If the contractor fails to provide the purchaser, within the time limit set by the purchaser, with information on the technical and accounting elements of the cost price of the services which are the subject of the contract, or provides inaccurate information, the purchaser may, after formal notice has remained without effect, decide to suspend the payments to be made up to a limit of one tenth of the amount of the contract when the default is due to the contractor, or withhold an equivalent amount. After a further unsuccessful formal notice, the purchaser may decide to transform this deduction into a definitive deduction, without prejudice to the possible termination of the contract to the detriment of the contractor.
When a cost estimate is made before the contract is notified, the purchaser shall indicate in the consultation documents and in the contract the penalties applicable in the event of failure to comply with the obligation set out in the first paragraph of article L. 2196-5.
