Cal. Lab. Code § 1700.23
Every talent agency shall submit to the Labor Commissioner a form or forms of contract to be utilized by such talent agency in entering into written contracts with artists for the employment of the services of such talent agency by such artists, and secure the approval of the Labor Commissioner thereof. Such approval shall not be withheld as to any proposed form of contract unless such proposed form of contract is unfair, unjust and oppressive to the artist. Each such form of contract, except under the conditions specified in Section 1700.45, shall contain an agreement by the talent agency to refer any controversy between the artist and the talent agency relating to the terms of the contract to the Labor Commissioner for adjustment. There shall be printed on the face of the contract in prominent type the following: "This talent agency is licensed by the Labor Commissioner of the State of California."
