How to Vacate a Default Judgment on a Debt Lawsuit in Arizona (Justice Court Rule 141)

If you missed the 20-day deadline to answer a debt collection lawsuit in Arizona Justice Court, the collector may have already obtained a default and, after that, a default judgment. That judgment can be used to garnish wages, freeze bank accounts, or place a lien on property. It feels final — but Arizona's Justice Court Rules of Civil Procedure provide a specific route to ask the court to set it aside: a motion under Rule 141(c).

The grounds for relief under Rule 141(c)

Rule 141(c) lists six recognized grounds a Justice Court can rely on to relieve a party from a final judgment, order, or proceeding. The most commonly used in debt collection cases are:

1. Mistake, inadvertence, surprise, or excusable neglect. You have a reasonable, good-faith explanation for missing the 20-day Answer deadline — for example, you never actually received the summons, you were hospitalized, or you reasonably (even if mistakenly) believed the matter had already been resolved.

2. Newly discovered evidence that, with reasonable diligence, could not have been discovered in time to file a motion for a new trial.

3. Fraud, misrepresentation, or other misconduct of an opposing party. For example, the collector's process server falsely certified that you were served ("sewer service"), or the collector misrepresented the amount owed or the chain of ownership of the debt.

4. The judgment is void. Most often raised when service of process was defective — if you were never properly served, the court never had personal jurisdiction over you, and the judgment can be void regardless of how much time has passed.

5. The judgment has been satisfied, released, or discharged — or a prior judgment it was based on has been reversed or vacated, or applying it going forward is no longer equitable.

6. Any other reason that justifies relief from the judgment — a catch-all ground the court has discretion to apply.

The deadline to file — and how Arizona differs from other states

Timing is where many people miss their chance. A Rule 141(c) motion must generally be filed within a reasonable time. For grounds 1–3 above (mistake/excusable neglect, newly discovered evidence, and fraud/misconduct), Arizona's Justice Court rule also imposes a hard outer limit: the motion must be filed no more than 6 months after the judgment or order was entered. Note that this 6-month cap is shorter than the 1-year cap used in some other states' equivalent rules — do not assume you have a full year. That 6-month cap does not apply to a motion arguing the judgment is void (ground 4) or already satisfied (ground 5) — those challenges can be raised later, though you should still move promptly once you learn of the judgment. Because the reasonable-time standard is fact-specific, do not wait — get advice from a licensed Arizona attorney or a legal aid organization as soon as you discover the judgment.

How the motion works, step by step

Step 1 — Get the case file. Contact the Justice Court where the case was filed and request the full case file, including the proof of service (affidavit of service). This document is often the key to a service-defect argument.

Step 2 — Identify your strongest ground. Review why you missed the 20-day deadline. Were you served at all? Was the address correct? Did you move? Match your facts to one or more of the six grounds above.

Step 3 — File the motion promptly. A motion under Rule 141(c) is filed in writing, in the same case, and must comply with the Justice Court Rules' motion-format requirements — including a specific notice to the other side of their 10 days to respond. It should identify the rule and the specific ground, and lay out the supporting facts.

Step 4 — Serve the motion. The motion must be served on the plaintiff (or its attorney) as required by the Justice Court Rules. The court may rule with or without a hearing, and will give at least 5 days notice if a hearing is set.

If wages or accounts are already affected

A pending default judgment can lead to wage garnishment or a bank account levy while your motion is being considered. Since Proposition 209 (effective December 5, 2022), Arizona caps wage garnishment at the lesser of 10% of disposable earnings or the amount over 60 times the minimum wage — see the guide linked below. Filing the motion to vacate does not automatically stop collection; ask the court about a stay of proceedings under Rule 142 while the motion is pending if collection has already started.

Why acting fast matters more than which ground you pick

The single biggest factor Justice Courts weigh in these motions is how quickly you acted once you learned about the judgment — and Arizona's 6-month outer cap on the most commonly used grounds makes speed even more important here than in states with a 1-year cap. If you believe a default judgment was entered against you in error, treat the clock as already running — gather the case file and get advice immediately.
