New Mexico ranks its ways to serve. Under Rule 1-004(F), an individual is served in hand or by mail or courier against a signed receipt first; only after that try may the papers go to a resident over 15 at the defendant’s home, with a copy mailed first class, and only after that to the person in charge at work. Served 123 LLC arranges New Mexico service in all 33 counties through local process servers who are over 18 and not a party, with up to three attempts per address and the server’s sworn return on Form 4-206.

New Mexico return: the sworn return on Form 4-206, stating the server is over 18 and not a party and checking the Rule 1-004 method used; a sheriff or deputy proves service by certificate instead (Rule 1-004(L)).
Rule 1-004(C)(2) sets no number of days. Service of process is made with reasonable diligence, and the original summons with proof of service is filed with the court under Paragraph L.
The committee commentary contrasts this with Federal Rule 4(m), which has a specific time limit, and says reasonable diligence reflects the standard in New Mexico case law, citing Romero v. Bachicha, 2001-NMCA-048.
The Supreme Court of New Mexico writes the district court civil rules. Rule 1-004 NMRA governs service of process, Rule 1-045 subpoenas, Rule 1-006 counting time, and Forms 4-206 and 4-505 carry the returns a server signs.
Process shall be served in a manner reasonably calculated, under all the circumstances, to apprise the defendant of the existence and pendency of the action and to afford a reasonable opportunity to appear and defend.

General information, not legal advice. The rule controls.
Rule 1-004(F) is a ladder, with some methods opening only after an earlier one has been tried, and Served 123 takes a case up every rung on one order: in hand, the abode, the workplace, companies and the Secretary of State, court-ordered publication, signed-receipt mail, service outside New Mexico and electronic service by order. A sheriff serving a writ and a defendant’s waiver are the routes it leaves aside.
Every route above, one order.

A New Mexico sheriff or deputy proves service by certificate; anyone else proves it by affidavit. The return on the Supreme Court’s summons form, Form 4-206, is the server’s sworn statement; under Rule 1-011(B), a statement dated, signed and affirmed under penalty of perjury under New Mexico law has the same effect in court as one sworn before a notary.
Unless the court orders otherwise, the return is not filed before the summons and complaint are served, and a failure to make proof does not affect the validity of service.

New Mexico asks for service with reasonable diligence rather than within a set number of days (Rule 1-004(C)(2)), so timing usually turns on your own schedule or a court date. Preferred, Next-Day and Same-Day set when the first attempt is made; a first attempt is not service.

No. It requires service with reasonable diligence and has the original summons, with proof of service, filed with the court under Paragraph L. The committee commentary contrasts this with Federal Rule 4(m), which has a specific time limit, and says reasonable diligence reflects the standard in New Mexico case law, citing Romero v. Bachicha, 2001-NMCA-048. A defendant may raise insufficiency of service of process by motion under Rule 1-012(B)(5), and Rule 1-041(B) lets a defendant move to dismiss for the plaintiff’s failure to prosecute or to comply with the rules. If a limitation period is close, ask counsel.
Copy LinkOnly after the plaintiff has tried one of the Rule 1-004(F)(1) methods, in-hand delivery or mail or courier against a signed receipt, and the defendant has not signed for or accepted service. One of the two is enough, the commentary says. The copy then goes to a person over 15 who lives at the defendant’s usual place of abode, and a copy is also mailed first class to the defendant’s last known mailing address. Posting the papers at the abode, allowed under the former rule, was dropped in 2004.
Copy LinkIf service is not accomplished in hand, by mail or courier, or at the abode, the papers may be delivered to the person apparently in charge at the defendant’s actual place of business or employment. The summons and complaint are also mailed first class to the defendant at the last known mailing address and at that workplace. The commentary calls this a hierarchy: some methods cannot be used until others have been tried without success.
Copy LinkThe envelope is addressed to the named defendant, and service happens only when the defendant, or a person authorized by appointment, by law or by Rule 1-004 to accept service, signs a receipt for it. It is complete on the date the receipt is signed, and an electronic signature counts. The mailing need not go to the home address. Proof is a certificate of service with the delivery date and a copy of the signature receipt.
Copy LinkA domestic or foreign corporation, an LLC or an equivalent business entity is served through an officer, a managing or general agent, or another agent authorized by appointment, by law or by the rule; when the agent is a statutory one and the statute requires it, a copy is also mailed to the defendant. A partnership is served through any general partner. If the person refuses, tendering the papers is valid service, and if none of those people is available, the papers may be delivered to the person in charge at the principal office or place of business during regular business hours. Mail or courier against a signed receipt is also allowed. By statute, the registered agent a corporation appoints is its agent for any process (NMSA 1978 § 53-11-14).
Copy LinkUnder Rule 1-004(F)(4), on a motion without notice backed by an affidavit or other sworn testimony that in-hand, abode and workplace service cannot reasonably be made. The plaintiff shows a diligent attempt at those three methods, or that they are impractical, and that the defendant owns the account, address or number and has sent transmissions from it within 30 days of the motion. The order requires a first class mailing within 10 days of the first electronic service and transmissions once each week for three consecutive weeks; service is complete on the last one.
Copy LinkThe state is served on the governor and the attorney general; a state agency on its head and the attorney general; a state officer or employee on that person and the attorney general. Papers for the governor, the attorney general or an agency may go to the chief operating officer or the state officer’s receptionist. A county is served on the county clerk, a municipality on its city, town or village clerk, and a school district on its superintendent. In garnishment actions, writs of garnishment go to the Department of Finance and Administration, the attorney general and the head of the branch, agency, bureau, department, commission or institution, and a copy is delivered or served on the defendant employee in the manner and priority of Paragraph F. Mail or courier against a signed receipt also works for each of them.
Copy LinkRule 1-045(B)(6) has it issued under Rule 1-045.1 after a miscellaneous proceeding is filed in the judicial district where the subpoena is to be served; Rule 1-045.1(B)(1) has the foreign subpoena submitted to the clerk of the district court where the discovery is sought to be conducted in New Mexico. Once that proceeding is docketed, the clerk issues a subpoena incorporating the foreign subpoena’s terms, and it is served under Rule 1-045, by any non-party not less than 18. When attendance is commanded, one full day’s per diem under NMSA 1978 § 10-8-4(A) and mileage under § 10-8-4(D) are tendered with it; the per diem is not prorated, a full day’s expenses are paid before each day of attendance when it runs more than one day, and fees and mileage need not be tendered when the subpoena issues on behalf of the state or one of its officers or agencies. Witnesses get no fee for services under NMSA 1978 § 38-6-4(A), only that per diem and mileage: the per diem a nonsalaried public officer receives for a board or committee meeting, and mileage of up to the IRS standard mileage rate set January 1 of the previous year for each mile in a privately owned vehicle.
Copy LinkThe server states under oath being over 18 and not a party, the county and date of service, and checks the Rule 1-004 method used: to the defendant, by mail or courier, to a resident over 15 at the abode with a mailing, to the person in charge at work with mailings, to an authorized agent, to a parent, guardian or conservator of a minor or incompetent person, or to the titled person for a company, association, land grant board or public body. Unless the court orders otherwise, the return is not filed before service, and failure to make proof does not affect the validity of service.
Copy LinkYes. When the court’s jurisdiction does not depend on service inside New Mexico, as with long-arm jurisdiction under NMSA 1978 § 38-1-16, service outside the state follows Rule 1-004 in the same manner and priority. Section 38-1-16 reaches, among others, a person who transacts business or commits a tortious act in New Mexico, but only for claims arising from that act, and the summons may be served on that person personally outside the state with the same effect as service inside it. Abroad, Rule 1-004(N) allows any internationally agreed means reasonably calculated to give notice, such as the Hague Service Convention. Where there is none, or the agreement allows other means, and provided the method is reasonably calculated to give notice, it also allows the foreign country’s own method, a letter rogatory or letter of request, or the Rule 1-004(F), (G) or (J) methods in the same manner and priority unless the law of the United States or that country forbids them.
