Clarifies crime of interference with child custody; establishes graduated penalties for violations.

This bill clarifies and strengthens New Jersey's law against interfering with child custody. It defines specific actions as interference (like taking, detaining, or concealing a child to deprive a parent of custody) and creates a tiered penalty system: minor offenses (first/second) are disorderly persons offenses with a $500 minimum fine, while more severe violations (taking a child outside the state or for over 24 hours) are third-degree crimes, and taking a child outside the U.S. is a second-degree crime. The law also includes defenses for parents who reasonably believe they're protecting a child from immediate danger or fleeing physical harm, provided they notify authorities within 24 hours. It directly affects parents, guardians, or custodians involved in custody disputes who may take or hide a child.
