Debt collection defense in Arizona small claims

Being sued over an alleged debt? Organize your defense.

If a creditor, debt buyer, or collector has sued you in small claims over an alleged debt, you can respond and defend yourself. Common defenses include the debt being past the statute of limitations, the amount being wrong, the plaintiff not proving they own the debt, or the debt not being yours at all. You do not have to face it disorganized.

In Arizona, small-claims cases are heard in the Small Claims Division of the Justice Court and you can sue for up to $5,000 (exclusive of interest and costs).

Debt collection defense: steps that matter

  1. Read the lawsuit carefully and note your deadline to answer — missing it can cause a default judgment against you.
  2. Ask the plaintiff (in writing, through the court process) to prove the debt: the original signed agreement, a full account history, and a clear chain showing they own the debt.
  3. Check the age of the debt against the statute of limitations below; a time-barred debt is a defense you can raise.
  4. Gather your own records — payments, disputes, and any prior correspondence — and keep them together with the court dates.

Filing your Small Claims Complaint (form LJSC00001F) in Arizona

  1. Confirm your claim qualifies. Your claim must be for $5,000 or less and a type small claims can hear (not eviction, defamation, or injunctive relief). File in the justice court precinct where the defendant lives (A.R.S. 22-202).
  2. Complete and file the Complaint and Summons. Fill out the Small Claims Complaint (LJSC00001F) and Summons (LJSC00002F) from the azcourts.gov forms hub and file them with the small claims division clerk. Pay the filing fee or request a fee waiver.
  3. Serve the defendant. Serve the summons and complaint by registered or certified mail; if mail service fails, use personal service. File proof of service with the court (A.R.S. 22-513).
  4. The defendant answers within 20 days. The defendant must answer within 20 days of service (A.R.S. 22-514). If they do not answer, you may seek a default judgment.
  5. Attend the hearing. A hearing officer or justice of the peace hears the case. You represent yourself; lawyers may take part only if both sides agree in writing. The decision is final.

Filing fees: Filing fees are set by each justice court and vary by precinct; confirm the amount with the court. A fee waiver or deferral is available if you cannot afford the costs.

Deadline that applies to your debt collection defense

A debt claim usually rests on a contract or account, so the statute of limitations for that kind of debt is the deadline the other side has to sue you. If the debt is older than this window, the limitations period can be a defense you raise.

Written contract or debt: 6 years (A.R.S. § 12-548)

Answering a lawsuit: The defendant must file an answer within 20 days after being served (A.R.S. 22-514). If they do not answer, you may seek a default judgment.

Serving the defendant: The plaintiff serves the summons and complaint by registered or certified mail; if that fails, personal service by a process server or authorized officer may be used, with an affidavit of service filed (A.R.S. 22-513).

Appeals: There is no appeal: a small-claims decision is final and binding (A.R.S. 22-519). To preserve appeal rights, a party must have the case transferred to the regular civil division of the justice court before the hearing.
