A savings institution may issue accounts in the name of any administrator, executor, custodian, conservator, guardian, trustee, or other fiduciary for a named beneficiary or beneficiaries. The payment of funds from any such account pursuant to a check or other written order of withdrawal signed by the fiduciary, the delivery of funds in such account to such fiduciary, or a receipt signed by any such fiduciary with regard to the payment of funds from such account, shall be a valid and sufficient release and discharge of the institution for the payment or delivery so made.
