Landlord Tenant Amendment Law and Legal Definition

Once a lease has been signed, you can usually change its terms only if the landlord and tenant agree and sign a written amendment. The amendment, together with the lease, then constitutes the final, complete and exclusive statement of the agreement between the parties regarding the subject matter and supersedes any and all prior and contemporaneous understandings or agreements of the parties.

The amendment usually provides that it may be supplemented, amended or modified only by the mutual agreement of the parties by stating that no supplement, modification or amendment of the amendment shall be binding unless it is in writing and signed by both parties. A common amendment to a lease is a change in rent.
