Can a Lawsuit Be Reopened After Settlement?
Settling a personal injury case can be a major relief, but what happens if you believe the settlement was unfair? Can a lawsuit be reopened after settlement? Our guide may help you understand whether it’s possible to undo a settlement in states like Arizona, California and Colorado.
What Does It Mean When a Case Is Settled?

When a personal injury case is settled, it means both parties have agreed on a resolution without going to trial. Typically, the defendant or their insurance company agrees to pay a specific amount to the plaintiff, and in return, the plaintiff agrees to release the defendant from further liability related to the claim.
Both parties typically sign a settlement document to formalize the agreement. Once this document is signed, it usually closes the case completely and prevents either side from pursuing further claims arising from the same incident.
If a Case Is Settled, Can It Be Reopened?
You can reopen a case if it is settled, but it can be complicated and requires a careful analysis of many legal factors. Settlements are legally binding agreements between the parties in a case. In some situations, the plaintiff may discover new information after settling that could lead to a settled case being reopened.
Can You Undo a Settlement?
Generally speaking, once both parties sign a settlement agreement, it is extremely difficult to undo it. This can be one of the disadvantages of out-of-court settlements. Courts are reluctant to reopen settled cases because the purpose of a settlement is to bring finality to the dispute.
That said, courts in Arizona, California and Colorado may consider setting aside a settlement if it was reached under specific circumstances such as fraud, coercion, duress, misrepresentation or mutual mistake. For example:
- In Arizona, a party may ask the court for relief under Rule 60(b) of the Arizona Rules of Civil Procedure if the agreement was based on fraud or newly discovered evidence.
- In California, a similar request can be made under Code of Civil Procedure §473(b) for mistake, inadvertence or fraud.
- In Colorado, Rule 60(b) of the Colorado Rules of Civil Procedure allows the same type of relief.
These exceptions are limited and require strong proof.
How Do I Reopen a Settlement?

To reopen a settlement, you must show the court a legally recognized reason, such as proof that the other party committed fraud, concealed important facts or misrepresented information.
For example, if you later discover that the defendant or their insurer withheld critical medical or financial information that affected the settlement amount, your personal injury attorney can file a motion to set aside the judgment or settlement under the appropriate state rule.
However, simply regretting the amount you agreed to accept after a settlement is resolved is not a valid reason. Courts will only reconsider a settlement if there is evidence of serious wrongdoing or a procedural error.
How Long Do You Have to Reopen a Settlement?
The time to challenge or reopen a settlement depends on the state and the reason for reopening:
- Arizona: Motions based on fraud, mistake or newly discovered evidence must generally be filed within six months of the judgment or settlement.
- California: You must act within a reasonable time, not to exceed six months after the judgment.
- Colorado: Similar motions must also be made within six months of judgment.
If too much time passes, the court is unlikely to grant relief. Because these deadlines are strict, it’s important to contact an attorney as soon as you suspect your settlement may have been unfair or improper.
Can You Change Your Mind After Accepting a Settlement?
Once you accept a settlement and sign the agreement, you cannot change your mind. The settlement is a binding contract that enforces the terms agreed upon by both parties.
Even if you later believe the amount was insufficient, courts generally will not reopen the case based on dissatisfaction alone. This is why it’s critical to review the agreement carefully, understand how lawyers negotiate settlements and consult your attorney before signing.
Other Legal Options When You Can’t Reopen a Settled Case

If reopening the settlement is not possible, you may still have limited legal options depending on your situation. These include:
- If an insurance company acted dishonestly or failed to handle your claim fairly, you may be able to file a separate insurance bad faith lawsuit.
- If new evidence shows that the other party intentionally deceived you, you may pursue an independent fraud action.
- If your former attorney’s serious mistakes led to an unfair settlement, you may have grounds for a professional negligence claim.
Each of these situations is complex and time-sensitive. An experienced personal injury lawyer can help you determine which option, if any, applies to your case.
