There is no increased legal flexibility by not signing an agreement, as the right to residential ownership cannot be cancelled and also covers oral agreements, so it is in your interest to read and understand the agreement. If you rent part of a house or unit to another tenant – and that tenant has a written lease with the owner of the premises – then they are your primary tenant. Each of the tenants may also terminate the rental agreement with or without the agreement of the other tenants if the fixed term of the rental agreement has expired by a valid notice. Check out our guide to find out what you can do at the end of your rental. As joint tenants are under contract, they all share the same responsibilities and have the same consequences as if they were tenants. . . .
