A Marital Settlement Agreement (“MSA”) is one of the most important documents in a New Jersey divorce. It outlines the terms agreed upon by both spouses regarding issues such as child custody, parenting time, child support, alimony, and division of assets and debts. Once incorporated into a Final Judgment of Divorce, many people assume the agreement is set in stone forever. However, that is not always the case.
Under certain circumstances, New Jersey courts may allow portions of a Marital Settlement Agreement to be modified after a divorce is finalized.
A Marital Settlement Agreement is a legally binding contract between spouses that resolves the issues arising from their divorce. In New Jersey, courts favor settlement agreements because they allow couples to resolve disputes privately and efficiently rather than through lengthy litigation.
An MSA may address:
Once signed, the agreement becomes enforceable and may become part of the divorce judgment.

The answer depends on the type of provision involved and whether there has been a substantial and permanent change in circumstances.
Some terms are more flexible than others under New Jersey law.
Provisions That May Be Modified
Child Custody and Parenting Time
Courts in New Jersey always prioritize the best interests of the child. Even if parents agreed to a custody arrangement in their MSA, the court may modify it later if circumstances change.
Examples may include:
Child Support
Child support can often be modified if there has been a substantial change in financial circumstances.
Examples include:
New Jersey courts recognize that financial situations evolve over time, and support obligations may need to reflect those realities.
Alimony
Alimony may also be modified under certain circumstances unless the agreement specifically states otherwise.
Common reasons for modification include:
The party requesting the change must demonstrate a substantial and continuing change in circumstance as well as meet various statutory requirements.

Equitable Distribution
Property division terms are typically much harder to change after a divorce is finalized. Courts expect parties to fully disclose assets and negotiate equitable distribution carefully during the divorce process.
Absent extraordinary circumstances, equitable distribution provisions are considered final.
However, there are limited situations where a court may revisit these provisions, such as:
If one spouse hid assets or provided false financial information during the divorce, the court can reopen parts of the agreement.
A temporary inconvenience is usually not enough to justify modifying an MSA. Courts look for substantial, permanent, or long-term changes.
Examples may include:
The court will evaluate whether the change was foreseeable at the time the agreement was signed and whether modification is fair and necessary.
If you want to modify your Marital Settlement Agreement, you must look to your MSA. Does it require mediation before you can file a motion? Mediation is generally the first step. If not, you will need to file a motion with the court requesting relief.
The process may involve:
In some situations, former spouses can agree to modifications voluntarily without extensive litigation. However, it is important to properly memorialize any changes in writing and obtain a court order when appropriate.

Modifying a Marital Settlement Agreement can be legally and emotionally complex. Courts scrutinize requests for modification, especially when financial support or children are involved.
