Oklahoma Small Claims Affidavit: Forms, Instructions, and Filing Tips

The Small Claims Affidavit and Order is the document that starts your case. In Oklahoma, you do not file a "complaint" or a "petition" on the small claims docket — you file this affidavit, which combines your sworn claim with a judicial order directing the defendant to appear. Getting it right on the first attempt keeps you from making extra trips to the courthouse.

Where to Get the Form

The Small Claims Affidavit and Order is available:

• At the Court Clerk's office in any Oklahoma county — ask the counter staff for the small claims forms
• On the Oklahoma State Courts Network (OSCN) — the standardized form prescribed by the Oklahoma Supreme Court

The form is sometimes referenced as "SC-100," though Oklahoma's official judicial forms are unnumbered. Whatever the label, it is the same document statewide.

You will also need the Military Service Affidavit (Servicemembers Civil Relief Act compliance). This is a separate form certifying whether the defendant is currently on active military duty. It is required for any default judgment.

What the Affidavit Covers

The form has two parts:

The Affidavit (your section):

• Your full legal name and address (plaintiff)
• The defendant's full legal name and address
• The amount you are claiming (up to $10,000)
• A brief factual description of why the defendant owes you money
• The county where the claim arose
• Your signature under oath

The Order (the judge's section):

• The judge fills in the hearing date and time after you file
• It directs the defendant to appear at the scheduled hearing

How to Fill It Out Correctly

Name the defendant precisely. If you are suing a person, use their full legal name — not a nickname, not just a first name. If you are suing a business, look up the exact registered name on the Oklahoma Secretary of State Business Entity Search. A sole proprietor gets sued individually: "John Doe, individually and d/b/a Doe's Repair Services." Suing only the trade name creates an unenforceable judgment.

State your claim in plain language. You do not need legal terminology. "Defendant contracted to repair my roof for $4,500 on [date], accepted a $2,000 deposit, and never performed any work" is clear enough. Include the date, the dollar amount, and what went wrong.

Get the county right. The affidavit asks where the cause of action arose. This determines venue. If you file in the wrong county, the defendant can challenge it and the case gets dismissed.

Sign under oath. You must sign the affidavit before a Court Clerk or a licensed Notary Public. An unsigned or improperly notarized affidavit will be rejected at the counter.

How Many Copies to Bring

Prepare:

• The original for the Court Clerk to file
• Two copies per defendant (one for service, one for the return)
• One copy for yourself as a working record

If you are suing two defendants, that is five copies plus the original. Bring them all at once — the clerk will not make copies for you.

Common Mistakes That Delay Filing

Wrong defendant name. Suing "ABC Plumbing" instead of the LLC's registered name means your judgment may not be enforceable. Always verify through the Secretary of State's database.

Missing the dollar figure. Leaving the claim amount blank or writing "TBD" gets the form kicked back. Calculate your damages before you walk into the clerk's office.

Filing in the wrong county. Venue must be proper under 12 O.S. § 1752b: where the defendant lives, where the dispute happened, or where the property sits for landlord-tenant cases.

Forgetting service fees. The filing fee only covers filing. You need to pay separately for certified mail ($10–$20) or sheriff service ($50) to get the defendant served.

Filing Electronically vs. Paper

OSCN e-filing is available in selected counties, but accounts are limited to Oklahoma attorneys, state agency representatives, and licensed process servers; pro se registrations are not accepted. Self-represented plaintiffs should start a case by filing paper documents with the Court Clerk; ask the clerk whether to file by mail or in person.

If mailing your filing, include the original documents, required copies, a self-addressed stamped envelope, and payment by cashier's check or money order for the exact amount. The case is not officially filed until the clerk stamps it — not when you drop it in the mail.
