This case involves the father's attempt to relocate the children to another State over the mother's objection. He relocated anyway without obtaining an order permitting the move. This court held that N.J.S.A. 9:2-2 required him to obtain an order permitting the removal before the actual relocation. On the mother's later motion, the judge ordered the father to return the children. In upholding the judge's refusal to do a best interests analysis on the mother's motion, this court concluded that the time for the judge to determine whether plaintiff had established "cause" for the removal of the children would have been before the relocation occurred, and that the father had the ultimate burden of proof.
