In addition, the roommate agreement avoids future disputes and limits only you and your roommates. On the contrary, a rental document only limits your individual landlord and tenant and they have nothing to do with the colocation contract. Such things do not bother your landlord and he has no power to impose them; It is you who face it. It is therefore always preferable to make prior arrangements and agreements in order to avoid problems in the future. The purpose of the agreement defines the power, rights and duties between the roommates. You must clearly state the purpose of the agreement so that there are no conflicts in the future. Generally speaking, the purpose of the agreement is the same for colocation contracts that share the same rights and obligations, and there are few that have different reasons. . . .
