A.R.S. § 23-327

If a minor is paid less than the minimum fair wage to which such minor is entitled under a mandatory minimum fair wage order, such minor may recover in a civil action an amount which is treble the full amount of the minimum wage, together with costs and a reasonable attorney's fee to be allowed by the court on the basis of time and effort expended by counsel in behalf of the plaintiff-employee if judgment is rendered against the employer, less any amount actually paid to the employee by the employer. Any agreement between the employee and the employer to work for less than the mandatory minimum fair wages is not a defense to the action.
