Do I need a birth certificate translated into French for CAF request?

The CAF may ask for your birth certificate, depending on your situation. It is not always requested, but having it ready avoids delays.

If your birth certificate is not in French, the CAF may ask for a translation by a sworn translator (traducteur assermenté). If your certificate was issued in an EU country, a multilingual standard form issued with it may be accepted instead of a translation. Check with your CAF before paying for a translation.
