Simplified surname change in France
France’s simplified surname-change procedure concerns a name derived from parentage. It is different from using a customary name or seeking a change by decree. Prepare the records establishing parentage and identify relatives whose civil records may be affected. Confirmation is a separate step from the initial request. Check current official forms and document requirements before filing.
