Being hit by a driver with no insurance — or not enough insurance to cover your losses — puts you in an unusual position. Instead of dealing with the other driver's insurer, you often end up filing a claim against your own policy. That process has its own rules, its own disputes, and its own reasons why attorneys frequently get involved.
Uninsured motorist (UM) coverage is a type of protection you purchase as part of your own auto insurance policy. If you're hit by a driver who carries no liability insurance — or who flees the scene entirely — UM coverage steps in to compensate you for damages that would otherwise have come from the at-fault driver.
A related type, underinsured motorist (UIM) coverage, applies when the other driver has insurance, but their policy limits aren't high enough to cover your full losses. In both cases, you're filing what's called a first-party claim — a claim against your own insurer, not someone else's.
Most states require insurers to offer UM coverage, and many require drivers to carry it. Whether it's mandatory in your state, how much coverage you have, and whether UM and UIM are bundled together or sold separately all depend on your specific policy and where you live.
UM and UIM claims might seem straightforward — your own insurer pays you — but in practice, your insurance company has a financial interest in limiting what it pays out. That dynamic can lead to the same kinds of disputes that arise in third-party claims: disagreements over fault, injury severity, treatment costs, and what your damages are actually worth.
Common friction points include:
Personal injury attorneys become involved in UM/UIM claims for many of the same reasons they appear in any car accident case — but the first-party dynamic adds a layer.
Most attorneys handling these cases work on a contingency fee basis, meaning they take a percentage of whatever is recovered rather than charging upfront. That percentage typically ranges somewhere between 25% and 40%, though it varies by case complexity, state, and whether the case goes to trial. Nothing is collected if there's no recovery.
What an attorney typically handles in a UM/UIM claim:
| Task | Why It Matters |
|---|---|
| Reviewing your policy language | Coverage terms, exclusions, and stacking rules vary significantly |
| Gathering medical records and bills | Documenting the full extent of your injuries |
| Calculating total damages | Including future care, lost earning capacity, pain and suffering |
| Negotiating with your insurer | Your insurer may low-ball early settlement offers |
| Demanding arbitration or filing suit | Many UM/UIM disputes are resolved through arbitration rather than court |
Some UM/UIM policies include mandatory arbitration clauses, which means disputes are resolved outside of court by a neutral arbitrator. Whether that process favors claimants or insurers depends on the arbitration rules, the state, and the specific facts at issue.
UM/UIM coverage is designed to put you in the position you would have been in had the at-fault driver carried adequate insurance. That generally means the same categories of damages available in a standard liability claim:
How these categories are valued, capped, or limited depends heavily on your state's tort system, whether you live in a no-fault state (where PIP coverage handles initial medical costs regardless of fault), and the specific limits of your UM/UIM policy.
UM/UIM claims are subject to statutes of limitations — legal deadlines for filing suit — that vary by state, often ranging from one to six years from the accident date. Critically, some policies also contain their own internal notice requirements and claim-filing deadlines that are shorter than the state statute. Missing either can affect your ability to recover.
The length of a UM/UIM claim varies considerably. Straightforward claims with clear injuries and cooperative insurers may resolve in weeks or months. Claims involving serious injuries, disputed liability, or arbitration can take a year or more.
No two UM/UIM claims work out the same way. The factors that most directly influence how a claim unfolds include:
What an attorney can do for a UM/UIM claimant, how long the process takes, and what a fair outcome looks like are all questions that depend on your state's law, your policy's language, and the specific facts of your accident.
