Attribution is if a tenant finds someone to take over their lease. This is a good option if a tenant does not plan to return to the property. Rental agreements between tenants and landlords do not cover the rights and obligations of co-tenants. Colocation relationships are excluded from residential tenancy legislation in all provinces and territories and disputes cannot be resolved by the Landlord Tenant Board. If you`re creating a roommate agreement, you`re less likely to argue with your roommates all the way down, as everything should be written into the agreement that all roommates sign. Colocation agreements can help clarify things from the beginning. If a tenant finds someone who wants to take over the lease, the tenant must obtain written permission from the landlord to assign the lease. .
