Within one month after the close of escrow for the transfer of title to real property or the sale of a business opportunity through a real estate broker, the broker must inform the buyer and seller in writing of the sales price. In the case of an exchange of real property or a business opportunity, the information must include a description of the property and the amount of added money consideration, if any. Should the transaction be closed through neutral escrow, a closing statement from the escrow holder will constitute compliance on the part of the broker.
