Through a rental agreement, landlords and tenants mutually agree on fixed conditions such as rent, pet rules, duration of the contract, etc. Neither party may modify the agreement without the written consent of the other parties. A lease differs from a lease in that it is not a long-term contract and is usually done from month to month. This monthly lease expires and is renewed each month after the agreement of the parties concerned. As with a lease, the lessor can change the terms of the lease at the end of the term of the periodic lease. However, if a tenant does not intend to renew the lease, he must inform the lessor 21 days before the expiry of the lease, in accordance with the law. .
