If you have a child whose descent is only established on the mother's side, you can have the descent of the father or the companion mother established in a deed with the Civil Registry Officer, in the municipality where the child, mother or candidate for recognition lives, or in the municipality where the child was born.
It is no longer possible to make an appointment online. The service only receives citizens by appointment.
If in doubt or for more information, please contact the Births Service without moving.
How to apply?
Both parents must be present by appointment, only at the counter of the Administrative Centre of the City of Brussels. The presence of the child is mandatory if it is older than 12 years. The mother's permission is required.
The presence of one parent is sufficient if there is a judgment for the recognition of the father or the companion without the consent of the mother.
If you want to proceed with the recognition of a child born abroad, you must make an appointment at the Foreign Certificates Service.
To make an online demand, you must complete the form and return it to the Births Service ( firstname.lastname@example.org):

Waiting period (two-step procedure)
1st step: preparation of the declaration of recognition against delivery of the aforementioned documents
- A decision is taken either immediately or within a maximum of two to five months if the request requires a thorough analysis under the law of 19 September 2017 on the fight against fraudulent recognition
- Please note: if all requested documents are not provided, the declaration of recognition cannot be made.
- Please note: there is no parentage bond if one of the parents only wants to take advantage by having a recognition certificate drawn up with regard to the stay. The decision is taken within a period of 2 months, which can be extended by 3 months by the public prosecutor.
In the event of a refusal by the civil servant, the person (who wishes to establish the parentage link) can appeal to the family court within one month after the notification of the decision. Persons whose authorization is required for the recognition are summoned to hear the case.
