The Alaska Notice to Lessor of Exercise of Option to Cancel Proprietary Lease of Cooperative Unit is a legal document that enables a lessee in a cooperative housing arrangement to exercise their right to cancel their proprietary lease agreement with the lessor. This notice serves as a formal notification to the lessor regarding the lessee's intention to terminate the lease. In cooperative housing, the lessee, also known as the shareholder, holds proprietary rights to occupy the cooperative unit rather than owning the unit outright. The cooperative unit typically refers to a residential apartment or a housing unit within a cooperative building or development. It is essential for both parties to understand the necessary steps to be taken when a lessee wishes to exercise their option to cancel their proprietary lease. This Notice to Lessor outlines important details such as the lessee's name, contact information, effective date of cancellation, and the cooperative unit's specific identifying details, including the address. It also provides an opportunity for the lessee to elaborate on the reasons for the termination and any additional information they may wish to include.
