Filing an auto insurance claim is how you formally notify an insurance company — yours or someone else's — that a covered loss has occurred and that you're seeking compensation. The process sounds straightforward, but what happens after you file depends heavily on your state's laws, the type of coverage involved, who was at fault, and the nature of the damages.
The first decision point is which insurance company you're filing with.
A first-party claim is filed with your own insurer. You'd do this if you have collision coverage and want your car repaired regardless of fault, or if your state requires you to use your own Personal Injury Protection (PIP) coverage first for medical expenses.
A third-party claim is filed with the at-fault driver's liability insurance. This is how most injury and property damage claims work in at-fault states, where the driver who caused the accident — or their insurer — is responsible for compensating others.
| Claim Type | Filed With | Common Reason |
|---|---|---|
| First-party | Your own insurer | Collision, comprehensive, PIP, MedPay, UM/UIM |
| Third-party | At-fault driver's insurer | Liability for injury or property damage |
Once a claim is submitted, an insurance adjuster is assigned to investigate. Their job is to evaluate the facts, assess damages, and determine how much — if anything — the insurer is obligated to pay.
The adjuster will typically:
How long this takes varies. Minor property-damage-only claims can resolve in days. Claims involving serious injuries, disputed fault, or multiple vehicles can take months — sometimes longer if litigation becomes involved.
Fault determination isn't always clean. Most states use some form of comparative negligence, meaning fault can be split between parties. Under pure comparative negligence, you can recover damages even if you're mostly at fault — though your payout is reduced by your percentage of fault. Under modified comparative negligence, there's typically a cutoff (often 50% or 51%) beyond which you can't recover anything.
A small number of states still follow contributory negligence rules, which can bar recovery entirely if you're found even slightly at fault.
No-fault states work differently. Regardless of who caused the accident, each driver first turns to their own PIP coverage for medical expenses and lost wages. The ability to step outside the no-fault system and sue the at-fault driver typically depends on meeting a tort threshold — either a dollar amount of medical expenses or the presence of a serious injury, depending on the state.
Economic damages are measurable losses:
Non-economic damages include pain and suffering, emotional distress, and loss of enjoyment of life. These are harder to quantify and are evaluated differently by insurers and courts depending on the state and the severity of the injuries.
Some states cap non-economic damages in certain cases. Others don't. The type of accident and coverage involved also shapes what's available.
| Coverage Type | What It Generally Covers |
|---|---|
| Liability | Injuries/damage you cause to others |
| Collision | Your vehicle, regardless of fault |
| PIP / MedPay | Medical expenses, sometimes lost wages |
| Uninsured/Underinsured (UM/UIM) | When the at-fault driver has no or insufficient coverage |
| Comprehensive | Non-collision losses (theft, weather, animals) |
Coverage limits — the maximum an insurer will pay — are set in your policy. If damages exceed those limits, recovering the difference can become complicated, especially if the at-fault driver has limited assets.
How and when you seek medical care matters to the claims process. Treatment records create a documented link between the accident and your injuries. Gaps in treatment — waiting weeks to see a doctor, stopping care early — are frequently used by insurers to question the severity of injuries or whether they're accident-related.
Emergency care, follow-up visits, specialist referrals, physical therapy, and imaging studies all generate records that adjusters and attorneys use to evaluate injury claims. Medical liens may also come into play if a provider agrees to defer payment until the claim settles.
Personal injury attorneys typically work on a contingency fee basis, meaning they take a percentage of the final settlement or court award rather than charging upfront. That percentage varies but is often in the range of 25–40%, depending on the state, the complexity of the case, and whether it goes to trial.
Attorneys are commonly involved when injuries are serious, fault is disputed, the insurer's offer seems inadequate, or the claim involves long-term medical care. Legal representation changes the dynamic of negotiations and can affect how claims are structured and valued — though outcomes still vary by case.
Depending on the state and severity of the crash, there may be requirements beyond the insurance claim itself:
Statutes of limitations — the deadlines for filing a lawsuit — vary by state and by the type of claim (personal injury vs. property damage). Missing these deadlines typically extinguishes the legal right to sue, regardless of the merits.
Every element of a claim — what you can recover, how long it takes, whether you file with your insurer or someone else's, whether an attorney is needed — depends on the specific combination of your state's laws, your policy's terms, who caused the crash, and what happened to you.
That combination is different for everyone.
