How Personal Injury Law Works in Arizona

If you've been injured because of someone else's negligence in Arizona — whether in a car accident, a slip-and-fall, a medical procedure, or a workplace incident — personal injury law gives you the right to seek compensation. But understanding how the system works before you're in it can make a significant difference in the outcome of your case.

Arizona's Fault-Based System

Arizona uses a fault-based (also called "tort") system for personal injury claims. This means the person who caused your injury is financially responsible for your damages. To recover compensation, you need to prove that the other party owed you a duty of care (for example, drivers owe other road users a duty to drive safely), they breached that duty (they ran a red light, failed to maintain safe premises, or made a medical error), the breach caused your injury (there's a direct connection between their action and your harm), and you suffered actual damages (medical bills, lost wages, pain).

Pure Comparative Negligence

Under A.R.S. § 12-2505, Arizona follows "pure comparative negligence." This means you can recover damages even if you were mostly at fault — but your recovery is reduced by your percentage of responsibility. If you're found 30% at fault and your damages are $100,000, you recover $70,000. If you're 80% at fault, you still recover 20%. This is more generous than most states, which bar recovery entirely if you're over 50% at fault. Insurance companies will always try to assign you as much fault as possible to reduce their payout.

Types of Damages You Can Recover

Importantly, Arizona does not cap non-economic damages in personal injury cases. There's no artificial limit on what a jury can award for pain and suffering, unlike many other states. This is a significant advantage for seriously injured plaintiffs.

The Claims Process: What Actually Happens

Step 1: Medical Treatment

Your health comes first. See a doctor immediately after an injury — even if you feel fine. Some injuries don't show symptoms for days. Beyond the health imperative, early medical documentation creates the foundation of your legal case. Gaps in treatment give insurance companies ammunition to argue your injuries aren't serious.

Step 2: Investigation and Documentation

Your attorney (or you, if you're handling it yourself) gathers evidence: police reports, medical records, witness statements, photographs, and expert opinions. The stronger your documentation, the stronger your case.

Step 3: Demand and Negotiation

Once your treatment is complete (or your condition has stabilized), your attorney sends a demand letter to the at-fault party's insurance company. This outlines your injuries, your damages, and the amount you're seeking. The insurance company responds — usually with a lower offer — and negotiation begins. Most personal injury cases in Arizona settle at this stage without ever going to court.

Step 4: Lawsuit (if necessary)

If negotiation fails, your attorney files a lawsuit in Arizona Superior Court. Even after filing, many cases settle during the discovery phase or at mediation (which Arizona courts often require before trial). Only about 3–5% of personal injury cases actually go to trial.

Step 5: Trial or Settlement

If your case goes to trial, a jury determines liability and damages. Trials typically last 3–7 days for standard personal injury cases, longer for complex medical malpractice or product liability cases.

Common Types of Personal Injury Cases in Arizona

Car, truck, and motorcycle accidents are the most common — Arizona's wide highways and aggressive driving culture produce thousands of injury-causing accidents annually. Slip-and-fall and premises liability cases arise when property owners fail to maintain safe conditions. Medical malpractice cases involve healthcare providers who fall below the standard of care. Dog bite cases — Arizona has strict liability for dog owners (A.R.S. § 11-1025), meaning the owner is liable regardless of whether the dog has bitten before. Product liability cases involve defective or dangerous products. Wrongful death claims are filed by surviving family members when negligence causes a death.

How Personal Injury Attorneys Get Paid

The vast majority of Arizona personal injury attorneys work on contingency. You pay nothing upfront. The attorney advances all costs (filing fees, expert witnesses, medical record retrieval). If you win, the attorney takes a percentage — typically 33% if the case settles before trial, and 40% if it goes to trial. If you don't win, you owe nothing for attorney fees (though you may still owe some costs, depending on your agreement — always clarify this upfront).

Arizona's Statute of Limitations

You have two years from the date of injury to file a personal injury lawsuit in Arizona (A.R.S. § 12-542). For wrongful death, two years from the date of death. For medical malpractice, two years from the date of injury. If a government entity is involved (city bus, state vehicle, etc.), you must file a Notice of Claim within 180 days — far shorter than the standard deadline. Miss the deadline and you lose the right to sue, period. Don't wait.
