Any person who is at least 18 years old and not a party may serve a subpoena. Serving a subpoena requires delivering a copy to the named person or service as otherwise ordered by the court consistent with due process.

A party or attorney responsible for issuing and serving a subpoena must take reasonable steps to avoid imposing undue burden or expense on a person subject to the subpoena. the issuing court must enforce this duty and impose an appropriate sanction, which may include lost earnings and reasonable attorney's fees, on a party or attorney who fails to comply.(2) Command to produce records or tangible things.(A) Attendance not required. A person commanded to produce records or tangible things need not attend in person at the place of production unless also commanded to attend for a deposition, hearing, or trial.(B) For production of privileged records.(I) If a subpoena commands production of records from a person who provides services subject to one of the privileges established by C.R.S. § 13-90-107 , or from the records custodian for that person, which records pertain to services performed by or at the direction of that person ("privileged records"), such a subpoena must be accompanied by an authorization signed by the privilege holder or holders or by a court order authorizing production of such records.(II) Prior to the entry of an order for a subpoena to obtain the privileged records, the court shall consider the rights of the privilege holder or holders in such privileged records, including an appropriate means of notice to the privilege holder or holders or whether any objection to production may be resolved by redaction.(III) If a subpoena for privileged records does not include a signed authorization or court order permitting the privileged records to be produced by means of subpoena, the subpoenaed person shall not appear to testify and shall not disclose any of the privileged records to the party who issued the subpoena.(C) Objections. Any party or the person subpoenaed to produce records or tangible things may submit to the party issuing the subpoena a written objection to inspecting, copying, testing or sampling any or all of the materials. The objection must be submitted before the earlier of the time specified for compliance or 14 days after the subpoena is served. If objection is made, the party issuing the subpoena shall promptly serve a copy of the objection on all other parties. If an objection is made, the party issuing the subpoena is not entitled to inspect, copy, test or sample the materials except pursuant to an order of the court from which the subpoena was issued. If an objection is made, at any time on notice to the subpoenaed person and the other parties, the party issuing the subpoena may move the issuing court for an order compelling production.(3) Quashing or modifying a subpoena.(A) When required. On motion made promptly and in any event at or before the time specified in the subpoena for compliance, the issuing court must quash or modify a subpoena that: (I) Fails to allow a reasonable time to comply;(II) Requires a person who is neither a party nor a party's officer to attend a deposition in any county other than where the person resides or is employed or transacts his business in person, or at such other convenient place as is fixed by an order of court;(III) Requires disclosure of privileged or other protected matter, if no exception or waiver applies; or(IV) Subjects a person to undue burden.(B) When permitted. To protect a person subject to or affected by a subpoena, the issuing court may, on motion made promptly and in any event at or before the time specified in the subpoena for compliance, quash or modify the subpoena if it requires: (I) Disclosing a trade secret or other confidential research, development, or commercial information; or(II) Disclosing an unretained expert's opinion or information that does not describe specific matters in dispute and results from the expert's study that was not requested by a party.(C) Specifying conditions as an alternative. In the circumstances described in Rule 45(c)(3)(B), the court may, instead of quashing or modifying a subpoena, order attendance or production under specified conditions if the issuing party: (I) Shows a substantial need for the testimony or material that cannot be otherwise met without undue hardship; and(II) Ensures that the subpoenaed person will be reasonably compensated.(d) Duties in responding to subpoena.(1) Producing records or tangible things.(A) Unless agreed in writing by all parties, the privilege holder or holders and the person subpoenaed, production shall not be made until at least 14 days after service of the subpoena, except that, in the case of an expedited hearing pursuant to these rules or any statute, in the absence of such agreement, production shall be made only at the place, date and time for compliance set forth in the subpoena; and(B) If not objected to, a person responding to a subpoena to produce records or tangible things must produce them as they are kept in the ordinary course of business or must organize and label them to correspond to the categories in the demand and must permit inspection, copying, testing, or sampling of the materials.(2) Claiming privilege or protection.(A) Information withheld. Unless the subpoena is subject to subsection (c)(2)(B) of this rule relating to production of privileged records, a person withholding subpoenaed information under a claim that it is privileged or subject to protection as trial-preparation material must: (I) Make the claim expressly; and(II) Describe the nature of the withheld records or tangible things in a manner that, without revealing information itself privileged or protected, will enable the parties to assess the claim.(B) Information produced. If information produced in response to a subpoena is subject to a claim of privilege or of protection as trial-preparation material, the person making the claim may notify any party that received the information of the claim and the basis for it. After being notified, a party must promptly return, sequester, or destroy the specified information and any copies it has; must not use or disclose the information until the claim is resolved; must take reasonable steps to retrieve the information if the party disclosed it before being notified; and may promptly present the information to the court under seal for a determination of the claim. The person who produced the information must preserve the information until the claim is resolved.(e) Subpoena for Deposition.(1) Residents of this state. A resident of this state may be required by subpoena to attend an examination upon deposition only in the county wherein the witness resides or is employed or transacts his business in person, or at such other convenient place as is fixed by an order of court.(2) Nonresidents of this state. A nonresident of this state may be required by subpoena to attend only within forty miles from the place of service of the subpoena in the state of colorado or in the county wherein the nonresident resides or is employed or transacts business in person or at such other convenient place as is fixed by an order of court.(3) Subpoena for deposition of an organization. A subpoena commanding a public or private corporation, partnership, association, governmental agency, or other entity to attend and testify at a deposition is subject to the requirements of Rule 30(b)(6). Responses to such subpoenas are also subject to Rule 30(b)(6).(f) Contempt. The issuing court may hold in contempt a person who, having been served, fails without adequate excuse to obey the subpoena. A nonparty's failure to obey must be excused if the subpoena purports to require the nonparty to attend or produce at a place outside the limits of Rule 45(e). Source: (c) amended and adopted October 30, 1997, effective January 1, 1998; (c) and (d)(1) amended and adopted December 14, 2011, effective January 1, 2012, for all cases pending on or filed on or after January 1, 2012, pursuant to C.R.C.P. 1(b); entire rule repealed and readopted and Committee Comments added October 18, 2012, effective January 1, 2013; amended and adopted by the Court, En Banc, January 6, 2022, effective 3/1/2022.
If a subpoena to attend a deposition is sought pursuant to Rule 45(c)(2)(A) in order to produce and authenticate documents, the issuing party should consider establishing admissibility under C.R.E. 902(11) as a means of reducing undue burden and expense upon the subpoenaed person.

The following annotations include cases decided under former provisions similar to this rule. Applied in Stubblefield v. District Court, 198 Colo. 569, 603 P.2d 559 (1979); Black ex rel. Bayless v. Cullar, 665 P.2d 1029 (Colo. App. 1983). II. Attendance of Witnesses. Protections not grounds for quashing subpoena. It was error for trial court to quash subpoena of a witness on the basis of the attorney-client privilege and attorney work product doctrine. These protections may be asserted at trial as a bar to specific questions, but are not grounds for quashing a subpoena properly issued. South Carolina Ins. Co. v. Fisher, 698 P.2d 1369 (Colo. App. 1984). A motion to quash subpoenas issued to third persons allegedly contributing to support of children is properly granted where the voluntary donations of such parties have nothing to do with a defendant's duty to support children. Garrow v. Garrow, 152 Colo. 480, 382 P.2d 809 (1963). III. Production of Documentary Evidence. A party seeking a "subpoena duces tecum" requiring production of documents by the other party must show good cause for the issuance of such a subpoena. Lee v. Missouri P. R. R. 152 Colo. 179, 381 P.2d 35 (1963). A "tangible thing" described in section (b) does not include real estate or fixtures. Thompson v. Thornton, 198 P.3d 1281 (Colo. App. 2008). For purposes of section (b), a subpoena duces tecum cannot compel the inspection of premises. Thompson v. Thornton, 198 P.3d 1281 (Colo. App. 2008). This rule must be read in conjunction with C.R.C.P. 34, governing the production of documents. Lee v. Missouri P. R. R., 152 Colo. 179, 381 P.2d 35 (1963). Colorado rules of civil procedure are not directly applicable to enforcement proceedings under the securities act. However, a court may consider the policies underlying section (b) of this rule in ruling on a motion for the advancement of costs incurred in complying with an administrative subpoena. Feigin v. Colo. Nat'l Bank, 897 P.2d 814 (Colo. 1995). In the exercise of their equitable authority, district courts may quash an administrative subpoena found to be unreasonable or oppressive. Feigin v. Colo. Nat'l Bank, 897 P.2d 814 (Colo. 1995). Where it was shown that a claim agent of a railroad could not give coherent story of an accident he investigated without first refreshing his memory from the file of such investigation, such evidence was sufficient to show good cause for the production of the file and it was error to quash a "subpoena duces tecum". Lee v. Missouri P. R. R., 152 Colo. 179, 381 P.2d 35 (1963). Trial court did not have discretion to order disclosure of psychologist's records during discovery, even for in camera review. Absent a clear waiver of psychologist-patient privilege, a trial court may not review documents related to a patient's treatment even in camera. People v. Sisneros, 55 P.3d 797 (Colo. 2002). Taxpayer has standing to raise legitimacy of access to records in motion to quash subpoena. Once the court allows intervention in a § 39-21-112 proceeding, it follows that a taxpayer with an expectation of privacy in his bank records has standing to raise the legitimacy of governmental access to the records in a motion to quash the subpoena for the records. Charnes v. DiGiacomo, 200 Colo. 94, 612 P.2d 1117 (1980). As a general rule, recipients of subpoenas in criminal proceedings must assume the cost of compliance as a matter of civic responsibility. However, an individualized determination is called for when it is claimed that the cost of compliance with a subpoena renders the subpoena itself unreasonable and oppressive. The person seeking to quash an administrative subpoena on such grounds has the burden of establishing the precise amount of the cost and that such amount exceeds the amount the recipient would reasonably be expected to incur as a civic responsibility. Feigin v. Colo. Nat'l Bank, 897 P.2d 814 (Colo. 1995). If an attorney desires to receive subpoenaed documents from a subpoenaed witness in advance of the time and place specified in the subpoena, or if the subpoenaed witness offers to produce the documents ahead of time, the attorney must confer with and obtain consent from all other parties to the case as well as the subpoenaed witness. If the other parties or the subpoenaed witness does not consent, then production must wait until the time and place of the event specified in the subpoena. Obtaining consent for the advance production of subpoenaed documents not only satisfies the procedural safeguards of this rule but also affords pragmatic accommodation to the realities of litigation practice. In re Wiggins, 2012 CO 44, 279 P.3d 1. Manner by which father's attorney obtained mother's former employment file and any other documents from mother's former place of employment in response to a subpoena violated rule. Rule requires that, unless subpoenaed witness and other parties consent to an alternate arrangement or by other court order, subpoenaed documents be produced only at the deposition, hearing, or trial specified in the subpoena. Attorney's unilateral arrangements violated rule because they prevented mother from having an opportunity to object to the subpoena before her entire employment file was disclosed. In re Wiggins, 2012 CO 44, 279 P.3d 1. IV. Service. Failure to find "good cause" for serving subpoena fewer than 48 hours in advance of appearance or to grant continuance held abuse of discretion. Montoya v. Career Serv. Bd., 708 P.2d 478 (Colo. App. 1985). Subpoenas that were served on Friday morning, directing the witnesses to appear on Monday morning, were not served 48 hours before the time the witnesses were to appear and were properly quashed. Wilkerson v. State, 830 P.2d 1121 (Colo. App. 1992). Service on registered agent. Personal delivery of interrogatories on foreign corporation's registered agent constitutes effective service. Isis Litig., L.L.C., v. Svensk Filmindustri, 170 P.3d 742 (Colo. App. 2007). V. Depositions. Section (d)(2) of this rule, relating to nonresidents, is limited solely to those persons who are either parties to the action or witnesses therein, both of which classes of nonresidents must first have been properly served in the action in order to subject them to the jurisdiction of the court, unless they have waived or consented to the jurisdiction of a Colorado court. Solliday v. District Court, 135 Colo. 489, 313 P.2d 1000 (1957); Minnesota ex rel. Minnesota Att'y Gen. v. District Court, 155 Colo. 521, 395 P.2d 601 (1964). This rule, as applied to nonresidents not parties to an action in Colorado and not served in Colorado, is subject to the implied limitations that nonresidents are subject to jurisdiction due to mutual compact or uniform act. Solliday v. District Court, 135 Colo. 489, 313 P.2d 1000 (1957); Minnesota ex rel. Minnesota Att'y Gen. v. District Court, 155 Colo. 521, 395 P.2d 601 (1964). Applied in CeBuzz, Inc. v. Sniderman, 171 Colo. 246, 466 P.2d 457 (1970). VI. Hearing or Trial. The refusal to reopen a compensation case for the purpose of taking testimony from a witness is not error where there was no showing that any subpoena was issued under the provisions of section (e) of this rule. Pacific Employers Ins. Co. v. Kirkpatrick, 111 Colo. 470, 143 P.2d 267 (1943).
