Uninsured Motorist Lawyer: What Happens When the Other Driver Has No Insurance
By the Editorial Team · Updated August 2026 · 9 min read
Introduction
Being hit by a driver who carries no insurance — or not enough to cover your injuries — leaves you with a hard question: who pays? An uninsured motorist lawyer helps injured drivers pursue their own uninsured/underinsured motorist (UM/UIM) coverage, which functions very differently from a standard third-party injury claim.
This is general information, not legal advice. UM/UIM coverage requirements and claim procedures vary significantly by state, so consult a licensed attorney about your specific policy and situation.
What Is Uninsured/Underinsured Motorist Coverage?
- Uninsured motorist (UM) coverage — pays when the at-fault driver has no liability insurance at all, or fled the scene (hit-and-run).
- Underinsured motorist (UIM) coverage — pays when the at-fault driver’s insurance limits are too low to cover your full damages.
This coverage is part of your own auto policy, and depending on your state, it may be mandatory, optional, or something you must actively decline in writing.
Why These Claims Are Different
Because you’re filing against your own insurer rather than a third party’s, the relationship is more adversarial than it first appears — your insurer still has a financial incentive to minimize the payout, even though you’ve been paying premiums to them. Key differences include:
| Standard Claim | UM/UIM Claim |
|---|---|
| Filed against the at-fault driver’s insurer | Filed against your own insurer |
| Insurer has no ongoing relationship with you | Insurer may use claims history against future premiums |
| Settlement or lawsuit against the driver | Some policies require arbitration instead of a lawsuit |
How a UM/UIM Claim Works
- Report the accident to your own insurer promptly, as most policies require quick notice for UM/UIM claims.
- Document the at-fault driver’s lack of insurance (or their policy limits, for UIM claims).
- Get medical treatment and keep thorough records, just as with any injury claim.
- Submit a demand to your insurer once treatment stabilizes, including full documentation of damages.
- Negotiate with your insurer; many UM/UIM policies require arbitration rather than a courtroom lawsuit if a settlement isn’t reached — check your policy language.
What Compensation Can Cover
- Medical bills, current and future
- Lost wages
- Pain and suffering
- Property damage (in some policies, or through separate collision coverage)
Recovery is generally capped at your UM/UIM policy limits, and for UIM claims specifically, at the difference between the at-fault driver’s coverage and your own UIM limit, depending on your state’s rules (“stacking” rules on multiple vehicles may also apply).
Frequently Asked Questions
Do I have to have UM/UIM coverage?
Requirements vary by state; some mandate it, some require insurers to offer it and let you decline in writing, and some make it fully optional.
What if the at-fault driver fled the scene?
Hit-and-run accidents are typically treated as uninsured motorist claims under most policies.
Can my insurer really fight my own UM/UIM claim?
Yes — even though you’re the policyholder, the insurer still evaluates and can dispute the claim’s value, which is why representation can help.
Will filing a UM/UIM claim raise my premiums?
It’s possible depending on your insurer and state, though rules on this vary and an attorney or agent can clarify your specific policy’s terms.
What if I don’t know my own UM/UIM limits?
Check your policy declarations page, or ask your insurance agent directly — this figure caps what you can potentially recover.
Final Thoughts
UM/UIM claims are easy to overlook because they feel like dealing with “your own” insurer, but they require the same careful documentation and negotiation as any injury claim. A free consultation can clarify your coverage and whether representation would help maximize your recovery.
