The California Confirmation of Lease is a document used for verifying the terms of a lease between a landlord and tenant. It is also sometimes referred to as a lease confirmation letter. It is a legally binding document that can be used as evidence in case of a dispute between the parties. This document is required by law in California and must be signed by both the landlord and tenant. It must include the names of both the landlord and the tenant, the address of the rental property, the length of the lease, and the amount of rent due. It should also include a statement that both parties have agreed to the terms of the lease. There are two types of California Confirmation of Lease: a written and a verbal confirmation. A written confirmation must include all the terms of the lease and must be signed by both parties. A verbal confirmation is made when the landlord and tenant verbally agree to the terms of the lease. Both types of confirmation are legally binding and must be followed.
