Minn. Stat. § 51A.251

An association may issue deposit accounts or negotiable order of withdrawal accounts to any married person or minor as the sole and absolute owner of the account, and receive payments thereon by or for the other, and pay withdrawals or drafts, accept pledges to the association, and act in any other manner with respect to the accounts on the order of the married person or minor. Any payment or delivery of rights to a married person or to any minor, or a receipt of or acquisition signed by a married person or by a minor who holds an account, shall be a valid and sufficient release and discharge of the association for any payment so made or delivery of rights to the married person or minor. In the case of a minor, the receipt, acquittance, pledge or other action required by the association to be taken by the minor shall be binding upon the minor as if the minor were of full age and legal capacity. The parent or guardian of the minor shall not in the capacity as parent or guardian have the power to attach or in any manner to transfer any account issued to or in the name of the minor; provided, however, that in the event of the death of the minor the receipt or acquittance of either parent or of a person standing in loco parentis to the minor shall be a valid and sufficient discharge of the association for any sum or sums not exceeding in the aggregate $2,500 unless the minor shall have given written notice to the association to accept the signature of the parent or person.
