Can a Car Accident Claim be Reopened?

Generally, once you settle a car accident claim and sign the final paperwork, it is very difficult to reopen it. That signed agreement, usually called a release, is a legally binding contract that closes your case for good. However, in very rare and specific circumstances, there might be a path to challenge a settlement, but it is an uphill battle.

If you’re reading this, you may be feeling that the settlement you accepted doesn’t truly cover the harm you’ve suffered, and you are right to seek answers about your options.

Key Takeaways

  • Signing a “release of all claims” form typically prevents a car accident claim from being reopened. This document is a final, legally binding contract.
  • Reopening a settled claim is only possible in very limited situations, such as when there is evidence of fraud, misrepresentation, or a mutual mistake of fact by both parties.
  • A settlement might be challenged if the person who signed it lacked the mental capacity to understand the agreement due to injury or medication.
  • Even if a settled claim cannot be reopened, other legal options might exist, such as pursuing a claim against a different at-fault party not named in the original release.
  • Missouri has strict deadlines, known as statutes of limitations, for filing legal actions, which can affect any attempt to revisit a settlement.

Understanding the Finality of a Car Accident Settlement in Missouri

Small car model on wooden desk with judge's hammer.After weeks or even months of back-and-forth with an insurance company, receiving a settlement offer can feel like a lifeline. The thought of paying off medical bills and putting the accident behind you is powerful. In exchange for that settlement check, the insurance adjuster will ask you to sign a document, often titled a “Release of All Claims.” It’s crucial to understand what this document really means.

A release is a legal contract. By signing it, you agree to give up your right to seek any more money from the at-fault party or their insurance company for any injuries or damages related to that specific accident, forever. This includes compensation for things you know about and things you don’t.

Think of it like this: if you sell your car to someone and sign over the title, you can’t go back a month later and ask for more money because you decided it was worth more. The deal is done. An insurance release works the same way. It provides certainty for the insurance company, ensuring they won’t be surprised by another claim from you years down the road. They are written by their lawyers to be ironclad, protecting their interests by making the settlement final.

When Can a Car Accident Claim be Reopened? Exploring the Limited Exceptions

While the general rule is that a settled claim is a closed claim, Missouri law recognizes that some agreements aren’t made fairly. The law provides a few very narrow exceptions that could, in theory, allow a settlement to be undone. Proving these exceptions is extremely challenging and requires significant evidence.

Was There Fraud or Misrepresentation?

One of the primary exceptions is fraud. This is more than just feeling like you got a low offer. Fraud in this context means the insurance company intentionally lied about a critical fact to trick you into signing the settlement agreement.

To prove fraud, you typically need to show:

  • The insurance adjuster made a statement that was false.
  • They knew the statement was false when they made it.
  • They made the false statement with the intent to deceive you into settling.
  • You relied on that false statement when you decided to accept the offer.

An example could be an adjuster telling you that the at-fault driver’s policy limit is only $25,000 when it is actually $250,000, causing you to accept a much lower amount. Proving their intent is the hardest part, as they can often claim it was a simple mistake.

Did You Lack the Mental Capacity to Sign?

A contract is only valid if both parties have the “capacity” to understand what they are agreeing to. This means you must be of sound mind and understand the consequences of your signature. If you signed the release while you were unable to comprehend its meaning, the agreement might be voidable.

Situations where capacity could be questioned include:

  • You were under the influence of powerful pain medications after a surgery.
  • You had a severe head injury from the crash, like a traumatic brain injury (TBI), that impaired your judgment.
  • You were a minor at the time of the settlement without proper court or parental approval.

If an adjuster pressures you to sign paperwork in your hospital room just hours after a serious crash on I-55, that could be a situation where your capacity to make a rational decision is questionable.

Was the Agreement Based on a Mutual Mistake?

This is another rare and complex exception. A mutual mistake happens when both you and the insurance company base your settlement on a critical fact that you both believed to be true, but which was later proven to be completely wrong. It cannot be a mistake in judgment or a simple unknown injury.

The mistake must be about a fundamental fact that was the foundation of the agreement. For instance, if both parties agreed to a settlement believing your only injury was a broken arm, but it was later discovered through advanced imaging that you also had a severe spinal injury that existed at the time of the settlement but was undetectable, there might be grounds for a mutual mistake. However, if you simply developed a new pain later, that is generally considered a risk you accept when you sign the release.

These exceptions are difficult to prove, but exploring them with knowledgeable legal counsel is the only way to know if they might apply to your situation.

The Difference Between Reopening a Claim and Other Legal Actions

Sometimes, feeling trapped by a settlement isn’t about undoing the agreement you signed but about realizing there are other avenues for justice you didn’t know existed. Your signed release is specific. It usually names the exact driver and insurance company you are releasing from liability. It may not close the door on all possibilities.

Pursuing a Claim Against a Different At-Fault Party

Alphabet letter block in word letter block on wood backgroundMany accidents, especially those involving commercial trucks or complex intersections like those in Cape Girardeau or Sikeston, have more than one responsible party. Your settlement with the other driver’s insurance company does not prevent you from pursuing a claim against someone else whose negligence contributed to your injuries.

Other potential at-fault parties could include:

  • A Vehicle Manufacturer: If your injuries were made worse by a defective airbag or a seatbelt that failed, you might have a product liability claim.
  • A Government Entity: If a poorly maintained road or a broken traffic signal was a factor in the crash, the city or state could hold some responsibility.
  • A Third Driver: In a multi-car pileup, you might have settled with one driver, but another driver may also be at fault.

A careful review of your accident report and the release you signed can reveal if claims against other parties are still possible.

Filing a Vexatious Refusal to Pay Claim

This type of claim isn’t against the other driver; it’s a separate legal action against your own insurance company. In Missouri, this most often applies when you make a first-party claim—such as a claim on your Uninsured or Underinsured Motorist (UIM) coverage—and your insurer refuses to pay without a reasonable cause.

This action is governed by Missouri Revised Statutes section 375.420, which addresses an insurer’s “vexatious refusal to pay.” If your insurance company unreasonably and without good cause denies or delays paying your valid claim, you may be able to sue them. This lawsuit is separate from the original accident case and focuses entirely on the insurance company’s improper conduct in handling your claim.

Why You Might Feel Your Settlement Was Unfair

It’s an incredibly common and valid feeling. You trusted the process, took the offer you thought was fair at the time, and tried to move on. Now, reality has set in, and the money is gone or simply isn’t enough. The reasons for this feeling of regret are often heartbreakingly similar.

  • Undiscovered or Worsening Injuries: The most common reason is medical. What felt like simple whiplash has turned into chronic neck pain requiring injections. A “sore knee” now needs surgery. The full extent of injuries from a car accident can take weeks or even months to become clear, long after a quick settlement has been signed.
  • The True Financial Impact: You may not have realized how much work you would have to miss. The settlement covered your initial emergency room visit, but not the months of physical therapy or the cost of modifications to your home.
  • Pressure from an Insurance Adjuster: Adjusters are trained to settle claims quickly and for the lowest amount possible. They might have been friendly, but their job is to protect their company’s bottom line. Many people feel rushed into a decision, accepting an offer before they truly understand their prognosis or long-term needs.
  • Unforeseen Emotional and Mental Toll: The settlement may not have accounted for the ongoing anxiety, PTSD, or depression that followed the traumatic event. The impact on your quality of life is a real, compensable damage that is often overlooked in early, unrepresented settlements.

These feelings of regret are completely understandable and highlight the risks of settling a claim without a full picture of your future.

Missouri’s Statute of Limitations and Its Impact

Statute of limitations (SOL) on a court desk.Even if you believe one of the rare exceptions applies to your case, you must still act within a strict legal time frame known as the statute of limitations. This is a law that sets a deadline for how long you have to file a lawsuit after an incident.

In Missouri, the statute of limitations for most personal injury claims is five years from the date of the accident, as outlined in Missouri Revised Statutes section 516.120. If you discover evidence of fraud five and a half years after your crash, you will likely be barred from taking any legal action, no matter how strong your case is. This deadline makes it incredibly important to act quickly if you feel your settlement was unjust. Waiting could mean losing your rights for good.

FAQ for Reopening a Car Accident Claim

Here are answers to some common questions that arise when people are considering their options after a settlement.

What if my doctor finds a new injury that is related to the accident after I settled?

Unfortunately, this is one of the main reasons that release agreements are considered final. The language in these documents almost always states that you are releasing claims for all injuries, “known and unknown.” Unless you can prove a specific exception like fraud or mutual mistake about the injury’s existence at the time of signing, the discovery of a new or worsening injury is generally not enough to reopen a claim.


Does cashing the settlement check close my case forever?

Cashing the check is the final step in accepting the agreement. It signifies your acceptance of the contract. In almost all cases, once you have signed the release and cashed the check, the insurance company will consider the matter permanently closed.


Can I reopen a claim just because the insurance adjuster was rude or used high-pressure tactics?

While unfair pressure is a serious concern, being rude or persistent is not usually enough to invalidate a settlement agreement on its own. However, if the pressure was so extreme that it contributed to you signing while you lacked the mental capacity to understand—for example, in a hospital bed while on heavy medication—it could be a contributing factor in a legal challenge.
