The termination of a lease, which occurs when a tenant gives up his interest to his landlord. Surrender can be express or implied. Express surrender is usually in the form of a deed. When the lease is for less than three years, no deed is needed provided that the tenant signs a written agreement to surrender. Implied surrender occurs when the actions of both parties show that they consider the lease to be at an end; for example, when the tenant gives up possession and the landlord reoccupies the property.
