Immediately if paternity or motherhood recognition is not required.

If recognition is required, the procedure takes place in two steps:

  • 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 bond) 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.
  • 2nd step: drafting the recognition certificate

  • 1 extract from the birth certificate
  • 1 document for the child benefit (only issued once, in the event of loss you must contact the child benefit fund)
  • 1 document for the health insurance company (only provided once, in case of loss you must contact the health insurance company)
  • 1 document regarding the compulsory polio vaccination, to be completed by the doctor or during the consultation with ONE or Kind & Gezin and subsequently to be submitted to the municipality where the child lives

According to Belgian law, the parents have the option of giving their children the name of the father/companion mother, the name of the mother or a combination of the two names in the desired order.

Please note: for a first child, it is mandatory to take the Model Declaration of Name Declaration document, signed by both parents: Name choice declaration (in French).

Two or more nationalities?

Since 1 January 2018, the rules of private international law have been amended on the applicable law for establishing and changing the surname and first names of a child who has multiple nationalities. If a child has two or more nationalities, the chosen nationality is taken into account.

The choice must be formulated in the following way:

Please note: for this declaration, the parents choose the law applied to determine the name of their child, without this choice affecting the nationality of the child, which is taken into account for the stay and registration in the national register.

The determination of the first name of a child is governed by the law of the state of which the child has the nationality.

According to Belgian law, the choice of first name or given names is free, but the Civil Registry official can refuse the first name in the following cases:

  • The first name is confusing (for example, a typical girl's name for a boy or vice versa)
  • The first name can harm the child (for example, a ridiculous, absurd or offensive name)
  • The first name can harm third parties (for example, an existing family name is given as a first name to a child, although this is not common)

For more information, contact the Registry Office of your municipality.
