Change of first name

The Civil Status Officer can authorise the change of your first names. The procedure is reserved for Belgians. It is extended to recognised refugees and stateless persons.

The competent civil registrar is the one:

  • of the municipality where the person of Belgian nationality concerned by the change of forename is registered
  • or, failing that, the municipality of the last place of residence
  • or, failing that, the City of Brussels (if you have never been domiciled in Belgium)

The first name(s) requested cannot cause confusion and cannot harm you or others.

For a first name change for a minor, a parent or legal representative must be present.
