Document background
An Addendum To Lease Agreement is a formal document used to modify or supplement an existing lease agreement under Belgian law. It is essential when parties need to change specific terms of their original lease while keeping other provisions intact. The document must comply with the Belgian Civil Code and regional regulations (Brussels-Capital, Flanders, or Wallonia), particularly regarding residential leases which have been regionalized since 2018. Common modifications include rent adjustments, lease term extensions, changes to permitted use, or updates to party information. The addendum requires official registration with Belgian authorities and must be drafted in accordance with local language requirements depending on the region. It serves as a legally binding extension of the original lease, ensuring all modifications are properly documented and enforceable.
