Private Investigator in Boulder, CO for Counsel, Research Employers and Families

01Local knowledge

Why Boulder Cases Need an Investigator Who Understands the City's Layout

Boulder had about 105,689 residents in the 2025 Census estimate, a slight drop from 2020, and it is hemmed in by the foothills to the west and a ring of protected land. City voters approved a dedicated open space sales tax in 1967, and public accounts put Boulder's open space holdings above 61,000 acres. For field work, that means fewer through streets, busy trailhead lots and neighborhoods where a parked car is noticed. Our Colorado surveillance services plan positions with that visibility in mind.

US 36 carries most traffic between Boulder and the Denver metro, and state highways fan out toward Longmont, Lyons and the canyons. A subject can be in Louisville, Broomfield or the mountains within minutes, so we set handoff points and alternate routes before the first shift. When travel leaves Colorado, interstate surveillance continues under the same approved scope, and our statewide Colorado investigations overview explains how leadership supervises files that move.

• Population about 105,689 (2025 estimate)
• Open space limits through streets and cover
• US 36 links the city to the Denver metro

02Infidelity, family and custody

Relationship, Divorce and Parenting-Time Investigations in Boulder

Because Colorado grants divorce only on a finding that the marriage is irretrievably broken, an affair is not a legal ground for ending it. The facts can still matter when marital money pays for a second relationship or when one spouse's account of events will be tested in court. Our married infidelity investigations in Colorado record what actually happens from lawful vantage points, and financial and asset investigations look for accounts, property or business interests that were left off a disclosure.

Filing a Colorado divorce triggers an automatic temporary injunction under C.R.S. § 14-10-107 that, once the other spouse is served, generally bars hiding marital property, removing the children from Colorado without consent and cancelling key insurance. Parenting decisions then turn on the best-interest factors in C.R.S. § 14-10-124. We document exchanges, supervision and household conditions with dated entries, never involving the child. Unmarried co-parents can use our non-married relationship investigations under the same rules.

03Attorney and litigation support

Litigation Support for the Boulder County Combined Court and Federal Court

Boulder County makes up the 20th Judicial District. The Boulder County Combined Court sits at 1777 Sixth Street, with a second court location at 1035 Kimbark Street in Longmont. District court generally hears felonies, divorce and parenting cases and civil claims above $25,000, while county court takes smaller civil matters, misdemeanors and small claims up to $7,500. Our support for Colorado trial lawyers covers witness locates, recorded interviews and records work for either building.

Federal cases from Boulder County go to the U.S. District Court for the District of Colorado in Denver, with the clerk's office in the Arraj Courthouse on 19th Street. Counsel preparing for trial can order jury pool background research from public sources where the court permits it. The Colorado State Public Defender keeps a Boulder regional office, and both appointed and retained counsel use our misdemeanor defense investigations, which start at $750, and felony work starting at $1,000 per charge.

04Business, insurance and the local economy

Research Labs, Startups and Employer Investigations in Boulder

Boulder hosts federal research campuses, including NIST, NOAA and the National Center for Atmospheric Research, along with a deep bench of software, outdoor-industry and natural-products companies. Research employers worry less about stolen inventory than about code, data and designs leaving with a departing employee. Our trade secret and espionage investigations look at access records, timing and documented outside contacts, and corporate investigations in Colorado handle broader misconduct allegations with a written scope agreed in advance.

Startups also raise money, add partners and hire executives quickly, sometimes without much checking. Executive hire background checks review a candidate's litigation, prior companies and public conduct before an offer. Insurance carriers handling disputed claims can order insurance claim surveillance gathered lawfully in public places. Colorado treats a knowingly false workers' compensation statement as a class 6 felony under C.R.S. § 8-43-402, and our reports record facts that help the claimant as carefully as facts that do not.

05Locates, skip tracing and service

Finding People and Arranging Service Throughout Boulder County

Student leases that turn over each August, roommates who never sign the lease and frequent moves between Boulder, Lafayette and Longmont leave many database addresses out of date. We combine records research with an in-person check before calling any address current. Lost contact skip tracing finds old friends, heirs and former colleagues, and evasive person skip tracing is built for people who are actively avoiding contact or service.

When the person is found, Delator Field Services coordinates service in Boulder County with logged, time-stamped attempts and a signed affidavit. Routine Boulder County service has a published starting rate of $135, and the final figure is confirmed in writing before any attempt. Colorado's C.R.C.P. 4(e)(1) generally allows abode service only on a family member 18 or older, not a roommate, which matters in shared student housing. City details are on the Boulder process server page.

06Colorado legal limits

No State PI License in Colorado: Vetting an Investigator in Boulder

Colorado ended state licensing of private investigators after the governor vetoed the 2020 sunset bill, HB20-1207, and the program's rules were repealed in January 2022. A license number therefore tells you nothing about a Colorado investigator today. Ask instead for proof of liability insurance, a written scope with hours and price, a redacted sample report and the name of the supervisor responsible for your file. Our guide to vetting a Colorado investigator explains why each matters, and Delator Group holds Boulder files to its Tennessee license standard.

Lawful methods still matter in court. Third degree criminal trespass under C.R.S. § 18-4-504 covers simply entering or remaining on another's premises without right, so we work from public places and lawful vantage points. Harassment under C.R.S. § 18-9-111 includes following someone in public with intent to harass and repeated unwanted electronic messages, which is why our surveillance is planned to be unobtrusive and purposeful. Read what Colorado allows an investigator to do before hiring anyone.

• Proof of liability insurance
• Written scope with hours, travel and fee
• Redacted sample report
• A named supervisor for the file

07The university-town angle

Students, Parents and Campus-Area Cases in Boulder

The University of Colorado adds a large population of students and staff to Boulder; one public estimate puts its contribution at roughly 46,000 people. Many of those students have parents in other states who cannot simply drive over when calls stop being returned. When a family is worried, the first step is a welfare check or report through local police; CBI's Missing Persons Unit says local law enforcement must be notified before it becomes involved. Our missing person locate services then supplement that report rather than replacing it.

Campus-area work also includes dating safety, online harassment and housing disputes. A student who met someone through an app can order a dating background check that confirms identity and public history. Where anonymous accounts are targeting someone, cyberbullying investigations preserve messages and trace who is behind them for counsel or police. Landlords screening applicants for rentals near campus can use prospective tenant background checks, handled under applicable consumer reporting rules.
