Can I Undo a Car Accident Settlement I Signed in Delaware?

New law: Delaware’s settlement-cancellation rule takes effect March 24, 2027. Until then, a signed release is generally final.

Short answer: Right now, usually not. A signed release generally ends your injury claim. Starting March 24, 2027, a new Delaware law will let you cancel a car-accident injury release you signed without a lawyer within 30 days of the crash. You will need to give written notice within 15 days of signing and return the money.

What applies now vs. after March 24, 2027

Until March 24, 2027, Delaware has no law that lets you cancel a car accident settlement after you sign the release. A release is a contract. Once signed, it generally ends your claim against the people it names, even if your injuries turn out to be worse than you expected.

Narrow exceptions exist, and they turn on the specific facts. If you have already signed a release and have doubts about it, talk to a lawyer about your situation.

Starting March 24, 2027, a new section of the Delaware Code, 18 Del. C. § 2322, will give some people a short window to cancel. It will cover only certain early releases, and only if you act quickly.

The new right is not expected to apply to releases signed before the law takes effect. If you signed a release before March 24, 2027, get advice about that release.

What Delaware’s new law (SB 189) says, in plain English

Delaware’s SB 189 created 18 Del. C. § 2322, which takes effect March 24, 2027. From that date, a person hurt in a motor vehicle crash who signs an injury release within 30 days of the crash, without a lawyer, will be able to cancel it within 15 days after signing.

Governor Matt Meyer signed the bill on September 24, 2026, according to the governor’s legislative advisory. The enacted version is Senate Substitute 1 for Senate Bill 189, as amended by Senate Amendment 1. It is 85 Del. Laws c. 522. The bill’s history and synopsis are on the General Assembly’s website.

If you never signed a release, the 15 days run from the day you cashed a settlement check or received an electronic transfer.

The law does not ban early settlement offers. It adds a short window to think again. The bill’s synopsis says the changes “will allow an individual greater ability to make an informed decision.” An earlier version of SB 189 proposed a 60-day window; the final law allows 15 days.

Who the new law covers (and who it doesn’t)

Starting March 24, 2027, the right to cancel will apply only when all three of these are true:

• The release is for injuries from a motor vehicle accident.
• You signed it within 30 days of the crash.
• No lawyer was helping you when you signed, and you had not hired one or given one power of attorney.

If a lawyer was helping you when you signed, the new right does not apply. Talk to that lawyer about the release.

Some situations are not addressed in the law’s text. It doesn’t say how the rule applies to a settlement only for vehicle damage, a release signed by a parent or for an estate, or a settlement with your own insurance company, such as an uninsured or underinsured motorist claim. If one of these fits your situation, get advice before you rely on the new law.

How to cancel a release under § 2322 (step by step)

Once the law takes effect on March 24, 2027, cancelling a qualifying release will work like this:

1. Check that you qualify. The release covers an injury claim from a motor vehicle accident, you signed it within 30 days of the crash, and you had no lawyer helping you. (§ 2322(a))
2. Act within 15 days of signing. If you never signed a release but cashed a settlement check or received an electronic payment, count 15 days from the cashing or transfer. (§ 2322(a))
3. Put it in writing. Send a written notice of rescission to the person you released, or to their lawyer or insurance company. (§ 2322(b)(1))
4. Return the money. Send back any check or settlement money you received. (§ 2322(b)(2)) If you think you might cancel, don’t spend the money.
5. Send it in a way you can prove. The law lists certified mail, a certificate of mailing, an ACH tracking number, or another recognized way to track funds. (§ 2322(b)(3))
6. Keep copies of the release, your notice, your proof of mailing, and your proof that the money was returned.
7. Expect a hold on future payments. The insurer may hold back any future settlement payment until it confirms the money came back. (§ 2322(c))

The release must tell you about this right

Starting March 24, 2027, a release signed within 30 days of a Delaware crash will have to tell you about your right to cancel it. Under § 2322(d), the notice must be “stated conspicuously and separately” on the release or the settlement check. If there is no release or check, the notice must come to you in writing.

Look for that notice. If you don’t see it, ask about it before you sign.

If an adjuster is pressing you to settle now

These steps apply today and after March 24, 2027:

1. You don’t have to decide on the call. Ask for the offer and the release in writing.
2. Get medically evaluated and follow your provider’s advice before you decide. Some injuries take time to show their full extent.
3. Read what the release gives up. Releases often cover all claims from the crash, known and unknown.
4. Know that PIP is separate. Your own PIP coverage generally pays covered medical bills and lost earnings first, regardless of fault. See How Does Delaware No-Fault PIP Work After a Crash?
5. Be careful with the check. Cashing a settlement check can matter legally. Under the new law, if no release was signed, the 15-day window runs from the cashing.
6. Write down the dates: the crash, the offer, and any signing. The new law’s windows are short.
7. Talk to a lawyer before you sign, not after. A free review can help you understand what you’d be giving up.

This 15-day window is not your lawsuit deadline

Delaware’s new 15-day cancellation window and its deadline to file an injury lawsuit are two different clocks. The cancellation window is counted in days. The lawsuit deadline is generally two years from the injury, under 10 Del. C. § 8119.

Cancelling a release doesn’t pause or extend the two-year clock. If you cancel and still want to pursue the claim, keep that deadline in mind. For more, see What Is the Deadline to File a Delaware Car Accident Injury Lawsuit?

Does my case count?

No one can answer that honestly without the facts. In general, a Delaware crash is worth a review when three things are true:

• You were hurt or had real losses from the crash.
• Someone else’s carelessness may have caused it, at least in part.
• The harm is enough to look at closely, such as medical treatment, missed work, or pain that has not gone away.

A review is not a promise of a case or a result. For more on how these claims work, see our Delaware car accident lawyers page.

Frequently asked questions

Can I undo a car accident settlement I signed in Delaware?

It depends on when you signed. Today, a signed release is generally final. Starting March 24, 2027, 18 Del. C. § 2322 will let you cancel a car-accident injury release you signed without a lawyer within 30 days of the crash, if you send written notice within 15 days of signing and return the money. Get advice about any release signed earlier.

What is Delaware SB 189?

SB 189 is the bill that created Delaware’s right to cancel certain early car-accident injury releases. The enacted version, Senate Substitute 1 as amended, was signed on September 24, 2026, as 85 Del. Laws c. 522. It added 18 Del. C. § 2322, which takes effect March 24, 2027. An earlier draft proposed 60 days; the final law allows 15.

How long will I have to cancel a release under the new law?

Fifteen days after you sign it, once the law takes effect on March 24, 2027. If you never signed a release but cashed a settlement check or received an electronic payment, the 15 days run from the cashing or transfer. The law covers only releases signed within 30 days of the crash. Don’t wait until the last day.

How do I cancel a car accident release in Delaware?

Starting March 24, 2027, under 18 Del. C. § 2322(b), you send a written notice of rescission to the person you released, their lawyer, or their insurance company, and return any check or settlement money you received. Send both in a way you can prove, such as certified mail or a tracked funds return, and keep copies.

Do I have to give the settlement money back?

Yes. Under the new law, returning any check or settlement money is a condition of cancelling (§ 2322(b)(2)). The insurer may also hold back any future settlement payment until it confirms the money came back. If you think you might cancel, don’t spend the money.

Does the new law apply if I had a lawyer?

No. Once it takes effect, it covers only releases signed without the assistance or guidance of a lawyer, and without a power of attorney to, or an employment contract with, a lawyer. If a lawyer was helping you when you signed, talk to that lawyer about the release and your options.

Will the release have to tell me I can cancel it?

Yes, starting March 24, 2027, for releases signed within 30 days of the crash. Under § 2322(d), the release or settlement check must state the right to rescind conspicuously and separately. If there is no release or check, you must be told in writing. If you don’t see the notice, ask before you sign.

Does cancelling a release change my two-year deadline to sue?

No. The 15-day cancellation window is separate from Delaware’s lawsuit deadline, which is generally two years from the injury under 10 Del. C. § 8119. Cancelling a release doesn’t pause or extend that clock. If you cancel and still want to pursue the claim, keep the two-year deadline in mind.
