The amount of rent is freely fixed by the parties. Its payment terms (monthly, quarterly, at the beginning or end of term) are specified in the professional lease contract. The rent revision is not required by law but the contract may provide for a revision based on an index such as the index of rents for tertiary activities (ILAT) in an indexing clause. If nothing is specified in the lease, the same rent is applicable throughout the term of the lease. En savoir plus sur Entreprendre.Service-Public.fr
