IANAL but I am a 2nd Assistant Director. Before a minor is hired by our company, their parents are required to submit their paperwork (that includes their Coogan account) to us. That is YOUR account designed to protect your earnings. A job can not legally hire you without that protection.
Also, that account can not even be withdrawn from until you are 18. https://www.actorsfcu.com/youth-accounts/coogan-accounts so your parents had to of gone about this in a criminal way to even be successful.
California state labor board, your SAG-Aftra Rep, and even the LA film office can all get you set up in fixing this whether it’s getting you a lawyer or stepping in on your behalf.
