(a) No verbal agreement or written agreement other than a contract on the commission's official form shall be accepted by the commission.

(b) No contract between a promoter and manager or boxer shall be enforced by the commission until all contracts between the promoter and the contestants for a particular match are filed with the commission and meet the requirements of these rules and the provisions of the code applicable to professional boxing. All contracts for an event shall be filed with the commission no later than the time periods specified in Rule 240.

(c) Contracts are prohibited wherein a certain sum other than federal, state or local government taxes is taken by the club from the gate receipts or, where applicable, receipts from the sale, lease, transfer, or other exploitation of broadcasting and television rights, before a boxer is paid a percentage of the balance of said receipts for his or her services.
