Everything about rent
-
Indexation can take place once a year, on the anniversary date of the lease. The landlord must request it in writing. It is not automatic.
-
Service charges are paid by the tenant. They can be billed as provisions (with annual settlement) or as a flat rate (fixed amount). The lease must specify the method.
-
The recommended procedure is 3 steps: friendly reminder, formal notice by registered letter, then proceedings before the justice of the peace.
-
No, the Brussels rent grid is indicative. It gives a reference rent based on property characteristics, but the landlord is not required to follow it.
