Personal Injury Law in Arizona: A Practical Guide

Filing deadlines you cannot miss

A statute of limitations is the legal deadline for starting a lawsuit. Miss it and the court will almost always dismiss the case no matter how strong the evidence, so the deadline is usually the first thing worth pinning down. Arizona's general personal-injury limit is two years from the date of injury, set by A.R.S. § 12-542, and it governs most claims — car, motorcycle, and truck collisions, slip-and-fall and other premises cases, product defects, assault and battery, and ordinary negligence claims involving animals.

The same two-year window applies to property damage and to wrongful death, but the clock can start on a different day depending on the claim. For wrongful death the two years run from the date of death, not the date of the original injury — so a person hurt in January who dies in June gives survivors until that June two years later, not the following January. Medical malpractice follows the two-year rule but adds a discovery component: the clock generally starts when the patient discovers, or reasonably should have discovered, both the injury and its link to negligent care, which matters in cases like a surgical item left in the body that surfaces years later.

When the clock pauses

Arizona pauses, or "tolls," the limitations period in a few situations. For a child, the deadline does not begin to run until the child turns 18, after which the normal period applies — so a ten-year-old hurt today would generally have until age 20 to sue. The period is likewise tolled while a person is legally incapacitated at the time the claim arises. These exceptions are narrower than they look and do not extend the separate government-claim and dog-bite deadlines in the same way, so they are worth confirming rather than assuming.

How fault affects what you recover

Arizona uses pure comparative negligence under A.R.S. § 12-2505. A jury assigns each party a percentage of fault, and the injured person's award is reduced by their own share. The defining feature of the "pure" version is that there is no cut-off: a plaintiff can recover something even if found 99 percent at fault. That is more generous than the "modified" systems used in many states, where a plaintiff who is 50 or 51 percent or more at fault recovers nothing at all.

The math is straightforward. If a jury values the total harm at $100,000 and finds the injured driver 30 percent responsible for a crash, the recovery is $70,000. A grocery-store fall valued at $50,000 with the customer 40 percent at fault yields $30,000. Even a pedestrian found 75 percent at fault for an unsafe crossing can collect 25 percent of the award — a result that would be zero in a modified-comparative state. Because every percentage point of fault has a direct dollar cost, insurers routinely argue the injured person was more careless than the facts support: that a seat belt went unworn, that attention lapsed, that a pre-existing condition explains the symptoms, or that treatment was delayed. Contemporaneous evidence — photographs, video, witness accounts, and the police report — is what keeps an assigned fault percentage honest.

Multiple defendants pay only their own share

A point that surprises many people: Arizona abolished joint and several liability in 1987. Under A.R.S. § 12-2506, when more than one defendant is at fault, each is liable only for its own proportionate share of the damages — for both economic losses like medical bills and non-economic losses like pain and suffering. If one defendant is 60 percent at fault and another 40 percent on a $200,000 verdict, the first owes $120,000 and the second $80,000; neither can be forced to cover the other's portion. Narrow exceptions restore shared responsibility — chiefly where defendants acted in concert, where one acted as another's agent, or where a federal duty applies — but the default rule is several liability only. This makes identifying every responsible party, and their insurance, important early on.

What you can recover

Damages in Arizona fall into two broad groups. Economic damages are the measurable, receipt-backed losses; non-economic damages compensate for harms that have real value but no invoice.

Economic damages

These cover past and future medical care — emergency treatment, hospital stays, surgery, therapy, medication, equipment, and home health — along with lost income, diminished future earning capacity, lost benefits, property repair or replacement, and the cost of services the injured person can no longer perform, such as childcare or home maintenance. Future losses usually require expert support: physicians for the cost of ongoing care, and vocational or economic experts for lost earning capacity. Proof of income loss typically draws on pay records, tax returns, and employer statements.

Non-economic damages

These compensate for physical pain, emotional distress, loss of enjoyment of life, disfigurement and scarring, permanent impairment, and a spouse's loss of consortium — the companionship, affection, and services lost when a partner is seriously hurt. There is no formula. Lawyers and juries sometimes reason from a multiple of the economic damages or from a daily amount assigned over the recovery period, but ultimately a jury decides what is fair, which is why these awards vary widely from case to case.

Punitive damages

Punitive damages are different in kind: they punish and deter rather than compensate, and Arizona reserves them for aggravated conduct — an "evil mind," meaning intent to harm, or conscious disregard of a substantial risk of significant harm. The plaintiff must prove that state of mind by clear and convincing evidence, a standard the Arizona Supreme Court set in Rawlings v. Apodaca, 151 Ariz. 149 (1986); ordinary carelessness is not enough. Arizona does not impose a statutory dollar cap on punitive damages. Instead they are constrained by federal and state due-process limits on how far a punitive award may exceed the compensatory award; the U.S. Supreme Court has signaled that ratios beyond single digits are constitutionally suspect, and Arizona courts have applied even tighter scrutiny. (A.R.S. § 12-689 is sometimes miscited as a cap; it actually exempts certain regulated manufacturers and sellers from punitive liability when they complied with applicable government approvals — a shield, not a ceiling.)

Damages at a glance

The table below summarizes how each category is treated, along with the key exceptions that limit recovery in specific contexts — claims against the government, on-the-job injuries, and product defects that cause only financial loss.

Why Arizona has so few damage caps

Most states limit non-economic or medical-malpractice damages by statute. Arizona cannot. Article II, Section 31 of the Arizona Constitution states that no law shall be enacted limiting the amount of damages recoverable for causing the death or injury of any person. The Arizona Supreme Court has enforced that provision to strike down legislative attempts at caps, which puts Arizona among the small group of states where damage caps are unconstitutional.

The practical effects are significant. There is no cap on pain-and-suffering damages in ordinary injury cases. There is no cap on medical-malpractice damages, economic or non-economic — a meaningful difference from states with fixed malpractice limits. And there is no cap on wrongful-death damages, which can include funeral and burial costs, pre-death medical expenses, lost financial support, and the survivors' loss of companionship and grief. The notable exceptions to Arizona's no-cap landscape are not really caps at all but limits of a different sort: the due-process ceiling on punitive damages described above, and the procedural barriers that apply to claims against the government.

Claims against government entities

Suing a city, county, school district, state agency, or government employee follows a separate and far less forgiving track. Arizona has waived sovereign immunity in many situations under its governmental-liability statutes (A.R.S. § 12-820 and following), but only for claimants who follow the procedure exactly.

The 180-day notice of claim

Before any lawsuit, A.R.S. § 12-821.01 requires a written Notice of Claim filed within 180 days of when the claim accrues. This is not the lawsuit itself — it is formal advance notice — but missing the 180-day window permanently bars the claim even though the ordinary two-year statute of limitations has not run. The notice must identify the claimant, describe the facts giving rise to the claim, state where the incident happened, and demand a specific settlement amount supported by facts. Where it goes depends on the defendant: the Attorney General or the relevant agency for state claims, the Clerk of the Board of Supervisors for counties, the city or town clerk for municipalities, and the superintendent or clerk for school districts.

After the notice is served, the entity has 60 days to respond. It can pay, deny, or do nothing — and silence past 60 days counts as a denial. A lawsuit cannot be filed until the claim is denied or the 60 days pass, and once that happens the suit still has to be brought within the general two-year limit measured from when the claim accrued. A typical sequence: an injury in March, a notice filed by late August (within 180 days), a city response or deemed denial by late October, and the lawsuit filed before the two-year deadline the following March.

One myth worth dispelling: because the Arizona Constitution bars damage caps for injury and death, the state does not impose a fixed dollar ceiling on what a government entity can be made to pay. The real constraints on government claims are procedural — the notice requirement and the immunities preserved by statute for certain discretionary functions — not a damages cap. One substantive limit does apply, though: punitive damages are never available against a public entity or an employee acting within the scope of employment (A.R.S. § 12-820.04), even though compensatory damages are. Common theories include dangerous conditions on public property, negligent operation of government vehicles, negligence by employees acting within the scope of their work, and failure to maintain roads, sidewalks, and public facilities.

Common case types in Arizona

Arizona's geography, climate, and demographics shape the injury cases that arise here. Motor-vehicle collisions are the most common, driven by heavy traffic around Phoenix and Tucson and long interstate corridors. Arizona is an at-fault (not no-fault) state, so an injured driver can pursue the responsible driver directly. A persistent problem is thin coverage: a meaningful share of Arizona drivers are uninsured or underinsured, which makes a person's own uninsured/underinsured motorist coverage one of the most important protections they can carry.

Premises-liability and slip-and-fall claims are frequent, and the climate adds hazards other states rarely see — backyard and hotel pools are everywhere, and summer surface temperatures turn playground equipment, metal fixtures, and parking-lot pavement into genuine burn risks. Medical malpractice is litigated against the state's large hospital systems and covers surgical mistakes, misdiagnosis and delayed diagnosis, birth injuries, medication and anesthesia errors, and emergency-room negligence; Arizona's absence of malpractice caps makes these cases more viable here than in capped states.

Most workplace injuries run through workers' compensation rather than a personal-injury suit, but a separate claim may exist when a third party (not the employer) caused the harm, when the employer carried no required coverage, or for certain independent contractors. Product-liability claims proceed under strict liability, meaning the plaintiff need not prove negligence — only that a defect caused the injury. The state also sees significant numbers of pedestrian and bicycle cases (Phoenix consistently ranks among the most dangerous metros for pedestrians) and, given a large senior population, nursing-home neglect and abuse claims involving falls, pressure ulcers, medication errors, malnutrition, and mistreatment.

Distinctive Arizona rules worth knowing

Dog bites: strict liability, but watch the one-year clock

Arizona has one of the country's strongest dog-bite laws. Under A.R.S. § 11-1025, an owner is strictly liable when their dog bites someone who is in a public place or lawfully on private property — regardless of whether the dog had ever bitten before, whether the owner knew it was dangerous, or whether the owner was careful. There is no "one free bite." The defenses are narrow: trespassing, provocation, and injuries by police or military dogs at work. A key trap is timing — the statutory strict-liability claim must be filed within one year, not the usual two. A negligence claim over the same bite carries the two-year deadline, and injuries that do not involve a bite (a dog knocking someone down) must be proven as negligence rather than strict liability.

Serving alcohol: limited liability

Arizona's dram-shop law (A.R.S. § 4-311) lets an injured person sue a licensed seller — a bar, restaurant, or liquor store — but only where the establishment served someone who was "obviously intoxicated" and that sale proximately caused the injury. "Obviously intoxicated" is a high bar requiring visible, severe impairment, which many drunk drivers do not display well enough to trigger liability. Social-host liability is narrower still: under A.R.S. § 4-301, a private host is generally liable only for serving alcohol to someone under 21 whom they knew or should have known was underage, and not for serving adults who later cause harm.

Auto insurance minimums

Arizona requires minimum liability coverage of $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage. These floors are often inadequate for a serious injury, which is again why uninsured/underinsured motorist coverage matters so much.

The collateral-source rule and the seat-belt defense

Arizona generally follows the collateral-source rule: payments from the injured person's own health or disability insurance do not reduce what the defendant owes, and a defendant cannot argue that compensation is undeserved because insurance already paid the bills. (Subrogation rules may still require reimbursing an insurer out of a settlement, so the net recovery can be affected.) On the other hand, Arizona allows a seat-belt defense — evidence that an injured person was unbelted can be presented as comparative negligence, supporting an argument that some of the injuries were avoidable and the award should be reduced accordingly.

Who may bring a wrongful-death claim

Under A.R.S. § 12-612, wrongful-death claims are brought in a priority order: first a surviving spouse; then the children if there is no spouse (or the spouse does not act within the statutory window); then parents; and otherwise the estate's personal representative on behalf of those survivors. Recoverable damages include both economic losses such as funeral costs and lost financial support and non-economic losses such as the survivors' grief and loss of companionship.
