In Luxembourg, certain people are allowed to legally change their first name or surname, provided they meet a series of conditions. An application to do so must be filed with the Minister of Justice (Ministre de la Justice), who will decide on whether or not to grant the name change.
The procedure for changing a first name or surname is open to anyone:
Any person who has obtained Luxembourg nationality through naturalisation, by option or by reclaiming their Luxembourg nationality may also apply to change their first name(s) and/or surname.
Persons of foreign nationality, resident or born in Luxembourg, who wish to change their first name(s) or surname, must contact the competent authorities in their country of origin.
The procedure for changing a first name or surname is free of charge.
The request can be made:
The forms and links to the online procedure are available in the 'Forms / Online services' section.

The Minister of Justice may order the applicant to attend an interview with a person appointed as the Minister's representative.
The Minister of Justice will decide whether or not to authorise the change of first name or surname. If the authorisation is granted, a copy of the ministerial decree authorising the name change is given to the applicant.
