Text sizeJump to: (A) (B)

A. Signing of pleadings, motions, and other papers; sanctions. Every pleading, motion, and other paper of a party represented by an attorney, shall be signed by at least one attorney of record in the attorney’s individual name, whose address and telephone number shall be stated. A party who is not represented by an attorney shall sign the party’s pleading, motion, or other paper and state the party’s address and telephone number. The signature of an attorney or party constitutes a certificate by the signer that the signer has read the pleading, motion, or other paper; that to the best of the signer’s knowledge, information, and belief there is good ground to support it; and that it is not interposed for delay. If a pleading, motion, or other paper is signed with intent to defeat the purpose of this rule, it may be stricken as sham and false and the action may proceed as though the pleading or other paper had not been served. If a pleading, motion, or other paper is not signed, it shall be stricken unless it is signed promptly after the omission is called to the attention of the pleader or movant. For a willful violation of this rule an attorney or party may be subjected to appropriate disciplinary or other action. Similar action may be taken if scandalous or indecent matter is inserted. A “signature” means an original signature, a copy of an original signature, a computer generated signature, or any other signature otherwise authorized by law.
B. Unsworn affirmations under penalty of perjury. Except as provided in Rule 1-120 NMRA, any written statement in a pleading, paper, or other document that is not notarized shall have the same effect in a court proceeding as a notarized written statement, provided that the statement includes the following:
(1) the date that the statement was given;
(2) the signature of the person who gave the statement; and
(3) a written affirmation under penalty of perjury under the laws of the State of New Mexico that the statement is true and correct.

Committee Commentary

New Mexico has enacted an Electronic Authentication Documentation Act which provides for the Secretary of State to register electronic signatures using the public key technology. See Section 14-15-4 NMSA 1978.

Committee commentary for 2008 and 2014 amendments. — Rule 1-011 NMRA was amended in 2008 to permit self-affirmation in lieu of notarization of any written sworn statement required or permitted under the Rules of Civil Procedure for the District Courts. The 2008 amendment, however, did not permit self-affirmation of a statement that must be sworn under statute. See, e.g., NMSA 1978, § 40-4-6 (providing that a petition for dissolution of marriage “must be verified by the affidavit of the petitioner”). The 2014 amendment removed that limitation. See Miller & Assocs., Inc. v. Rainwater, 1985-NMSC-001, ¶¶ 6-8, 102 N.M. 170, 692 P.2d 1390 (holding that NMSA 1978, Section 38-7-1, which requires the denial of an account to be “under oath, in writing, and filed as a part of the pleadings before trial,” is “merely a rule of procedure” and therefore is unconstitutional under Ammerman v. Hubbard Broadcasting, Inc., 1976-NMSC-031, 89 N.M. 307, 551 P.2d 1354). Thus, notarization is no longer required for any written statement in a court proceeding, including a declaration, verification, certificate, oath, affirmation, acknowledgment, or affidavit, as long as the statement is affirmed under penalty of perjury in accordance with Paragraph B of this rule. Accord NMSA 1978, § 30-25-1(A) (2009) (“Perjury consists of making a false statement under oath, affirmation or penalty of perjury, material to the issue or matter involved in the course of any judicial, administrative, legislative or other official proceeding or matter, knowing such statement to be untrue.” (emphasis added)).

Plain-English Summary

This rule puts a name and a promise behind every court filing. A represented party’s pleadings, motions, and papers must be signed by at least one attorney of record, in that attorney’s own name, with an address and phone number; a self-represented party signs and gives the same information. The signature certifies that the signer read the paper, believes there is good ground to support it, and is not filing it for delay. A paper signed to defeat the rule may be stricken as sham, an unsigned paper is stricken unless promptly signed once the omission is noticed, and a willful violation—or inserting scandalous matter—can draw discipline.

The second half lets an unsworn affirmation stand in for notarization. Except as Rule 1-120 provides, a written statement that is not notarized has the same effect as a notarized one if it shows the date, the signer’s signature, and an affirmation under penalty of perjury under New Mexico law that the statement is true. As the committee commentary explains, after the 2008 and 2014 amendments notarization is no longer required for any written statement in a court proceeding, though using a notary remains an option.
