Document background
The Rental Extension Agreement is a critical document used in Belgian property law when parties wish to extend an existing lease beyond its original termination date. This document type is essential for both residential and commercial properties across Belgium's three regions (Brussels-Capital, Flanders, and Wallonia), each having specific regulatory requirements. The agreement typically includes the extension period, any rent adjustments, confirmation of existing terms, and any modifications to the original lease terms. It must comply with Belgian civil code requirements and regional housing regulations, including mandatory registration with local authorities. This document is particularly important as it provides legal certainty while avoiding the need to draft an entirely new lease agreement. The Rental Extension Agreement must include specific elements required by Belgian law, such as energy performance certificates and explicit references to the original lease terms.
