N.J. Stat. § 9:2-4
The Legislature finds and declares that it is in the public policy of this State to assure minor children of frequent and continuing contact with both parents after the parents have separated or dissolved their marriage and that it is in the public interest to encourage parents to share the rights and responsibilities of child rearing in order to effect this policy.
In any proceeding involving the custody of a minor child, the rights of both parents shall be equal and the court shall enter an order which may include:
In making an award of custody, the court shall consider but not be limited to the following factors: the parents' ability to agree, communicate and cooperate in matters relating to the child; the parents' willingness to accept custody and any history of unwillingness to allow parenting time not based on substantiated abuse; the interaction and relationship of the child with its parents and siblings; the history of domestic violence, if any; the safety of the child and the safety of either parent from physical abuse by the other parent; the preference of the child when of sufficient age and capacity to reason so as to form an intelligent decision; the needs of the child; the stability of the home environment offered; the quality and continuity of the child's education; the fitness of the parents; the geographical proximity of the parents' homes; the extent and quality of the time spent with the child prior to or subsequent to the separation; the parents' employment responsibilities; and the age and number of the children. A parent shall not be deemed unfit unless the parents' conduct has a substantial adverse effect on the child.
The court, for good cause and upon its own motion, may appoint a guardian ad litem or an attorney or both to represent the minor child's interests. The court shall have the authority to award a counsel fee to the guardian ad litem and the attorney and to assess that cost between the parties to the litigation.
