New Jersey Statutes Title 44. Poor 44 § 1-141

If any of the relatives mentioned in section 44:1-140 of this Title shall fail to perform the order or directions of the director of welfare of a municipality with regard to the support of the poor person, or if the poor person is supported at public expense, the Superior Court in the county wherein the poor person has a legal settlement, or the municipal court of the municipality wherein the person has a legal settlement, upon the complaint of the director of welfare or two residents of the municipality or county may summon the persons chargeable before it as in other actions, summon witnesses, and adjudge that the able relatives pay such sum for each poor person as the circumstances may require in the discretion of the court, and as will maintain him or them and relieve the public of that burden. However, where it shall appear that the person or persons sought to be held were the child or children of the poor person and were abandoned and deserted by the poor person who failed to support and maintain them during minority, the aforementioned Superior Court or municipal court may revoke the order of the director of welfare or reduce the amount of said order against such child or children, in proportion to the actual support and maintenance rendered by said poor person to the child or children sought to be held. Any child now under an order to support a poor person may apply to the court which issued said order for the revocation or reduction of said order in accordance with the terms of this proviso. Violation of any such order shall constitute a contempt of court.

The county through its governing body may also bring appropriate action in any court of competent jurisdiction to recover any money due for the relief, support and maintenance of a poor person against a person chargeable by law therefor.
