# Arizona Personal-Injury Practice

> **NOT LEGAL ADVICE.** Arizona tort practice is deadline-sensitive
> and has structural features that diverge sharply from most states —
> pure comparative negligence, the constitutional ban on damage caps,
> the nonparty-at-fault apportionment regime, and the strict public-
> entity notice of claim. Statute numbers, day counts, and SOLs
> change — verify every SOL, threshold, and predicate-notice clock
> against the current A.R.S. before relying, and consult a licensed
> Arizona attorney about your specific case.

Use this subject-matter bundle for Arizona personal-injury and tort
actions — auto accidents, premises (slip-and-fall), product and
general negligence, medical malpractice, wrongful death, dog bites,
and claims against governmental entities.

## At a glance — the things that move every AZ case

1. **2-year personal-injury SOL** at A.R.S. § 12-542. Claims against
   a **public entity / public employee** run on a much shorter
   **1-year SOL** (A.R.S. § 12-821) and require a **180-day notice
   of claim** first (A.R.S. § 12-821.01). Calendar at intake.
2. **PURE comparative negligence** under A.R.S. § 12-2505 — a
   plaintiff's recovery is **reduced** in proportion to fault but is
   **NEVER barred**, even if the plaintiff is **more at fault than
   the defendant**. Arizona is NOT a modified / 50%-bar state.
3. **Several liability only** under A.R.S. § 12-2506 — Arizona
   **abolished joint liability**. Each defendant pays only its own
   allocated percentage of fault. Identify every at-fault actor.
4. **Nonparty at fault** (A.R.S. § 12-2506(B)) — the defense may
   shift fault to an absent person by serving a **notice of nonparty
   at fault** within the deadline in Ariz. R. Civ. P. 26(b). This
   is the central defensive lever in Arizona tort cases.
5. **NO DAMAGE CAPS — constitutional.** The Arizona Constitution
   **prohibits** the legislature from limiting injury/death damages
   (**art. 2 § 31** and **art. 18 § 6**). Arizona has **no med-mal
   cap and no non-economic-damages cap** of any kind.
6. **Med-mal preliminary expert affidavit** (A.R.S. § 12-2603) plus
   **expert qualification** (A.R.S. § 12-2604) — the early
   gates in health-care negligence cases (the § 12-2603 certification
   is filed **with the claim**, not pre-suit; the affidavit is served
   with the Rule 26.1 initial disclosures).
7. **Dog-bite strict liability** (A.R.S. § 11-1025) — owner liable
   regardless of the dog's prior viciousness or the owner's knowledge.
8. **UM/UIM coverage** is a frequent secondary recovery source in
   auto cases — confirm the policy and any statutory selection.

## Statute-of-limitations catalog

| Claim | SOL | Citation |
|---|---|---|
| **Personal injury (general negligence)** | **2 years** | A.R.S. § 12-542 |
| **Wrongful death** | **2 years** | A.R.S. § 12-542 |
| **Auto bodily injury / property damage** | **2 years** | A.R.S. § 12-542 |
| **Premises / slip-and-fall** | **2 years** | A.R.S. § 12-542 |
| **Medical malpractice** | **2 years** | A.R.S. § 12-542 |
| **Dog bite (statutory strict liability)** | **1 year** | A.R.S. § 12-541(5) — "liability created by statute" (the § 11-1025 strict-liability action) |
| **Dog bite (common-law negligence)** | **2 years** | A.R.S. § 12-542 |
| **Claim against a public entity / employee** | **1 year** + **180-day notice of claim** prerequisite | A.R.S. § 12-821 + § 12-821.01 |

**Notes** (point to corpus — `az-law-references` `az-statutes-debt/` —
for the operative day counts and any tolling / discovery-rule text;
this skill does not hardcode them):

- The **public-entity 1-year SOL** (A.R.S. § 12-821) is far shorter
  than the general 2-year clock and runs alongside the **180-day
  notice of claim** (A.R.S. § 12-821.01). Treat any government
  defendant as a SOL emergency.
- Arizona recognizes a **discovery rule** for accrual in some claims
  (e.g., latent medical-malpractice injury) — confirm accrual and any
  minority / unsound-mind tolling in corpus before relying on a
  filing date.
- The statutory **dog-bite strict-liability** action and a **common-
  law** negligence dog-bite action carry **different** limitation
  periods — confirm which clock applies in corpus.

## Pure comparative negligence — A.R.S. § 12-2505

Arizona is a **pure comparative negligence** jurisdiction. This is a
distinctive, plaintiff-favorable feature — flag it clearly:

- **A.R.S. § 12-2505(A)** — "the claimant's action is **not barred**,
  but the full damages shall be **reduced in proportion to the
  relative degree of the claimant's fault**." A plaintiff who is
  **80% at fault still recovers 20%** of their damages. There is **no
  50% bar** and **no greater-than-defendant bar** — contrast the
  modified / 51%-bar systems used in most states.
- **The only carve-out** is for a claimant who **intentionally,
  wilfully, or wantonly** caused or contributed to the injury or
  wrongful death — that claimant has **no right** to comparative
  apportionment (A.R.S. § 12-2505(A)).
- Fault is assessed by the trier of fact and applied across **all**
  contributing actors, including nonparties (see § 12-2506 below).

## Several liability and nonparty at fault — A.R.S. § 12-2506

Arizona **abolished joint-and-several liability** for most tort
actions. The apportionment regime is the structural heart of Arizona
tort defense:

- **A.R.S. § 12-2506(A)** — "Each defendant is liable **only** for
  the amount of damages allocated to that defendant **in direct
  proportion to that defendant's percentage of fault**." The court
  enters **separate, several judgments** reflecting each defendant's
  proportionate share. There is no contribution among tortfeasors in
  the ordinary case because no one overpays its share.
- **A.R.S. § 12-2506(B) — nonparty at fault.** The fault of a
  **nonparty** may be considered in the allocation **if** the
  plaintiff settled with that nonparty **or** the defending party
  gives **notice before trial** identifying the nonparty and the
  basis for attributing fault. The mechanics — content and the
  **deadline** — are governed by **Ariz. R. Civ. P. 26(b)** (the
  notice of nonparty at fault). Missing the rule's deadline forfeits
  the ability to point the jury at the absent actor.
- **A.R.S. § 12-2506(D) — exceptions (joint liability survives).**
  Defendants remain **jointly** liable where they (1) **acted in
  concert**, (2) one acted as the **agent or servant** of the other,
  or (3) liability arises under the **federal Employers' Liability
  Act**. These are narrow — confirm the current list in corpus.

**Strategic upshot:** because each defendant pays only its allocated
share and the defense can shift fault onto empty chairs, **finding
and joining every solvent at-fault actor** — and **policing the
nonparty-at-fault notice** under Rule 26(b) — drives recovery in
Arizona multi-defendant cases.

## NO damage caps — the constitutional prohibition

**Arizona has no statutory cap on damages of any kind** — no
non-economic cap, no medical-malpractice cap, no punitive cap by
statute. This is a **constitutional** rule, not merely a legislative
choice, and it is the single most distinctive feature of Arizona tort
law:

- **Ariz. Const. art. 2, § 31** — "**No law shall be enacted in this
  state limiting the amount of damages to be recovered for causing
  the death or injury of any person.**"
- **Ariz. Const. art. 18, § 6** — "**The right of action to recover
  damages for injuries shall never be abrogated, and the amount
  recovered shall not be subject to any statutory limitation.**"

Together these provisions **forbid the Arizona legislature from
capping** injury or wrongful-death damages. Any attempt to impose a
damages cap by statute is unconstitutional. (Both provisions carry a
narrow carve-out for persons injured while attempting or engaged in
felony conduct.) Do **not** import another jurisdiction's cap
framework — in Arizona, plead **uncapped** economic and non-economic
damages.

## Medical malpractice — A.R.S. § 12-561 et seq.

Health-care liability is governed by A.R.S. Title 12, Chapter 5.1
("Actions Relating to Health Care," § 12-561 et seq.). Note that
**there is no damages cap** (above) — the gating issues are the
**expert affidavit** and **expert qualification** requirements:

### Preliminary expert opinion affidavit — A.R.S. § 12-2603

- **§ 12-2603(A)** — the claimant must **certify in a written
  statement filed and served with the claim** whether or not expert
  opinion testimony is necessary to prove the standard of care or
  liability.
- **§ 12-2603(B)** — if the claimant certifies that expert testimony
  **is** necessary, the claimant must **serve a preliminary expert
  opinion affidavit with the initial disclosures** required by
  **Ariz. R. Civ. P. 26.1**. The affidavit must address the expert's
  qualifications, the standard of care, the manner of breach, and how
  the breach caused the injury (confirm the statutory element list in
  corpus).
- A defective or missing affidavit exposes the claim to dismissal —
  treat it as an early case-dispositive gate.

### Expert qualifications — A.R.S. § 12-2604

The standard-of-care expert must satisfy Arizona's **matching-
specialty** rule — broadly, the expert must specialize in the **same
specialty** as the defendant (or, if the defendant is board-certified,
be **board-certified** in that specialty) and, during the year
immediately before the alleged malpractice, have devoted a majority
of professional time to **active clinical practice** or to
**instruction** of students in that specialty. Confirm the exact
qualification text in corpus before relying.

## Public entities — the notice of claim and 1-year SOL

Claims against the State, counties, cities, school districts, and
public employees are governed by A.R.S. Title 12, Article 2 — and the
prerequisites are **strict** and **commonly fatal**:

- **A.R.S. § 12-821.01 — 180-day notice of claim.** A person with a
  claim against a public entity, public school, or public employee
  must **file a notice of claim within 180 days** after the cause of
  action accrues. The notice must contain **facts sufficient to
  permit the entity to understand the basis of liability** and a
  **specific amount for which the claim can be settled** together
  with **facts supporting that amount**. **A claim not filed within
  180 days is barred** — Arizona courts enforce this strictly, and a
  defective sum-certain demand can sink the claim.
- **A.R.S. § 12-821 — 1-year SOL.** Even after a timely notice of
  claim, the lawsuit itself must be filed **within one year** after
  the cause of action accrues — half the general 2-year clock.
- **Calendar both clocks separately at intake.** A government
  defendant turns a routine PI matter into a deadline emergency: the
  180-day notice runs first, the 1-year suit clock runs alongside it.

## Dog-bite liability — A.R.S. §§ 11-1025 / 11-1020

- **A.R.S. § 11-1025(A) — strict liability.** The owner of a dog that
  **bites a person** in a public place or while the person is
  **lawfully** in or on a private place (including the owner's
  property) is **liable for damages "regardless of the former
  viciousness of the dog or the owner's knowledge of its
  viciousness."** No "one free bite" rule applies to the statutory
  action.
- **A.R.S. § 11-1020** — companion provision imposing liability on a
  person who allows a **dog to be at large** for any resulting injury
  to person or property (broader than a bite); confirm the interaction
  with § 11-1025 in corpus.
- **Provocation defense** — § 11-1025 cross-references the definition
  of "provocation" (see A.R.S. § 11-1027); provocation is the
  principal statutory defense.
- Distinguish the **statutory strict-liability** action from a
  **common-law negligence** dog-bite claim — they carry different
  limitation periods (see SOL catalog).

## Uninsured / underinsured motorist (UM/UIM)

In auto cases, **UM/UIM coverage** under the injured person's own (or
a resident relative's) policy is a frequent secondary recovery source
where the at-fault driver is uninsured or under-insured:

- Confirm the policy limits, any required **written rejection /
  selection** of UM/UIM coverage, and the **stacking** rules.
- UM/UIM claims are often **contractual** and may carry **policy /
  contractual** notice and suit deadlines distinct from the tort SOL —
  read the policy and confirm the operative limitation in corpus.

## High-yield Arizona PI checks

1. **What's the SOL?** General PI **2 years** (A.R.S. § 12-542).
   Public-entity defendant → **1 year** (§ 12-821) **+ 180-day notice
   of claim** (§ 12-821.01). Dog-bite statutory vs. common-law clock?
2. **Comparative fault?** Arizona is **PURE** — plaintiff recovers
   even if **more than 50%** at fault (A.R.S. § 12-2505), reduced by
   fault share. Only intentional/wilful/wanton conduct forfeits
   apportionment.
3. **Multiple actors?** Several liability only (A.R.S. § 12-2506(A));
   each defendant pays its own share. Watch for a defense **notice of
   nonparty at fault** under § 12-2506(B) / **Ariz. R. Civ. P. 26(b)**
   — and join every solvent at-fault actor.
4. **Damages?** **No caps** — plead uncapped non-economic and economic
   damages (Ariz. Const. art. 2 § 31 + art. 18 § 6). Do not import
   another jurisdiction's cap.
5. **Medical malpractice?** Certify under **§ 12-2603(A)**; serve the
   **preliminary expert opinion affidavit** with Rule 26.1 initial
   disclosures (**§ 12-2603(B)**); confirm the expert satisfies the
   matching-specialty rule (**§ 12-2604**).
6. **Public defendant?** **180-day notice of claim** with a sum-
   certain settlement demand and supporting facts (§ 12-821.01); **1-
   year suit clock** (§ 12-821). Both strict.
7. **Dog bite?** Statutory strict liability (§ 11-1025) — owner liable
   regardless of prior viciousness; assess the provocation defense
   (§ 11-1027).
8. **Auto case?** UM/UIM coverage available? Policy limits, selection
   / rejection, stacking, contractual notice deadlines?

## Drafting checklist

- [ ] Confirm the **2-year SOL** (or the **1-year** public-entity
      clock) is not running out within 30 days; calendar the **180-day
      notice of claim** separately for any government defendant.
- [ ] Plead **pure comparative negligence** awareness — recovery is
      reduced, **never barred**, by plaintiff's fault share (A.R.S.
      § 12-2505).
- [ ] Identify and **join every at-fault actor**; track the defense
      **notice of nonparty at fault** (A.R.S. § 12-2506(B) / Ariz. R.
      Civ. P. 26(b)) and move to add necessary defendants.
- [ ] In the damages prayer, plead **uncapped** economic **and** non-
      economic damages — Arizona's Constitution bars statutory caps
      (art. 2 § 31 + art. 18 § 6). Do not hardcode any cap.
- [ ] For **medical malpractice**, file the **§ 12-2603(A)
      certification** with the complaint and serve the **preliminary
      expert opinion affidavit** with the Rule 26.1 initial
      disclosures; confirm the expert meets **§ 12-2604**.
- [ ] For a **public defendant**, serve the **§ 12-821.01 notice of
      claim** within 180 days with a **specific settlement amount and
      supporting facts**, then file suit within the **1-year**
      § 12-821 window.
- [ ] For a **dog bite**, plead **§ 11-1025** strict liability and
      anticipate the **provocation** defense (§ 11-1027).
- [ ] In an **auto** case, identify any **UM/UIM** coverage and its
      separate contractual deadlines.
