An Addendum To Lease Agreement is a crucial document used when parties need to modify an existing lease without creating an entirely new agreement. Under Swiss law, this document must comply with strict tenancy regulations, including the Swiss Code of Obligations and cantonal requirements. It's commonly used when circumstances require changes to original lease terms, such as rent adjustments, lease extensions, or modifications to property use. The addendum must precisely reference the original lease and clearly state which terms are being modified while confirming which original terms remain in effect. This document type is essential for both residential and commercial properties in Switzerland, requiring careful drafting to ensure enforceability and protection of both landlord and tenant rights.
