If the payee for any payment under this chapter is a minor, or if the Retirement Commission finds that any payee is legally incapable of giving a valid receipt and discharge for any payment due him, the Comptroller may, upon the advice of the Retirement Commission, make the payment, or any part thereof, to the person or persons whom the Retirement Commission finds to be caring for and supporting the payee, unless the Retirement Commission has received due notice of claim from a duly appointed guardian or committee of the payee. A payment so made shall be a complete discharge of the obligations of the state to the extent of and as to that payment, and the state shall have no obligations regarding the application of the payment.
