Unlike most states, New Jersey delivers child support enforcement through Probation Services within the state court system rather than a typical executive-branch human services office, even though the Division of Family Development is the state's overall federal IV-D administrator.
Cases are handled at the county vicinage level through the courts, which locate noncustodial parents, establish paternity, set support orders, and collect and enforce payments once a case is active.

How to Apply for Child Support in New Jersey
A parent or caretaker of a child can apply for New Jersey child support services through the njchildsupport.gov portal or by contacting the Probation Child Support Enforcement office in their county's Superior Court vicinage. Families already receiving WFNJ (New Jersey's TANF program) or Medicaid are typically referred for services automatically.
The application requires identifying information for both parents and the child, along with any existing custody or support paperwork. The county vicinage then works to establish paternity if needed and get a support order in place.
How to Collect Child Support Payments in New Jersey
New Jersey collects most support through income withholding once an order is active, disbursed to the receiving parent by a Way2Go debit card or through the New Jersey Family Support Payment Center.
Case status and payment information can be checked through the caseinfo.njchildsupport.gov portal, available statewide regardless of which county vicinage is managing the case.
Missed Payments & Enforcement
Because enforcement runs through the courts, New Jersey can use both administrative tools — tax refund interception, license suspension, credit bureau reporting — and direct judicial enforcement like contempt proceedings.
As in every state, federal law allows a passport to be denied or revoked once past-due support exceeds $2,500.
