In Arizona, the law imposes strict time limits on a creditor’s ability to file a lawsuit to recover unpaid debts. These limits, known as statute of limitations, provide consumers with legal protection, resulting in time-barred debts. Understanding when a debt becomes “time-barred” is a must, particularly if you are facing collection efforts involving older obligations. That deadline can quietly become one of your strongest defenses, and may even save you from unnecessary panic caused by aggressive credit collectors. 

Meaning of Time-Barred Debts

Technically, time-barred debts may continue to exist in a practical or accounting sense. Just because the debt has surpassed a set amount of time does not mean that it is erased. However, the expiration of the statutory period can significantly limit the creditor’s legal remedies. Once this period lapses, the creditor is generally prohibited from initiating a lawsuit to enforce collection in court. Simply put, you still owe the money. The creditor can no longer file a lawsuit to pressure you to pay off the debt. 

In Arizona, the most common consumer debts, like credit cards, personal loans, and other written agreements, fall under a six-year statute of limitations. That rule comes directly from Arizona Revised Statutes § 12-548, which says a creditor must file a lawsuit within six years after the debt “accrues.”

When the Timeline Begins

A central issue in determining whether a debt is time-barred is identifying when the cause of action “accrues”. What triggers the statutory period? You might think the six years start when the account is charged off or sent to collections. 

But in Arizona, courts have clarified that the clock usually starts when you first miss a required payment and don’t catch up. Accrual typically occurs at the point of default – when a debtor first fails to make a required payment and does not subsequently cure that default. 

That means the timeline begins earlier than many people expect.

This principle was reinforced in Mertola, LLC v. Santos, 244 Ariz. 488 (2018). In this case, the Arizona Supreme Court held that the statute of limitations begins to run upon default. In this case, the credit card debt’s timeline did not start at a later date, such as charge-off or account acceleration. This piece of information is significant, as it often results in the limitations period expiring earlier than creditors or consumers might initially assume.

For example, let’s say you stopped paying your credit card in January 2019, and you never brought the account current again.

• The statute of limitations started running from January 2019.
• The creditor had until January 2025 to file a suit to collect debt against you.
• If the suit was not filed within the prescribed period, the debt is now time-barred. They can no longer take you to court for your debt due to prescription.

If the creditor did not file any legal action within the six-year period, the debt becomes time-barred. Hence, the creditor can no longer initiate an action and obtain a judgment through litigation. 

Different Debts, Different Timelines

Note, however, that not all debts are subject to the same limitations period. While written contracts are governed by the six-year rule, other categories differ.

Here’s a simple breakdown:

• Credit cards / written contracts: 6 years
• Oral agreements (no written contract): 3 years
• Judgments (after a creditor already wins in court): can be enforced longer (often 5–10 years, depending on renewal rules)

So if you’re dealing with older debt, the type of debt matters just as much as the age of it.

What Can Happen After the Deadline

Again, time-barred debts do not erase your obligation. Even after the statute of limitations expires:

• Creditors can still contact you
• They can still ask you to pay
• The debt can still appear on your credit report (up to 7 years)

But here’s what they cannot do anymore:

• Filing a lawsuit due to prescription
• Getting a court order to garnish your wages or levy your bank account (unless an order was released before the deadline)

That’s a huge difference, but creditors can still attempt to collect the debt through non-judicial means.

The Risk of Restarting the Statute of Limitations

Here’s where you need to be careful: certain actions may revive or restart the statute of limitations. Although the specific legal effect depends on the facts and applicable statutes, such as A.R.S. § 12-508, doing the following may accidentally revive old debts:

• Making a payment
• Signing a document that you are acknowledging the debt
• Bringing the account current

For example, your old debt became time-barred in 2025. Then in 2026, you pay $100 because a collector pressured you.

That small payment might restart the clock, giving the creditor a fresh six years to sue.

That’s why many consumer lawyers say: never pay or promise anything on an old debt until you understand its legal status.

If a collector contacts you about an old debt, be careful. 

1. Ask for the date of the last payment and the name of the original creditor.
2. Ask for written validation of the debt.
3. Do not make a token payment until you know whether it is time-barred.
4. If sued, file a response and assert the statute of limitations defense.
5. Keep records of letters, account statements, and payment history.

If You’re Sued on a Time-Barred Debt

Keep in mind that the statute of limitations is an affirmative defense. This means that if a creditor files a lawsuit on a time-barred debt, the court will not automatically dismiss the case. 

That means:

• If a creditor sues you on an old debt
• And you don’t respond or raise the defense
• The court could still enter a judgment against you

It is important to respond to any legal action, regardless of the perceived age of the debt; otherwise, you may lose it.

To illustrate:

You’re sued in 2025 for a debt from 2017.

• The debt is likely time-barred.
• But if you ignore the lawsuit, the creditor might still win by default.

Over time, evidence becomes more difficult to obtain, records may be lost, and witness recollections fade. The rule on prescription maintains a balance between the rights of creditors and the need to protect individuals from defending against stale or unreliable claims.
