Circumstances change after a divorce is finalized. A layoff, a move, a remarriage, or a shift in your child’s medical needs can leave a past order no longer fitting your life. Under New York law, you can modify custody, child support, and spousal maintenance orders once you show a substantial change in circumstances. You file this request in the Supreme Court, New York County where your judgment was entered, or in the New York County Family Court.

Our office represents parents and former spouses seeking a change, as well as those defending an order that already works for them.

Once your divorce judgment has been entered, a post-divorce modification is the court proceeding that changes the terms of your existing custody, visitation, child support, or spousal maintenance order, and the Domestic Relations Law together with the Family Court Act authorize these applications.
A modification differs from an enforcement or violation petition. An enforcement petition asks the court to make the other party comply with the written order. This request can include a money judgment, wage garnishment, or a contempt finding. Both are often filed together in Manhattan when one parent is behind on support and asks for a reduction.
Jurisdiction depends on the relief you want. The New York County Supreme Court retains authority over the divorce judgment it entered, while New York County Family Court holds concurrent authority over custody, visitation, and child support after judgment. The Family Court’s power to change a maintenance award set in a Supreme Court judgment is limited, so maintenance applications return to the Supreme Court.
| Order Type | Standard to Modify | Where to File the Request |
|---|---|---|
| Custody and parenting time | Substantial change in circumstances plus the child's well-being | Supreme Court or Family Court, New York County |
| Child support (court-ordered) | Substantial change, 3 years elapsed, or 15% income change | Family Court or Supreme Court, New York County |
| Child support set by agreement | Same triggers, unless the parties validly opted out in writing | Family Court or Supreme Court, New York County |
| Spousal maintenance | Substantial change in circumstances | Supreme Court, New York County |
| Maintenance set by a settlement agreement | Extreme hardship, unless the agreement permits modification | Supreme Court, New York County |
| Property division | Not modifiable absent fraud, duress, or a similar defect | Supreme Court, New York County |
Meeting one of the child support grounds may entitle you to a hearing, though the court still decides whether modification is warranted based on your current circumstances.
You can request a custody or visitation modification in Manhattan when a substantial change in circumstances has occurred since entry of the last order and the proposed adjustment serves your child’s best interests. Proving a change in circumstances alone is insufficient if the court determines the modification does not benefit your child.
Once a substantial change is established, the court reassesses the child’s best interests using the factors set out in Domestic Relations Law Section 240 and New York case law. Judges weigh:
For older children, the court also weighs the child’s own preference. In contested cases, Manhattan judges frequently appoint an attorney for the child and may order a forensic evaluation before issuing a ruling.
Richard Roman Shum can review your current custody order and tell you if the evidence supports a petition.
We Are Here to Help You
Fighting against the legal system can be terrifying, but with Richard Shum, you never have to fight alone.
Child support can be modified in New York on three separate grounds. These include a substantial change in circumstances, the passage of three years since the order was entered, last modified, or adjusted, or a change of 15 percent or more in either parent’s gross income. Proving any single ground allows you to request a formal review. These provisions appear in Family Court Act Section 451 and apply to orders entered after October 13, 2010, unless both parties validly opted out in a written agreement.
Seeking a downward modification after a loss of income requires proof that the earnings reduction was involuntary and that you actively searched for comparable employment. In Manhattan, a parent who resigns, voluntarily accepts lower pay, or gets terminated for misconduct will still face support obligations based on imputed earning capacity.
Upward modifications follow similar principles, as a 15 percent increase in the paying parent’s income, new medical or educational costs, or rising childcare expenses can justify higher payments. Unpaid child support arrears accrued before filing your petition cannot be reduced or cancelled, making your filing date just as critical as your underlying financial evidence.
Key Takeaway: New York allows a child support modification review every three years, or immediately if either parent’s income changes by 15 percent or more.
You can modify post-divorce spousal maintenance by proving a substantial change in circumstances, though the governing standard depends on whether the original award stemmed from a judicial ruling or a settlement agreement.
Under Domestic Relations Law Section 236, post-divorce maintenance is awarded as either durational (lasting for a fixed term) or non-durational (continuing indefinitely). In Manhattan, courts predominantly grant durational awards aligned with statutory guidelines. A modification request for a durational award seeks to adjust payment amounts within that designated timeframe, whereas non-durational awards remain subject to adjustment as long as payments continue.
For both durational and non-durational maintenance, the burden required to modify payments depends on how the award was created. A court-ordered award requires proving a substantial change in circumstances, whereas maintenance established by a stipulation of settlement requires showing extreme hardship unless the agreement specifies otherwise. Reviewing your settlement terms is a critical first step prior to filing a petition in court, as non-durational awards carry ongoing financial exposure while durational awards operate under strict timeframes.
Spousal maintenance automatically terminates when the recipient remarries. Under Domestic Relations Law Section 248, the court can also modify or terminate maintenance if you prove the recipient habitually lives with another person and holds themselves out as that person’s spouse. Cohabitation alone is often not enough. Manhattan judges look for shared finances, joint leases or accounts, and public representations of the relationship, and many settlement agreements define cohabitation more broadly than the statute does.
Richard Roman Shum can review your judgment or settlement agreement to clarify the exact legal standard controlling your maintenance obligation.

A valid prenuptial or postnuptial agreement can limit or waive the right to seek certain modifications, and New York courts routinely enforce those provisions. Spouses can agree to a fixed maintenance amount and term, waive the right to seek an increase, or agree that maintenance is non-modifiable regardless of later financial changes.
These contractual waivers have specific legal limits. Courts can set aside maintenance waivers that leave a former spouse dependent on public assistance, and agreements remain vulnerable to challenges involving fraud, duress, unconscionability, or execution defects. Enforcing a properly executed marital contract carries strong weight under New York law.
Child-related provisions are treated differently under the law, as parents cannot contract away a child’s right to financial support or bind the court on custody decisions. A Manhattan judge will review child support terms for compliance with the Child Support Standards Act and statutory opt-out requirements, determining custody based on the child’s best interests at the time of the application.
Key Takeaway: New York courts enforce valid prenuptial and postnuptial maintenance waivers, but child support and custody terms always remain subject to judicial review.
The controlling test across custody, support, and maintenance modifications is a substantial change in circumstances since the last order. This change must be significant, must have occurred after entry of the existing order, and must not have been anticipated when the original order was drafted.
Qualifying facts depend on the specific relief you seek. Support modifications focus on income changes, employment shifts, medical issues, and child-related expenses, whereas custody modifications center on home environments, developmental needs, and parental conduct. Disagreement over schedules, minor income fluctuations, or dissatisfaction with a prior agreement rarely satisfy this legal burden.
Manhattan judges require clear documentary evidence to prove changed circumstances. In E.S. v H.G., 2025 NY Slip Op 50610(U), the court highlighted how post-judgment disputes demand objective proof rather than unsupported assertions. Submitting affidavits without supporting tax returns, pay stubs, medical records, or school documentation frequently results in summary dismissal without a hearing.
A custodial parent’s move can support a custody modification request, and the analysis depends on distance, motive, and effect on the child rather than on any fixed mileage rule. Most Manhattan parenting agreements require advance written notice of a move and set geographical boundaries beyond which court approval or parental consent is mandatory.
New York courts apply the factors established in Tropea v. Tropea, 87 N.Y.2d 727 (1996), analyzing:
A move from Manhattan to Westchester or New Jersey is evaluated under this same framework, even if the geographic distance is relatively small.
Relocation cases often involve cross-petitions where one parent seeks relocation approval while the other requests primary physical custody. In John N. v Melissa A., 2024 NY Slip Op 50923(U), both parents filed competing motions over a mother’s proposed relocation with the child. Moving without prior approval or consent severely weakens a parent’s legal standing in court.

A modification begins with a petition in Family Court or a post-judgment motion, often by order to show cause, in the Supreme Court matrimonial part that handled your divorce. Once served, the responding party submits opposing papers, and the court determines whether the filings justify an evidentiary hearing.
You must file in the Supreme Court when requesting maintenance adjustments, resolving contractual interpretation issues from your divorce judgment, or addressing intertwined financial and custody matters.
New York County Family Court handles child support and custody applications, where you can use the NY Courts DIY system to generate support modification petitions. If you already have an active Family Court proceeding, you must submit new modification requests to that venue.
Separation agreement terms and court jurisdiction rules can dictate where you submit your petition, though specific judgment language may direct your case to a single forum. An attorney can help you determine the correct court to prevent procedural delays.
Gather these records prior to filing your modification request:
A completed Statement of Net Worth is mandatory in proceedings involving financial relief, and failing to provide full disclosure harms your credibility before a Manhattan judge.
Key Takeaway: Choosing between Supreme Court and Family Court depends on where your original judgment was entered and the specific type of relief you request.

Matrimonial records in New York are confidential and protected from general public inspection, extending to post-judgment modification filings. Under the Domestic Relations Law, matrimonial files can only be accessed by the parties, their designated attorneys, or individuals holding a specific court order, protecting financial affidavits and settlement agreements filed in Manhattan Supreme Court.
You can request additional privacy protections when filing your papers. Parties can move to seal sensitive exhibits, file financial statements under confidentiality agreements, or redact financial account numbers, home addresses, and personal health information. Courts can also restrict access to children’s medical or school records and withhold physical addresses in cases involving safety concerns.
Family Court proceedings involving minor children operate under strict privacy guidelines, and judges can close courtrooms during sensitive testimony. Because privacy protections are not entirely automatic, you should submit requests for redaction or sealing when initially filing your court documents.
Petitions relying on assumptions rather than concrete documentation face dismissal. Claiming a former spouse’s income has increased without providing pay records, subpoenaed financial data, or formal disclosure requests leaves the court without a factual basis to grant relief. Similarly, allegations regarding substance abuse or unmet child needs require medical records, reports, or independent witness testimony.
Your existing court order remains legally binding until a judge signs a modified order. Unilaterally reducing child support payments generates non-dischargeable arrears, while withholding parenting time can lead to violation petitions, compensatory time awards, attorney fees, or contempt findings. Disregarding court orders damages your credibility and undermines your modification request.
Modification petitions must be served on the opposing party in strict compliance with court directives and deadlines set in an order to show cause. Defective service causes procedural delays or petition dismissals, resetting your timeline and delaying financial or custodial relief. Additionally, failing to provide contractually required written notice before relocating can be treated as a material breach of your agreement.

An uncontested modification in Manhattan can be finalized in approximately two to four months, whereas a contested custody or support proceeding often takes a year or longer. Case duration depends on party cooperation, required financial discovery, and whether the court orders forensic evaluations.
Financial support modifications are retroactive to your initial filing date, which helps mitigate the impact of court delays. Custody modifications are not retroactive, meaning parents facing urgent safety concerns should request temporary emergency relief when initiating the proceeding.
When a former spouse fails to obey a court order, you should file an enforcement or violation petition rather than a modification request. Enforcement proceedings ask the court to compel compliance and penalize non-compliance, and you can file these applications in New York County Family Court or as post-judgment motions in Manhattan Supreme Court.
For unpaid support obligations, courts can issue money judgments, execute income withholdings, seize bank accounts or tax refunds, suspend driver’s or professional licenses, and order payment of attorney fees. Willful failure to pay support can result in a finding of contempt and up to six months of incarceration. The Support Collection Unit can also enforce support orders administratively without court appearances.
Custody and visitation violations are addressed through violation petitions where Manhattan judges can order make-up parenting time, mandate parental counseling, award legal fees, or modify custody schedules. In severe cases, persistent interference with parental rights constitutes a change in circumstances that justifies transferring custody.

“Most kind and professional lawyer. A true gift. He saved me from the brutal claw of my management company and saved me a lot of money and pain.”
Yes, you can modify custody, visitation, child support, and spousal maintenance at any time provided you prove a substantial change in circumstances since the prior order. Property division awards are final and cannot be modified unless you establish legal grounds such as fraud, coercion, or mutual mistake.
You can represent yourself in court and use the free NY Courts DIY program to generate Family Court support petitions. However, modification proceedings require strict compliance with evidence rules, financial disclosure mandates, and statutory standards. An improperly prepared petition can result in a dismissal, which may prevent you from seeking legal relief until new circumstances arise. Working with an attorney helps you present a strong case and avoid procedural mistakes.
If you file in Manhattan Supreme Court, your post-judgment application returns to the matrimonial part that issued your divorce judgment. If that judge is no longer on the bench or has been reassigned, the case is assigned to the part managing that judicial inventory. Family Court petitions are assigned to a Family Court judge or support magistrate.
No, courts require proof that an income drop was involuntary and that the parent diligently pursued comparable employment. If a judge finds an income reduction was voluntary, support will be calculated based on the parent’s prior earning capacity rather than reduced current earnings.
You can file an enforcement or violation petition in court. For unpaid financial obligations, judges can enter money judgments, garnish wages, suspend driver’s licenses, or impose sanctions and jail time. For parenting schedule violations, courts can order make-up parenting time, award attorney fees, or hold the non-compliant parent in contempt.
A child’s preference is one factor a Manhattan judge evaluates, carrying greater weight as the child matures. A child’s preference alone does not control the outcome, and the court investigates whether the desire reflects independent wishes or parental influence. An attorney appointed for the child communicates that preference to the court.
