A motion to set aside a divorce decree asks the court that entered your final judgment to vacate it and reopen the case. Courts grant these motions sparingly because final judgments are meant to stay final, so you need a specific legal ground recognized under Federal Rule of Civil Procedure 60(b) or its state equivalent, you need to file within a strict deadline, and you need to show that reopening the case would actually produce a different outcome.
Grounds a Court Will Accept
Regret, hindsight, or a general sense that the settlement was unfair will not get a decree reopened. The court needs one of a handful of recognized reasons.
Fraud or Hidden Assets
This is the most common ground. One spouse concealed bank accounts, retirement funds, business interests, or other property during the divorce, and the other spouse discovered it only after the decree was signed. If the concealment produced a property division that would not have happened with honest disclosure, the court can vacate the judgment.
You need concrete proof, not suspicion. Undisclosed bank statements, property records, tax returns showing unreported income, or communications where your ex discusses hiding money are the kind of evidence that moves a judge. You also have to show you could not have uncovered the fraud during the original case with reasonable effort. If the records were publicly available and you simply did not look, most judges will not be sympathetic.
Mistake or Excusable Neglect
Rule 60(b)(1) covers mistake, inadvertence, surprise, or excusable neglect that affected the outcome. In a divorce context, that might be a significant error in valuing a major asset, a misunderstanding about which debts were marital, or a failure to respond to the petition because of serious illness or military deployment.
The word “excusable” does real work. Courts ask whether a reasonably careful person in your situation would have made the same mistake. Forgetting a hearing or deciding not to participate does not qualify. If the neglect was willful, the court will weigh whether reopening the case would unfairly prejudice your ex and whether you have a legitimate claim worth hearing.
Duress, Coercion, or Incapacity
A settlement signed under threats, financial control that left you with no real choice, or other intimidation may not be enforceable. The pressure has to be severe enough to overcome a reasonable person’s free will. Feeling pressured by the stress of divorce is not enough. Mental incapacity at signing, whether from medication, illness, or a psychological condition, can support a set-aside on similar reasoning.
Newly Discovered Evidence
Rule 60(b)(2) allows relief for evidence that existed during the original case but could not have been found through reasonable effort, and that is significant enough to likely change the result. A minor detail that would not have shifted property division or support will not justify reopening the case.
Default Judgments and Defective Service
Set-aside motions are common where one spouse never participated. That happens when you were never properly served, when you were served but did not understand the consequences of ignoring the papers, or when hospitalization, incarceration, or similar circumstances kept you from responding. Judges are generally more willing to set aside default judgments than contested ones, especially when the absent spouse had a real reason for not appearing and has a genuine defense to raise.
Extraordinary Circumstances
Rule 60(b)(6) permits relief for “any other reason that justifies relief.” It is not an open door. Courts reserve it for truly extraordinary situations that fall outside the other five categories, and it cannot be used to sidestep a deadline you missed on another ground. Successful motions under this provision are rare.
How Long You Have to File
Deadlines are strict, and missing one defeats the motion no matter how strong the underlying case.
Motions based on mistake, excusable neglect, newly discovered evidence, or fraud must be filed within a “reasonable time” and no later than one year after the judgment was entered. The one-year clock runs from the date the decree was signed, not from the date you discovered the problem. This catches people in fraud cases where hidden assets may not surface for years.
Motions under the catch-all for extraordinary circumstances have no fixed outer deadline but still must be filed within a reasonable time. Waiting months after learning about the issue, without a good explanation, will likely sink the motion.
Clerical mistakes, such as a typo or a math error in the judgment, are handled separately under Rule 60(a) and can be corrected whenever they are found. That provision does not reach substantive disagreements about the terms.
State rules often track these federal timelines, but some set shorter or longer deadlines. Check your local court rules or ask an attorney to confirm what applies in your case.
Showing the Outcome Would Have Been Different
Grounds and timing are not enough. Most courts also require what lawyers call a meritorious defense or meritorious claim: a showing that reopening the case would actually lead to a different result. A judge will not vacate a decree and relitigate a divorce only to arrive at essentially the same place.
Your motion should explain not just what went wrong, but what the corrected outcome should look like. If your ex hid $200,000 in assets, show how those funds should have been divided. If you were defaulted because you were never served, outline what you would have argued about custody, support, or property.
Preparing the Motion
Pull your original divorce paperwork first. You will need both spouses’ full legal names, the case number, and the date the judge signed the decree.
Three documents form the core of the filing:
- The motion itself, which identifies the case, states the legal ground you are relying on, and specifies the relief you want.
- A sworn declaration or affidavit laying out the facts in detail, with supporting evidence attached and labeled as separate exhibits. This is the document that carries your case.
- A proposed order, which some courts require as a draft for the judge to sign if the motion is granted.
Many courts publish standard forms, and even where there is no specific form for a set-aside motion, you can adapt a general motion template. Be specific in the declaration. “My ex hid money” without exhibits will not move a judge. Every factual claim should tie to the legal ground and to a piece of supporting evidence where possible.
Filing and Serving the Motion
Make at least three copies of everything: one for the court, one for your ex-spouse, and one for your records. File the original with the clerk of the court that entered the divorce. Filing fees generally run between $50 and $100. If you cannot afford the fee, ask the clerk for a fee waiver application; courts routinely grant waivers to filers who show financial hardship.
You then have to formally deliver a copy to your ex-spouse through service of process. You cannot hand the papers over yourself. Depending on the jurisdiction, service can be done by a professional process server, a sheriff’s deputy, certified mail, or in some courts, electronic service. Whoever serves the papers completes a proof of service form, which you file with the court. Without that proof on file, no hearing gets scheduled.
The Hearing
Once service is complete and the proof is filed, the court sets a hearing. As the moving party, you present first. Walk the judge through your evidence, identify the legal ground, and show why the outcome would have been different without the problem you identified.
Your ex-spouse then responds, typically arguing that the decree should stand. Expect pointed questions from the bench about whether the evidence actually supports the ground claimed. Judges want specifics. On a hidden-assets motion, expect to be asked exactly what was concealed, how you found it, and why you could not have found it sooner.
The judge either grants or denies the motion. If granted, the decree is vacated and the case reopens so property division, spousal support, and sometimes custody can be relitigated. If denied, the original decree stays in full effect.
What a Set-Aside Actually Does
A successful motion does not erase the divorce entirely. The marriage is not restored in a way that bars a new divorce. What changes is that the terms of the decree, particularly financial provisions, are back in play. The case returns to active status and the court works through the disputed issues with accurate or complete information.
If either spouse has remarried in the meantime, there is a serious complication. Vacating the divorce can mean, technically, that the original marriage was never properly dissolved, which may call the second marriage into question. The consequences vary by state, and some states have “putative spouse” protections for people who remarried in good faith. If remarriage is part of your situation, get legal advice before filing.
Set-Aside Versus Appeal
These two tools address different problems. An appeal argues that the trial judge made a legal error, applied the wrong standard, or abused discretion. Appeals typically must be filed within 30 days of the final judgment and are decided on the existing record, with no new evidence.
A set-aside motion addresses fraud, newly discovered evidence, procedural failures, and the other Rule 60(b) grounds. Deadlines are longer, and new evidence is not only allowed, it is the point. If the problem is how the judge applied the law to the facts presented, appeal. If the problem is that the facts themselves were wrong or incomplete, file to set aside.
Should You Hire an Attorney
Nothing stops you from filing on your own, and the clerk will not reject a self-represented filing. These motions are, however, among the harder family court filings to handle alone. The legal standards are demanding, the evidence requirements are exacting, and a poorly drafted motion can be denied on procedural grounds before the judge reaches the merits. Where significant assets, fraud, or custody are involved, the cost of a lawyer is usually worth it against the risk of losing your one chance to correct the decree. Many family law attorneys offer low-cost or free initial consultations, which can at minimum tell you whether your facts meet the legal threshold before you invest in a filing.
