Certificate of registration lost, then found after a duplicate request: what to do?

Verified 12 January 2026 - Public Service / Directorate of Legal and Administrative Information (Prime Minister)

If you find the certificate of registration (previously called ) after requesting a duplicate, you cannot cancel the procedure.

Once the duplicate has been requested, the production of the new registration certificate (duplicate) is launched.

The certificate of registration found (called primata) is then invalidated.

So you must destroy it.
