The summons must include the name, address, and registration number of the plaintiff’s attorney as per Colorado Process Service. Unless the complaint is served by publication or the court orders otherwise, it must be served with the summons. A summons alone will not constitute a service of process. A copy of the summons’ special order must be served with the summons in any situation where personal service is permitted without the complaint.

A copy of the document should be sent to the mayor, city manager, clerk, or deputy clerk of the municipal corporation in question. If an individual wants to provide Colorado Process Service to a county, one may do so by giving a copy to the county clerk, chief deputy, or county commissioner.

For school districts, the superintendent or any other person authorized to accept Colorado Process Service might get a copy by handing the document over. By presenting a copy of the document to the attorney general or to any employee authorized by them to receive Colorado Process Service, the state may be served.

It is possible to serve the process on a public official by providing a copy of it to that person, as well as delivering a copy of the Colorado Process Service to the attorney general or any employee of his office who has been assigned the task of accepting service of process.

If an individual is going to sue a state agency, they have to give copies of the summons and complaint to the agency’s higher officials, as well as to the attorney general or any employee authorized by them to receive Colorado Process Service.

The date of service on the officer, agent, employee, department, or agency governs for all purposes. However, failure to serve copies on the attorney general within three days of service on the officer, agent, employee, department, or agency shall extend the time within which the officer, agent, employee, department, or agency must file a responsive pleading for sixty days beyond the time. 

Only actions involving individual property or status or other rem processes may be served by mail or publishing. One must submit a motion for an order of service by publication or mail, confirmed by the oath of the individual or another person acting on their behalf.

If personal service has been attempted, it must identify the efforts made and the address or last known address of each person to be served. Alternatively, it must say that the address and last known address of each person to be served are unknown. To determine whether appropriate diligence was made to secure personal service or if such attempts would have failed, the court will conduct an ex parte.


To determine whether appropriate diligence was made to secure personal service or if such attempts would have failed, the court will conduct an ex parte hearing. In this hearing, it is necessary to order the clerk to mail a copy of the Colorado Process Service to such individual at the address, demanding a return receipt signed solely by the addressee via registered or certified mail. It will be considered served when the clerk’s proof of service and the return receipt attached thereto are both received and signed by the intended recipient. Alternatively, this could be published via a newspaper published in the county where the case is pending and should be ordered to disclose the procedure of the action. For the next four weeks, this publication will be available. 

The clerk must send a copy of the Colorado Process Service to each individual whose address or last known address was listed in the motion within fifteen days of the order. On the final day of publishing, the Colorado Process Service will be completed. If there is no newspaper in the county, the court will appoint one in an adjacent county.


Any objections to the venue or the court’s jurisdiction over the defendant’s person are unaffected by a defendant waiving the serving of a summons.  The person putting out the Colorado Process Service must know or have cause to know the identity of the person who refuses to be served, as well as the papers being served, and must offer to provide a copy of the documents to that person if they refuse to receive a copy of the Colorado Process Service.

Except for new or additional claims for relief, pleadings stating new or additional claims for relief against parties in default for non-appearance need not be served on them.


If a party represented by an attorney needs to be served, the Colorado Process Service must be done unless the court directs personal service to the party. In order to serve documents on a resident attorney, they must be an attorney of record for any foreign attorney who practices in any court in this state. If the pleadings have not been filed or the party’s address has not been provided, the clerk of the court may serve the attorney or party by delivering a copy to the attorney, mailing it to the attorney’s address, or sending it via facsimile machine transmission to the pleadings’ designated facsimile number.

If an attorney or the party is not present, a copy of a document can be delivered by handing it to them or, if there is no one to hand it to but the person to be served as a place of residence or office, it can be left at that location with a member of their family over eighteen years of age. If the office is closed or the person to be served does not have a home, the copy can be delivered to the person’s residence or place of residence by leaving it with an adult member of the family over eighteen years of age. After providing the same, the Colorado Process Service is complete.


Court proceedings must be the only place where interrogatories are submitted. If they are not utilized in court, they cannot be filed until they are. Papers must be submitted either before Colorado Process Service or within a reasonable time following Colorado Process Service if they are to be served alone. A certificate of service must be attached to any subsequent documents needed to be served upon a party.

Pleadings and other documents must be submitted to the clerk of the court unless specifically permitted to be filed by the judge. There will be a filing date noted on these documents, and they will be promptly sent to the clerk’s office by the judge.


A subpoena is a primary means of gathering documentary proof. The individual to whom a subpoena is issued may also be required to provide the books, papers, records, or other items listed in the summons. Although it is possible for the court to quash or modify a subpoena if it is arbitrary and oppressive or to condition denial of a motion on advance payment of the reasonable cost of producing the books, papers, documents, and tangible things if a timely motion is made and is made at or before the time specified in the subpoena for compliance.

The individual identified in the subpoena will be served with a copy of the subpoena and the fees and mileage authorized by law for one day’s attendance, which will be delivered to them. If the individual mentioned in the subpoena has signed a written admission or waiver of personal service, then service is also legal in that instance. 

A subpoena must be delivered at least forty-eight hours before the scheduled attendance time unless the court orders differently for a good reason. It is the responsibility of the party issuing or causing to be issued, except in post-judgment proceedings, the subpoena required by this rule, to serve a copy of the subpoena on all parties of record, including pro se parties. The other parties will be served as soon as the person specified in the subpoena has been served. The court does not need the original subpoenas and returns of service of such subpoenas to be submitted.


Within ten days after delivery of a subpoena for a person to serve on the designated attorney in the subpoena, a written objection to the examination or copying of any or all identified papers should be provided if such period is less than ten days after Colorado Process Service. Subpoenaed documents may only be seen and copied by the party serving the subpoena if the court issued the subpoena.

A subpoena may only compel a resident of this state to appear for a deposition examination in the county where they live, work, or conduct business in person or at another convenient location as determined by order of the court. It is only within forty miles of the place of service or the county where a non-resident lives, works, or does business that a non-resident may be summoned to appear by subpoena and at such other convenient location as the court may specify.

The clerk of the court may issue subpoenas for attendance at a deposition, hearing, or trial. One of the attorneys whose attendance has been entered in the specific matter for which a subpoena is sought dockets the case. If a witness is required to appear for a deposition, hearing, or trial, a subpoena may be issued at any location in the state.

how to domesticate an OUT-OF-STATE SUBPOENA in Colorado

Issuing an out-of-state subpoena pursuant to the Uniform Interstate Deposition and Discovery Act (UIDDA)-Colorado, the clerk of the court in the county where discovery is to be performed in this state must be presented with a foreign subpoena before it may be requested that a subpoena be issued under this section. Subpoenas issued under this law do not obligate a person to appear in court in Colorado.
