How to Respond to a Lawsuit in Oklahoma: Answer a Summons (2026)

An answer responds to each numbered paragraph of the petition by admitting it, denying it, or stating you lack enough information to admit or deny, and then lists your affirmative defenses. Oklahoma has no statewide mandated answer form, so you type the answer in a caption that conforms to 12 O.S. § 2010, with the court, the parties, and the case number. Common affirmative defenses include the statute of limitations, payment, accord and satisfaction, fraud, contributory negligence, assumption of risk, and waiver.

If you missed your deadline and a judgment by default was rendered under 12 O.S. § 2004(C)(1), you can file a Motion to Vacate Judgment. A standard motion to vacate is filed not later than 30 days under 12 O.S. § 1031.1(B), and the grounds in 12 O.S. § 1031 include unavoidable casualty or misfortune, mistake, neglect, omission, or fraud. Move quickly, because the 30-day window for the standard motion is short and other grounds carry their own time limits.

Sometimes. Parties often agree in writing to extend the answer period, and you can ask the court for more time before your deadline passes. Oklahoma computes the period under 12 O.S. § 2006(A): because the 20-day window is at or above the 11-day threshold, every calendar day counts, with the deadline rolling forward only when the last day falls on a weekend or legal holiday. Get any extension in writing, because the default clock keeps running until the plaintiff agrees, the court grants more time, or you file your answer.

Filing a standard answer in Oklahoma generally carries no fee, though asserting a counterclaim or cross-claim can incur fees. If a fee does apply and you cannot afford it, you can file a Pauper's Affidavit (In Forma Pauperis Affidavit) asking the court to waive it based on your inability to pay. The form is available from the Oklahoma State Courts Network forms library, and submitting it lets you file on time while the court decides eligibility.

Yes. Insufficiency of process and insufficiency of service of process are recognized defenses you can raise by motion or in your answer under 12 O.S. § 2012(B). If service was defective, the time to answer may not have started to run. Raise a service problem promptly rather than ignoring the case, because ignoring the summons still risks a judgment by default under 12 O.S. § 2004(C)(1).

Common affirmative defenses include accord and satisfaction, assumption of risk, contributory negligence, fraud, payment, the statute of limitations, and waiver. To assert your own claims against the plaintiff, you file a counterclaim. Under 12 O.S. § 2013(A), a counterclaim is compulsory if it arises out of the transaction or occurrence that is the subject matter of the plaintiff's claim, so raise it with your answer or you can lose the right to bring it later.

Respond the same way as any civil complaint: file a timely written answer within 20 days that admits or denies each allegation and raises your defenses under 12 O.S. § 2012(A)(1)(a). In debt cases, check the five-year statute of limitations for written contracts under 12 O.S. § 95(A)(1) and whether the collector validated the debt under the federal Fair Debt Collection Practices Act, 15 U.S.C. § 1692g. Attorney review of a debt-collection answer is available as an option. Do not ignore the summons, because silence leads to a default judgment for the full amount claimed.

No. Oklahoma small claims procedure does not require a defensive written answer, because 12 O.S. § 1758 provides that no formal pleading other than the claim and notice is necessary. On a claim up to $10,000, the defendant appears on the date set in the notice rather than filing a paper answer. The only exception is a defendant who asserts a counterclaim or setoff, who must file a verified answer and deliver a copy to the plaintiff not later than 72 hours before the first appearance. Do not let the absence of a general paper deadline fool you: missing the appearance date can result in a default.
