Arizona’s Pure Comparative Negligence Law Explained

The first thing an insurance adjuster looks for after a serious crash is a reason to blame you. Not because you caused it, but because in Arizona every percentage point of fault assigned to you comes directly out of your settlement. People hear they might be partly responsible and assume the claim is finished. In Arizona, it almost never is.

What Pure Comparative Negligence Means

Arizona follows the pure form of comparative negligence, which is the most claimant friendly version in use anywhere in the country. Under A.R.S. § 12-2505, if a jury applies contributory negligence or assumption of risk, your action is not barred. Your full damages are simply reduced in proportion to your share of the fault.

Most states do not work this way. Roughly two thirds use a modified system that cuts off recovery entirely once an injured person crosses 50 or 51 percent. A handful still follow old contributory negligence rules where 1 percent of blame defeats the whole claim. Arizona has no cutoff at all. Someone found 90 percent responsible still recovers 10 percent of their damages.

The statute also makes fault a question of fact reserved for the jury. An adjuster telling you that you were half at fault is stating a settlement position, not a legal conclusion.

How the Math Works

Say a jury values a case at $200,000 and finds the injured driver 25 percent responsible for pulling into an intersection without a clear view. The award becomes $150,000. Move that figure to 40 percent and the award becomes $120,000.

That arithmetic explains almost everything about how these claims get negotiated. Each 10 percent an adjuster can attach to you is worth $20,000 on a case that size, which is why so much energy goes into establishing who actually caused the collision and into building the value of damages that percentage gets applied against.

The One Exception Written Into the Statute

Section 12-2505 contains a single carve out. There is no right to comparative negligence in favor of a claimant who intentionally, wilfully, or wantonly caused or contributed to the injury or death. Ordinary carelessness, even substantial carelessness, keeps you inside the pure comparative system. Deliberate or reckless conduct can take you outside it.

Arizona Abolished Joint and Several Liability

This is the part most guides skip, and it changes how multi defendant cases have to be built.

Under A.R.S. § 12-2506, the liability of each defendant is several only and not joint. Each defendant pays only the amount matching its own percentage of fault, and the court enters a separate judgment for that amount. If a trucking company is 70 percent responsible and a road contractor is 30 percent, you cannot collect the contractor’s share from the trucking company. If the contractor is uninsured or insolvent, that 30 percent may simply be gone.

The statute preserves joint liability in three narrow situations. Parties acting in concert on an intentional tort, a person acting as the agent or servant of another party, and liability arising under the Federal Employers’ Liability Act. Everything else is apportioned and separate.

The Nonparty at Fault Rule

Section 12-2506 also lets a defendant point at someone who is not in the courtroom. If the defending party gives notice before trial under the applicable court rule, the jury may assign fault to a nonparty who contributed to the injury. That assessment never makes the nonparty liable and cannot be used as evidence against them in any other case. It exists only to size the named defendants’ shares accurately.

In practice it means the defense has a tool for shrinking its own exposure by pointing at an empty chair, whether that is a phantom driver, a vehicle manufacturer, a property owner, or an employer. Deadlines for these designations are short, and responding to one requires investigation that should have started immediately after the crash. That is one of several reasons preserving evidence early matters more in Arizona than in states with joint liability.

How Insurers Use Comparative Fault Against You

  • Speed and positioning arguments in Yuma car accidents, suggesting you could have avoided the collision with better reactions.
  • Helmet, visibility, and lane position arguments in motorcycle crash claims, most of which have no legal bearing on fault for the collision itself.
  • Crosswalk and attention arguments in pedestrian accident claims.
  • Open and obvious hazard arguments in slip and fall claims, asserting you should have seen the danger and walked around it.
  • The recorded statement is where most of this material gets manufactured, which is why talking to adjusters before you understand your own injuries so often ends badly.

Pushing Back on a Fault Percentage

Fault allocation is an argument, and arguments respond to evidence. Crash reconstruction, physical evidence from the scene, black box and telematics data, surveillance footage, cell phone records, and the citation history of the other driver all move the number. So does a clear account of what negligence requires, since an adjuster’s theory of your fault frequently collapses once someone asks which duty you supposedly breached.
