Offices that take your departure report in Belgium

Have your current residence card, national-register number, details of family members leaving with you, email, phone, overseas address and departure date ready. Keep a copy of the card: Model 8 and appendix 37 alone do not prove prior lawful residence at border checks. If a declared temporary absence becomes permanent, submit the form again with permanent departure selected.

Prepare identity cards for everyone included, names, old address, departure date and foreign address; if unknown, at least the destination country and city. Keep the acknowledgement and reference number. Moving abroad does not automatically dissolve legal cohabitation. If you have already left, contact the department to resolve your registration rather than assuming a retrospective declaration is possible.
