Partially at Fault in Arizona? You May Still Recover

Yes. Arizona’s pure comparative fault law allows an injured person to recover compensation even when they share responsibility for what happened. Your recovery is reduced by your percentage of fault, but it is never eliminated entirely unless you were completely responsible for the injury. This is one of the most plaintiff-friendly standards in the country, and it is why the fault percentage assigned to you becomes the most contested issue in almost every personal injury claim in Arizona.

Arizona’s Pure Comparative Fault Rule

Arizona codified its approach to shared fault in Arizona Revised Statutes Section 12-2505. The statute adopts the doctrine of pure comparative fault, also called pure comparative negligence. Under this framework, courts and juries assign a percentage of fault to each party involved in an incident. That percentage then reduces the injured person’s recovery proportionally.

The pure comparative fault system stands in sharp contrast to the modified comparative negligence rules used in many other states. In those states, a plaintiff found 50 or 51 percent at fault is completely barred from any recovery. Arizona imposes no such cutoff. A person found 90 percent at fault for their own injury can still recover 10 percent of their total damages from the defendant who contributed the remaining 10 percent. The only point at which recovery is eliminated is when a party is found 100 percent responsible.

To illustrate how this works in practice: a driver involved in a Phoenix intersection collision is awarded $200,000 in total damages, but the jury determines that driver was 35 percent at fault for the crash. Under Arizona law, that driver recovers $130,000, which is 65 percent of the total. The 35 percent attributed to their own conduct is subtracted from the award, not used to eliminate it.

How Fault Is Determined in an Arizona Personal Injury Case

Fault is not determined by a single document or a single statement. It emerges from the totality of evidence assembled during investigation and, if necessary, litigation. In Arizona personal injury cases, the process of assigning fault typically draws on several categories of evidence.

  • Physical evidence: Accident scene photographs, vehicle damage patterns, skid marks, road conditions, and traffic control device positioning.
  • Law enforcement reports: Police reports from the responding agency that document observations, citations issued, and preliminary fault assessments.
  • Witness statements: Accounts from bystanders, other drivers, passengers, and anyone with direct observation of the events leading to the injury.
  • Electronic data: Dashcam footage, surveillance video, vehicle event data recorders, and cell phone records that establish what each party was doing at the moment of impact.
  • Expert reconstruction: In complex cases, accident reconstruction specialists analyze the physical evidence to produce a scientifically supported account of how the crash occurred and what factors contributed to it.

The Legal Information Institute at Cornell Law School describes comparative fault as a legal principle that distributes responsibility for harm in proportion to each party’s contribution to the harmful event. In Arizona, that proportional distribution is carried out at trial by the jury, or through settlement negotiations that attempt to anticipate what a jury would decide.

Multiple Defendants and Non-Party Fault in Arizona

Arizona’s comparative fault framework extends beyond the immediate parties to a lawsuit. Under Arizona Revised Statutes Section 12-2506, each defendant in a personal injury case is liable only for their own proportionate share of fault. The old doctrine of joint and several liability, which allowed a plaintiff to recover the full amount of damages from any single defendant regardless of that defendant’s individual percentage of fault, was abolished in Arizona.

This matters because it affects how a plaintiff collects. If a defendant is found 25 percent at fault and the total damages are $400,000, that defendant owes $100,000. If that defendant is insolvent or uninsured, the plaintiff cannot recover the uncollected $100,000 from the other defendants. Each defendant pays only their share.

Arizona law also permits fault to be allocated to parties who are not named defendants in the lawsuit, including individuals or entities who settled before trial or who are not subject to the court’s jurisdiction. Fault assigned to these non-parties reduces the total recoverable from the named defendants. This provision is frequently used by defense attorneys to shift blame toward absent third parties, which is one of the reasons why thorough pre-litigation investigation is so important.

Why the Fault Percentage Is the Real Fight

Insurance companies in Arizona know the comparative fault system well. Their adjusters and defense attorneys are trained to find any evidence that can increase the injured person’s assigned fault percentage. A recorded statement made in the first hours after an accident, posts on social media that suggest physical activity, gaps in medical treatment, or prior injuries affecting the same body part are all used to argue that the injured person bears more responsibility. Every percentage point shifted to the plaintiff reduces the insurer’s payout.

Exceptions: When Comparative Fault Does Not Protect the Defendant

Arizona’s comparative fault framework does not apply universally. Certain categories of defendant conduct take the case outside the proportional liability system entirely.

  • Intentional misconduct: Under A.R.S. Section 12-2505, a defendant who intentionally caused the injury cannot invoke comparative fault to reduce their liability. The statute specifically provides that comparative fault does not apply in cases of willful or wanton conduct.
  • Felonious acts: A defendant whose conduct constitutes a felony cannot shift blame to the injured plaintiff through a comparative fault argument in most circumstances.
  • Strict liability contexts: Some Arizona statutes impose liability regardless of comparative fault analysis. Arizona’s dog bite statute under A.R.S. Section 11-1025, for example, holds dog owners strictly liable for bites regardless of the victim’s conduct, subject to provocation exceptions.

The Two-Year Filing Deadline

Arizona imposes a two-year statute of limitations on personal injury claims under Arizona Revised Statutes Section 12-542. The deadline begins on the date of the injury. For car accident claims, that is the date of the crash. For premises liability claims, it is the date of the fall or the incident causing harm. Missing this deadline almost always results in permanent loss of the right to sue, regardless of how strong the underlying case is or how clear the defendant’s fault may be.

Claims against government entities in Arizona require a notice of claim to be served within 180 days of the incident under A.R.S. Section 12-821.01. This shorter deadline often catches people off guard. If a crash involved a city vehicle, a poorly maintained government road, or a municipal employee acting in the scope of their duties, the notice of claim requirement applies and must be satisfied before any lawsuit can proceed.
