This is only possible with the permission of the landlord. The request must be made in writing and signed by both departing and remaining tenants. The landlord/manager also needs to receive the remaining tenant’s income details to assess whether they can pay the rent on their own. The landlord is legally entitled to refuse permission for letting the property solely to the remaining tenant or if applicable to a replacement tenant. It is possible that costs will be incurred, for instance for drawing up an addendum containing this amendment.
