Legal cohabitation - request for information

The declaration of legal cohabitation is a legal device by which you and your cohabitant can make your cohabitation official before the Civil Status Officer of your municipality of residence.

The prior telephone information request is only required if both future legal cohabitants are not Belgian, born in Belgium, with no civil status history abroad. Otherwise, you can make an appointment directly at the counter.

  • Be 18 years old and have legal capacity
  • Not be married or in legal cohabitation with another person

The Civil Registrar shall refuse to record the declaration of legal cohabitation if he/she finds that the intention of at least one of the parties is to obtain an advantage in terms of residence or if the declaration of legal cohabitation is entered into without the consent of at least one of the legal cohabitants or if consent has been given under violence or threat.

The Civil Registrar may also postpone recording the declaration of legal cohabitation in order to carry out a further investigation. 

If the two future legal cohabitants are not Belgian, born in Belgium, with no previous civil status abroad, the service will first provide all the personalised information during a telephone appointment. The list of documents to be provided varies according to the particular situation of the future spouses (nationality, civil status, residence status,...).

You can make an appointment by phone:

You can then make an appointment at the counter of the Administrative Centre of the City of Brussels. 

ID card or residence card and/or passport
