A Lease Assignment Document is a legally binding contract between a landlord and tenant which assigns the tenant’s rights and obligations in the lease to another party. This document is used when a tenant wants to transfer his or her lease agreement to someone else without getting permission from the landlord. The Lease Assignment Document outlines the terms of the lease, as well as both parties’ contact information and signature for verification. It also outlines any additional agreements that might need to be made between the tenant and the new tenant in order to ensure smooth transition with no legal complications. By signing this document, both parties agree that the new tenant will assume all of the responsibilities held by the original tenant.
