Arizona Tort Reform laws determine how much time you have to file a mass tort claim, whether your state caps the damages you can recover, and how your own fault percentage affects your payout.
This Arizona tort reform guide covers every rule that matters if you are considering a mass tort lawsuit — statute of limitations deadlines, damage caps, comparative fault, and which major active lawsuits affect Arizona residents the most. Understanding Arizona tort reform before you talk to a lawyer helps you know what to expect.

In This Arizona Tort Reform Guide:
Arizona Tort Reform Statute of Limitations
The statute of limitations is the deadline to file a lawsuit. Under Arizona tort reform rules, the time limit depends on the type of injury. Missing your deadline means you lose your right to sue entirely, regardless of how strong your case may be.
| Injury Type | Time Limit |
|---|---|
| Personal Injury | 2 years from date of injury under A.R.S. section 12-542. |
| Wrongful Death | 2 years from date of death under A.R.S. section 12-542. Same tolling rules for minors and government notice requirements apply. |
| Product Liability | 2 years from discovery under A.R.S. section 12-542, subject to a 12-year statute of repose under A.R.S. section 12-551. |
| Medical Malpractice | 2 years under A.R.S. section 12-542(1). |
Personal injury details: For minors under A.R.S. section 12-502, the SOL is tolled during minority and the minor has 2 years after turning 18 to file. For government defendants, a 180-day notice of claim must be filed under A.R.S. sections 12-821 and 12-821.01 before any lawsuit can proceed; failure to file within 180 days permanently bars the claim.
Product liability details: Same tolling rules for minors apply.
Medical malpractice details: Discovery rule applies per Kenyon v. Hammer — clock starts when plaintiff knew or should have known of both the injury AND its negligent cause. Plaintiffs must file an expert affidavit under A.R.S. section 12-2603 within 30 days after defendant files a response (or 60 days of complaint). Same tolling rules for minors apply.
Discovery rule: YES — Arizona applies a discovery rule under Kenyon v. Hammer. The statute of limitations begins when the plaintiff knew or through reasonable diligence should have known of both (1) the fact of injury AND (2) the negligent cause. Both prongs must be satisfied before the clock starts.
Statute of repose: YES — Product liability: 12 years after the product was first sold for use or consumption under A.R.S. section 12-551. Exceptions: claims based on negligence or breach of express warranty are NOT barred by the repose period. Construction defects: 8 years after substantial completion under A.R.S. section 12-552, with a latent defect exception allowing claims discovered in year 8 to be filed during year 9.
These Arizona tort reform deadlines apply to most mass tort claims. However, some MDLs have their own rules — for example, the Camp Lejeune Justice Act created a special two-year filing window.
Always verify your specific deadline with a licensed attorney, as Arizona tort reform statutes may have exceptions not listed here.
Arizona Tort Reform Damage Caps
Damage caps limit how much money you can recover in a lawsuit, even if a jury awards you more. Arizona tort reform damage cap rules affect mass tort settlements and verdicts directly.
Understanding these limits helps you set realistic expectations for potential compensation under Arizona tort reform law.
| Damage Type | Cap |
|---|---|
| Non-Economic (Pain & Suffering) | NO CAP — Arizona constitutionally prohibits damage caps under Article 2 Section 31 (no law shall limit damages for death or injury), Article 18 Section 6 (right of action and amount shall not be subject to statutory limitation), and Article 2 Section 23 (right to jury trial). |
| Punitive Damages | NO CAP on punitive damages generally. |
| Total Damages | NO CAP — Arizona constitutionally prohibits any overall cap on damages. |
| Medical Malpractice | SAME AS GENERAL — Arizona has no special medical malpractice damage cap. |
Non-economic damages details: Any cap would require a constitutional amendment.
Punitive damages details: However, two important restrictions: (1) no punitive damages against public entities or government agencies, and (2) under A.R.S. section 12-689 (HB 2503, effective 2012), punitive damages cannot be awarded in product liability cases where the product complied with government agency approval, clearance, or license (including FDA approval and 510k clearance), unless the manufacturer intentionally withheld or misrepresented material information.
Medical malpractice cap details: The constitutional prohibition on damage caps applies equally to medical malpractice claims.
Arizona tort reform caps can significantly reduce your recovery in a mass tort case. If Arizona caps non-economic damages, your pain and suffering award is limited regardless of injury severity.
Some caps have been challenged as unconstitutional in Arizona courts — check with a local attorney for the current status of any Arizona tort reform cap.
Arizona Tort Reform Comparative Fault Rule
Comparative fault determines whether you can recover damages if you share some responsibility for your injuries. Under Arizona tort reform rules, defendants in mass tort cases often argue that the plaintiff contributed to their own harm (for example, by continuing to use a product after a recall).

Arizona follows a pure comparative fault system. This means you can recover damages even if you are mostly at fault for your injuries. However, your compensation is reduced by your percentage of fault. For example, if you are found 70% at fault and your damages are $100,000, you would recover $30,000.
Under pure comparative fault, a plaintiff’s recovery is reduced by their percentage of fault with no threshold bar. If a plaintiff is 30 percent at fault and damages are 100000, recovery is 70000. If a plaintiff is 50 percent at fault, recovery is 50000. If a plaintiff is 51 percent at fault, recovery is 49000. Even at 99 percent fault, the plaintiff recovers 1 percent. Exception: comparative fault does NOT apply to reduce damages for any party whose conduct was intentional, willful, or wanton.
Joint and several liability: Pure several liability — joint and several liability was abolished in 1987 under A.R.S. section 12-2506 (effective 1988). Each defendant is liable only for damages in direct proportion to that defendant’s percentage of fault. Three exceptions where joint and several still applies: (1) parties acting in concert, (2) agent or servant relationship, (3) claims under the Federal Employers Liability Act.

Arizona Tort Reform Legislation
1. A.R.S. section 12-2506 (1987) — Abolished joint and several liability, replaced with pure several liability in personal injury, property damage, and wrongful death actions. 2. HB 2503 (2012, codified as A.R.S. section 12-689) — Bars punitive damages for products manufactured and sold in compliance with government agency approval including FDA approval and 510k clearance, unless manufacturer intentionally withheld or misrepresented material information.
Expanded 1989 law that applied only to drugs. 3. HB 2603 (asbestos transparency) — Requires personal injury plaintiffs with asbestos-related illnesses to produce sworn testimony about trust claims to prevent double recovery.
4. Medical malpractice apology law — Allows doctors to express apology, compassion, or condolence without statements being used as evidence of liability. 5. Arizona Constitution Article 2 Section 31 and Article 18 Section 6 — Constitutional provisions prohibiting any legislative caps on damages, making sweeping tort reform virtually impossible without a constitutional amendment.
These Arizona tort reform laws directly affect how mass tort claims are filed, what damages you can recover, and how long you have to act.
Always verify the current status of any law with the Arizona State Bar Association or a licensed attorney.
Additional Arizona Tort Rules

Government claims notice requirement — A.R.S. sections 12-821 and 12-821.01 require a formal written notice of claim filed within 180 days of injury before suing any city, county, state agency, or school district. Must include sufficient facts and a specific settlement dollar amount. Failure to file permanently bars the claim. 2. Medical malpractice expert affidavit — A.R.S. section 12-2603 requires plaintiffs to certify whether expert testimony is needed and serve a preliminary expert affidavit within 30 days of defendant’s response (or 60 days of complaint).
3. FDA/government approval shield — A.R.S. section 12-689 provides immunity from punitive damages for government-approved products. 4. Asbestos trust transparency — Plaintiffs must disclose all asbestos trust claims under oath. 5.
