A savings bank and any federal savings bank may issue savings accounts to any minor or other person under disability as the sole and absolute owner of such savings account. Such savings bank may receive payments by or for such owner, pay withdrawals, accept pledges to the savings bank, and act in any other manner with respect to such account on the written instruction of such savings account holder in accord with this chapter. Any payment or delivery of rights to any minor or other person under a disability, or a receipt or acquittance signed by a minor or other person under a disability, who holds a savings account, shall be a valid and sufficient release of such savings bank for any payment so made or delivery of rights to such minor or person. The receipt, acquittance, pledge or other action required by the savings bank to be taken by such minor or person shall be binding upon such minor or person as if he were of full age and legal capacity. The parent or guardian of such minor or person shall not in his capacity as parent or guardian have the power to attach or to transfer any savings account issued to, or in the name of, such minor or person; provided, however, that in the event of the death of such minor or person, the receipt or acquittance of either parent, a person standing in loco parentis, guardian or conservator of such minor or person shall be a valid and sufficient discharge of such savings bank for any sum not exceeding One Thousand Dollars ($1,000.00), unless the minor or person has given written notice to the savings bank not to accept the signature of such person.
