Can a Car Accident Claim Be Reopened?

December 19, 2025 | By The Perecman Firm
Can a Car Accident Claim Be Reopened?

A single signature on a single page. In exchange for a check, you signed away your right to future claims, believing the worst was over. It's a moment insurance companies push for, a final, binding end to their responsibility. But what happens when your body doesn't honor that agreement? 

When a "healed" injury requires another surgery, or a "minor" concussion reveals itself as a long-term brain injury? New medical bills quickly consume the financial relief from the settlement, and you're left trapped by a decision you made when you couldn't have known the full story. 

The question of whether a car accident claim can be reopened is one of the most complex in personal injury law, hinging on the immense power of that single signature and the very narrow exceptions that might challenge its finality.

If you have concerns about your settlement, speaking with an NYC car accident lawyer can provide clarity on your legal options.

The final word on final settlements

  • In the vast majority of cases, you cannot reopen a settled car accident claim once you have signed a release form and accepted payment. This document is a legally binding contract.
  • The "release" is the key document. When you sign it, you permanently give up your right to seek any further compensation from the at-fault party for that specific accident.
  • Only in extremely rare circumstances, such as proven fraud or duress, will a court even consider setting aside a settlement agreement.
  • Even if your liability claim against the driver is closed, you might still have options, such as pursuing a claim against a different responsible party or seeking benefits under your own policy.

The Power of the Release Form: The Document That Closes the Door

When you settle a car accident claim, the insurance company does not simply hand you a check. They require you to sign a legal document known as a "Release of All Claims" form. This document is the heart of the settlement. It is a contract, and it is arguably one of the most final legal documents you will ever sign.

Signing the release means you are making a legally enforceable promise. You agree that in exchange for the settlement money, you release the at-fault driver and their insurance company from any and all liability, forever. This includes claims for injuries you knew about, injuries you did not know about at the time, and any future complications that may arise from the accident. 

Attorneys write the language to be intentionally broad to provide maximum protection for the insurer. Once you sign the release and accept the payment, the law considers the case resolved.

Cracking Open a Closed Case: The Rare Exceptions

While the general rule is one of finality, New York law recognizes that there are very limited situations where a contract might be invalid. Proving one of these exceptions is an incredibly difficult legal challenge and requires a high burden of proof. You cannot simply regret the amount you settled for. You must show that the agreement itself was fundamentally flawed from the beginning.

Was there fraud or misrepresentation?

One of the narrowest exceptions involves proving that the insurance company committed fraud to get you to sign the settlement. This means you would have to show that an adjuster intentionally made a false statement about a material fact, you relied on that false statement, and it caused you to accept the settlement. 

A scenario could be an adjuster falsely telling you that your own insurance policy was cancelled, leaving you with no other option for payment. Proving this is extremely difficult.

Were you forced to sign under duress?

Another exception is duress or coercion. This requires you to prove that someone forced you to sign the release against your will through an unlawful threat. The pressure must be so intense that it overcomes your free will. An adjuster being persistent or pressuring you to settle quickly does not meet this high legal standard. Duress involves threats of physical harm or other illegal acts.

A case of "mutual mistake"

In some exceedingly rare cases, a court might challenge a settlement based on a "mutual mistake." This means that at the time of signing, both you and the insurance company were mistaken about a fundamental fact concerning your injuries. The key here is "mutual." If you alone were unaware of the full extent of your injuries, it does not qualify. The mistake must be about the nature of the injury itself, not its future consequences. A situation could be settling a "sprain" case when, unknown to everyone, you actually had a complex fracture.

A court can void a settlement agreement if the person who signed it lacked the legal capacity to enter into a contract. This applies to individuals who were minors (under 18) at the time of signing without court approval, or those who, with proof, were mentally incompetent and unable to grasp the nature and consequences of the document they were signing.

Did You Settle with All Responsible Parties?

This is an important area of inquiry after a settlement. A standard release form only absolves the specific parties named in the document. It is possible that the negligence of more than one person or entity caused your accident. If you only settled with one driver, you may still have a valid claim against another responsible party.

A thorough investigation may reveal that other parties share the blame for your accident. An attorney can help you explore whether any of these other avenues remain open.

  • A third driver involved in a multi-car pile-up.
  • The manufacturer of a defective vehicle part, like faulty brakes or an airbag that failed to deploy.
  • A government entity responsible for a dangerous road condition, like a poorly designed intersection.
  • The employer of the at-fault driver, if they were working at the time of the crash.

If your release only names the at-fault driver, your right to file a claim against a car manufacturer or a municipality might still be intact. You must still adhere to the original statute of limitations for filing such a claim.

Your No-Fault Claim vs. Your Liability Claim

Your No-Fault Claim vs. Your Liability Claim

It is also important to distinguish between the two primary types of claims after a New York car accident. The liability claim is the one you file against the at-fault driver, and this is the one a release closes. The other is your No-Fault or Personal Injury Protection (PIP) claim, which you file with your own insurance company.

Your PIP claim covers your medical bills and a portion of lost wages up to your policy limit (typically $50,000). Closing your liability case does not automatically close your PIP case. You may still be able to submit medical bills for payment under your PIP coverage until those benefits are exhausted.

Your own insurance policy provides these immediate benefits after a car crash. Settling with the other driver's insurance does not prevent you from accessing the remainder of these benefits.

  • Ongoing medical treatments.
  • Physical therapy and rehabilitation.
  • Prescription medication costs.
  • Other necessary and reasonable expenses.

You can continue to seek these benefits until your doctor states you have reached maximum medical improvement or your policy limits are reached.

The Best Defense: Avoiding a Premature Settlement

The most effective way to deal with a bad settlement is to avoid signing one in the first place. Insurance adjusters are trained negotiators whose goal is to close claims for the lowest possible amount. They often try to get injured people to settle quickly, before anyone knows the true nature of their injuries.

The danger of the quick offer

An insurance company that offers a settlement within days or weeks of a crash is not doing you a favor. They are trying to get you to accept a small amount of money before you have had time to consult with an attorney or complete your medical treatment. 

Accepting these quick offers is one of the biggest mistakes an injured person can make.

Reaching maximum medical improvement (MMI)

Maximum medical improvement (MMI)

You should never even consider settling a claim until your doctor declares that you have reached Maximum Medical Improvement (MMI). MMI means your condition has stabilized and is unlikely to improve further with additional treatment. Reaching this point allows you and your doctor to have a clear picture of any long-term or permanent limitations you will have.

Accounting for future damages

A fair settlement must account not just for the bills you have today, but for all the losses you will have in the future. This includes future medical care, future lost wages, and your future pain and suffering. An attorney works with medical and financial experts to project these costs accurately so the settlement demand can include them.

An AI program cannot grasp the binding power of a signed release or the nuances of New York contract law. Relying on an algorithm for guidance on whether you can reopen a car accident settlement may lead to false hope or serious legal errors. 

You need advice from a qualified attorney from The Perecman Firm who can review your specific documents and provide an honest assessment of your situation.

FAQ for Reopening a Car Accident Claim

What if my doctor missed a diagnosis before I settled?

Unfortunately, this usually does not provide grounds to reopen a claim. The broad language in a release form covers all injuries "known and unknown." When you agree to a final settlement, you assume the risk of future or undiscovered injuries.

The insurance adjuster said I could reopen it if I needed to. Does that matter?

A verbal promise from an insurance adjuster is generally unenforceable. The written release form is the legally binding contract. If the document itself does not contain a specific clause allowing you to reopen the claim, any verbal statements to the contrary likely hold no legal weight in court.

How long do I have if I never filed a claim at all?

If you never filed a claim or lawsuit, New York's statute of limitations binds you. For most car accident injury claims, you have three years from the date of the accident to file a lawsuit. If you let this deadline pass, you lose your right to seek compensation forever. You can find more information about New York's auto insurance system from the Department of Financial Services.

If you settled a claim and now believe it was a mistake, you need a straightforward and honest evaluation of your situation. While reopening a closed case is rare, it is worth exploring every possibility.
