California Code, Civil Code - CIV § 2983

(a) Except as provided in subdivision (b), if the seller, except as the result of an accidental or bona fide error in computation, violates any provision of Section 2981.9, or of subdivision (a), (j), or (k) of Section 2982, the conditional sale contract shall not be enforceable, except by a bona fide purchaser, assignee, or pledgee for value, or until after the violation is corrected as provided in Section 2984, and, if the violation is not corrected, the buyer may recover from the seller the total amount paid, pursuant to the terms of the contract, by the buyer to the seller or his or her assignee. The amount recoverable for property traded in as all or part of the downpayment shall be equal to the agreed cash value of the property as the value appears on the conditional sale contract or the fair market value of the property as of the time the contract is made, whichever is greater.

(b) A conditional sale contract executed or entered into on or after January 1, 2012, shall not be made unenforceable solely because of a violation by the seller of paragraph (2) or (5) of subdivision (a) of Section 2982. In addition to any other remedies that may be available, the buyer is entitled to any actual damages sustained as a result of a violation of those provisions. Nothing in this subdivision affects any legal rights, claims, or remedies otherwise available under law.
