Certificate of nationality

This page was last modified on 28-09-2017


Unless proven otherwise, a person is generally deemed to be a Luxembourg national if they possess:

  • a valid Luxembourg passport; or
  • a valid Luxembourg ID card.

A certificate of nationality (Heimatschein) also serves as proof of Luxembourg nationality.

Luxembourg citizens are only required to produce a certificate of nationality in the following cases:

  • if the Luxembourg authorities question or dispute their status as a Luxembourg national;
  • if foreign authorities require that such a certificate be produced.

As part of the procedure for naturalisation or the recovery of Luxembourg nationality, applicants may be asked to produce a certificate of Luxembourg nationality for their spouse, parent, grandparent or child.

In addition, Luxembourg nationals residing abroad and not in possession of a valid Luxembourg passport or ID card can prove their status by producing a certificate of Luxembourg nationality.

Information included

The certificate of Luxembourg nationality attests that the named person is a Luxembourg national and has not lost this status to the best knowledge of the issuing authority.

At the request of its holder, this certificate can include the date on which Luxembourg nationality was obtained as well as the means by which it was obtained.

The certificate of Luxembourg nationality is deemed to be sufficient proof of the holder's status as a Luxembourg national until proof is provided to the contrary.

How to apply for a certificate

In order to obtain a certificate of nationality, the applicant must provide proof of Luxembourg nationality by means of documentary evidence.

A certificate of nationality may be applied for:

  • by appearing in person at the Nationality Office of the Ministry of Justice (Service de l'indigénat). If the applicant is unable to appear in person, the certificate of nationality may be requested by a trusted representative, who will be required to produce a copy of the applicant’s ID card;
  • by sending a request to the Nationality Office by post, including the applicant’s:
    • surname and given name(s);
    • date and place of birth;
    • address in Luxembourg or abroad.

Applicants must enclose a copy of their passport or ID card with the application or present this copy when they appear in person at the Nationality Office.

The same information must also be provided for any of the applicant’s children who require a certificate of Luxembourg nationality.

Document(s) to be provided

The application for a certificate of Luxembourg nationality must include:

  • the applicant’s surname and given name(s), date and place of birth, and address;
  • the surname(s) and given name(s), dates and places of birth of the applicant‘s parents;
  • the intended use of the certificate of nationality.

The Nationality Office may require that certain documents be provided, such as:

  • birth certificates;
  • marriage certificates;
  • death certificates;
  • court rulings;
  • copies of foreign identity documents.

As the documents to be provided when applying for a certificate of nationality differ depending on the individual circumstances, interested parties are encouraged to get in touch with one of the following beforehand:

  • the Nationality Office (tel.: (+352) 247 84 5 32 or (+352) 247 88 5 25); or
  • the 'Nationality' infoline at 8002 1000 (or (+352) 247 88 5 88 if calling from abroad).

Once all the necessary documentation has been received, the Nationality Office will send the certificate of Luxembourg nationality to the applicant by post as soon as possible.
