Chapter 39: Oklahoma Pleading Code · Last amended November 1, 2004 · Last verified August 3, 2026
In one sentenceSection 2012 is Oklahoma's motion-to-dismiss statute, setting answer deadlines, listing ten defenses, including failure to state a claim, that may be raised by motion before answering, and governing waiver, consolidation, and what happens when a dismissed claim isn't timely amended.
1.Unless a different time is prescribed by law, a defendant shall serve an answer:
a.within twenty (20) days after the service of the summons and petition upon the defendant,
b.within twenty (20) days after the service of the summons and petition upon the defendant, or within the last day for answering if applicable; provided, a defendant may file a reservation of time which shall extend the time to respond twenty (20) days from the last date for answering. The filing of such a reservation of time waives defenses of paragraphs 2, 3, 4, 5, 6, and 9 of subsection B of this section.
2.A party served with a pleading stating a cross-claim against that party shall serve an answer thereto within twenty (20) days after the service upon the party.
3.The plaintiff shall serve a reply to a counterclaim in the answer within twenty (20) days after service of the answer or, if a reply is ordered by the court, within twenty (20) days after service of the order, unless the order otherwise directs.
4.The party requesting a summons to be issued or filing a counter-claim or cross-claim may elect to have the answer served within thirty-five (35) days in lieu of the twenty (20) days set forth in this section.
5.The service of a motion permitted under this section or a motion for summary judgment alters these periods of time as follows: if the court denies the motion or postpones its disposition until the trial on the merits, the responsive pleading shall be served within twenty (20) days after notice of the court's action, unless a different time is fixed by order of the court.
B.HOW PRESENTED. Every defense, in law or fact, to a claim for relief in any pleading, whether a claim, counterclaim, cross-claim, or third-party claim, shall be asserted in the responsive pleading thereto if one is required, except that the following defenses may at the option of the pleader be made by motion:
10.Lack of capacity of a party to sue. A motion making any of these defenses shall be made before pleading if a further pleading is permitted. No defense or objection is waived by being joined with one or more other defenses or objections in a responsive pleading or motion. If a pleading sets forth a claim for relief to which the adverse party is not required to serve a responsive pleading, the adverse party may assert at the trial any defense in law or fact to that claim for relief. If, on a motion asserting the defense numbered 6 of this subsection to dismiss for failure of the pleading to state a claim upon which relief can be granted, matters outside the pleading are presented to and not excluded by the court, the motion shall be treated as one for summary judgment and all parties shall be given reasonable opportunity to present all material made pertinent to the motion by the rules for summary judgment. A motion to dismiss for failure to state a claim upon which relief can be granted shall separately state each omission or defect in the petition, and a motion that does not specify such defects or omissions shall be denied without a hearing and the defendant shall answer within twenty (20) days after notice of the court's action.
C.PRELIMINARY HEARINGS. The defenses specifically enumerated in paragraphs 1 through 10 of subsection B of this section, whether made in a pleading or by motion, and the motion to strike mentioned in subsection D of this section shall be heard and determined before trial on application of any party, unless the court orders that the hearing and determination thereof be deferred until the trial. If the court determines that venue is proper, the action shall not be dismissed for improper venue as a result of the jury's verdict or the subsequent ruling of the court on a demurrer to the evidence or a motion for a directed verdict.
D.MOTION TO STRIKE. Upon motion made by a party before responding to a pleading or, if no responsive pleading is permitted by this act, upon motion made by a party within twenty (20) days after the service of the pleading upon the party or upon the court's own initiative at any time, the court may order stricken from any pleading any insufficient defense. If, on a motion to strike an insufficient defense, matters outside the pleadings are presented to and not excluded by the court, the motion shall be treated as one for partial summary judgment and all parties shall be given reasonable opportunity to present all materials made pertinent to the motion by the rules for summary judgment.
E.CONSOLIDATION OF DEFENSES IN MOTION. A party who makes a motion under this section may join with it any other motions herein provided for and then available to the party. If a party makes a motion under this section but omits therefrom any defense or objection then available to the party which this section permits to be raised by motion, the party shall not thereafter make a motion based on the defense or objection so omitted, except a motion as provided in paragraph 2 of subsection F of this section on the grounds there stated. The court in its discretion may permit a party to amend a motion by stating additional defenses or objections if an amendment is sought at least five (5) days before the hearing on the motion.
1.A defense of lack of jurisdiction over the person, improper venue, insufficiency of process, insufficiency of service of process, failure to state a claim upon which relief can be granted, or lack of capacity of a party to be sued is waived:
a.if omitted from a motion that raises any of the defenses or objections which this section permits to be raised by motion, or
b.if it is not made by motion and it is not included in a responsive pleading or an amendment thereof permitted by subsection A of Section 2015 of this title to be made as a matter of course. A motion to strike an insufficient defense is waived if not raised as in subsection D of this section.
2.A defense of failure to join a party indispensable under Section 2019 of this title may be made in any pleading permitted or ordered under subsection A of Section 2007 of this title or at the trial on the merits. A defense of another action pending between the same parties for the same claim or a defense of lack of capacity of a party to sue may be made in any pleading permitted or ordered pursuant to the provisions of subsection A of Section 2007 of this title or at the pretrial conference.
3.Whenever it appears by suggestion of the parties or otherwise that the court lacks jurisdiction of the subject matter, the court shall dismiss the action.
4.A waiver of the defense in paragraph 6 of subsection B of this section does not preclude a later contention that a party is not entitled to any relief as a matter of law, either by motion for summary judgment, or by demurrer or motion at or after trial.
G.FINAL DISMISSAL ON FAILURE TO AMEND. On granting a motion to dismiss a claim for relief, the court shall grant leave to amend if the defect can be remedied and shall specify the time within which an amended pleading shall be filed. If the amended pleading is not filed within the time allowed, final judgment of dismissal with prejudice shall be entered on motion except in cases of excusable neglect. In such cases amendment shall be made by the party in default within a time specified by the court for filing an amended pleading. Within the time allowed by the court for filing an amended pleading, a plaintiff may voluntarily dismiss the action without prejudice.

Plain-English Summary
This section is Oklahoma's version of FRCP 12, covering both timing and substance. A defendant generally must answer within twenty days of service, or thirty-five if the plaintiff elects that option, with an automatic twenty-day extension available through a reservation of time, though filing one waives several of the motion-based defenses listed below. Instead of answering right away, a party may move to dismiss, or otherwise raise, ten specific defenses: lack of subject-matter or personal jurisdiction, improper venue, insufficiency of process or of service, failure to state a claim, failure to join a necessary party, another pending action between the same parties, and lack of capacity to sue or be sued.
If a motion asserting failure to state a claim brings in matters outside the pleadings that the court doesn't exclude, the motion converts into one for summary judgment, and both sides get a reasonable chance to present evidence under the summary-judgment rules. A motion to dismiss for failure to state a claim must separately identify each defect in the petition; one that doesn't will be denied without a hearing, and the defendant then has twenty days to answer.
Several of these defenses -- personal jurisdiction, venue, process, service, failure to state a claim, and lack of capacity to be sued -- are waived if a party omits them from an initial motion or fails to raise them in the first responsive pleading. Others, like failure to join an indispensable party or lack of capacity to sue, survive until any pleading permitted under Section 2007 or even the pretrial conference, and a challenge to subject-matter jurisdiction can be raised, or the court can raise it on its own, at any time. When a court grants a motion to dismiss, it must give leave to amend if the defect is fixable and set a deadline; miss that deadline without excusable neglect, and the dismissal becomes final and with prejudice on motion.
Frequently Asked Questions
How long does a defendant have to answer a petition in Oklahoma?
Twenty days after service of the summons and petition, or thirty-five days if the party requesting the summons elects that option, under subsection A, with an additional twenty-day extension available by filing a reservation of time, which waives several motion-based defenses.
What defenses can be raised by motion instead of in the answer?
Ten of them, listed in subsection B, including lack of subject-matter or personal jurisdiction, improper venue, insufficient process or service, failure to state a claim, failure to join a necessary party, another action pending, and lack of capacity to sue or be sued.
What happens if a motion to dismiss relies on evidence outside the petition?
If the court doesn't exclude that outside material, subsection B converts the motion into one for summary judgment, with both sides given a reasonable opportunity to present evidence.
Can a defendant lose the right to challenge personal jurisdiction or venue?
Yes -- subsection F waives those defenses, along with insufficient process, insufficient service, failure to state a claim, and lack of capacity to be sued, if they're left out of an initial motion or the first responsive pleading.
What happens if a dismissed claim isn't amended in time?
Subsection G makes the dismissal final and with prejudice on motion, unless the failure to amend was the result of excusable neglect.
