Any deposit made in the name of a minor, or shares issued in a minor's name, shall be held for the exclusive right and benefit of the minor, free from the control or lien of all other persons except creditors, and together with the dividends or interest thereon shall be paid to the minor; and the minor's receipt, check, or acquittance in any form shall be a sufficient release and discharge of the depository for the deposits or shares, or any part thereof, until a conservator or guardian appointed for the minor shall have delivered a certificate of appointment to the depository. Deposits may be accepted pursuant to the authority set forth in chapter 527 , provided that either the custodian or the minor is a member of the credit union accepting the deposit.
