption is a separate action again. We name the instrument. See our Mexican birth certificate page.
Ordering, and what the certification covers
Upload the document, choose certified translation at $24.95 per page of up to 250 words, and it comes back typically within 24 hours as a PDF formatted to mirror the original, with a signed certificate of translation accuracy on letterhead. Marginal annotations are translated in place, in the margin, and every seal, stamp and registry endorsement is translated with the text. See how we translate and certified versus standard.
Frequently asked questions
Is the procedure the same across Mexico?
No. Each state has its own civil code, and the effects on the surname and on a child's consent differ. We name the state and article.
My child's acta still shows no father in the body.
Look at the margin. A later acknowledgment is recorded as an anotación marginal and that is the operative text.
Why does my child have two CURPs?
The CURP is derived from the name, and acknowledgment adds the father's surname. Older documents keep the old CURP.
What if the father will not acknowledge?
A judicial action establishes filiation, and courts have held that refusing a DNA test may found a presumption. That judgment is a different instrument.
