How to File a Counterclaim in Oklahoma Small Claims Court

Someone sued you in Oklahoma small claims court, but the story isn't one-sided. Maybe the contractor who's claiming unpaid invoices actually left your kitchen half-demolished. Maybe the tenant suing for their deposit back caused damage that cost more to repair than the deposit covered. You don't just want to defend — you want to countersue.

Oklahoma lets you do that. But the deadline is brutally tight.

The 72-Hour Rule

Under 12 O.S. § 1758, file a verified answer with the court clerk and deliver a copy to the plaintiff in person at least 72 hours before the scheduled first appearance. Pay the $20 counterclaim filing fee under 28 O.S. § 152.1(A)(2).

Those 72 hours exclude weekends and state holidays under 12 O.S. § 2006 (the exclusion rule applies because the period is less than 11 days). So if your first appearance is Monday morning at 9:00 a.m., your real deadline is the previous Wednesday by 9:00 a.m. — not Friday, because Saturday and Sunday don't count.

Miss this window and the court won't hear your counterclaim at that hearing. You'd need to either ask the judge for a continuance (no guarantee) or file your own separate small claims action against the plaintiff later.

What the Verified Counterclaim Looks Like

Oklahoma requires a "verified answer" for counterclaims — meaning your document must be sworn under oath. The statutory form under 12 O.S. § 1758 requires:

• The county and district court name
• The case number from the plaintiff's original filing
• Both parties' names exactly as they appear on the original affidavit
• A sworn statement that the plaintiff is indebted to you, with the specific dollar amount and the reason why
• Your signature, notarized or sworn before a court clerk or judge

Most county clerk offices have a blank counterclaim form you can fill out at the window. Call ahead to confirm — some rural counties (Garfield, McCurtain, Creek) only process filings during limited hours, and you cannot afford a wasted trip this close to a deadline.

Filing Fees

The counterclaim filing fee is $20 under 28 O.S. § 152.1(A)(2). If you can't afford the fee, you can file an Affidavit in Forma Pauperis under 28 O.S. § 152 to request a fee waiver — but get that paperwork in before your 72-hour deadline, not after.

Serving the Plaintiff

Filing with the clerk isn't enough. Section 1758 requires you to deliver a copy to the plaintiff in person at least 72 hours before the first appearance; the original claim's service methods do not replace this requirement.

Deliver the copy in person and keep proof of when and how it was delivered, such as a signed acknowledgment. If the plaintiff claims they never received it, you need documentation.

What If Your Counterclaim Exceeds $10,000?

Oklahoma's small claims docket caps at $10,000 exclusive of fees and costs (12 O.S. § 1751). If your counterclaim exceeds that ceiling, the entire case — the original claim and your counterclaim — gets transferred to the regular civil docket under 12 O.S. § 1758 and § 1759. Regular civil rules then apply, including formal written pleadings, discovery, and potentially a longer timeline.

This isn't necessarily bad news if you have a strong case worth more than $10,000, but it does change the complexity and cost of the proceedings.

At the Hearing

When the judge calls your case, both the original claim and the counterclaim are heard together. The plaintiff presents their case first, then you present both your defense and your counterclaim. Bring three copies of everything — your counterclaim filing, your proof of service, and every piece of supporting evidence.

The judge can rule in favor of either party on either claim. You might win your counterclaim but lose on the original claim, or vice versa. If both sides owe each other money, the judge typically offsets the amounts and enters a single net judgment.

Don't Wait Until the Last Day

The 72-hour deadline is a hard cutoff, not a suggestion. Court clerks in metropolitan counties like Oklahoma and Tulsa process filings throughout business hours, but rural county offices may close early or operate on limited schedules. Build in at least one extra business day as a buffer.
