California Code, Civil Code - CIV § 1812.306

(a) A purchaser's remedy for errors in or omissions from the membership camping contract of any of the disclosures or requirements of Sections 1812.302 to 1812.304, inclusive, shall be limited to a right of rescission and refund. Reasonable attorney's fees shall be awarded to the prevailing party in any action under this title. This limitation does not apply to errors or omissions from the contract, or disclosures or other requirements of this title, which are a part of a scheme to willfully misstate or omit the information required, or other requirements imposed by this title.

(b) Any failure, except a willful or material failure, to comply with any provision of Sections 1812.302 to 1812.304, inclusive, may be corrected within 30 days after receipt of written notice to the membership camping operator from the purchaser, and, if so corrected, there shall be no right of rescission. The membership camping operator or the holder shall not be subject to any penalty under this title. However, there can be no correction that increases any monthly payment, the number of payments, or the total amount due, unless concurred to, in writing, by the purchaser. “Holder” includes the seller who acquires the contract, or if the contract is purchased, a financing agency or other assignee who purchases the contract.
