Being hit by a driver who has no insurance — or not enough insurance to cover your injuries — puts you in a frustrating position. Your damages are real, but the person responsible can't pay for them. This is exactly the situation uninsured motorist (UM) coverage and underinsured motorist (UIM) coverage were designed to address. But collecting on that coverage isn't always straightforward, and that's where attorneys often enter the picture.
When an at-fault driver has no liability insurance, UM coverage allows you to file a claim with your own insurer to recover compensation for your injuries and, in many states, property damage. UIM coverage applies when the at-fault driver has insurance, but their policy limits are too low to fully cover your losses.
These are first-party claims — meaning you're making a claim against your own policy, not the other driver's. That distinction matters more than many people expect.
| Coverage Type | When It Applies | Who You Claim Against |
|---|---|---|
| Uninsured Motorist (UM) | At-fault driver has no insurance | Your own insurer |
| Underinsured Motorist (UIM) | At-fault driver's limits are too low | Your own insurer |
| Liability (third-party) | You're the injured party, other driver is at fault and insured | Other driver's insurer |
UM/UIM coverage is required in some states and optional in others. Coverage limits, stacking rules (whether you can combine limits across multiple vehicles or policies), and what types of damages are covered vary significantly by state.
Here's the part that surprises many people: your own insurance company can — and often does — dispute your UM/UIM claim. Even though you pay premiums for this coverage, insurers have a financial interest in limiting payouts. Common points of dispute include:
In no-fault states, the rules are different again — your own PIP (personal injury protection) coverage handles medical expenses regardless of fault, and UM/UIM typically comes into play for damages exceeding PIP limits or for more serious injuries meeting a defined tort threshold.
An attorney handling a UM/UIM claim generally takes on several functions that differ from a standard third-party injury case:
Investigating the at-fault driver's insurance status. This involves confirming the driver was truly uninsured or that their limits were insufficient — which requires documentation from the other driver's insurer or a declaration of no coverage.
Reviewing your own policy. Policy language governs everything: what's covered, what the limits are, whether stacking applies, and what procedural steps must be followed. An attorney reads these terms carefully and identifies where the insurer's position may conflict with what the policy actually says.
Building the damages case. Medical records, treatment documentation, lost wage evidence, and expert evaluations of long-term injury impact all feed into how damages are calculated and presented. The stronger the documented record, the harder it is for an insurer to minimize the claim.
Negotiating with your insurer. Because the insurer is both your own company and the opposing party financially, negotiations can become adversarial. Attorneys handle demand letters, counter-offers, and communications in ways designed to preserve legal rights.
Pursuing arbitration or litigation. Many UM/UIM policies require binding arbitration rather than a court lawsuit. Some states give injured parties the option to litigate. An attorney navigates whichever process applies under the policy and state law.
Most personal injury attorneys handle UM/UIM cases on a contingency fee basis — meaning they receive a percentage of any recovery rather than charging upfront. Fee percentages vary, typically ranging from 25% to 40% depending on the state, the stage of the case, and whether it goes to trial. These figures vary; specific arrangements depend on the attorney and jurisdiction.
No two UM/UIM claims follow the same path. The variables that most directly affect outcomes include:
Statutes of limitations — the deadlines for filing a lawsuit — vary by state and can differ for UM/UIM claims versus standard tort claims. Some policies also impose their own internal deadlines for reporting and filing. Missing these windows can affect your ability to recover.
UM/UIM claims sit at the intersection of contract law (your policy), tort law (the other driver's liability), and state insurance regulations — all three of which differ depending on where you live. What an attorney can realistically accomplish, what the insurer is legally required to offer, and what damages are recoverable under your specific policy depend entirely on facts this overview can't assess.
Your state, your coverage, the nature of your injuries, the other driver's status, and the specific language in your policy are the pieces that determine how this actually plays out for you. 🗂️
