French affidavit translation for USCIS, a US court or an office abroad. France has no affidavit in the US sense, so what you hold is usually an attestation de témoin under article 202 of the Code de procédure civile, a déclaration sur l'honneur, or an acte de notoriété drawn up by a notaire; Québec and Haiti do have the déclaration sous serment. We translate each into certified English, and US affidavits into French.
The documents that do an affidavit's job differ by country, and the translation has to say what each one is rather than stamp affidavit on all of them.
The attestation de témoin and its formula
A witness statement for a French court is written by hand by the witness, under article 202 of the Code de procédure civile, and must end with the line "Je sais que cette attestation sera produite en justice et que toute fausse déclaration de ma part m'expose à des sanctions pénales", followed by the date, the signature and an ID copy. There is no oath and no notary; the formula and the handwriting are what give it weight. Relatives in France often use the same Cerfa form 11527 for a supporting letter in a USCIS file. We translate the formula in full, note that the original is handwritten, and include the ID copy.
Déclaration sur l'honneur, acte de notoriété, légalisation de signature
Administrative files take a déclaration sur l'honneur, a plain signed statement with no witness at all. For stronger proof a notaire draws up an acte de notoriété from witnesses' statements: after a death to list the heirs, or when a birth record cannot be produced for a marriage. A mairie will also certify a signature, the légalisation de signature, which confirms identity and not contents, and the translation keeps that limit visible. In Senegal or Côte d'Ivoire the légalisation is done at the mairie or the commissariat.
Québec and Haiti, where the déclaration sous serment exists
Québec law provides for the affidavit outright: a déclaration sous serment, often headed affidavit, sworn before a commissaire à l'assermentation, a notaire or an avocat, with the jurat "Déclaré sous serment devant moi à Montréal le" and the commissioner's number. Haitian notaires and juges de paix take sworn declarations too, and Haitian USCIS files often include a déclaration from the tribunal de paix establishing a birth or a relationship. Each is translated with the oath clause, the official's title and the seal rendered, so a US reader can see who administered the oath.
Who is asking for your French 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 French 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 French 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.
Can I use your translation of a US affidavit in France?
Not for a court, a préfecture or a mairie, which take French translations only from a traducteur assermenté, and we are not sworn in France. The usual case is marriage: the mairie asks a US citizen for a certificat de célibat and a certificat de coutume, and most bring a notarized, apostilled affidavit of marital status in their place. Our English to French translation is for the fiancé, the family and the lawyer reading the file, not for the mairie's copy.
My relative in France signed an attestation sur l'honneur that was never notarized. Can USCIS use it?
Yes, as a statement from a third party. USCIS decides the weight, and a statement is stronger when it gives the writer's full name, address, relationship and how they know the facts, with a copy of their ID. A légalisation de signature at the mairie adds a confirmation of identity and costs nothing. We translate the statement, any mairie stamp and the ID, and our certification covers the translation.
The Haitian document is an acte de notoriété or a déclaration tardive, not an affidavit. Do you still translate it?
Yes, and we translate it under its own name. A Haitian acte de notoriété from the tribunal de paix records what witnesses declared about a birth, a marriage or a death that was never registered, and a déclaration tardive is the late registration a court then orders. USCIS sees these constantly in Haitian cases. The translation names the juge de paix, the witnesses and the date, and keeps the document's title so the officer knows it is not the civil record itself.
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.
