No, you cannot execute a retro-dated agreement on the 2019 stamp. 1. The rent / rental contract must be paid and registered, before the start of the rent / leasing. The lease must be signed by all tenants and your landlord. If there are common tenants, each tenant should receive a copy of the agreement. If you are disabled, your landlord may need to change the lease if a contract term means you are worse off than someone without your disability. If you think that your lease could contain unfair terms, you can contact your nearest citizen councils. In England and Wales, most tenants do not have legal protection on a written lease. However, owners of social housing, such as municipalities and housing companies, usually get you a written lease.
