A Cancellation of Lease Agreement Letter is a written notification that notifies the other party in an agreement of its termination. This letter is sent by either the tenant or the landlord in order to officially end their lease agreement and vacate the rented premises. It provides necessary information such as the parties involved, the property leased, duration of the contract, and details of any financial obligations that are due. The intention of this letter is to clearly communicate the intent to end the agreement without leaving any room for misinterpretation. It serves as written evidence in case legal action is required.
