Since the landlord accepted rent after the original lease expired, a tenancy­at­will was created. The tenant continues to occupy the unit under the same terms and conditions as in the expired lease. However, with a tenant­at­will, the landlord must give a sixty (60) day notice prior to any change in the tenancy, including increasing rent, an offer of a new lease, or termination of the rental arrangement. The landlord is not required to give this notice in writing unless the lease so provides. It is better practice however to provide written notice since the document offers some tangible evidence that notice was given. Likewise, the tenant must provide a thirty (30) day notice to the landlord if the tenant wants to terminate the tenancy. In this case, the landlord should have given the tenant sixty days to sign the new lease.
