Luxembourg ancestry certificate

This page was last modified on 28-09-2017


As part of the procedure to regain Luxembourg nationality, applicants must prove that they are in a direct line of descent from an ancestor who was a Luxembourg national on 1 January 1900.

Among the items required to prove this status, applicants must submit a Luxembourg ancestry certificate to the civil registrar of:

  • their usual commune of residence if they live in Luxembourg;
  • Luxembourg City, if they live abroad.

The Luxembourg ancestor in question may be either male or female, and may have been either over or under the age of majority on 1 January 1900.

Information included

The certificate states that the applicant has an ancestor who was a Luxembourg national on 1 January 1900.

How to apply for a certificate

Interested parties can apply for an ancestry certificate:

  • 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 Luxembourg ancestry certificate may be requested by a trusted representative, who will be required to produce a copy of the applicant’s identity document;
  • by sending their application to the Nationality Office by post, including the following details:
    • surname and given name(s);
    • date and place of birth;
    • address in Luxembourg or abroad.

Document(s) to be provided

The following documents must be enclosed with the application:

  • a copy of the applicant’s passport or ID card if the application is submitted by post;
  • civil status certificates proving that the applicant has an ancestor who was a Luxembourg national on 1January 1900, such as:
    • a birth certificate;
    • a marriage certificate;
    • a death certificate.

The applicant may trace ancestry back to any previous generation of either the paternal or maternal line to establish that they are a descendant of the ancestor in question.

The Nationality Office may request other official documents, in particular to prove that one of the applicant’s ancestors had not lost their Luxembourg nationality before 1 January 1900.

The applicant must obtain the required documents from the relevant Luxembourg communes or foreign authorities.

If other family members subsequently wish to regain their Luxembourg nationality, the documents provided by the first applicant need not be submitted again.

Further information may be obtained before submitting the application or appearing in personfrom:
  • the Nationality Office (tel.: (+352) 247 84 5 32 or (+352) 247 88 5 25);
  • the 'Nationality' infoline at 8002 1000 (or (+352) 247 88 5 88 if calling from abroad).

Issue fee

Luxembourg ancestry certificates are issued free of charge.

However, the issuance of certain documents to be submitted as part of the procedure to regain nationality may entail charges, the amount of which is set by the issuing authority. For example, Luxembourg communes and foreign authorities may require the payment of fees for preparing copies or extracts of civil status certificates.


Once all the necessary documents have been received, the Nationality Office will send the Luxembourg ancestry certificate to the applicant by post as soon as possible.
