Child Support Modification - New Jersey
NEW JERSEY CHILD SUPPORT MODIFICATION FILING COMPANION
Use the Judiciary's current forms. This packet organizes facts, calculations, exhibits, and filing choices. It is not a substitute for the official FM post-judgment motion packet, the official FD application, a current financial statement, a Case Information Statement, a child-support worksheet, service, or a court order.
1. Select the Correct Docket Route
Route A — FM Dissolution Case
Use this route when the existing order is in a divorce, civil-union dissolution, or domestic-partnership termination case with an FM docket number.
☐ Current docket begins with FM.
☐ Use the Judiciary's current Family Multi-Purpose Post Judgment Motion Packet, CN 10483.
☐ Confirm the return date and current filing and delivery deadlines from the Judiciary before serving or filing.
☐ If the current Judiciary schedule applies, arrange receipt by the other party or counsel at least 24 calendar days before the return date, or mail at least 27 calendar days before that date.
Route B — FD Non-Dissolution Case
Use this route for a post-dispositional child-support application in a non-dissolution case with an FD docket number.
☐ Current docket begins with FD.
☐ Use the Judiciary's current Application for Modification of Court Order or Cross-Application for Modification of a Court Order, CN 11487.
☐ Provide the other party's current mailing address to the court.
☐ File the current and prior financial statements required by Rule 5:5-3(a).
☐ Do not replace the Family Part's current Rule 5:4-4 service process with an invented private service deadline.
Route C — Different Proceeding
☐ The matter involves UIFSA, another state's controlling order, public-assistance assignment, domestic violence, DCPP, an appeal, reconsideration, enforcement only, or another route requiring separate analysis.

| [________________] | [__/__/____] | [________________] | [________________] | [________________] |
3. Changed-Circumstances Record
Appendix IX-A, paragraph 23 requires a change in circumstances since entry of the existing order before the guidelines are used to modify support. A new guidelines edition, standing alone, is not an automatic basis for modification.
3.1 Identify Each Claimed Change
| Claimed change | Date it began | Facts at prior order | Current facts | Supporting exhibit |
|---|---|---|---|---|
| Income or earning capacity | [__/__/____] | [________________] | [________________] | [________________] |
| Parenting-time or residence schedule | [__/__/____] | [________________] | [________________] | [________________] |
| Child-care cost | [__/__/____] | [________________] | [________________] | [________________] |
| Health-insurance cost or availability | [__/__/____] | [________________] | [________________] | [________________] |
| Recurring unreimbursed health expense | [__/__/____] | [________________] | [________________] | [________________] |
| Other child need or household fact | [__/__/____] | [________________] | [________________] | [________________] |
3.2 Causation and Duration
☐ Explain whether the change is temporary, recurring, or expected to continue.
☐ Explain any voluntary employment change, disputed income, self-employment issue, disability, incarceration, severance, bonus, commission, benefit, or other income issue.
☐ Identify facts relevant to income imputation without declaring a result for the court.
☐ Do not treat the passage of three years as an automatic New Jersey modification ground. Appendix IX-A paragraph 14 concerns shared-parenting arrangements; paragraph 23 supplies the modification framework.

Family law covers the paperwork that shapes divorce, custody, child support, adoption, guardianship, and other family matters. These filings are emotional and high-stakes, and they also have to meet strict procedural rules for service, financial disclosure, and parenting plans. Clean, accurate paperwork keeps the focus on getting a workable outcome for the family instead of getting derailed by technical problems that delay hearings or force amended filings.
