New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 17-56.20

a. In enforcing all existing and future orders for support, and notwithstanding other provisions to the contrary, the State IV-D agency, without a new order, shall have the authority to assess interest or late payment fees on any support order not paid within 30 days of the due date.

b. The late payment fee or interest shall be determined by the State IV-D agency within amounts specified by the federal Department of Health and Human Services.

d. The collection of the fee or interest shall not directly or indirectly reduce the amount of current or overdue support paid to the obligee to whom it is owed.

e. The late payment fee or interest shall be uniformly applied in all cases administered under the State IV-D program, including public assistance, nonpublic assistance, and resource family cases.
