A tenancy agreement is a contract between you and your tenant, which may be written or verbal. It gives each party certain rights, such as the tenant’s right to occupy the property and the landlord’s right to receive rent. It also places obligations or responsibilities on the parties.
The terms of the agreement must conform with statutory legal obligations. If they do not then the terms would not be enforceable in a court. Even if renting to family or friends it is advisable to have a written agreement to avoid misunderstandings about the tenancy agreement.
