If you were partially at fault for an accident in Arizona, you can still recover compensation. That’s because Arizona follows a system called pure comparative fault — one of the most victim-friendly standards in the country. Under this rule, your compensation is reduced by your percentage of responsibility. Even if you were 90% at fault, you can still recover 10% of your damages. Understanding how comparative fault works is essential if you’ve been injured and the other side is trying to shift blame onto you.
Insurance adjusters know this rule well, and they use it strategically. The more fault they can assign to you, the less they pay. That’s why having an experienced personal injury attorney matters — someone who can push back on inflated fault percentages and protect the full value of your claim.
This guide explains exactly how Arizona’s comparative fault system works, how fault is determined, what it means for your settlement, and what you can do to keep your share of the blame as low as possible.
Arizona’s comparative fault law is codified in Arizona Revised Statutes § 12-2505. It establishes that multiple parties can share responsibility for an accident, and each party’s compensation is adjusted based on their percentage of fault. Arizona uses the “pure” version of this rule, which is more generous to injured victims than the “modified” comparative fault systems used in many other states.
In states with modified comparative fault, you lose your right to compensation once your fault reaches a certain threshold — typically 50% or 51%. In Arizona, there is no such threshold. You can be 99% at fault and still recover 1% of your damages. While that’s an extreme example, it illustrates why Arizona’s pure system is meaningfully different from what many people expect.
You’re involved in a car accident. A jury finds you 30% at fault for following too closely and the other driver 70% at fault for running a red light. Your total damages are $100,000. Under Arizona’s comparative fault rule, your compensation is reduced by 30% — so you recover $70,000.
That 30% figure isn’t just a legal formality. It can mean tens of thousands of dollars. How fault is assigned — and by whom — is one of the most important variables in any personal injury case.
Fault in a personal injury case isn’t assigned by a single authority. It’s determined through negotiation, evidence, and in some cases a jury verdict. The process involves multiple sources of information, each carrying different weight.
In most cases, the insurance adjusters for both parties independently assess fault and negotiate a shared percentage. If negotiations fail, the case goes to litigation, and a judge or jury makes the final determination. The stakes of that determination are high — a 10-percentage-point shift in fault can change the outcome of a claim by thousands of dollars.
Once the court or insurer assigns a fault percentage, it directly reduces your recovery. Comparative fault applies to both economic and non-economic damages, which means it proportionally reduces your medical bills, lost wages, pain and suffering, and all other damages.
If your total economic damages — medical bills, lost wages, property damage — are $80,000 and you’re found 25% at fault, you recover $60,000. The remaining $20,000 represents the portion attributable to your own negligence. This applies regardless of how your medical treatment was structured or how severe the injuries are.
The same reduction applies to non-economic damages like pain and suffering. If your pain and suffering is valued at $120,000 and you’re 25% at fault, you receive $90,000. These damages are often the largest component of a claim, which makes the fault percentage especially significant here.
According to the Arizona Department of Transportation (ADOT), Arizona sees tens of thousands of vehicle crashes involving injuries every year. IIn the majority of those cases, the parties share fault to some degree, which makes comparative fault one of the most practically relevant laws for anyone injured on Arizona roads.

Insurance adjusters are trained to use comparative fault as a cost-reduction tool. Their job is to find any basis — however small — to assign you a portion of the fault. Every percentage point they assign to you reduces what they have to pay.
An experienced personal injury attorney counters each of these tactics with evidence, legal arguments, and — if needed — expert testimony. Big Chad Law has handled hundreds of comparative fault disputes across Arizona, earning over 600 five-star reviews from clients who trusted us when the other side tried to shift the blame.
Your behavior before and after an accident has a direct impact on how comparative fault is assigned. The steps you take — and avoid — in the hours and days after an accident can meaningfully change the outcome of your claim.
Keep in mind that you have two years from the date of the accident to file a personal injury lawsuit in Arizona, under Arizona Revised Statutes § 12-542. Missing this deadline forfeits your right to compensation entirely.
Yes. Arizona uses pure comparative fault under A.R.S. § 12-2505, which allows you to recover compensation regardless of your fault percentage. Your award is simply reduced by your share of responsibility. Even if you were 60% or 70% at fault, you can still recover the remaining portion. There is no fault threshold that bars recovery, unlike many other states.
Most states use modified comparative fault, which bars recovery once the plaintiff’s fault reaches 50% or 51%. Arizona’s pure comparative fault system has no such cutoff. You can be 99% at fault and still recover 1% of your damages. This makes Arizona’s system significantly more protective of injured victims than the majority of other U.S. states.
In most cases, the insurance adjusters for each party negotiate fault. If they can’t agree, the case moves to litigation and a judge or jury makes the final determination. Evidence such as police reports, witness statements, expert testimony, dashcam footage, and physical damage patterns all factor into that determination.
Arizona’s comparative fault system handles multi-party accidents by distributing fault percentages among all responsible parties. The court assigns each party — including you, if applicable — a percentage of the total fault and reduces your recovery by your percentage. You can pursue compensation from each at-fault party based on their share of responsibility.
Yes, often significantly.Insurance companies assign fault through their own investigation, which they design to minimize payouts. An attorney can challenge that assessment with additional evidence, expert witnesses, accident reconstruction, and legal arguments. Reducing your fault percentage by even 10 to 20 points can increase your recovery by tens of thousands of dollars.
They’re assigning you fault. We’re here to push back.
