A person seeking to make a declaration to acquire or recover Belgian nationality must satisfy various requirements and follow a standard procedure, as follows:
Residence period The person is required to have had their
main residence in Belgium for the prescribed period on a legal and uninterrupted basis. This condition can be satisfied by having continuously held an
identity card of type A, B, C, D, EU/EU+, F/F+, H or M, or a series of these cards. Additionally,
EU citizens benefit from a "declarative" right of residence, and can therefore count their legal residence as beginning from the day they first registered at their municipality, rather than the day on which they were first issued their identity card, which could be weeks or months later. For example, in the case of a holder of an E card, the person may count the period during which they held an "Annexe 19" indicating they had requested an E card. During the prescribed residence period, the person cannot have been absent from Belgium for more than six consecutive months OR one fifth of the total period.
Right to permanent residence The person is also required, as at the time of the declaration, to hold the right to continue residing in Belgium indefinitely. This condition can be satisfied by producing an
identity card of type B, C, K, L, EU/EU+, F/F+ or M. Identity cards of type A or H are not valid as they provide only a temporary right of residence.
Declaration text The person is required to sign a statement, which includes the following text
written out by hand: “I declare my desire to acquire the Belgian nationality and to submit myself to the
Constitution, the
laws of Belgium, and to the
Convention for the Protection of Human Rights and Fundamental Freedoms.” (
“Je déclare vouloir acquérir la nationalité belge et me soumettre à la Constitution, aux lois du peuple belge et à la Convention de sauvegarde des droits de l’homme et des libertés fondamentales.” / "Ik verklaar Belgisch staatsburger te willen worden en de Grondwet, de wetten van het Belgische volk en het Verdrag tot bescherming van de rechten van de mens en de fundamentele vrijheden te zullen naleven.")
Other requirements A
birth certificate is almost always required, except in a few limited scenarios where it would be impossible to obtain one. The birth certificate must be
legalised in the country of origin (unless there is an
international treaty in place), and a
sworn translation into one of the
national languages must be appended (unless the document is already in one of these languages). Depending on the selected route, the person may be required to satisfy a language requirement and/or prove other types of social/economic integration. For a recovery declaration, the person does not need to satisfy any language or integration requirements. Most declarations require payment of a fee of €1000. However, for a recovery declaration, there is no fee (i.e. the procedure is free). Some municipalities levy additional taxes/fees, such as a €50 fee in Brussels.
Procedure Nationality declarations must be submitted at the registrar in the person's
municipality in Belgium. The registrar is only responsible for collating the required documents and is not responsible for approving the declaration. The declaration file is then transferred to the King's Prosecutor (also known as the Crown Prosecutor) (
Procureur du Roi / Procureur des Konings) for review, which lasts up to four months. The prosecutor will check that the person satisfies the criteria, as well as whether there are any serious negative facts (
faits personnels graves / gewichtige feiten eigen) that would preclude the person from being accorded Belgian nationality (such as a criminal record or terrorist links). If the prosecutor issues a positive decision or does not issue a decision within the allocated time period of four months, the person becomes a Belgian citizen. The municipal registrar draws up a corresponding act (
acte de nationalité belge / akte van Belgische nationaliteit) and updates the person's record in the
National Register. The person concerned is then invited to apply for a
Belgian citizens' identity card. The names of new citizens are periodically published in the
Belgian official journal (
Moniteur belge / Belgisch Staatsblad). If the prosecutor issues a negative decision, the person concerned is notified and given the opportunity to appeal the decision through the courts. ==Dual citizenship==
