Cal. PEN § 536a

It is hereby made the duty of every commission merchant, broker, factor, or consignee, to whom any property is consigned or entrusted for sale, to make, when accounting therefor or subsequently, upon the written demand of his principal or consignor, a true written statement setting forth the name and address of the person or persons to whom a sale of the said property, or any portion thereof, was made, the quantity so sold to each purchaser, and the respective prices obtained therefor; provided, however, that unless separate written demand shall be made as to each consignment or shipment regarding which said statement is desired, prior to sale, it shall be sufficient to set forth in said statement only so many of said matters above enumerated as said commission merchant, broker, factor, or consignee may be able to obtain from the books of account kept by him; and that said statement shall not be required in case of cash sales where the amount of the transaction is less than fifty dollars. Any person violating the provisions of this section is guilty of a misdemeanor.
