Statute of Limitations on Debt in Arizona: Time Limits by Type

The statute of limitations is the deadline for filing a lawsuit to collect a debt. In Arizona the length of that deadline depends on the kind of debt, and a separate set of rules controls when the clock starts, when it can be reset, and what a creditor can still do after time runs out. This is one of the debt-collection topics covered in Arizona’s consumer protection laws, which orients the broader framework of consumer rights and state agencies.

How long a creditor has to sue on debt in Arizona

Arizona sorts debts into a few categories, each with its own limitations period. The category turns on how the debt was created, not on the collector who currently holds it.

A written agreement carries the longest window. Under A.R.S. § 12-548, an action for a debt evidenced by a written contract executed in Arizona, or by a credit card account, must be filed within six years after the cause of action accrues. The 2011 amendment that added credit card accounts to this section is why most credit card debt in Arizona carries a six-year deadline rather than a shorter one.

Debts that were never put in a signed writing get less time. A.R.S. § 12-543 sets a three-year limit for a debt not evidenced by a written contract and for stated or open accounts. Verbal loans and ordinary open accounts fall here.

When no other statute assigns a period, the general limitation applies. A.R.S. § 12-550 requires most remaining civil actions to be brought within four years after the cause of action accrues. The Federal Trade Commission’s debt collection FAQs describe how these deadlines interact with a consumer’s rights when a collector makes contact.

When the clock starts and what can restart it

The limitations clock starts when the cause of action accrues. For most consumer debt, accrual happens when the account goes into default and is not brought current, which is usually tied to the date of the last payment or the first missed payment that was never cured. The federal Consumer Financial Protection Bureau explains this default-date starting point in its overview of the statute of limitations on a debt. Two things commonly reset or extend the period. A partial payment on the account can restart the clock from the date of that payment. A written, signed acknowledgment of the debt can also keep the claim alive: under A.R.S. § 12-508, an acknowledgment of the justness of a claim after it became due does not revive a time-barred action unless the acknowledgment is in writing and signed by the party to be charged. An oral promise to pay, standing alone, does not meet that standard.

What a time-barred debt means for you

A debt whose limitations period has expired is called time-barred. The obligation does not disappear; it simply loses the backing of an enforceable lawsuit. A collector may still contact a consumer about a time-barred debt and ask for payment, but cannot win a court judgment if the debtor raises the expired deadline.

The federal Fair Debt Collection Practices Act limits what collectors may do with these accounts. The Consumer Financial Protection Bureau’s guidance on the statute of limitations on a debt notes that suing or threatening to sue on debt the collector knows is time-barred can violate federal law. A consumer who believes a collector is pursuing an expired debt improperly can report the collector to the Federal Trade Commission, which enforces the federal debt collection rules. Because the deadline is a defense rather than an automatic bar, it only takes effect if the person being sued brings it up. A defendant who ignores a lawsuit on a time-barred debt can still lose by default, which converts the expired debt into a collectible judgment. ## Raising the statute of limitations in a debt lawsuit In Arizona the statute of limitations is an affirmative defense. That means it is not applied on the court’s own initiative; the person being sued has to plead it in a written response, or it is treated as waived.

1. Pin down the date of first default

   Identify when the account went delinquent and was never brought current. This date, often the last-payment date, is what the limitations period counts from. Statements, the original creditor’s records, and the collector’s account documents all help establish it.

2. Match the debt to its limitations period

   Determine which statute governs. A written contract or credit card account runs six years under A.R.S. § 12-548; an oral debt or open account runs three years under A.R.S. § 12-543; anything else defaults to four years under A.R.S. § 12-550.

3. File a written answer that raises the defense

   An affirmative defense must appear in the written response to the complaint. A defendant who does not respond by the deadline stated in the summons risks a default judgment, and one who answers without asserting the expired deadline can be treated as having given it up.

4. Bring the supporting records to the hearing

   The date of last activity is the central fact. Documentation showing when the account defaulted supports the defense if the creditor disputes the timeline.

Cases with contested facts, large balances, or unusual account histories can involve questions of law that a licensed Arizona attorney is positioned to evaluate. The State Bar of Arizona maintains a lawyer referral service for finding representation in a specific practice area.

Why a court judgment outlasts the original debt

Once a creditor sues and wins, the resulting judgment has its own, much longer life. Under A.R.S. § 12-1551, a judgment creditor may have a writ of execution issued at any time within ten years after entry of the judgment, and within ten years after any renewal. A judgment can be renewed by affidavit or by a new action before that ten-year window closes, which can extend enforcement well beyond the original debt’s limitations period.

This is why responding to a lawsuit matters even on an old account. The three-, four-, or six-year deadline governs the window to sue, but a judgment entered inside that window resets the exposure to a ten-year, renewable enforcement period covering wage garnishment, bank levies, and liens.
