Foreign civil-status records: translation and apostille for naturalisation

Why civil-status records often hold up applications

A foreign record must enable the French authorities to verify your identity, parentage and family events. An accurate translation is not always enough: depending on the country and the document, an apostille or legalisation may also be required.

These formalities serve different purposes. Translation makes the text understandable; an apostille or legalisation authenticates the capacity of the signatory and the seal under the applicable system.

Start with the right record

For civil-status purposes, the authorities generally require a full copy or complete record, not a basic incomplete extract. The record must be provided in the language of the country of origin, in accordance with the application instructions.

If the record has been corrected, reconstructed or drawn up following a court judgment, include the corresponding decision where required. A discrepancy in a date, name or place must not be concealed: document its origin.

Apostille or legalisation?

The required formality depends on the issuing country, the type of record and the applicable international conventions. There are three possibilities:

• no additional formality;
• an apostille from the competent authority;
• legalisation through the prescribed chain.

Do not decide based on the language or geographical proximity. Consult the official table and the information provided by the competent embassy or consulate for the country concerned.

In what order should you proceed?

First obtain a compliant and recent record if an age limit applies. Then arrange for the apostille or legalisation of the document requiring it. Finally, send the complete set to the translator so that all relevant endorsements, stamps and formalities are translated.

The exact order may vary depending on the issuing authority. Ask for confirmation before sending an original that would be difficult to replace.

Who can translate the documents?

Every document written in a foreign language must be accompanied by a French translation that meets the official rules. Service-Public states in particular that applicants may use a certified translator or one authorised to work for the judicial or administrative authorities of an accepted European country.

Keep the original translation. Check that the translator has reproduced the names, numbers, dates, marginal notes and stamps without taking it upon themselves to “correct” them.

Dealing with differences in names and dates

Difficulties often arise from transliteration, different calendars, double-barrelled names or an old error. Draw up a table of the variants appearing on the passport, birth certificate, residence permit, parents' records and marriage certificate.

Depending on the circumstances, you may need a correction by the authority in the country of origin, a judgment, a certificate confirming that the details refer to the same person, or a documented explanation. A personal declaration alone is not always sufficient.

Costly mistakes

• translating an incomplete photocopy;
• obtaining an apostille for the wrong document;
• forgetting endorsements on the reverse;
• using a translator whose work is not accepted for the procedure;
• providing an extract when a full copy is required;
• scanning the record and its translation separately without identifying them.

Scanning checklist

Scan in colour without cutting off the edges, and make sure every stamp is legible. Name the files clearly: birth-certificate-original, apostille and french-translation. Keep the paper documents, as the authorities may ask you to present them.
