Registering the birth of a child

All births must be declared to the civil registrar of the commune where the birth took place within 10 days of the birth (the day of the birth itself does not count). If the last day of this time falls on a Saturday, a Sunday or a public holiday, the time is extended to the next working day.

Please note: if no declaration is made within this time frame, a court decision will be taken to establish the birth certificate.

Who is concerned

The birth of the child must be declared:

  • by the father or mother; or
  • failing that, by the doctor, midwife or any other person who attended the birth (upon presentation of the 'notice of birth' issued by the doctor or midwife).

The father who carries out the procedures for declaring the child with the various administrations is entitled to extraordinary leave for:

  • 10 days for private-sector employees;
  • 10 days for civil servants.

The mother does not have the right to extraordinary leave, given that she already benefits from maternity leave.

How to proceed

Declaration to the commune where the birth took place

Items to present when declaring the birth:

  • Married parents:
    • the birth notice issued by the doctor or midwife;
    • family record book or, failing that, a marriage certificate;
    • ID document for the declarant and the mother.
  • Unmarried parents:
    • the birth notice issued by the doctor or midwife;
    • ID document for both parents;
    • if one of the parents has the Luxembourg nationality or was born in Luxembourg: a declaration signed by both parents stating the name that will be given to the child.

For more information, see the 'Choosing a child's first name and surname' information page.


Parents who do not reside in Luxembourg must declare the child's birth to the communal administration in the commune where it was born, as is the case for parents residing in Luxembourg.

It is important that parents find out from their country of residence what steps they need to take to ensure that the Luxembourg birth certificate is recognised in their country.

Non-Luxembourg nationals

Non-Luxembourgish parents must first declare the child to the commune, then to their consulate or embassy.

Administrative procedures pertaining to the declaration of the newborn child

The birth registration office will provide the declarant with 8 copies of the birth certificate , of which one copy must be given to:

and possibly:

  • the Medical-Surgical Fund (Caisse médico-chirurgicale);
  • the insurance company (life insurance);
  • the Housing Aid Service (Service des aides au logement) of the Housing Ministry (Ministère du Logement) if the interested party receives housing benefit);
  • the embassy or consulate of the country of origin in Luxembourg (for non-Luxembourg nationals).

In addition to birth certificate extracts, the following forms, which must be sent to the institutions whose address appears on the application, are provided to the declarant:

  • application for family allowance and birth allowance;
  • application for 'Baby-Year' (24-month deposit for pension insurance).
