The Texas UM/UIM rejection form: why signing it can cost you, and what to do if you already did

Signing that form waives your right to use your own insurance policy to cover your losses when an uninsured or underinsured driver hits you. Most people sign it without understanding what they're giving up.

Here's what the form actually does, why insurers push it, and what your options look like if you signed one years ago and now need the coverage.

What UM/UIM coverage actually covers

Uninsured/underinsured motorist coverage (UM/UIM) sits in your own auto policy. When the driver who hit you has no liability insurance, or has a policy too small to cover your losses, your UM coverage steps in. It pays for medical bills, lost wages, pain and suffering, and other damages you'd otherwise pursue from the at-fault driver directly.

In Texas, about one in eight drivers carries no insurance at all. On I-35 or MoPac on any given day, several of the cars around you have no coverage. If one of them rear-ends you near Ben White and you've waived UM/UIM, your own policy won't fill the gap.

UIM coverage handles the gap between what the at-fault driver's policy pays and what your actual damages are. Say someone with the Texas minimum liability policy ($30,000 per person) T-bones you and your medical treatment costs $90,000. Without UIM, you're left trying to collect $60,000 from an individual who probably can't pay it. With UIM, your own carrier covers the difference up to your policy limits.

You can read more about how these coverage tiers stack against each other in our Texas auto insurance overview.

Why insurers present the rejection form

Texas law requires your auto insurer to offer you UM/UIM coverage at least equal to your liability limits. They have to offer it. They don't have to make it easy to understand.

If you decline the coverage in writing, the insurer is off the hook. The rejection form does exactly that: it documents your written waiver so the carrier doesn't have to pay out on UM/UIM claims.

Insurers present the form at the point of sale, when you're usually focused on getting the policy done and keeping the premium low. The form is short. It doesn't explain in plain language what you're giving up. Many people sign it thinking it's boilerplate, the way you sign acknowledgment forms at a doctor's office.

It is not boilerplate. It's a coverage election with permanent consequences until you revoke it.

What the rejection looks like in practice

The form is typically a single page or a short section inside your policy packet. It says something close to: "I reject uninsured/underinsured motorist coverage under this policy." Your signature goes below that.

Some policies combine UM and UIM on one waiver. Others separate them. You might have rejected both, or just one. If you're not sure what you signed, call your insurer and ask for a copy of your signed rejection form and your current declarations page. Get both in writing, not just a verbal confirmation.

Can you undo a UM/UIM waiver in Texas?

Yes, if you haven't had an accident yet. Texas law allows you to add UM/UIM coverage back to your policy at any time during the policy term. The coverage is not locked in for the full year just because you waived it at inception. Call your insurer or agent, tell them you want to add UM/UIM, and get the endorsement in writing with an effective date.

The coverage will apply to accidents that happen after that effective date. It won't retroactively cover a crash that already occurred.

If you already had an accident and then discovered you signed the waiver

This is the harder situation. A post-accident discovery that you waived UM/UIM coverage does not mean the claim is automatically dead. A few avenues are worth examining.

Did you actually sign the form? Texas courts have held that an insurer must prove a valid written rejection of UM/UIM coverage to deny a claim on that basis. If the insurer can't produce a signed rejection form, or if the form is defective (missing required language, signed by the wrong person, undated), the waiver may not hold. Ask the insurer to produce the exact document. Review it carefully.

Was the waiver obtained properly? The rejection must be an informed, written choice by the named insured. If someone else signed on your behalf without authority, or if the form didn't comply with Texas requirements, there's an argument the rejection is void.

Are there other defendants or policies in play? If the at-fault driver's employer owns the vehicle, a commercial policy might apply. If you were a passenger, the vehicle owner's UM/UIM coverage may be available to you even if your personal policy has been waived. A hit-and-run crash can involve UM coverage through any policy you qualify as an insured under, which sometimes includes household members' policies.

Was the rejection ever revoked? If you renewed your policy and at any point affirmatively re-elected UM/UIM, or if a new policy was issued without carrying over the old rejection, you may have coverage. Every renewal isn't automatic continuation of every election; it depends on how the insurer processed it and how the policies are structured.

None of these arguments work in every case. They require looking at the actual policy language, the rejection form, and the timeline. But they're real arguments that Texas courts have addressed, and they're worth checking before you accept a denial.

Hit-and-run crashes and UM/UIM

A driver who flees the scene is legally uninsured for purposes of your UM claim. If you waived UM coverage and were hit by a driver who fled on East Riverside or South Congress, that waiver is exactly what the insurer will point to when it denies your claim.

Hit-and-run cases also involve a separate procedural requirement in Texas: you generally need to report the crash and, in most policy forms, have a witness other than yourself or contact the police promptly. Our hit-and-run practice page covers those requirements in more detail.

The dollar difference can be significant

Take a real scenario from Travis County. A driver with the minimum 30/60/25 policy runs a red light at Airport and 183 and strikes your car. You're treated at Dell Seton for a fractured wrist, miss six weeks of work, and your total damages come out to $85,000. The at-fault driver's policy pays $30,000. Without UIM, you're owed $55,000 from a driver who has minimum coverage and no significant assets. With UIM at $100,000 limits, your own policy covers the rest.

That's the coverage the rejection form eliminates.

What to do right now if you're unsure what you signed

Pull your declarations page. It will list the coverages you're currently carrying. If UM/UIM doesn't appear with a dollar limit next to it, you likely waived it or it was never offered correctly.

Call your insurer and ask two things: (1) What UM/UIM coverage is on my current policy? (2) Do you have a signed rejection form from me, and can you send me a copy?

If you have no accident pending and want the coverage, add it today. If you've already had an accident and the insurer is pointing to a waiver as the reason for denial, you need someone to look at the actual documents before you accept that answer.

The firm works on a contingency fee. You pay nothing unless there's a recovery.

If the insurer has denied your UM/UIM claim based on a rejection form, or you're trying to sort out what coverage you actually have after a crash in Austin or the surrounding area, Anselmo Aguirre reviews these cases and can tell you whether the waiver holds up and what, if anything, can be done about it.
