This is an issue of state law, and I do not practice in Arizona, but in New Jersey, this kind of thing is mandatory. The Court holds a hearing to make sure that the settlement was a fair one, and then the money is deposited in a fund held by the Surrogate, who holds the money until the minor reaches eighteen. It is done to protect against the possibility that the money will be spent on things other than what is in the interests of the child. Parents can make an application to withdraw the money and they can get permission for this if they can demonstrate that the money is being spent on something that the child needs.
