Cal. HNC § 715

Within one month after the closing of a transaction in which title to a yacht is conveyed from a seller to a purchaser through a licensed broker, the licensee shall provide, or cause to be provided to the seller and purchaser, a closing statement in writing of the selling price thereof, including all charges and credits which shall be itemized, and in the event an exchange of yachts is involved, the information shall include a description of the yachts and amount of added money consideration, if any. The licensee shall affix his or her signature to the closing statement to attest to the facts provided in the closing statement. If the transaction is closed through escrow and the escrowholder renders a closing statement which reveals the information, that shall be deemed compliance with this section on the part of the licensed broker.
