Declaration of marriage

The procedure :

To get married in the Brussels region, a specific administrative process must be followed. The future spouses must first go together, by appointment, to the civil registry office of the local authority in their place of residence, to declare their intention to marry. Following this declaration, a check is made of their administrative situation to establish the necessary documents, which vary according to the circumstances of each couple. The Civil Status Department is responsible for compiling all civil status documents drawn up in Belgium. However, in the case of foreign documents, the future spouses must obtain the required documents themselves.


Once all the documents have been collected, the future spouses must go together, or with a legalised proxy of the absent person, to the civil status office, after making an appointment, in order to compile the file and proceed with the marriage declaration. The date for the marriage ceremony is set as soon as the marriage declaration has been accepted. The cost of the ceremony may vary depending on the commune and the services chosen. It is also important to allow for the cost of administrative formalities, such as application fees and stamp duty.


The deadline for opening the marriage file is a minimum of two months before the desired date of celebration, and a maximum of six months, as the documents making up the marriage file and declaration of marriage are only valid for six months.


What documents should I enclose?

The documents required to open a marriage file vary depending on the commune. As a general rule, you should bring


  • the identity cards or passports of the future spouses
  • The list of documents to be provided by the registry office (nationality, marital status, residence status, etc.)
