Sued in Arizona Small Claims Court?
What to do if you've been served with a small claims summons in Arizona — how to respond, defend yourself, countersue, and appeal.
Being sued in small claims court can feel overwhelming — but Arizona's process is designed for everyday people, not lawyers. Most cases are resolved in a single hearing lasting 15–30 minutes. This guide walks you through every step from receiving the summons to the hearing, and explains your options if you lose.
Step-by-Step: What to Do as a Defendant
Read the summons carefully
Your summons will state the claim amount, the plaintiff's name, and your hearing date. Note the date, time, and courthouse location. In Arizona, the small claims court is the Justice Court.
Don't ignore it — respond or appear
You generally don't need to file a written response in Arizona small claims — you just need to appear at the hearing. However, if you plan to file a counterclaim, do that in advance. Ignoring the summons results in a default judgment against you.
Gather your evidence
Collect everything that supports your version of events: contracts, receipts, invoices, text messages, emails, photos, bank statements, and any written communications. Organize them chronologically and make 3 copies — for the judge, the plaintiff, and yourself.
Consider filing a counterclaim
File a written counterclaim before the hearing. If your counterclaim exceeds $3,500, the case may be transferred to regular civil court. A counterclaim lets you seek money from the plaintiff in the same hearing, which can be a powerful negotiating tool.
Know the rules on attorneys
Attorneys generally cannot represent parties in Arizona Justice Court small claims proceedings. Both sides are on equal footing, which is actually an advantage for a well-prepared defendant.
Attend the hearing and present your defense
Be on time. When it's your turn, calmly present your evidence and explain why you don't owe what the plaintiff is claiming. Stick to facts — judges have little patience for emotional arguments. Keep your statements focused on the specific dispute.
Appeal within 30 days if you lose
If judgment is entered against you, you have 30 days to file an appeal with the Superior Court (trial de novo). Appeals in most states require a filing fee and result in a new trial (de novo). Act quickly — missing this deadline means the judgment becomes final.
Evidence Checklist for Defendants
Arizona-Specific Tips for Defendants
Arizona's $3,500 limit is one of the lowest in the US. If the plaintiff's claim seems inflated or their damages exceed the limit, challenge the amount.
Since lawyers aren't allowed, you and the plaintiff are on equal footing — focus on clear, organized evidence.
You can request a transfer to civil court (Limited Jurisdiction Court) if you prefer a formal trial with full discovery rights.
What Happens If You Lose
Check Arizona's Small Claims Limit
Confirm the maximum claim amount in your state. If the plaintiff is suing for more than the limit, their case may be improperly filed.
