Veh. Code, § 3076

(a) All claims made by a franchisee for payment under the terms of a franchisor incentive program shall be either approved or disapproved within 30 days after receipt by the franchisor. When a claim is disapproved, the franchisee who submits it shall be notified in writing of its disapproval within the required period, and each notice shall state the specific grounds upon which the disapproval is based. A claim not specifically disapproved in writing within 30 days from receipt shall be deemed approved on the 30th day. Following the disapproval of a claim, a franchisee shall have one year from receipt of the notice of disapproval in which to appeal the disapproval to the franchisor and file a protest with the board. All claims made by franchisees under this section shall be paid within 30 days following approval. Failure to approve or pay within the above specified time limits, in individual instances for reasons beyond the reasonable control of the franchisor, do not constitute a violation of this article.

(b) Audits of franchisee incentive records may be conducted by the franchisor on a reasonable basis, and for a period of 18 months after a claim is paid or credit issued. Franchisee claims for incentive program compensation shall not be disapproved except for good cause, such as ineligibility under the terms of the incentive program, lack of material documentation, or fraud. Any chargeback to a franchisee for incentive program compensation shall be made within 90 days of the completion of the audit. If a false claim was submitted by a franchisee with the intent to defraud the franchisor, a longer period for audit and any resulting chargeback may be permitted if the franchisor obtains an order from the board.
