Under the Coogan Act (California Family Code Sections 6750–53 and California Labor Code Section 1700.37), 15% of her gross earnings are held in a trust account until she is an adult, paid into the account directly by her employer. The rest of the money can go to agents, managers, trainers, expenses, etc, at the direction of her parents.
The Coogan Act doesn't apply in Oregon. Oregon doesn't have an equivalent statute.
