Colorado process server—service of process in all 64 counties

Colorado folds abode and workplace delivery into personal service itself. A non-party server 18 or older hands the summons and complaint to the defendant, leaves them at the defendant's usual home with an adult family member, or at the usual workplace with a supervisor, secretary, administrative assistant, bookkeeper, human resources representative, or managing agent—or delivers to an agent authorized by appointment or law.

C.R.C.P. 4(e)(1): "Upon a natural person whose age is eighteen years or older by delivering a copy thereof to the person, or by leaving a copy thereof at the person's usual place of abode, with any person whose age is eighteen years or older and who is a member of the person's family, or at the person's usual workplace, with the person's supervisor, secretary, administrative assistant, bookkeeper, human resources representative or managing agent; or by delivering a copy to a person authorized by appointment or by law to receive service of process." — Colo. R. Civ. P. 4(e)(1)

With ABC Legal: a vetted server makes the first attempt on your tier's timeline—as fast as 48 hours—and EvidenceChain™ records the GPS location and timestamp of the exact delivery moment.

In Colorado, substituted service is a court-ordered last resort—not a routine leave-a-copy option. After personal service under section (e) cannot be accomplished and mail or publication isn't available, the party files a motion with an affidavit detailing diligent efforts. If the court finds due diligence, it authorizes delivery to an appropriate person and orders the process mailed; service is complete on delivery.

C.R.C.P. 4(f): "In the event that a party attempting service of process by personal service under section (e) is unable to accomplish service, and service by publication or mail is not otherwise permitted under section (g), the party may file a motion, supported by an affidavit of the person attempting service, for an order for substituted service." — Colo. R. Civ. P. 4(f)

With ABC Legal: courts only accept substituted service after documented diligence. Our app geotags and timestamps every attempt automatically, so your diligence record is built before you need it.

Colorado sharply limits this method. Under Rule 4(g), service by mail or publication is available only in actions affecting property or status—never a shortcut for money claims. On a verified motion showing due diligence, the court may order publication once a week for five weeks, with a copy mailed within fourteen days; service is complete on the last publication.

C.R.C.P. 4(g): "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. ... Such publication shall be made once each week for five successive weeks. Within 14 days after the order the party shall mail a copy of the process ... Service shall be complete on the day of the last publication." — Colo. R. Civ. P. 4(g)

With ABC Legal: our skip tracing team locates most "unfindable" defendants before you ever pay for publication—and if it truly comes to that, your ABC attempt history is the diligence evidence the motion needs.

Colorado's entity rule reaches corporations, partnerships, LLCs, cooperatives, associations, and trusts alike. Deliver a copy to the registered agent named in the most recent Secretary of State filing, or to an officer, general partner, manager, member, or trustee. If none of those can be found in the state, service may instead reach a shareholder, director, agent, or principal employee who is located in Colorado.

C.R.C.P. 4(e)(4): "Upon any form of corporation, partnership, association, cooperative, limited liability company, limited partnership association, trust, organization, or other form of entity ... by delivering a copy thereof to the registered agent for service as set forth in the most recently filed document in the records of the secretary of state ... or one of the following: (A) An officer ... (B) A general partner ... (C) A manager ... (D) A member ... (E) A trustee of a trust ...." — Colo. R. Civ. P. 4(e)(4)

With ABC Legal: we verify the current registered agent against state records before dispatch, so the serve lands on the right desk the first time.

The target dictates the recipient. Serve the State through the attorney general; a state officer or agency requires copies to both that office and the attorney general. Serve a municipality through its mayor, manager, clerk, or deputy clerk; a county through the county clerk, chief deputy, or a commissioner; a school district through the superintendent; special districts through any officer or general manager.

C.R.C.P. 4(e)(9): "Upon the state by delivering a copy thereof to the attorney general." 4(e)(6): "Upon a municipal corporation, by delivering a copy thereof to the mayor, city manager, clerk, or deputy clerk." 4(e)(7): "Upon a county, by delivering a copy thereof to the county clerk, chief deputy, or county commissioner." 4(e)(8): "Upon a school district, by delivering a copy thereof to the superintendent." 4(e)(11): "Upon other political subdivisions ... special districts, or quasi-municipal entities, by delivering a copy thereof to any officer or general manager ...." — Colo. R. Civ. P. 4(e)(6)–(11)

With ABC Legal: our servers handle city, county, and state entity serves routinely—and know exactly which office actually accepts them.
