In AZ, the child support is owed to the custodial parent, not the child(ren). If someone else is now your caretaker, that person can get child support from your parents for your and your sister's support. Your legal guardian can seek services from Division of Child Support Services.
This is not the courthouse. This is Google guides..... no one on here is qualified or capable of giving you the legal answer that you seek contact your attorney
