Spanish affidavit translation for USCIS, a family court, a school or an insurer, and of US affidavits into Spanish for a Mexican Registro Civil, a Colombian notaría or a Spanish consulate. There is no affidavit as such in Spanish-speaking law, so we translate the documents that do its job: the declaración jurada, the carta bajo protesta de decir verdad, the declaración extrajuicio and the acta notarial.
What stands in for an affidavit in Spanish-speaking countries
Civil-law countries have no affidavit sworn before a notary public. Each has its own written statement, and the translation names it for what it is.
Mexico: bajo protesta de decir verdad
Mexico replaced oaths with the protesta, so a Mexican statement opens or closes with the formula bajo protesta de decir verdad, which we render as under protest of telling the truth, with a note that this is the legal equivalent of a sworn statement. A plain carta is signed by the declarant and often by two witnesses; a stronger version is a fe de hechos or an acta de declaración drawn up by a notario público, who in Mexico is a licensed attorney holding a numbered notaría. USCIS sees these most often as birth affidavits from relatives when an old acta cannot be found, filed with the Registro Civil's constancia de inexistencia de registro.
Declaración jurada and declaración extrajuicio
Argentina, Peru, Chile and Spain use the declaración jurada, signed under oath and, where the recipient demands it, with the signature certified by an escribano or a notario. Colombia's declaración extrajuicio or extraproceso is made before a notaría and is the standard proof of a unión marital de hecho, of financial dependency or of a person's residence. For a USCIS file these become the statements of cohabitation and support that a spouse or a parent petition asks for, and the translation carries the notary's attestation, the escritura or acta number and the stamps as well as the statement itself.
US affidavits going the other way
A US citizen marrying in Mexico is often asked for a sworn single-status statement, since Mexico issues no national certificado de soltería and some registries want an affidavit of eligibility to marry notarized in the US, apostilled by the state and translated into Spanish. A parent whose child travels to or from Mexico without them writes a notarized consent letter that airlines and immigration officers may ask to see. Both are translated into Spanish with the notary's jurat rendered in full, and the Registro Civil may ask for a perito traductor instead, so check before ordering.
Who is asking for your Spanish affidavit translation?
The translation is the same. What changes is whether the recipient wants anything added to it.
USCIS
Affidavits standing in for a missing birth or marriage record are accepted with a complete English translation and a signed certification from the translator. No notarization is needed.
A court admits a translated affidavit with the translator's signed certification, and many ask for it notarized. Add notarization at checkout if the clerk asks for it.
Three things that save a day of back and forth on a Spanish affidavit.
01
Send the signed and notarized version
An affidavit is the sworn statement plus the notary block, stamp and seal. Upload the executed copy, with every exhibit it refers to, not the draft.
02
Give us the names as the passport spells them
The affiant, the notary and anyone named in the statement keep their names as written, with your English spelling noted, so the recipient can match the affidavit to the rest of the file.
03
Tell us where it is going
A court, USCIS and a foreign registry each want the certification handled differently. Say which in the order notes and we match the format.
Details and pricing
What is included in a Spanish affidavit translation
One price per page covers the translation and its certification. A page is up to 250 words, and the quote tells you the page count before you pay.
Everything on the affidavit is translated, including stamps, seals and handwritten notes. Tell us the English spelling you use for each name when you order.
Will USCIS accept a Mexican carta as an affidavit of birth?
USCIS asks for a birth affidavit when the civil record does not exist or cannot be obtained, and it wants it from someone with direct knowledge, usually an older relative, alongside proof from the Registro Civil that no record was found. A Mexican carta bajo protesta de decir verdad or a notarial acta serves, with a certified translation. The statement should give the declarant's own birth date, how they know the facts, and the child's full name, date and place of birth and parents.
Do you translate the notary's stamps and the escritura number?
Yes, all of it. A Colombian declaración extrajuicio carries the notaría number, the city, the notary's name and signature, a stamp and sometimes a serial sticker; a Mexican acta notarial cites the libro and the instrumento number. Those details are what tell a US reader that the statement was made before an official, so they are translated and labelled, not summarized as a notary stamp.
My affidavit is in English and was notarized here. What does Mexico or Spain need?
Usually an apostille on the notarized original from the Secretary of State of the state where it was notarized, then a Spanish translation of the whole set. Get the apostille first, so the translation covers the affidavit, the notary's jurat and the apostille together and the receiving office can follow the chain of signatures.
How much does a certified translation cost?
Certified translation is $25 per page, with a page counted as up to 250 words. Notarization, a mailed physical copy and an apostille are optional and priced separately.
How long does a certified translation take?
Standard turnaround starts at 24 hours and depends on the length and language of your documents. If you have a deadline, include it in your quote request.
