Wyoming Small Claims Counterclaim: How to File One as a Defendant

A contractor sues you for $3,000 in unpaid work, but you spent $2,500 hiring someone else to fix what they botched. Or your landlord claims $1,200 in property damage, but they never returned your $1,500 security deposit. You don't just want to defend — you want to assert your own claim.

That's a counterclaim, and Wyoming small claims lets you file one. But the process has specific requirements that catch defendants off guard.

When a Counterclaim Makes Sense

A counterclaim must arise from the same transaction or occurrence as the plaintiff's original claim. If a customer sues you over a defective product you sold them, you can counterclaim for payments they still owe on the same order. You can't use a small claims counterclaim to bring up a completely unrelated debt.

The counterclaim also has to be for money damages — not injunctions, not orders to perform a specific action. Wyoming small claims courts handle monetary disputes up to $6,000.

How to File

Wyoming doesn't publish a standardized counterclaim form for small claims. You need to draft your own written document. It doesn't need to be elaborate, but it must include:

• The same case caption from your court papers (county, Circuit Court, case number, party names)
• A clear statement that you're asserting a counterclaim
• The facts supporting your claim — what happened, when, and why the plaintiff owes you money
• The dollar amount you're seeking

File the written counterclaim with the Circuit Court Clerk before your hearing date. The clerk won't draft it for you or review it for legal sufficiency — they'll accept it for filing and add it to the case docket.

You must also serve a copy on the plaintiff. Hand-deliver it or send it by first-class mail, and attach a signed Certificate of Service to the copy you file with the court. This proves the plaintiff received notice of your counterclaim before the hearing.

The $6,000 Ceiling and District Court Transfer

If your counterclaim is $6,000 or less, the Circuit Court judge hears both the plaintiff's claim and your counterclaim at the same hearing. The judge can rule on both and enter a net judgment — if the plaintiff wins $3,000 on their claim and you win $2,500 on your counterclaim, the net judgment would be $500 in the plaintiff's favor.

If your counterclaim exceeds $6,000, things change substantially. Under Rule 4 of the Wyoming Rules of Civil Procedure for Circuit Courts, a compulsory counterclaim that exceeds the small claims limit requires a transfer to District Court. You'd need to:

1. File a Motion for Transfer to District Court with the Circuit Court Clerk
2. Deposit the $160 District Court docket fee at the time of filing
3. Serve the motion on the plaintiff

The judge will review whether your counterclaim makes a prima facie showing of merit (meaning it's not obviously frivolous). If it does, the entire case — both the plaintiff's claim and your counterclaim — transfers to District Court. That means a more formal proceeding, likely with discovery and possibly a jury trial.

Timing Matters

The most common counterclaim mistake: showing up at the hearing expecting to tell the judge that the plaintiff actually owes you money, without having filed anything beforehand. Judges can (and regularly do) exclude counterclaims that weren't properly noticed in advance. You lose your right to have the counterclaim heard in the same proceeding.

File your counterclaim as soon as you decide to assert one. Give the plaintiff enough time to receive your service copy and prepare — showing up to court with a surprise counterclaim the plaintiff has never seen doesn't go well even if the clerk technically accepted the filing.

What If Your Counterclaim Is Stronger Than Their Claim?

If the judge awards more on your counterclaim than on the plaintiff's original claim, the net judgment goes in your favor. The plaintiff who sued you ends up owing you money. This happens more often than people expect in contractor and security deposit disputes, where the defendant's losses from defective work or withheld deposits regularly exceed what the plaintiff claims they're owed.
