Ariz. Rev. Stat. § 32-2197.09
A person shall not sell or lease or offer for sale or lease in this state timeshare interests in a timeshare plan without first obtaining a public report or authorization to conduct pre-sales from the commissioner. Unless exempt, any sale or lease of timeshare interests in a timeshare plan that consists of twelve or more timeshare interests before issuance of the public report or authorization to conduct pre-sales or failure to deliver the public report or evidence of pre-sale authorization renders the sale or lease rescindable by the purchaser or lessee. An action by the purchaser or lessee to rescind the transaction must be brought within three years of the date of the execution of the purchase or lease agreement by the purchaser. In any rescission action, the prevailing party is entitled to reasonable attorney fees as determined by the court.
