Document background
The Lease Extension Addendum is a crucial document used when parties to an existing lease agreement wish to extend their contractual relationship beyond the original term. Under Belgian law, this document serves as a formal modification to the original lease, requiring careful consideration of federal civil code requirements and regional regulations specific to Brussels, Flanders, or Wallonia. The addendum typically includes the extension duration, any rent adjustments (including indexation), and confirmation of continuing terms. It must be properly executed and registered in accordance with Belgian law, making it particularly important for both residential and commercial property relationships. The document should be prepared when the original lease is approaching its end date and parties wish to continue their landlord-tenant relationship without negotiating an entirely new lease.
