Rules of civil procedure and service of process requirements for New Mexico.
Last updated October 22, 2026
New Mexico's rules for serving a summons and complaint in district court are in the New Mexico Rules of Civil Procedure for the District Courts, mainly Rule 1-004 NMRA. New Mexico has no statewide license for process servers.
The rule has changed. For cases filed on or after December 31, 2025, a court can authorize service by social media, email or text message when the usual methods fail (Supreme Court Order No. S-1-RCR-2023-00009). This page covers the rule as it stands now.

New Mexico process servers
Process-serving software: ServeManager
ServeManager is process-serving software used by agencies across New Mexico. It tracks every attempt with date, time, GPS and photos, and generates affidavits of service from the job.
No. New Mexico doesn't license or register process servers. Any adult over 18 who isn't a party can serve a summons and complaint under Rule 1-004(D)(1). The sheriff can also serve.
For a step-by-step guide to starting out, see Become a Process Server in New Mexico.
New Mexico sets the methods in order. You try personal service first, then move down the list only when the earlier method fails. Whatever method you use must be reasonably calculated to tell the defendant about the case (Rule 1-004(E)(1)).
Hand the summons and complaint to the defendant. If the person refuses to take them, leaving the papers where the person is found counts as valid service.
Send the papers addressed to the defendant by mail or a commercial courier service. The defendant, or someone authorized to receive service for them, must sign a receipt. Service is complete on the date the receipt is signed. An electronic signature counts.
If personal service fails, deliver the papers to someone over 15 who lives at the defendant's usual home, then mail a copy by first-class mail to the defendant's last known mailing address.
If personal service and home service both fail, deliver the papers to the person apparently in charge at the defendant's workplace. Then mail copies by first-class mail to the defendant's last known mailing address and to the workplace.
New Mexico doesn't allow "post and mail" service, where papers are taped to the door. The committee commentary to Rule 1-004 says that method was removed.
For cases filed on or after December 31, 2025, the court can authorize service by social media direct message, email or text. The party asks for it by motion, with an affidavit. They have to show that:
If the court grants the motion, the papers must be sent once a week for three weeks in a row, and a copy must be mailed by first-class mail within 10 days of the first electronic service. Service is complete on the last transmission. The rule spells out what each message must say.
If service can't reasonably be made under the rule, the court can order any method reasonably likely to give notice, including publication. Publication needs a court order. It usually runs once a week for three weeks in a row in a newspaper of general circulation in the county where the case is pending. Service is complete on the date of the last publication. See What is service by publication?
A defendant outside New Mexico can be served using the methods in Rule 1-004. Service in another country follows the Hague Service Convention or other internationally agreed methods where they apply.
A subpoena can be served by the sheriff or by a person over 18 who isn't a party. When the subpoena requires the person to attend, one full day's per diem and mileage must be tendered at the time of service, unless the state issued the subpoena. A private server signs a sworn return. See the court's subpoena form and use notes (Form 4-505), used with Rule 1-045 NMRA.
The party who arranged service must promptly file proof of service (Rule 1-004(L)):
Rule 1-011 NMRA also allows an unsworn statement under penalty of perjury in place of a notarized affidavit in many filings. Failing to file proof doesn't make the service itself invalid.
