Yes, Arizona is a pure comparative negligence state. Under A.R.S. § 12-2505, you can recover damages in a personal injury case even if you were mostly at fault for what happened; your award is simply reduced by whatever percentage of fault a jury assigns to you. There is no cutoff point at which your claim disappears, which puts Arizona among the more claimant-friendly states in the country.
How the Rule Works in Practice
The math is straightforward. A jury first calculates your total damages, then reduces that number in direct proportion to your share of fault. Suppose the jury values your losses at $100,000. If you were 30 percent at fault, you take home $70,000. If you were 80 percent at fault, you still take home $20,000.
Contributory negligence and assumption of risk are both treated as questions of fact for the jury under A.R.S. § 12-2505. Neither works as an automatic legal defense that ends your case. The jury folds your conduct into the overall fault picture and adjusts your recovery from there.
Why “Pure” Matters
Most states use some form of modified comparative negligence. In those states, once your share of fault crosses a threshold, usually 50 or 51 percent, your claim is worth zero regardless of how serious your injuries are. A few states still follow the older contributory negligence rule, where any fault at all on the injured person’s part, even 1 percent, wipes out recovery entirely.
Arizona’s pure system has no such cutoff. A driver who is 95 percent responsible for a collision can still collect 5 percent of their proven damages. The distinction matters most in cases where fault is genuinely shared and the injured person’s own conduct played a large role. Those claims would vanish in a modified state. In Arizona, they survive, though the payouts shrink accordingly.
The One Situation Where the Rule Doesn’t Apply
A.R.S. § 12-2505 carves out a single hard exception. If you intentionally, willfully, or wantonly caused or contributed to your own injury, the proportional-reduction framework no longer protects you. Cross the line from carelessness into deliberate or reckless self-harm and you lose the right to recover under the statute. Ordinary negligence on your part, no matter how significant, keeps you inside the comparative negligence system.
Assumption of Risk Is Not a Separate Bar
Arizona does not treat assumption of risk as a claim-killing defense. The statute groups it with contributory negligence and sends both to the jury as fault questions. If a jury finds you voluntarily took on a known risk, your damages drop by whatever percentage that conduct represents, but your case is not dismissed on that basis alone.
This regularly comes up in recreational injury cases, sporting events, and activities where participants sign waivers. A defendant will argue you knew the risks and accepted them. That argument becomes part of the overall fault allocation instead of a legal bar that ends the case before the jury weighs in.
Fault When More Than One Person Is to Blame
Being able to recover under pure comparative negligence is not the same as being able to collect. Arizona’s fault allocation pairs with A.R.S. § 12-2506, which abolishes joint and several liability for most personal injury, property damage, and wrongful death cases. Liability is several only. Each defendant pays only the share of damages that matches their own percentage of fault.
Say a jury awards you $200,000 and finds Defendant A was 60 percent at fault and Defendant B was 40 percent at fault. Defendant A owes you $120,000. Defendant B owes you $80,000. If Defendant B is broke or uninsured, you cannot force Defendant A to make up the difference. You absorb the shortfall.
Fault Assigned to People Who Aren’t in the Lawsuit
Under A.R.S. § 12-2506(B), the jury considers the fault of every person who contributed to the injury, whether or not they were sued. A defendant can file a pre-trial notice identifying a non-party who shares blame, and the jury can then assign that absent person a percentage of fault.
Every point assigned to a non-party comes out of the total pool. If the jury decides a non-party was 25 percent at fault, the named defendants collectively owe 25 percent less, and you cannot collect that 25 percent from anyone unless you separately sue the non-party. Fault assessments against non-parties do not create liability for them in the current case and cannot be used as evidence of liability in any other action.
Defense attorneys use this mechanism aggressively. In a car accident case, they might point to a road maintenance contractor, a vehicle manufacturer, or another driver who left the scene. Each percentage shifted to a non-party directly reduces what you actually recover.
How Comparative Negligence Shapes Insurance Settlements
Most Arizona personal injury cases settle through insurance negotiations, not trials. Adjusters build fault percentages into their offers from the start. Even a modest assignment of 10 or 15 percent translates into thousands of dollars off a six-figure claim.
Adjusters look for anything suggesting you contributed to the accident: statements you made at the scene, your speed, whether you were distracted, whether you were wearing a seatbelt. A casual remark like “I didn’t see them coming” can become the basis for a fault argument that meaningfully reduces your payout. Those settlement percentages are not binding the way a jury verdict is, but they anchor the negotiation and are hard to move without strong evidence.
Because liability is several, each defendant’s insurer only weighs that defendant’s slice of fault. If several insurers are involved, you negotiate with each one separately based on their insured’s share.
The Filing Deadline Still Applies
None of this matters if you miss the deadline. A.R.S. § 12-542 gives you two years from the date of injury to file a personal injury lawsuit. Two years sounds generous, but disputed fault cases take time to build. Gathering medical records, accident reports, and expert opinions to keep your assigned fault percentage low is not something to start in the last few months. The earlier you begin, the more room you have to protect your share of any recovery.
