The contractor shall certify in writing to the property owner that the funds paid by the property owner to the contractor in consideration of the lien waivers will be used by the contractor to pay for the labor, materials and services for which the lien waivers were provided in full.

The amount due or to become due under the original contract for the payment for the labor, materials and services from the property owner to the contractor shall not be reduced if the property owner fails to request and obtain said lien waivers prior to the disbursement of funds to the contractor.
