such entity or person, or by delivery to a person authorized by appointment or law to
receive service of process for such entity or person. The delivery shall be made in any
manner permitted by such appointment or law.
(e) Substitute Service. In the event that a party attempting service of process by
personal service under section (d) is unable to accomplish service, and service by publication or mail is not otherwise permitted under section (f), the party may file a motion,
supported by an affidavit of the person attempting service, for an order for substituted
service. The motion shall state (1) the efforts made to obtain personal service and the
reason that personal service could not be obtained, (2) the identity of the person to whom
the party wishes to deliver the process, and (3) the address, or last known address of the
workplace and residence, if known, of the party upon whom service is to be effected. If the
court is satisfied that due diligence has been used to attempt personal service under section
(d), that further attempts to obtain service under section (d) would be to no avail, and that
the person to whom delivery of the process is appropriate under the circumstances and
reasonably calculated to give actual notice to the party upon whom service is to be
effective, it shall:
(1) Authorize delivery to be made to the person deemed appropriate for service, and
(2) Order the process to be mailed to the address(es) of the party to be served by
substituted service, as set forth in the motion, on or before the date of delivery.
Service shall be complete on the date of delivery to the person deemed appropriate for
service.
(f) Other Service. Except as otherwise provided by law, service by mail or publication
shall be allowed only in actions affecting specific property or status or other proceedings in
rem. When service is by publication, the complaint need not be published with the
summons. The party desiring service of process by mail or publication under this section
(f) shall file a motion verified by the oath of such party or of someone in the party’s behalf
for an order of service by mail or publication. It shall state the facts authorizing such
service, and shall show the efforts, if any, that have been made to obtain personal service
and shall give the address, or last known address, of each person to be served or shall state
that this address and last known address are unknown. The court, if satisfied that due
diligence has been used to obtain personal service or that efforts to obtain the same would
have been to no avail, shall:
(1) Order the party to send by registered or certified mail a copy of the summons and
a copy of the complaint, addressed to such person at such address, requesting a return
receipt signed by addressee only. Such service shall be complete on the date of the filing of
proof thereof, together with such return receipt attached thereto signed by such addressee,
or
(2) Order publication of the summons in a newspaper published in the county in which
the action is pending. Such publication shall be made once each week for five successive
weeks. Within fifteen days after the order the party shall mail a copy of the summons and
complaint to each person whose address or last known address has been stated in the
motion and file proof thereof. Service shall be completed on the day of the last publication.
If no newspaper is published in the county, the court shall designate one in some adjoining
county.
(g) Manner of Proof. Proof of service shall be made as follows:
(1) If served personally, by a statement, certified by the sheriff, marshal or similar
governmental official, or a sworn or unsworn declaration by any other person completing
the service as to date, place, and manner of service.
(2) Repealed eff. March 23, 2006.
(3) If served by mail, a sworn or unsworn declaration showing the date of the mailing,
with the return receipt attached, where applicable.
(4) If served by publication, by a sworn or unsworn declaration that includes the
mailing of a copy of the summons, complaint and answer form where required.
(5) If served by waiver, by a sworn or unsworn declaration admitting or waiving
service by the person or persons served, or by their attorney.
(6) If served by substituted service, by a sworn or unsworn declaration as to the date,
place, and manner of service, and that the process was also mailed to the party to be served
by substituted service, setting forth the address(es) where the process was mailed.
(h) Amendment. At any time in its discretion and upon such terms as it deems just,
the court may allow any summons or proof of service thereof to be amended, unless it
clearly appears that material prejudice would result to the substantial rights of the party
against whom the summons issued.
(i) Waiver of Service of Summons. A defendant who waives service of a summons
does not thereby waive any objection to the venue or to the jurisdiction of the court over
the defendant.
(j) Refusal of Copy. If a person to be served refuses to accept a copy of the summons
and complaint, service shall be sufficient if the person serving the documents knows or has
reason to identify the person who refuses to be served, identifies the documents being
served as a summons and complaint, offers to deliver a copy of the documents to the
person who refuses to be served, and thereafter leaves a copy in a conspicuous place.
(k) Time Limit for Service. If a defendant is not served within 26 weeks after the
complaint is filed, the court—on motion or on its own after notice to the plaintiff—shall
dismiss the action without prejudice against that defendant or order that service be made
within a specified time. But if the plaintiff shows good cause for the failure, the court shall
extend the time for service for an appropriate period. This subdivision (k) does not apply
to service in a foreign country under rule 304(d).
History
Source: Entire rule amended July 22, 1993, effective January 1, 1994; entire rule amended and effective March 23, 2006; (g)(1) amended and effective February 7, 2008; (d)(1) and (d)(4) amended and effective June 21, 2012; (g)(1), (3), (4), (5), (6) amended and comment added, effective April 17, 2020; (b) amended and effective October 13, 2021 (Rule Change 2021(21)); (k) added and effective January 6, 2022 (Rule Change 2022(02)). COMMENT Rule 304(g) on the manner of proving service was amended following the adoption in 2018 of the Uniform Unsworn Declarations Act. C.R.S. § 13-27-101 et seq. This Act defines a ‘‘sworn declaration,’’ which includes an affidavit, and an ‘‘unsworn declaration,’’ which ‘‘means a declaration in a signed record that is not given under oath, but is given under penalty of per- jury.’’ § 13-27-102 (6) and (7). An unsworn declaration which complies with the Act is suf- ficient to prove service under Rule 304(g).
