If you are sharing accommodation with other tenants you may have an individual (each person signs a separate contract) or a joint (all tenants sign on the same document) contract.
If you have a joint contract you will be considered jointly and individually liable for rent and any damage to the property. Also, if one of tenant gives two months’ notice to leave, it ends the tenancy for ALL of you. For these reasons it’s important to be sure about who you want to live with and make sure all tenants know what they are signing up for.
