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.
Scope of Rule; Rule 1-004(A)(1)
Generally, statutory provisions are inapplicable if those provisions purport to set procedural requirements that contradict the Rules of Civil Procedure. Ammerman v. Hubbard Broadcasting, Inc., 89 N.M. 307, 551 P.2d 1354 (1976). Rule 1-001(A) creates an exception to Ammerman, extending deference to the procedural requirements set by the legislature in special proceedings that would not exist but for creation by the legislature. The root of the Rule 1-001(A) exception for special statutory proceedings is the provision in the New Mexico Constitution giving the district courts "such jurisdiction of special cases and proceedings as may be conferred by law." N.M. Const., art. VI, § 13. The Rule 1-001(A) exception for special statutory proceedings is a prudential exception generally applied to statutory provisions that affect procedural rules even though the statutory provisions do not deal with jurisdictional matters. The Supreme Court, though, has ultimate authority over all procedural rules and thus can supersede by rule a non-jurisdictional statutory procedure in special statutory and summary proceedings. Rule 1-004(A)(1) is an exercise of that authority.
Rule 1-004 was amended in 2005 to bring New Mexico’s service of process procedure in line with evolving principles of due process. Questions have arisen whether the 2005 amendments to Rule 1-004 apply in special statutory proceedings where the statute provides lesser notice requirements than Rule 1-004. See, e.g., NMSA 1978, § 45-1-401 (provision of the Probate Code permitting notice by publication without court order and only requiring two weekly notices); and NMSA 1978, § 42A-1-14 (Eminent Domain Code provision providing for service by mail and by publication in manners inconsistent with Rule 1-004).
The committee is of the view that, since Rule 1-004 requirements derive from constitutional due process requirements, new subparagraph (A)(1) clarifies that the requirements of Rule 1-004 must be satisfied to validly serve a person or give them notice of the pendency of special statutory proceedings as well as civil actions.
Summons; issuance; Rule 1-004(A)(2)
"Plaintiff" includes "Petitioner" and "Defendant" includes "Respondent". See Rule 1-001(B)(1) and (2). The "Complaint" referred to in Rule 1-004(A) includes "Petition". See Rule 1-001(B)(3).
Rule 1-004(A) previously provided that the clerk shall "forthwith" issue a summons upon filing of the complaint. The word is omitted from the 2004 Amendment because it was redundant; the rule already provides that the clerk "shall" issue a summons "[u]pon the filing of the complaint".
Rule 1-004(A) previously provided that separate or additional summons may be issued "against any defendants". Because it may be necessary to serve a summons on persons not formally denominated as a defendant, for example, upon a third-party defendant under Rule 1-014 NMRA, the rule has been modified to eliminate the implication that additional summonses may issue only against defendants.
The committee considered but did not provide that a person other than the plaintiff or petitioner could request issuance of a summons.
Summons; execution; form; Rule 1-004(B)
Rule 1-011 NMRA requires that all "paper" shall contain the telephone number of the attorney or the pro-se litigant. Except for the provision requiring that the summons include the telephone number as well as the name and address of the plaintiff's attorney or the pro se plaintiff, only technical changes have been made in this section. A form summons approved by the New Mexico Supreme Court may be found at 4-206 NMRA.
Service of Process; return; Rule 1-004(C)
"Process" is defined in Rule 1-001(B)(3) NMRA.
Sometimes a summons is not served in conjunction with the pleading instituting an action. For example, writs, warrants and mandates are not accompanied by a summons. See Rule 1-001(B)(3)(c) and (d) NMRA. Rule 1-004(C)(1) acknowledges that service of process sometimes does not include the service of a summons.
Rule 1-004(C)(2) is new. Unlike Federal Rule 4(m), which contains a specific time limit within which service of the summons and complaint ordinarily must be made, Rule 1-004(C)(2) provides only that service shall be made "with reasonable diligence". This reflects the standard established in New Mexico case law. E.g., Romero v. Bachicha, 2001 NMCA-048 Par. 23-25, 130 N.M. 610, 616, 28 P.3d 1151, 1157.
Process; by whom served; Rule 1-004(D)
Rule 1-004(D) formerly provided that process could be served by a sheriff of the county where the defendant could be found, or by any person over the age of eighteen and not a party to the action. Because the latter category necessarily includes the sheriff of a county, the reference to service by the sheriff has been omitted.
Rule 1-004(D)(2) carries over, unchanged, former Rule 1-004(D)(2).
Rule 1-004(D)(3) is new. It provides a means for determining who shall serve process when the process is a writ other than those mentioned in Rule 1-004(D)(2).
Process; how served; generally; Rule 1-004(E)
Rule 1-004(E)(1) makes explicit in the rule the general test for constitutionally-adequate service of process established in Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306, 314 (1950) ("An elementary and fundamental requirement of due process in any proceeding which is to be accorded finality is notice reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections".).
Rule 1-004(E)(2) accepts the premise that matters of procedure are for the judiciary to determine but that legislation affecting procedure is valid unless and until contradicted by a rule of procedure promulgated by the Supreme Court. Rule 1-091 NMRA; Section 38-1-2 NMSA 1978. The section thus provides that service of process shall be made in accordance with Rule 1-004 NMRA, or in accordance with applicable statutes but shall not be accomplished by a means authorized by a statute that conflicts with Rule 1-004. Rule 1-004(E)(3) provides a much-simplified method of service by mail. It is no longer necessary that the defendant open the mailed packet containing the summons and complaint and then voluntarily choose to accept service by returning a signed Receipt of Service of Summons and Complaint as formerly was required. Instead, service is accomplished when the summons and complaint are mailed to the named defendant in a manner that calls for the recipient to sign a receipt upon receiving the envelope containing the summons and complaint and the defendant-recipient or a person authorized by appointment or by law to accept service of process on behalf of the defendant signs the receipt upon receiving the mailed envelope or package.
Service by mail need not be at the home address or usual place of abode of the defendant. Service is complete when the receipt is signed.
This section also provides the same mechanism for service of the summons and complaint when a "commercial courier service" is utilized instead of the mails. The phrase, though not entirely self-explanatory, has been used in this context by other states without apparent problems. See, e.g., Kansas Rules of Civil Procedure, KSA 60-303 (c)(1); Utah Rules of Civil Procedure 4(d)(2)(A)and (B). The Advisory Committee Note to Utah Rule 4 provides that "[t]he term ‘commercial courier service’ refers to businesses that provide for the delivery of documents. Examples of ‘commercial courier service’ include Federal Express and United Parcel Service". The committee endorses the definition provided in the Utah Advisory Committee Note.
In this context, "signs" and "signed" is equivalent to "signature" which "means an original signature, a copy of an original signature, a computer generated signature or any other signature otherwise authorized by law". Rule 1-011 NMRA.
Process; personal service upon an individual; Rule 1-004(F)
In General. The 2004 Amendment makes substantial changes in Rule 1-004(F). The "post and mail" method found in the former rule has been eliminated. A provision for service at the place of work of the defendant has been added. The provision for mail service has been simplified and the rule now authorizes the use of commercial courier services as well as mail for service of process. A hierarchy of methods of service has been established. In some cases, a listed method of service cannot be used until other methods of service are attempted unsuccessfully.
Rule 1-004(F)(1)(a). This subparagraph remains the same as in the former Rule.
Rule 1-004(F)(1)(b). This subparagraph authorizes service by mail or commercial courier service as provided in Rule 1-004(E)(3).
Rule 1-004(F)(2). The means of service provided in this section may only be used if there first was an attempt to serve process "by either of the methods of service provided by Subparagraph (1) of this paragraph". This means that the person serving process need only attempt one of the two methods-personal service or mail/commercial courier service before using the alternative provided in this subparagraph.
This provision allows service to a person over the age of 15 who resides at the usual place of abode of the defendant. This is the same procedure as that formerly provided in Rule 1-004(F)(1) before the 2004 amendment. The former rule, however, required only delivery of the summons and complaint to such a person for service to be valid. The 2004 amendment provides that service is not accomplished until, in addition, the person serving the summons and complaint mails a copy of the summons and complaint to the defendant at the defendant's last known mailing address. This provision allows service to a person over the age of 15 who resides at the usual place of abode of the defendant. This is the same procedure as that formerly provided in Rule 1-004(F)(1) before the 2004 amendment. The former rule, however, required only delivery of the summons and complaint to such a person for service to be valid. The 2004 amendment provides that service is not accomplished until, in addition, the person serving the summons and complaint mails a copy of the summons and complaint to the defendant at the defendant's last known mailing address. This mailing address will often, but not always, be the usual place of abode of the defendant. The cost of mailing is minimal and increases the likelihood that the defendant will get actual, timely notice of the institution of the action.
Rule 1-004(F)(1) formerly provided that if no qualified person was at the usual place of abode to accept service of process, service could be made by posting process at the abode and then mailing a copy of the process to the last known mailing address. This alternative method of service has been omitted in the 2004 amendment.
Rule 1-004(F)(3) is new. It may be used only when service of process has been attempted, unsuccessfully, in accordance with Rule 1-004(F)(1) and Rule 1-004(F)(2). Rule 1-004(F)(3) provides that service may be made by delivering a copy of the summons and complaint to the person apparently in charge of the actual place of business of the defendant and mailing a copy of the summons and complaint to the defendant both at the defendant's last known mailing address and also the defendant's actual place of business.
Colorado, R.C.P. 4(e)(2), Oregon, R.C.P. 7(d)(2)(c) and New York, N.Y. CPLR Sec. 308(2), also provide for work place service of process. The Fair Debt and Collection Practices Act, 15 U.S.C. Sec. 1692 ff, contains a provision allowing service of process at the workplace of the defendant by "any person while serving or attempting to serve legal process in connection with judicial enforcement of any debt". 15 U.S.C. Sec. 1692(a)(6)(D).
Process; Service on corporation or other business entity; Rule 1-004(G)
In addition to providing for service of process on corporations, Rule 1-004(G)(1) now includes limited liability companies as well as any "equivalent business entity" to a corporation or limited liability company. Courts should construe that phrase to assure that Rule 1-004 provides appropriate guidance about proper service of process upon legislatively-created variations on the traditional corporation.
The substance of the former provisions concerning service of process on partnerships and unincorporated associations have been carried over unchanged in Rule 1-004(G)(1)(b) and (c) of the 2004 amendment.
Process; Service upon state and political subdivisions; Rule 1-004(H)
Subparagraphs (a), (b), (c), (d) and (e) or Rule 1-004(H)(1) are substantively the same as former Rule 1-004(F) (3) and (4). They are derived from and do not vary materially from Section 38-1-7 NMSA 1978.
Subparagraphs (f), (g) and (i) are substantively the same as former Rule 1-004(F)(4), (5) and (6).
Subparagraph (h), dealing with service of process on a school district or school board is new. Former Rule 1-004 provided no guidance on the proper manner of service to such entities.
Rule 1-004(H)(2) allows service of process to the persons designated in Rule 1-004(H)(1) by means of mail or commercial courier service as provided in Rule 1-004(E)(3).
Process; Service upon minor, incapacitated person or conservator; Rule 1-004(I)
Subparagraph 1; Service on minors. The provision for service on a guardian or conservator is carried over from former Rule 1-004(F)(7) except that such service now may be in any manner provided in Paragraph F, G, or L as appropriate, rather than, as formerly, only "by delivering a copy -- to the conservator or guardian".
The provision for service upon person or persons having legal authority over a minor who does not have a guardian or conservator is new as is the provision requiring resort to the court to formulate a method of service where the minor has no guardian, conservator or person with legal authority over the minor.
Subparagraph 2; Service on incompetent persons. Rule 1-004(F)(7) formerly used the phrase "incapacitated person" to describe the party for whom a special means of service of process was appropriate. Rule 1-017(C) uses the phrase "incompetent persons" and this subparagraph adopts the language of Rule 1-017 NMRA for consistency. See Rule 10-104(L) NMRA (defining an "incompetent" person).
The provision for service on a guardian or conservator is carried over from former Rule 1-004(F)(7) except that such service now may be in any manner provided in Paragraph F, G or L as appropriate, rather than, as formerly, only "by delivering a copy . . . to the conservator or guardian".
The provision requiring resort to the court to formulate a method of service where the incompetent person has no guardian or conservator is new. Former Rule 1-004(F)(8) provided that if no conservator or guardian had been appointed for an incapacitated person, service upon the incapacitated person would suffice. This provided inadequate assurance that the incapacitated person would have a meaningful opportunity to defend the action. To remedy this, this subparagraph requires the court to fashion a constitutionally-adequate means of service upon the incapacitated person not represented by a guardian or conservator.
Subparagraph 3; Service on fiduciaries. This provision is carried over from former Rule 1-004(F)(9). Fiduciaries may be served in the same manner as individuals and business entities who are defendants.
Service in manner approved by court; Rule 1-004(J)
This provision is carried over, unchanged, from former Rule 1-004(L). The goal of service of process is to achieve actual notice by means that are reasonable under the circumstances. Rule 1-004(E)(1). The specific methods of service authorized in Rule 1-004 provide standard methods by which this can be accomplished, but there are myriad specific circumstances in which ad-hoc determination of the most appropriate means for serving process is called for. This rule provides broad authority for the court to fashion a constitutionally-adequate method of service under any circumstances.
Where service can be accomplished pursuant to Rule 1-004(F)(G)(H) or (I), there will seldom be need for resort to Rule 1-004(K). Where the court orders service by publication, the court should consider, pursuant to this Paragraph, whether supplemental means of service should accompany notice by publication. Where no method of service specifically provided for by Rule 1-004 is likely to satisfy or achieve the goal of actual notice, this Paragraph authorizes the court to create a method of service suited to the circumstances of the particular facts presented.
Service by publication; Rule 1-004(K)
This paragraph requires that no service by publication take place without a prior court order authorizing service by publication. This is a significant modification of prior practice in situations where statutes authorized publication without prior court approval. See, e.g., Section 42-2-7(B) NMSA 1978 (authorizing service by publication in condemnation proceeding "[i]f the name or residence of any owner be unknown"); Section 45-1-401 NMSA 1978 (authorizing service by publication in probate proceedings under some circumstances and providing that the court for good cause can provide a different manner of service). Publication notice is seldom likely to achieve actual notice and thus its use should be monitored carefully by the courts. The Supreme Court is authorized to modify statutes providing for notice by publication by requiring prior court approval for service by publication. Legislation affecting procedure is valid unless and until contradicted by a rule of procedure promulgated by the Supreme Court. Rule 1-091 NMRA; Section 38-1-2 NMSA 1978. This paragraph also provides the required content of the notice to be published, the frequency of publication and the place of publication. Omitted from the 2004 amendment is the former provision (Rule 1-004(H)(3)) requiring that publication be "in some newspaper published in the county where the cause is pending" and providing for publication in a newspaper of general circulation in the county only when "no newspaper [was] published in the county". Publication now always will include publication in a paper of general circulation in the county where the action is pending whether or not the newspaper is published in that county. Where appropriate to the goal of achieving actual notice, the court is free to require, in addition, that publication also be in a newspaper not of general circulation that is published in the county where the cause is pending.
Where the court determines that actual notice by publication is more likely to be achieved by publishing the notice elsewhere, the court must provide for additional published notice in the county that the court deems such notice is most likely to achieve the goal of actual notice to the defendant.
Former Rule 1-004(H)(7), dealing with the required content of repeated publications due to misnomers in the initial publication, has been omitted. The court that orders additional publication will craft an appropriate order concerning its content.
Former Rule 1-004(I) calling for publication to be accompanied by mail notice to persons whose residence is known has been omitted. The court that orders publication has the obligation to fashion means of service reasonably calculated to provide actual notice, Rule 1-004(E)(1), and thus can provide for mailed notice to accompany service of process by publication where reasonable. See Rule 1-004(J).
Proof of service; Rule 1-004(L)
The person obtaining service of process rather than the person serving process is now responsible for filing proof of service.
The means of proof of service when service is accomplished by mail or commercial courier service pursuant to Rule 1-004(F)(1)(b) and when service is made by publication pursuant to Rule 1-004(J) or (K) are provided in those paragraphs.
Service outside the state but in the United States; Rule 1-004(M)
This provision replaces former Rule 1-004(J) (Service of summons outside of state equivalent to publication). Where, as in the case of long arm jurisdiction pursuant to Section 38-1-16 NMSA 1978, service of process can be made outside of New Mexico, this rule requires that service be accomplished in the manner and priority provided in this rule. The Committee considered but rejected a proposal that the method of service need not meet the requirements of this rule so long as it met the requirements for service of process in the place where service occurred.
Service in a foreign country; Rule 1-004(N)
Service in foreign countries is sometimes subject to treaties or other international agreements. This rule, adopted from Federal Rule 4(f) and Rule 4(h)(2) takes into account the special considerations required by international law.
[Approved, March 1, 2005; as amended by Supreme Court Order No. 11-8300-050, effective for cases filed on or after February 6, 2012.]
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.
