Bus. & Prof. Code, § 22502.1

It shall be unlawful for a ticket seller to contract for the sale of tickets or accept consideration for payment in full or for a deposit for the sale of tickets unless the ticket seller meets one or more of the following requirements:

(a) The ticket seller has the ticket in his or her possession.

(b) The ticket seller has a written contract to obtain the offered ticket at a certain price from a person in possession of the ticket or from a person who has a contractual right to obtain the ticket from the primary contractor.

(c) The ticket seller informs the purchaser orally at the time of the contract or receipt of consideration, whichever is earlier, and in writing within two business days, that the seller does not have possession of the tickets, has no contract to obtain the offered ticket at a certain price from a person in possession of the ticket or from a person who has a contractual right to obtain the ticket from the primary contractor, and may not be able to supply the ticket at the contracted price or range of prices.

Nothing in this section shall prohibit a ticket seller from accepting a deposit from a prospective purchaser as part of an agreement that the ticket seller will make best efforts to obtain a ticket at a specified price or price range and within a specified time, provided that the ticket seller informs the purchaser orally at the time of the contract or receipt of consideration, whichever is earlier, and in writing within two days, of the terms of the deposit agreement, and includes in the oral and written notice the disclosures otherwise required by this section.
