One of the most common questions after an Arizona crash is some version of: "I might have been partly at fault — does that mean I get nothing?" Under Arizona law, the answer is no, and the rule behind that answer is one of the biggest factors in how claim value works here.
Arizona is a pure comparative fault state
Under A.R.S. § 12-2505, Arizona follows pure comparative fault. When more than one person contributed to causing a crash, responsibility is divided in percentages — and an injured person's compensation is reduced in proportion to their own share of fault, rather than eliminated.
Two things make Arizona's version notable:
- No cutoff. Some states bar recovery entirely once a person's fault passes 50%. Arizona has no such threshold — a person found mostly at fault can still recover the portion attributable to others.
- Proportional reduction. The reduction matches the fault percentage. A person assessed 20% of the fault would see compensation reduced by that 20% share.
What this means for claim value
Comparative fault means an Arizona claim's value has two moving parts, not one:
- The damages themselves — medical expenses, lost income, and the other recognized categories of harm, which set the starting figure.
- The fault allocation — the percentage applied against that figure.
Because both parts matter, fault questions can affect value as much as damages questions do. Evidence that bears on how the crash happened — reports, photographs, witness accounts, vehicle positions — can carry real weight, since a shift of even a modest percentage changes the outcome proportionally.
It's also worth knowing that fault percentages are not fixed facts sitting in a file somewhere. They are conclusions people reach from the evidence — and in a disputed claim, how fault is divided may itself be one of the contested questions.
A caution about simple math
The proportional idea is simple, but real claims rarely are. Damages categories can be disputed, fault can be disputed, and more than two people or entities can share responsibility in a single crash. That's why percentage examples explain the rule without predicting any particular result — no formula substitutes for the specific facts, evidence, and coverage involved in an actual claim.
The practical takeaway: in Arizona, being partly at fault changes the math but does not close the door. Understanding that the reduction is proportional — and that the percentage itself often turns on evidence — is a useful starting point for thinking about what any claim may be worth.
