Committee Commentary

Introduction

New Mexico Rule 1-004 has its origins in an act of the first Legislature of the State of New Mexico. 1912 N.M. Laws Ch. 26. When the New Mexico Supreme Court revamped the rules of civil procedure in 1942, 46 N.M. xix-lxxxiv (1942), largely using the 1938 Federal Rules as a model, the provisions of New Mexico Rule 4 continued to reflect some aspects of the service of process provisions of the former New Mexico provisions. Since then piecemeal amendments have occurred but there has been no previous attempt to restructure Rule 1-004 NMRA in light of evolving principles of due process and modern means of communication. The 2004 amendment to Rule 1-004 seeks to accomplish this goal.

Plain-English Summary

Rule 1-004 is the engine for bringing a defendant before the court. It governs how a summons is issued—signed by the clerk, under the court's seal, and in proper form—and how process is served and returned. The plaintiff is responsible for getting service accomplished.

The rule lays out who may serve process and the methods of service. An individual may be served personally, by mail or commercial courier, or through an authorized agent, and, if an attempt at one of those fails, by delivering process to a person over fifteen who lives at the individual's usual place of abode and mailing a copy to the last known address; corporations and other business entities, the State and its political subdivisions, and minors, incompetents, or persons under a fiduciary all have their own prescribed methods. When ordinary methods cannot be accomplished, the court may, on motion, authorize service in another manner reasonably calculated to give notice, and—only on that same kind of court order—service may be made by publication.

Service must be documented: the party who obtained service, or that party's agent, files proof of service (a return) showing how and when it was made. The rule also addresses service in the United States but outside New Mexico and service in a foreign country, so that out-of-state and international defendants can be reached consistent with due process. The committee commentary and case law emphasize that these requirements are designed to give a defendant genuine notice and an opportunity to respond, and that publication is a method of last resort.

Frequently Asked Questions

How is a defendant served in New Mexico?

By serving the summons and complaint in one of the ways Rule 1-004 allows—personal delivery to the individual, service by mail or commercial courier, or service on an authorized agent, and—if an attempt at one of those fails—delivery to a person over fifteen who lives at the individual's usual place of abode, with a copy mailed to the last known address—with separate methods for corporations and other entities, the State and its subdivisions, and minors or incompetent persons.

Who may serve process?

Rule 1-004 specifies who may serve process and makes the plaintiff responsible for accomplishing service; it must then be documented by a return (proof of service) showing how and when service was made.

When is service by publication allowed?

Only on a court order granted under Paragraph J, and generally as a last resort when a defendant cannot be served by the ordinary methods. Where personal methods are not possible, a party may instead ask the court to approve another manner of service reasonably calculated to give notice.

How is an out-of-state or foreign defendant served?

Rule 1-004 provides for service in the United States but outside New Mexico and for service in a foreign country, allowing defendants beyond the state to be served in a manner consistent with the rule and due process.
