To file a claim for injury compensation, you document your injuries and the circumstances that caused them, identify who is legally responsible, and send that party’s insurance company a written demand for payment supported by your evidence. Most claims resolve through negotiation with the insurer. If negotiation fails, you file a lawsuit before your state’s deadline expires. The quality of your documentation and your awareness of filing deadlines determine almost everything about the outcome.
What to Do in the First Days
The first hours and days after an injury shape the claim more than most people realize. Adjusters and defense attorneys will later comb through this window looking for gaps.
See a doctor right away, even if you feel fine. Concussions, internal bleeding, and soft-tissue injuries often take hours or days to produce symptoms, and a delay in treatment gives the other side room to argue your injuries weren’t serious or weren’t caused by the incident. The emergency room or urgent care record is the first link in the chain tying your injuries to what happened.
At the scene, or as soon as you’re able, photograph everything: the location, any property damage, road or floor conditions, visible injuries, and anything else that tells the story. Collect names and phone numbers from witnesses. File an official report with the appropriate authority: police for a traffic collision, your employer for a workplace injury, the property owner or manager for a fall on someone else’s premises. Those reports carry weight your own account cannot.
Know Your Filing Deadline
Every state sets a deadline for filing a personal injury lawsuit, and missing it almost always kills the claim no matter how strong the evidence is. Deadlines typically run from one to six years from the date of the injury, with two or three years being the most common. The clock usually starts the day the injury occurs. Many states apply a discovery rule for injuries that aren’t immediately apparent: the deadline begins when you knew or reasonably should have known you were hurt and that someone else may have caused it.
Claims against government entities carry much shorter deadlines that catch people off guard. For injuries caused by a federal employee acting in the course of their job, you must file a written administrative claim with the responsible federal agency within two years, and you cannot file a lawsuit until the agency denies the claim in writing or fails to respond within six months.1Office of the Law Revision Counsel.

United States Code Title 28 – 2675 Disposition by Federal Agency as Prerequisite State and local government claims often require written notice within 90 to 180 days of the injury, far shorter than the general statute of limitations, and missing that notice window can bar your claim entirely.
Find out which deadline applies to your situation before you do anything else. Everything else in the process assumes you still have the right to sue.
Build the Evidence File
Strong claims are built on documentation, not memory. Start assembling your file early and keep adding to it.
- Medical records: emergency room reports, doctor’s notes, imaging results, surgical records, therapy logs, and every bill. These establish what injuries you sustained, how they connect to the incident, and what treatment has cost or will cost.
- Income documentation: pay stubs, W-2 forms, tax returns, and a letter from your employer confirming missed days and your normal compensation. If you’re self-employed, your federal tax return with Schedule C and business accounting records serve the same purpose.
- Incident reports: police reports, workplace incident reports, or property inspection records created at or near the time of the event.
- Witness statements: written or recorded accounts from people who saw what happened.
- Photographs and video: images of the scene, your injuries taken over time as they develop, and any hazardous conditions that contributed.
- A personal journal: daily notes about pain levels, limitations, emotional state, and how the injury is affecting your routine. A contemporaneous record is far more persuasive than trying to recall these details months later.
While your claim is active, be careful what you post online. Insurance adjusters routinely check claimants’ social media. A photo at a birthday party can be twisted into evidence that your back injury isn’t limiting you. A check-in at a gym, even if you only went to sit in the sauna, can be presented out of context. Tighten your privacy settings and assume anything you post will be screenshot and handed to a defense attorney.
Figure Out What the Claim Is Worth
Injury claims seek two broad categories of compensation. Economic damages cover losses you can put a receipt on: medical bills past and future, lost wages, and reduced earning capacity if the injury limits the kind of work you can do going forward. Non-economic damages compensate for physical pain, emotional distress, loss of enjoyment of daily activities, and the broader impact on your life. Non-economic damages are harder to quantify, and they’re where most of the disagreement with insurance companies happens.
In rare cases involving deliberate harm, fraud, or reckless disregard for safety, a court may award punitive damages on top of compensatory damages. Simple negligence is not enough to trigger them.
Your own share of fault matters too. Most states follow some form of comparative negligence, which reduces your recovery by whatever percentage of fault is assigned to you. If you’re found 20 percent at fault on $100,000 in damages, you recover $80,000. Over 30 states use modified comparative negligence, which bars recovery entirely once your share hits 50 or 51 percent, depending on the state. About a dozen states use pure comparative negligence and let you recover something even at 99 percent fault, though the practical value shrinks fast. A handful of states still follow contributory negligence, which blocks recovery if you bear even a sliver of blame. Which rule applies in your state shapes every negotiation that follows, so figure that out early.
Send the Demand Letter
Once your medical treatment has stabilized enough to understand the full scope of your damages, the formal claim begins with a demand letter sent to the at-fault party’s insurance company. This letter does the heavy lifting of framing the claim.
A strong demand letter lays out the facts of the incident, explains why the other party is at fault, describes your injuries and how they’ve affected your life, details your economic losses with supporting documentation, and states a specific dollar amount you’re willing to accept. The number should account for the full value of your damages, including medical costs, lost income, and pain and suffering, and should leave room for negotiation while remaining defensible.
A vague or poorly supported demand invites a lowball response. A detailed one, backed by organized evidence, signals that you’ve done your homework and are prepared to litigate if needed.
Negotiate, Then Mediate or Arbitrate
After receiving your demand, the insurance company runs its own investigation. Adjusters will review your medical records, may request an independent medical examination, and will look for any reason to dispute liability or minimize the value of your injuries. That is their job.
The first settlement offer is almost always lower than the claim is worth. Treat it as a starting point. Counter with evidence supporting your valuation and expect several rounds of back-and-forth. Accepting the first number is one of the most common mistakes claimants make.
If direct negotiation stalls, mediation is often next. A neutral mediator helps both sides find common ground without the cost and uncertainty of trial. Mediation is non-binding; you can walk away. Arbitration involves a neutral party who hears evidence and issues a decision that may be binding, depending on the agreement. Many insurance contracts include arbitration clauses, so check whether you’ve already agreed to this process before assuming you can go straight to court.
If Negotiation Fails, File Suit
When settlement talks and alternative dispute resolution don’t produce an acceptable result, filing a lawsuit moves the claim into the court system. Litigation adds a discovery phase where both sides exchange documents, take depositions, and build their case files. This can take months or years depending on the complexity of the case and the court’s schedule.
At trial, both sides present evidence to a judge or jury, who decides whether the defendant is liable and how much to award. A verdict is legally binding, though either side can appeal. Trials carry real risk: you might win more than the last settlement offer, or you might walk away with nothing. That uncertainty is the leverage that pushes most cases to settle before they get this far.
Most personal injury attorneys work on a contingency fee basis, taking a percentage of whatever you recover (commonly around a third for cases that settle before trial, and often more if the case goes to trial) and charging nothing upfront. Attorney fees and litigation costs are separate; ask any lawyer you’re considering to explain exactly how out-of-pocket expenses like filing fees, depositions, and expert witnesses are handled.
Before You Sign: Releases, Liens, and Taxes
Most injury claims end in a negotiated settlement. When both sides agree on a number, the deal is formalized in a written settlement agreement, and here is the part people often miss until it’s too late: that agreement almost always includes a release of all claims. Once you sign, you permanently give up the right to seek more compensation for anything connected to the same incident, including injuries that surface later. If the release includes an indemnity clause, you may even have to cover the other party’s costs if third-party claims arise. Settling before you understand the full extent of your injuries is dangerous. If your doctor says you might need surgery in two years, that future cost needs to be built into the settlement number before you sign.
You also won’t necessarily keep every dollar. If your health insurance paid for treatment related to the injury, it likely has a right to be reimbursed from your recovery through subrogation. Medicare, Medicaid, and private health plans all assert these rights, and ignoring them can create serious legal problems. Medical providers who treated you on a lien basis, agreeing to defer payment until the case resolves, have their own claims against the proceeds. Between attorney fees, litigation costs, and outstanding liens, the gap between the gross settlement figure and what actually reaches you can be substantial.
Taxes are the last piece. Compensation for physical injuries or physical sickness is generally not taxable as income under federal law, whether paid through a settlement or a verdict. Punitive damages are taxable regardless of the type of case. Compensation for purely emotional distress without an underlying physical injury is also taxable, except to the extent it reimburses you for medical care related to that emotional distress.3Office of the Law Revision Counsel. United States Code Title 26 – 104 Compensation for Injuries or Sickness Interest on a judgment and any portion of a settlement allocated to lost wages may also carry tax consequences. How the agreement characterizes each component of the payment matters, so the allocation language deserves careful attention before you sign.
Workplace Injuries Follow a Different Track
If you were hurt on the job, workers’ compensation is usually your only path to recovery against your employer. Workers’ comp covers medical expenses and a portion of lost wages without requiring you to prove the employer was at fault, but in exchange you generally cannot sue your employer for pain and suffering or other non-economic damages. If a third party other than your employer caused or contributed to the injury, such as a negligent driver who hit you while you were making a delivery or the manufacturer of defective equipment, you can pursue a separate personal injury claim against that third party while still collecting workers’ comp benefits. You may also have a claim outside workers’ comp if your employer’s conduct was intentional rather than merely negligent. These situations get complicated quickly, and the interaction between the two systems affects what you ultimately keep.
