A personal injury claim is the formal process through which someone injured in an accident seeks compensation for their losses. After a motor vehicle accident, that process moves through several distinct stages — each shaped by state law, the insurance coverage involved, how fault is assigned, and the nature of the injuries.
Here's how it generally works.
Most personal injury claims begin with an insurance claim, not a lawsuit. After an accident, the injured person (or their attorney) notifies the relevant insurance company — sometimes their own, sometimes the other driver's, sometimes both.
First-party claims are filed with your own insurer — for example, under Personal Injury Protection (PIP), MedPay, or uninsured/underinsured motorist (UM/UIM) coverage.
Third-party claims are filed against the at-fault driver's liability insurance. This is the more common path when another driver caused the accident.
Which type of claim applies — or whether both apply simultaneously — depends on what state you're in and what coverage each driver carries.
Once a claim is filed, an insurance adjuster is assigned to evaluate it. Adjusters review:
The insurer uses this information to determine how much liability they accept and what they believe the claim is worth. Insurers typically make their own fault determinations, which may or may not align with what the police report says.
Fault rules vary significantly by state and directly affect compensation. There are three main frameworks:
| Fault Rule | How It Works | States That Use It |
|---|---|---|
| Pure comparative negligence | You can recover even if mostly at fault; your percentage of fault reduces your award | CA, NY, FL, and others |
| Modified comparative negligence | You can recover only if below a fault threshold (usually 50% or 51%) | TX, CO, GA, and others |
| Contributory negligence | Any fault on your part may bar recovery entirely | MD, VA, NC, AL, DC |
In no-fault states, your own PIP coverage pays your medical bills and lost wages first, regardless of who caused the accident. To step outside the no-fault system and file a claim against the at-fault driver, your injuries typically must meet a tort threshold — either a monetary amount in medical bills or a specific injury type defined by state law.
Personal injury claims generally seek compensation across several categories:
Economic damages (medical bills, lost wages) are calculated from documentation. Non-economic damages (pain and suffering) are more subjective — insurers and courts use different methods to value them, and outcomes vary widely.
Medical records are central to any personal injury claim. Gaps in treatment or delays in seeking care can complicate how an insurer values injuries. Adjusters look at:
Injuries that require ongoing care, surgery, or result in permanent limitations typically involve larger and more contested claims than those that resolve quickly.
Many claimants handle minor claims directly with insurers. For more complex situations — serious injuries, disputed fault, multiple parties, or low settlement offers — people commonly seek legal representation.
Personal injury attorneys typically work on a contingency fee basis, meaning they receive a percentage of the final settlement or verdict rather than charging upfront. That percentage commonly ranges from 25% to 40%, but it varies by case complexity, whether the case goes to trial, and what state the attorney practices in.
An attorney typically handles demand letters, negotiation with adjusters, gathering of evidence, and if necessary, filing a lawsuit.
Before a lawsuit is filed, the injured person (or their attorney) usually sends a demand letter to the at-fault insurer. This letter outlines the injuries, the treatment received, the damages claimed, and a settlement figure.
The insurer responds — accepting, rejecting, or countering. Most claims resolve through this back-and-forth negotiation without going to court. The timeline can range from a few weeks for straightforward cases to a year or more when injuries are serious, liability is contested, or the claimant is still receiving treatment.
Every state sets a deadline — called a statute of limitations — for filing a personal injury lawsuit. Miss it, and the right to sue is typically lost. These deadlines vary by state and can also vary based on who was involved (e.g., claims against government entities often have shorter notice requirements), the type of injury, and whether the injured person is a minor.
No two personal injury claims follow exactly the same path. How a claim resolves depends on:
The gap between a general understanding of this process and how it applies to a specific accident — in a specific state, with specific coverage and injuries — is where the details that actually matter live.
