N.J. Stat. Ann. § 34:15-48

The commissioner and each deputy commissioner of compensation is hereby authorized and empowered when in his judgment it shall be advisable, to appoint a representative with power to act for a person who may be entitled to compensation, by legally receiving and disbursing said compensation under the direction of the commissioner or any deputy commissioner of compensation, when it shall appear that such person is mentally, legally or physically unable to properly receive or disburse said compensation, or when said person, after due diligence, cannot be located. Whenever the person entitled to compensation is a minor child, and the commissioner or any deputy commissioner of compensation shall determine that there is no proper person available to receive and disburse said compensation for such child, then the State Board of Children's Guardians, as constituted by the provisions of chapter five, of Title Institutions and Agencies (s. 30:5-1 et seq.), may be appointed as the representative of such minor child.
