Text sizeJump to: (A) (B) (C) (D) (E) (F) (G) (H)

A. When presented. A defendant shall serve his answer within thirty (30) days after the service of the summons and complaint upon him. A party served with a pleading stating a cross-claim against him shall serve an answer thereto within thirty (30) days after the service upon him. The plaintiff shall serve his reply to a counterclaim in the answer within thirty (30) days after service of the answer, or, if a reply is ordered by the court, within thirty (30) days after service of the order, unless the order otherwise directs. The service of a motion permitted under this rule alters these periods of time as follows, unless a different time is fixed by order of the court:
(1) if the court denies the motion or postpones its disposition until the trial on the merits, the responsive pleading shall be served within ten (10) days after the court's action;
(2) if the court grants a motion for a more definite statement, the responsive pleading shall be served within ten (10) days after the service of the more definite statement.
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:
(1) lack of jurisdiction over the subject matter;
(2) lack of jurisdiction over the person;
(3) improper venue;
(4) insufficiency of process;
(5) insufficiency of service of process;
(6) failure to state a claim upon which relief can be granted;
(7) failure to join a party under Rule 1-019 NMRA. 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, he may assert at the trial any defense in law or fact to that claim for relief. If, on a motion asserting the defense in Subparagraph (6) of this paragraph 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 disposed of as provided in Rule 1-056 NMRA, and all parties shall be given reasonable opportunity to present all material made pertinent to such a motion by Rule 1-056 NMRA. Motions shall be prepared and submitted in the manner required by Rule 1-007.1 NMRA.
C. Motion for judgment on the pleadings. After the pleadings are closed but within such time as not to delay the trial, any party may move for judgment on the pleadings. If, on a motion for judgment on the pleadings, matters outside the pleadings are presented to and not excluded by the court, the motion shall be treated as one for summary judgment and disposed of as provided in Rule 1-056 NMRA, and all parties shall be given reasonable opportunity to present all material made pertinent to such a motion by Rule 1-056 NMRA.
D. Preliminary hearings. The defenses specifically enumerated in Subparagraphs
(1) to (7) in Paragraph B of this rule, whether made in a pleading or by motion, and the motion for judgment mentioned in Paragraph C of this rule 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.
E. Motion for more definite statement. If a pleading to which a responsive pleading is permitted is so vague or ambiguous that a party cannot reasonably be required to frame a responsive pleading, he may move for a more definite statement before interposing his responsive pleading. The motion shall point out the defects complained of and the details desired. If the motion is granted and the order of the court is not obeyed within ten (10) days after notice of the order or within such other time as the court may fix, the court may strike the pleading to which the motion was directed or make such order as it deems just.
F. Motion to strike. Upon motion made by a party before responding to a pleading or, if no responsive pleading is permitted by these rules, upon motion made by a party within thirty (30) days after the service of the pleading upon him or upon the court's own initiative at any time, the court may order stricken from any pleading any insufficient defense or any redundant, immaterial, impertinent or scandalous matter.
G. Consolidation of defenses in motion. A party who makes a motion under this rule may join with it any other motions herein provided for and then available to him. If a party makes a motion under this rule but omits therefrom any defense or objection then available to him which this rule permits to be raised by motion, he shall not thereafter make a motion based on the defense or objection so omitted, except a motion as provided in Subparagraph (2) of Paragraph H of this rule on any of the grounds there stated.
H. Waiver or preservation of certain defenses.
(1) A defense of lack of jurisdiction over the person, improper venue, insufficiency of process or insufficiency of service of process is waived:
(a) if omitted from a motion in the circumstances described in Paragraph G of this rule; or
(b) if it is neither made by motion under this rule nor included in a responsive pleading or an amendment thereof permitted by Rule 1-015 NMRA to be made as a matter of course.
(2) A defense of failure to state a claim upon which relief can be granted, a defense of failure to join a party indispensable under Rule 1-019 NMRA and an objection of failure to state a legal defense to a claim may be made in any pleading permitted or ordered under Rule 1-007 NMRA, or by motion for judgment on the pleadings, or at the trial on the merits.
(3) Whenever it appears by suggestions of the parties or otherwise that the court lacks jurisdiction of the subject matter, the court shall dismiss the action.

Rule History

[As amended, effective August 1, 1989.]

Plain-English Summary

This rule runs the early-defense stage of a case. A defendant must answer within thirty days of service, with parallel thirty-day periods for answering a cross-claim or replying to a counterclaim; filing a motion under the rule resets those clocks. Most defenses must go in the responsive pleading, but seven may be raised by motion instead: lack of subject-matter jurisdiction, lack of personal jurisdiction, improper venue, insufficient process, insufficient service, failure to state a claim, and failure to join a party under Rule 1-019. A motion to dismiss for failure to state a claim that brings in outside matter is converted to summary judgment under Rule 1-056.

The rule also allows a motion for judgment on the pleadings after the pleadings close, a motion for a more definite statement when a pleading is too vague to answer, and a motion to strike insufficient or scandalous matter. Defenses must be consolidated: a party who omits an available Rule 1-012 defense from a motion generally cannot raise it later. Personal-jurisdiction, venue, and process defenses are waived if not raised on time, while failure to state a claim, failure to join an indispensable party, and lack of subject-matter jurisdiction are preserved—and the court must dismiss whenever it lacks subject-matter jurisdiction.

Frequently Asked Questions

How long does a defendant have to answer in New Mexico?

Thirty days after service of the summons and complaint. Filing a Rule 1-012 motion changes the timing—if the motion is denied, the responsive pleading is due within ten days after the court acts.

Which defenses can be raised by motion to dismiss?

Lack of subject-matter jurisdiction, lack of personal jurisdiction, improper venue, insufficiency of process, insufficiency of service of process, failure to state a claim, and failure to join a party under Rule 1-019.

Which defenses are waived if not raised early?

Lack of personal jurisdiction, improper venue, and insufficiency of process or service are waived if omitted from a motion or not included in a responsive pleading. Failure to state a claim and lack of subject-matter jurisdiction are not waived this way.
