The Release That Can Destroy Your Own Claim
This is the most avoidable and most expensive mistake in an underinsured motorist claim: accepting the at-fault driver's limits, signing the release, and only then discovering it has cost you the claim against your own carrier.
Why your insurer cares who you release
If your carrier pays you, it generally acquires the right to pursue the at-fault driver for what it paid. A release you sign extinguishes that right — so policies typically require the insurer's consent before you settle, and settling without it can forfeit the underinsured claim entirely.
The correct sequence
Notify your own insurer of the proposed settlement in writing, before accepting anything. Give it the opportunity to consent or to substitute its own payment. Get the consent in writing, and only then sign.
If it has already happened
Do not assume the claim is dead. Whether a release forfeits coverage depends on the policy language, whether the insurer was prejudiced, and the state. It is worth having reviewed rather than abandoned.
What you can do about it depends on your state
This describes the denial itself, which works much the same everywhere. Whether you can sue under a statute, what you can recover, and how long you have differ sharply — choose the state where your policy was issued.
Common questions
I already signed a release. Is my UIM claim gone?
Not necessarily. It depends on the policy language, whether your insurer was actually prejudiced, and your state. Have it reviewed before assuming.
The other insurer is pressing me to sign this week.
Notify your own carrier in writing first and get consent. A week of delay is far cheaper than forfeiting the underinsured claim.
Is this what happened to you?
A free, confidential review can tell you whether the denial holds up — no cost, no obligation.
Other reasons claims get denied
General information, not legal advice. Insurance law differs by state and every policy is different.
