Subject to the provisions of the first paragraph of article L. 112-2 and articles L. 112-3, L. 112-3-1 and L. 112-4, automatic indexation of the prices of goods or services is prohibited.
Any clause in a successively executed contract, and in particular leases and rentals of any kind, providing for a period of variation in the index greater than the period elapsing between each revision is deemed to be unwritten.
Any clause in an agreement relating to residential premises that provides for indexation based on the “rents and charges” index used to determine general retail price indices is prohibited. The same applies to any clause providing for indexation based on the rate of legal increases set in application of law no. 48-1360 of 1st September 1948, unless the initial amount has itself been set in accordance with the provisions of the said law and the texts adopted for its application.
