A recipient of services may use his money as he chooses, unless he is a minor or prohibited from doing so under a court guardianship order. A recipient may deposit or cause to be deposited money in his name with a service provider or financial institution with the approval of the provider or financial institution. Money deposited with a service provider shall not be retained by the service provider. Any earnings attributable to a recipient's money shall accrue to him.
Except where a recipient has given informed consent, no service provider nor any of its employees shall be made representative payee for his social security, pension, annuity, trust fund, or any other form of direct payment or assistance.
When a recipient is discharged from a service provider, all of his money, including earnings, shall be returned to him.
