Ark. Code Ann. § 9-26-302

A bank, broker, issuer, third-party, or transfer agent incurs no liability by reason of his or her treating a minor as having capacity to transfer a security, to receive or to empower others to receive dividends, interest, principal, or other payments or distributions, to vote or give consent in person or by proxy, or to make elections or exercise rights relating to the security, unless prior to acting in the transaction the bank, broker, issuer, third-party, or transfer agent had received written notice in the office acting in the transaction that the specific security is held by a minor or unless an individual conducting the transaction for the bank, broker, issuer, third-party, or transfer agent had actual knowledge of the minority of the holder of the security. Except as otherwise provided in this subchapter, such a bank, broker, issuer, third-party, or transfer agent may assume without inquiry that the holder of a security is not a minor.
