How Long Do You Have to File an Arizona Small Claims Case?

This is one of the procedures covered in Small Claims in Arizona Justice Courts. The small claims division of justice court accepts cases up to $5,000 under A.R.S. § 22-503, but only if the underlying claim is still alive under Arizona’s statutes of limitations. The same time limits that apply to a superior court lawsuit apply here, and a defendant who shows the case was filed too late can ask the hearing officer to dismiss it.

How Arizona counts the time

A statute of limitations is the deadline for filing a lawsuit. In Arizona, most limitation periods start on the date the cause of action “accrues”, meaning the date the plaintiff has a legal right to sue, even if they do not know it yet.

For an unpaid debt, the cause of action usually accrues on the date the first payment was missed or the day the account went into default. For property damage or personal injury, accrual is the date of the injury. For fraud, A.R.S. § 12-543 sets a discovery rule: the three-year clock does not start until the aggrieved party discovers the facts that constitute the fraud or mistake.

The deadline cuts off the right to file in any Arizona civil court, including small claims. A complaint filed one day late is a complaint that can be dismissed if the defendant raises the statute of limitations as a defense.

Deadlines by claim type

Arizona’s general civil statutes of limitations are in Title 12, Chapter 5 of the Arizona Revised Statutes. The deadlines that come up most often in small claims cases are these:

• Six years for a debt founded on a written contract executed in Arizona, or a credit card balance, under A.R.S. § 12-548. This is the longest deadline in routine small claims practice and applies to most signed loan agreements and retail credit card accounts.
• Three years for a debt not evidenced by a written contract (an oral agreement), for stated or open accounts, and for claims of fraud or mistake, under A.R.S. § 12-543. Fraud claims run from the date of discovery, not the date of the underlying conduct.
• Two years for personal injury, property damage, conversion, and trespass under A.R.S. § 12-542. This category covers most fender-benders and disputes over damaged or wrongfully kept personal property.
• One year for malicious prosecution, false imprisonment, certain liabilities created by statute, and wrongful termination under A.R.S. § 12-541. Libel and slander are also one-year claims, but small claims cannot hear them. The next section covers what is excluded.

A few specialized actions have a four-year limit under A.R.S. § 12-544, including partnership accounting disputes and judgments rendered outside Arizona. Sale-of-goods claims governed by Article 2 of the Uniform Commercial Code follow the four-year rule in A.R.S. § 47-2725 rather than the contract limit in § 12-548.

Claims small claims cannot decide

Arizona’s small claims division has narrower subject-matter jurisdiction than justice court generally. Under A.R.S. § 22-503, the small claims division cannot hear:

• Actions for defamation by libel or slander
• Forcible entry, forcible detainer, or unlawful detainer (eviction)
• Actions for specific performance
• Class actions
• Actions involving prejudgment remedies or injunctive relief
• Traffic violations and other criminal matters
• Actions against the state or its political subdivisions

The practical effect: even though defamation has a one-year deadline under A.R.S. § 12-541, a plaintiff with a defamation claim cannot file in the small claims division at all. The case belongs in the justice court’s regular civil division or in superior court, where the same one-year deadline still applies. Eviction has its own statutory framework outside small claims as well.

For a small claims plaintiff, the deadlines that matter are the six-year written-contract limit, the three-year oral-debt and open-account limit, and the two-year personal-injury and property-damage limit. Most claims that fit within the Arizona small claims $5,000 cap fall into one of these three buckets.

When the clock pauses or restarts

A few Arizona statutes change the running of the limitation period. Three come up often enough to be worth knowing.

Defendant absence from the state. Under A.R.S. § 12-501, the time a defendant spends outside Arizona does not count toward the limitation period. If a defendant moves to another state for two years and then returns, those two years are added back to the deadline.

Written acknowledgment of a debt. Under A.R.S. § 12-508, a debtor’s written, signed acknowledgment of an old debt can take the claim out of the statute of limitations. An oral promise is not enough; the acknowledgment must be in writing and signed by the party to be charged. Partial payments are sometimes argued to have the same effect, but the safer reading of the statute is that a written, signed acknowledgment is what removes the bar.

Minority or unsound mind. Tolling for plaintiffs who were under 18 or of unsound mind when the cause of action accrued exists under A.R.S. § 12-502, but the statute excludes actions in Article 2 of Chapter 5, which contains §§ 12-541 through 12-555. That exclusion covers the most common small claims deadlines: personal injury, debt, conversion, and written contracts. For those claims, the standard accrual date controls regardless of the plaintiff’s age at the time of injury.

What happens after the deadline passes

Arizona courts treat the statute of limitations as an affirmative defense, which means the defendant has to raise it. A defendant who answers the complaint, attends the hearing, and never mentions the deadline can waive the defense and lose on the merits.

When the defense is raised, the hearing officer or justice of the peace decides whether the claim is timely. The plaintiff carries the burden of showing the case was filed within the deadline once the defendant points to a missed cutoff. If the claim is found untimely, the case is dismissed.

A debt that is past the limitation period is sometimes described as “time-barred” rather than extinguished. The underlying obligation can still exist as a matter of contract; what the statute of limitations cuts off is the legal remedy. That distinction matters because a debt collector cannot sue on a time-barred debt, but a collector can sometimes still ask for voluntary payment. Federal law and Arizona consumer protection rules limit what collectors can say about an out-of-statute debt, and that question is separate from whether a small claims case can still be filed.
