How does small claims court work in Oklahoma?

Oklahoma has one small claims process statewide. The Small Claims Procedure Act (12 O.S. § 1751 and following) sets one procedure in the District Court. The limit, the sworn affidavit you file, and the base filing fees are the same everywhere. What changes locally is the courthouse, the sheriff's service fee, one optional county add-on on larger claims, and the date the clerk sets.

What forms do I need in Oklahoma?

You start the case with the small claims affidavit and order whose wording is set out in 12 O.S. § 1753. In it you swear that you asked for payment, the defendant refused, and none of the amount has been paid. Ask the District Court clerk for the printed form.

How do I file a small claim in Oklahoma?

Fill out the small claims affidavit set out in 12 O.S. § 1753, file it with the District Court clerk and pay the fee.

  1. Check that your claim is $10,000 or less and that you're allowed to bring it.
  2. Fill out the affidavit (its wording is in 12 O.S. § 1753) and file it with the District Court clerk. Pay the fee.
  3. The clerk sets an appearance date 10 to 60 days from the order and usually serves the defendant by certified mail. You can ask for the sheriff instead.
  4. The defendant must be served at least 7 days before the appearance date. If not, you apply to the clerk for a new order setting a new appearance date, 10 to 60 days out (12 O.S. § 1756).
  5. Go to the hearing with your papers and witnesses. It's informal, and the judge can call witnesses and order documents.
  6. If you win, mail a file-stamped copy of the judgment to every party who appeared and file a certificate of mailing.

Small Claims Coach is built to help you handle your case yourself, without a lawyer — but if your situation is complicated, does not fit our samples, or a deadline is close, you may want to call a lawyer.

Small Claims Coach uses public information to build the Playbook, which coaches you as you organize and present your own case. We are not your lawyer, there is no attorney-client relationship, and we don't want the details of your case.
