Can You Reopen a Tempe Car Accident Claim After Accepting a Settlement?

July 29, 20254 min read

When you’re injured in a car accident in Tempe, it’s natural to want closure. Medical bills, missed work, and insurance pressure can push many people into accepting a settlement faster than they’d like. But what happens when new injuries appear—or you realize that the settlement wasn’t enough?

It’s a question many crash victims face after signing on the dotted line. Unfortunately, once you accept a settlement and release the claim, reopening it is rarely an option. Still, there are some limited exceptions. The Tempe car accident attorney team breaks down what you need to know if you're having second thoughts after resolving your claim.


The Power of a Release Form

Almost every car accident settlement includes a release of liability. When you sign this document, you’re agreeing to give up any future claims against the at-fault party and their insurer related to that accident. This release is legally binding—even if you later discover new injuries, complications, or costs.

That’s why insurance companies often push for fast resolutions. They know the full extent of your damages may not be clear in the first few days or weeks after a crash. In many cases, especially when soft tissue injuries or symptoms of a traumatic brain injury take time to develop, the true impact of the collision only becomes clear much later.


Exceptions to the Rule: When Reopening Might Be Possible

While reopening a settled claim is generally not allowed, there are a few narrow circumstances where it could happen:

1. Fraud or Misrepresentation
If the insurance company or other party made false statements or withheld critical information during the negotiation process, you may have grounds to challenge the settlement. For example, if they intentionally misrepresented coverage or fabricated evidence, it could open the door to legal remedies—even after the claim is settled.

2. Administrative or Clerical Errors
If there was a mistake in the documentation—such as releasing the wrong party, omitting key terms, or a misunderstanding about what was being settled—there may be a limited opportunity to correct the issue. This would typically require legal action and supporting documentation.

3. Multiple Parties Not Named in the Release
If your original settlement only applied to one party (like a driver), but you later discover another liable party—such as a rideshare company, vehicle manufacturer, or municipal agency—you may still be able to pursue claims against the newly identified party.

These scenarios are rare and typically require extensive documentation, timing, and legal support.


Why You Shouldn’t Rush Into a Settlement

One of the most common regrets Tempe crash victims face is settling before the full scope of their injuries or financial impact is known. Insurance companies often offer quick settlements to close claims cheaply, but that speed comes with risk. You may not know yet whether your back pain is a temporary strain or the onset of a more serious condition like degenerative disc aggravation.

Additionally, if you haven’t finished medical treatment—or if your doctor anticipates future care—you could be left covering those expenses out of pocket once the settlement is finalized.

It’s especially risky to accept a settlement too early in crashes that involve hit-and-run drivers, uninsured motorists, or multi-vehicle accidents, where additional evidence may surface later.


What to Do If You Regret Accepting the Settlement

If you already signed a release but believe there’s been fraud or some form of mistake, your first step should be to gather all documentation related to your claim. This includes:

  • A copy of the release form you signed

  • Any correspondence with the insurance company

  • Your medical records and treatment history

  • Evidence of newly discovered injuries or damages

From there, it may be possible to have the settlement reviewed for irregularities. But be realistic—most releases hold up in court unless a very strong legal basis exists for overturning them.


Avoiding the Trap: Get the Full Picture First

It’s far easier to avoid the problem than fix it after the fact. To protect yourself before settling a Tempe car accident claim, make sure to:

  • Complete all medical treatment or reach maximum medical improvement

  • Understand your prognosis and potential long-term limitations

  • Calculate lost wages and potential lost earning capacity

  • Account for future care, therapy, or surgery

  • Get multiple repair quotes if property damage is involved

  • Confirm whether there are additional parties who may be liable

Doing your homework up front can prevent regret later—and keep you from being stuck with unexpected bills after the check is cashed.


Final Thoughts

Once you’ve accepted a settlement for a Tempe car accident and signed a release, reopening that claim is extremely difficult. While there are exceptions for fraud, clerical errors, or unknown parties, these are not the norm. Most people are bound by the agreement, even if their injuries worsen or costs rise later.

That’s why taking your time before signing anything is critical. Insurance companies want quick resolutions—but that speed can cost you. Don’t rush the process. Make sure you’ve fully documented your injuries, understand your prognosis, and have considered the long-term financial impact.

If you’re unsure about your next step, reviewing your situation with someone who understands Arizona personal injury law—even if they’re not a lawyer—can provide helpful insight. Because once that settlement is signed, there’s usually no turning back.
