Arizona Statute of Limitations for Civil Cases
Arizona Statutes of Limitations for Civil Cases
Arizona's statute of limitations framework governs how long plaintiffs have to file civil lawsuits. These deadlines are strictly enforced—missing them typically results in dismissal and permanent loss of the right to sue. Understanding the correct limitations period for your specific cause of action is essential, as the time periods vary significantly across different claims.
Personal Injury
Limitation Period: 2 years
Statute Citation: A.R.S. § 12-542(1)
When the Clock Starts: The statute of limitations begins running when the injury occurs, not when the plaintiff discovers it (absent the discovery rule exception discussed below).
Personal injury claims include injuries caused by negligence, such as slip-and-fall accidents, motor vehicle collisions, and premises liability. This is one of Arizona's most common limitation periods and applies broadly to negligence-based torts.
Breach of Written Contract
Limitation Period: 6 years
Statute Citation: A.R.S. § 12-548(1)
When the Clock Starts: The statute of limitations begins running when the breach occurs. For contracts requiring continuing performance, the clock starts when the last performance was due or when the breach is discovered.
Written contracts receive longer protection than personal injury claims. This includes purchases, service agreements, construction contracts, and lease agreements with written terms. Arizona courts strictly construe what constitutes a "written" contract—handwritten agreements, emails, and signed documents all qualify.
Breach of Oral Contract
Limitation Period: 3 years
Statute Citation: A.R.S. § 12-543(1)
When the Clock Starts: The statute of limitations begins running when the breach occurs.
Oral contracts receive less protection than written contracts due to evidentiary concerns. Arizona requires clear and convincing evidence to establish an oral contract, but once established, the 3-year clock applies from the date of breach. This category commonly includes verbal agreements for services, employment arrangements, and informal loan agreements.
Fraud
Limitation Period: 3 years
Statute Citation: A.R.S. § 12-543(2)
When the Clock Starts: The statute of limitations begins running when the plaintiff discovers the fraud or reasonably should have discovered it. Arizona courts apply the discovery rule to fraud claims, providing an exception to the general rule that the clock starts upon the wrongful act itself.
Fraud claims require proof of a false statement, knowledge of its falsity, intent to induce reliance, reasonable reliance, and damages. Because fraudulent conduct is often hidden, Arizona recognizes that plaintiffs may not immediately discover the deception. However, the discovery rule has limits—it does not extend the period indefinitely if the plaintiff failed to exercise reasonable diligence.
Property Damage
Limitation Period: 3 years
Statute Citation: A.R.S. § 12-543(1)
When the Clock Starts: The statute of limitations begins running when the damage to the property occurs.
Property damage includes destruction or diminution of real or personal property caused by negligence or intentional acts. This encompasses damage from accidents, natural disasters, vandalism, and trespass. Unlike personal injury (which has a 2-year period), property damage receives a 3-year window under Arizona law.
Medical Malpractice
Limitation Period: 2 years from discovery; subject to a repose period
Statute Citation: A.R.S. § 12-542(2)
When the Clock Starts: The statute of limitations begins running when the plaintiff discovers (or reasonably should have discovered) the injury caused by the malpractice, with one critical exception.
Repose Period (Hard Cap): No action may be brought more than 3 years after the negligent act or omission, regardless of discovery date (A.R.S. § 12-542(2)). This repose period applies even if the plaintiff never discovered the injury within the 2-year period.
Medical malpractice claims involve errors or omissions by healthcare providers. Arizona's discovery rule provides some protection, recognizing that patients may not immediately realize they received negligent treatment. However, the 3-year absolute repose period ensures finality. For example, if a surgeon leaves a sponge inside a patient during surgery on January 1, 2022, the claim must be filed by January 1, 2025, even if the patient doesn't discover the sponge until 2026.
Additionally, Arizona imposes certificate of merit requirements (A.R.S. § 12-864). Plaintiffs must file an affidavit from a qualified healthcare provider establishing the defendant's deviation from the standard of care before or within 60 days after filing the complaint.
Wrongful Death
Limitation Period: 2 years
Statute Citation: A.R.S. § 12-542(1)
When the Clock Starts: The statute of limitations begins running from the date of death.
Wrongful death claims are brought by the decedent's estate or surviving family members when a person's death is caused by another's negligence or wrongful act. Arizona treats these as derivative claims, so the limitation period is tied to the date of death, not when the family member discovers the death.
Defamation, Libel, and Slander
Limitation Period: 1 year
Statute Citation: A.R.S. § 12-541(1)
When the Clock Starts: The statute of limitations begins running from the date of publication or utterance of the defamatory statement.
Defamation claims require proof of a false factual statement communicated to third parties that damages the plaintiff's reputation. Libel is written defamation; slander is spoken defamation. Arizona's 1-year period is shorter than most states and reflects the policy that media defendants and publishers deserve timely notice of claims. This is one of Arizona's most restrictive limitation periods.
Trespass
Limitation Period: 3 years
Statute Citation: A.R.S. § 12-543(1)
When the Clock Starts: The statute of limitations begins running when the unauthorized entry or occupation occurs.
Trespass to real property includes unlawful entry, unauthorized use, or remaining on another's land without permission. Trespass to personal property (conversion or interference with possessory rights) also uses the 3-year period. Unlike some jurisdictions, Arizona does not have a separate, extended period for trespass claims, even when the trespasser's occupation is ongoing or hidden.
Debt Collection and Promissory Notes
Limitation Period: 6 years
Statute Citation: A.R.S. § 12-548(1) (general contract provision); A.R.S. § 12-543(1) (account stated, implied contract)
When the Clock Starts: The statute of limitations begins running when the debt becomes due or when the last payment was made.
Debt collection actions include enforcement of promissory notes, credit card debt, personal loans, and judgment notes. Arizona distinguishes between written promissory notes (6 years under A.R.S. § 12-548(1)) and oral debt agreements or account stated (3 years under A.R.S. § 12-543(1)). Creditors must file suit within these periods; after expiration, the debt is generally unenforceable in court, though the creditor may still pursue non-judicial collection efforts.

The Discovery Rule and Delayed Accrual
Arizona recognizes a discovery rule exception that delays the accrual of certain claims. Under this doctrine, the statute of limitations begins running when the plaintiff discovers (or reasonably should have discovered) the injury, not when the wrongful act occurred.
Causes of Action Governed by the Discovery Rule:
Causes of Action NOT Governed by the Discovery Rule:
Key Limitation: Even with the discovery rule, plaintiffs must exercise reasonable diligence. Courts will not extend deadlines indefinitely if the plaintiff negligently failed to investigate or discover the injury. Additionally, medical malpractice remains subject to the 3-year repose period regardless of discovery.

Tolling Provisions
Arizona law provides several circumstances under which the statute of limitations is tolled (paused), extending the filing deadline:
Minority
Statute Citation: A.R.S. § 12-502
If the plaintiff is under 18 years old when the cause of action accrues, the statute of limitations does not begin running until the plaintiff reaches age 18. This protection applies even if a parent or guardian could have filed suit on the minor's behalf.
Mental Incapacity
Statute Citation: A.R.S. § 12-502
If the plaintiff is mentally incapacitated and has no legal guardian, the statute of limitations is tolled during the period of incapacity. Mental incapacity typically means the plaintiff lacks the legal and mental capacity to understand the proceedings.
Absence from Arizona
Statute Citation: A.R.S. § 12-501
If the defendant is absent from Arizona and has no agent within the state authorized to accept service of process, the time of the defendant's absence is not counted toward the statute of limitations. This tolling applies only to defendants who have left Arizona; it does not toll for absent plaintiffs.
Military Service
Arizona does not have a specific military service tolling statute. However, federal law (50 U.S.C. § 3953, Servicemembers Civil Relief Act) may provide tolling for active duty service members in certain circumstances.
Fraud-Related Tolling
For fraud claims, tolling may apply if the defendant's fraud actively conceals the plaintiff's ability to discover the claim. This is a narrow exception and requires clear evidence that the defendant's fraudulent conduct prevented discovery.

Arizona-Specific Rules and Exceptions
Continuing Violation Doctrine
Arizona recognizes a continuing violation doctrine in limited circumstances. When a defendant's wrongful conduct is ongoing or repeated, the statute of limitations may restart with each new violation. This typically applies to employment discrimination and systematic fraud, but courts apply it narrowly.
Substantial Completion in Construction
For construction defect claims, the statute of limitations for latent defects may be tolled until the project achieves substantial completion. Arizona courts have applied the discovery rule to construction defects, recognizing that hidden defects may not be apparent at the time of completion.
Contractual Waivers
Arizona allows parties to contractually shorten the statute of limitations by agreement, but generally does not enforce provisions that eliminate limitations periods entirely or reduce them below the statutory minimum in certain contexts (particularly consumer contracts).

What Happens When You Miss the Deadline
Dismissal: If a defendant timely raises the statute of limitations defense, the court will dismiss the claim. Dismissal is typically granted on a motion to dismiss or motion for summary judgment and is often rendered without reaching the merits of the case.
Permanent Loss of Claim: Once the statute of limitations expires, the right to sue is generally permanently extinguished. There are no "second chances" to file, and courts do not have discretion to extend expired periods (except in rare circumstances involving fraud or active concealment).
Partial Defense: In some cases, a statute of limitations bar may apply only to a portion of a claim if different events occurred at different times.

How to Calculate Accurately
Start Date: Identify precisely when the cause of action accrued. For most claims, this is the date of the injury, breach, or wrongful act. For fraud and medical malpractice, use the discovery date or when the plaintiff reasonably should have discovered the injury.
Tolling: Determine whether any tolling provisions apply (minority, mental incapacity, defendant's absence, etc.). Subtract tolled periods from the calculation.
End Date: Add the applicable statute of limitations period to the start date. For example, a 2-year personal injury claim arising on January 15, 2023, must be filed by January 15, 2025.
Filing Deadline: The deadline is the last day of the calculated period. Filing on the last permissible day is acceptable; filing the next day results in dismissal. Many practitioners file several days early to avoid errors.
Tolling Documentation: Keep careful records of any events affecting tolling (birth certificates for minority tolling, medical records for discovery dates, etc.).
