How to File a Personal Injury Insurance Claim, Step by Step

To file a personal injury insurance claim, you notify the at-fault party's insurer (and often your own) as soon as possible, open a claim file, document the accident and your injuries thoroughly, cooperate carefully with the adjuster assigned to your case, and submit organized proof of your damages before any settlement demand — all while watching the clock, since states set a deadline for filing a lawsuit if the claim doesn't resolve. The process is largely the same whether it's a car crash, a slip-and-fall, or another type of accident, though the specific insurer and paperwork will differ.

The basic idea behind a claim

An insurance claim is a request for the insurance company to pay for the harm its policyholder caused (or, if it's your own insurer, harm covered under your policy). Under the negligence rules that apply in most personal injury cases, you generally need to show four things: the other party owed you a duty of care, they breached it, that breach caused your injury, and you suffered actual damages (medical bills, lost wages, pain and suffering, etc.). Insurance adjusters evaluate claims with these same elements in mind, so the stronger your documentation on each point, the stronger your claim.

Most personal injury claims never go to trial — the large majority settle directly with an insurer or after a lawsuit is filed but before a verdict. That doesn't mean the process is casual; insurers are businesses that profit by paying out as little as possible, so how you handle the early steps matters.

What to do: the claim process step by step

1. Get medical care first. See a doctor promptly, even if you feel "okay." A documented medical evaluation close in time to the incident is some of the most persuasive evidence you have, and gaps in treatment are one of the first things adjusters use to argue an injury wasn't serious or wasn't caused by the incident.
2. Notify the right insurer(s) quickly. Most policies require "prompt" or "reasonably timely" notice, and some auto policies set a specific number of days for reporting — don't guess at your policy's deadline, read it or call and ask. Depending on the situation you may need to notify: the at-fault party's liability insurer, your own auto insurer (for med-pay or uninsured/underinsured motorist coverage), a property owner's insurer (for a fall), or a homeowner's/renter's policy.
3. Open the claim and get a claim number. When you call, give basic facts (date, location, parties involved) but avoid narrating a detailed, recorded account of fault or injuries at this stage — save the details for a written, reviewed statement. Write down the claim number, the adjuster's name, direct phone number, and email.
4. Document everything, starting immediately.
   • Photos/video of the scene, vehicle damage, hazard (wet floor, broken step, etc.), and visible injuries.
   • Names and contact information of witnesses.
   • A copy of the police report or incident report (ask the property manager/store for an incident report number if there's no police involvement).
   • A dated symptom/pain journal — what hurts, how it limits daily activities, work missed.
   • Every medical record, bill, and receipt for related expenses (prescriptions, mileage to appointments, medical devices).
   • Pay stubs or a letter from your employer documenting missed work and lost income.
5. Deal with the adjuster deliberately. The adjuster's job is to evaluate — and often minimize — the payout. It's fine to be polite and cooperative, but:
   • Don't give a recorded statement to the other side's insurer without thinking it through first (you're generally not obligated to give one to them, only to your own insurer under your policy's cooperation clause).
   • Don't speculate about fault percentages or guess at facts you're unsure of.
   • Don't discuss your injuries in terms of how you feel "today" if you're still recovering — describe the full course of treatment instead.
   • Get any promises, extensions, or agreements in writing or follow up by email confirming what was said on the phone.
6. Finish treatment before you value the claim. You generally shouldn't estimate a settlement demand until you've reached maximum medical improvement or your doctor can reasonably project future treatment needs — settling too early can mean you release the claim for less than ongoing or future costs actually turn out to be.
7. Assemble your proof of damages (demand package). This typically includes an itemized list of medical bills and records, proof of lost income, out-of-pocket expenses, photos, and a written narrative connecting the incident to your injuries and losses. Many people also seek pain-and-suffering compensation, which doesn't have a receipt but is supported by your medical records, journal, and how the injury affected your life.
8. Submit a demand letter and negotiate. The demand typically states the facts, liability, injuries, treatment, damages, and a requested settlement amount. Expect the insurer's first offer to be lower than the demand; negotiation is normal. Respond to counteroffers in writing and keep a record of the back-and-forth.
9. Decide whether you need a lawyer. Many personal injury attorneys work on contingency, commonly around one-third of the recovery (the exact percentage and how costs are handled varies by firm and by state rule, so ask before signing). A lawyer is worth considering for serious injuries, disputed fault, lowball offers, or claims against a government entity, which often have very short special notice deadlines.
10. Track the deadline to sue. If the claim doesn't settle, you may need to file a lawsuit before your state's statute of limitations expires. This deadline varies significantly by state and by the type of claim (and can be dramatically shorter — sometimes just months — for claims against a city, county, or state government). Confirm the specific deadline for your state and situation with your state's courts or an attorney; don't rely on a number you saw online, including this one.

What NOT to do

• Don't post about the accident, your activities, or your recovery on social media — insurers routinely review it and use it to dispute injury claims.
• Don't sign a medical release or settlement release without understanding exactly what records it covers and what rights you're giving up.
• Don't accept a quick first offer before you know the full extent of your injuries and future treatment needs.
• Don't miss appointments or stop treatment early — gaps get used against you.
• Don't assume a delay by the insurer means the deadline to sue is also delayed; the statute of limitations generally keeps running regardless of ongoing negotiations.

Comparative and contributory fault

If you were partly at fault, most states reduce your recovery by your percentage of fault (comparative negligence), while a small number of states bar recovery entirely if you bear any fault (contributory negligence). Which rule applies — and how it's calculated — depends on your state, so don't assume shared fault automatically kills or shrinks your claim by a specific amount; confirm the rule that applies where the incident happened.

Taxes and settlements

Compensation for physical injuries or physical sickness is generally excluded from federal taxable income under 26 U.S.C. § 104(a)(2), though portions allocated to things like punitive damages or interest are typically still taxable.
