N.J. Stat. § 5:9-20
If the person entitled to a prize or any winning ticket is under the age of 18 years, and such prize is less than $5,000.00, the director may direct payment of the prize by delivery to an adult member of the minor's family or a guardian of the minor of a check or draft payable to the order of such minor. If the person entitled to a prize or any winning ticket is under the age of 18 years, and such prize is $5,000.00 or more, the director may direct payment to such minor by depositing the amount of the prize in any bank to the credit of an adult member of the minor's family or a guardian of the minor as custodian for such minor. The person so named as custodian shall have the same duties and powers as a person designated as a custodian in a manner prescribed by the "New Jersey Uniform Gifts to Minors Act," P.L. 1963, chapter 177 (C. 46:38-13 et seq.) and for the purposes of this section the terms "adult member of a minor's family," "guardian of a minor" and "bank" shall have the same meaning as in said act. The director shall be discharged of all further liability upon payment of a prize to a minor pursuant to this section.
