Arizona uses a legal doctrine called pure comparative fault to handle personal injury cases where more than one party may share responsibility for an accident. This rule is fundamental to understanding your rights — and it is one of the most frequently misunderstood aspects of Arizona personal injury law.

The Core Rule: You Can Recover Even If Partially at Fault

Under Arizona Revised Statutes § 12-2505, Arizona courts apportion fault among all parties involved in an accident. Each party's recovery is then reduced by their own percentage of fault. If you were 25% responsible for the accident and your damages total $100,000, you recover $75,000.

The word "pure" is critical here. Arizona's comparative fault system has no cutoff threshold. Even if you are 99% responsible, you can theoretically recover 1% of your damages. This is dramatically more favorable to injury victims than the "modified" comparative fault rules used in many other states, which bar any recovery once a plaintiff's fault exceeds 50% or 51%.

How Fault Percentages Are Determined

In most cases, fault percentages are negotiated between attorneys and insurance companies during settlement discussions. If negotiations fail and the case goes to trial, a jury determines the percentages after hearing evidence from both sides. Key evidence in fault disputes includes:

• Police accident reports and any traffic citations issued
• Eyewitness testimony
• Accident reconstruction expert analysis
• Traffic and surveillance camera footage
• Vehicle black box data (particularly useful in truck accidents)
• Cell phone records (to establish distracted driving)
• Road conditions, signage, and lighting at the time of the accident

Comparative Fault vs. Contributory Negligence

Some people confuse Arizona's comparative fault system with the older "contributory negligence" doctrine used in a few states, under which any fault on the plaintiff's part — even 1% — completely bars recovery. Arizona abolished contributory negligence in favor of comparative fault specifically to prevent this harsh result. Your right to partial recovery is protected regardless of your degree of fault.

The Insurance Company's Comparative Fault Strategy

Inflating the plaintiff's fault percentage is one of the most common and effective strategies insurance adjusters use to reduce claim values. If an adjuster can argue you were 30% at fault instead of 10%, they reduce their payout by 20 cents on every dollar — which on a $200,000 case is $40,000 in the insurer's favor.

Be extremely careful about what you say at the scene and in recorded statements. Phrases like "I didn't see them coming" or "I may have been going a bit fast" can be transformed into fault arguments. Describe what happened factually without making fault assessments.

Frequently Asked Questions

Can I recover if I was not wearing a seatbelt in Arizona?

Yes. Not wearing a seatbelt is a factor courts can consider in Arizona, though it is typically used to argue that some of your injuries were worsened by the absence of a seatbelt rather than to bar recovery entirely. The seatbelt defense applies to the extent your injuries would have been reduced had you been buckled — it does not eliminate the at-fault driver's liability for causing the accident.

What if multiple drivers were at fault including me?

Pure comparative fault handles multi-party accidents by assigning percentages to all at-fault parties, including potentially yourself. Each at-fault party bears responsibility proportional to their percentage. In Arizona, joint and several liability was significantly limited by tort reform, so each defendant is generally responsible only for their share of the fault.

How does comparative fault work in pedestrian and bicycle accident cases?

The same principles apply. If a pedestrian crosses against a signal and is struck by a speeding driver, fault might be apportioned between the two. The pedestrian's recovery is reduced by their own fault percentage, but they retain the right to recover for the portion attributable to the driver.

Does comparative fault apply to slip and fall and premises liability cases?

Yes — Arizona comparative fault applies to all personal injury cases. A property owner may argue the victim was not watching where they were going, was wearing improper footwear, or was in an area they should not have been. An attorney can counter these arguments with evidence of the property owner's knowledge of and failure to remediate the hazard.

Can the jury apportion fault to someone who was not a party to the lawsuit?

Yes, under Arizona law a jury can apportion fault to a non-party, including a party who cannot be sued (such as a government entity with specific protections or an employer in a workers' compensation situation). This is called "empty chair" defense and is used by defendants to spread fault to parties not present in the courtroom.
