The divorce ended. Life kept changing.

The two modes of post-divorce practice

Post-judgment family practice splits into two related but distinct disciplines:modification (changing the terms because something fundamental has changed) andenforcement (compelling compliance because the terms are being ignored). The motions, the standards, and the remedies are different. Many cases involve both: a modification motion to address a real change and an enforcement motion to recover what should have been paid while everything was happening.

At Simon Law Group, our family law attorneys handle post-divorce work throughout New Jersey. We represent both parties seeking modification and parties defending against unwarranted requests, and we pursue enforcement where the FJOD and PSA are being violated.

Modifying custody and parenting time

Under N.J. case law andN.J.S.A. 9:2-41, custody and parenting time orders can be modified when the moving party demonstrates a substantial change in circumstances affecting the child's best interests. The two-step test: first, the change; then, a fresh best-interests analysis under the statutory best-interests factors. Common triggers:

• A parent's relocation -- interstate moves typically require court approval; significant intrastate moves can also justify modification
• A significant change in a parent's work schedule that affects the parenting plan's workability
• Substance abuse, mental health crisis, or other fitness concerns
• Documented patterns of non-cooperation, parenting time obstruction, or parental alienation
• The child's evolving developmental, educational, or medical needs
• The child reaching an age where their stated preference deserves meaningful weight
• Domestic violence allegations or restraining order proceedings

Modifications can range from minor schedule adjustments to wholesale changes in the custody arrangement. Most cases that move forward are resolved through mediation or four-way negotiation; a smaller subset go to plenary hearing.

Modifying child support

Child support orders are modifiable underN.J. Court Rule 5:6A1and the Lepis v. Lepis2 changed-circumstances standard. Standard grounds:

• Significant increase or decrease in either parent's income, with documentation showing the change is meaningful rather than temporary
• Involuntary job loss with documented mitigation efforts (job search records, applications, interviews)
• A meaningful change in parenting time that affects the Guidelines worksheet
• Significant change in the child's medical, educational, or extracurricular needs
• Emancipation of one child reducing the per-child allocation
• Substantial changes in health insurance or child care costs
• Cost-of-living adjustments on long-running orders

Timing matters because support modification often turns on filing date and statutory limits on retroactive change. Contact counsel promptly when the change happens so the motion can be evaluated and filed without avoidable delay. Imputed income, where the court treats a voluntarily underemployed parent as earning what they could earn, is frequently litigated in modification cases.

Modifying alimony

Under N.J.S.A. 2A:34-231, alimony may be modified or terminated on changed circumstances. Standard grounds include:

• Substantial and permanent change in either party's financial circumstances
• Involuntary income reduction, with proof of the reduction, job-search or mitigation efforts, and whether the change is temporary or sustained
• Cohabitation by the recipient under N.J.S.A. 2A:34-23(n)2, analyzed through statutory factors such as intertwined finances, shared living arrangements, shared chores, recognition by family and friends, sharing of household responsibilities, joint social activity, and duration
• The paying spouse reaching full retirement age, creating a rebuttable presumption of good-faith basis for modification under N.J.S.A. 2A:34-23(j)3
• Significant increase in the recipient's income or assets
• Disability of either party

Termination and modification depend on the statute, the judgment, and the agreement language. Cohabitation cases are fact-intensive. Documentary discovery, witness testimony, and other admissible evidence may be needed when the issue is contested.

Enforcement when your ex won't comply

A Final Judgment of Divorce and the incorporated Property Settlement Agreement are enforceable as court orders. UnderN.J. Court Rule 1:10-31, a motion to enforce litigant's rights is the standard vehicle.

• Unpaid child support or alimony. Wage garnishment through the Probation Division (often already in place); bank account seizure; state and federal tax refund intercept; suspension of driver's, professional, and recreational licenses; contempt findings; and, in serious willful-nonpayment cases, coercive relief the court finds appropriate.
• Custody and parenting time violations. Make-up parenting time; modification of the arrangement; financial sanctions; therapeutic intervention (court-ordered therapy, including reunification-type treatment, is now subject to the scientific-validity, good-cause, and consent limits of N.J.S.A. 9:2-4 as amended by P.L. 2025, c.316, effective January 20, 2026); contempt findings; in extreme cases, change in custody.
• Failure to transfer property. Court orders compelling specific performance -- execution of deeds, transfer of titles, QDRO funding, account retitling. Attorney fees may be available where the rule and facts support fee shifting.
• Refinance and indemnification breaches. Where the PSA required refinancing of a mortgage or joint debt and the obligated spouse fails to do so, the court can compel sale, impose indemnification, or order the obligated spouse to pay damages from continued credit exposure.
• Insurance defaults. Failure to maintain life or health insurance securing support obligations can be cured by court order, with monetary damages and contempt remedies available.
• Non-disparagement and confidentiality breaches. Where the PSA includes protective provisions, enforcement runs through motion practice and contempt proceedings.

Emancipation and termination of support

Under N.J.S.A. 2A:17-56.671, there is a rebuttable presumption that a child is emancipated at age 19. But emancipation is not automatic -- the obligation continues until a court order terminates it. Support frequently extends past 19 when the child is enrolled full-time in an educational program or has another statutory basis for continuation or has disabilities preventing self-support. Conversely, a child may be emancipated earlier on marriage, military service, or financial independence. The right move is to file the motion at the right time, before avoidable arrears or overpayment disputes become the main issue.

College contribution post-judgment

Newburgh v. Arrigo1 college contribution is one of the most heavily litigated post-judgment issues in New Jersey family law. If the PSA addressed college directly -- caps, percentage allocations, type of school, custody of decisions -- the contractual terms generally control. If the PSA reserved or skipped the issue, either parent can file a motion when the child approaches enrollment, and the court runs the twelve-factor Newburgh analysis: each parent's ability to pay, the child's academic ability and motivation, available financial aid and loans, the parent-child relationship, the parents' background and expectations, the type of school, the reasonableness of cost. The better practice is to contact counsel before the enrollment and first-bill timeline creates unnecessary motion pressure.
