Cal. Civ. Code § 1812.64
Every dance studio shall maintain a bond issued by a surety company admitted to do business in this state. The principal sum of the bond shall be 25 percent of the dance studio's gross income from the studio business in this state during the studio's last fiscal year, except that the principal sum of the bond shall not be less than twenty-five thousand dollars ($25,000) in the first or any subsequent year of operation.
A copy of the bond shall be filed with the Secretary of State, together with a declaration under penalty of perjury signed by the owner of the studio stating the dance studio's gross income from the dance studio business in this state during the last fiscal year. The information contained in the declaration shall not be subject to public inspection. If the person in whose name the bond is issued severs his or her relationship with the bonded dance studio, the new owner shall, as a condition of doing business, notify the Secretary of State of the change of ownership and of proof of compliance with Sections 1812.64 and 1812.65.
