Who Issues Warrants in Frederick
In Colorado an arrest warrant is signed by a judge. For Frederick that means the Weld County District Court, which hears felonies, civil cases over $25,000, divorces, probate and juvenile matters; the County Court, which takes misdemeanors, traffic cases and civil cases up to $25,000, issues its own warrants on the cases before it. A city with a municipal court of its own issues warrants on the tickets and ordinance cases it tries.
When a defendant misses a court date the judge issues a bench warrant, and either kind of warrant lives in the court file of the case, kept by the clerk of the combined court.
For Weld County, SearchSystems opened and checked the court records page for the county at coloradojudicial.gov/courts/trial-courts/weld-county (page title: Weld County | Colorado Judicial Branch), phone (970) 475-2400, Monday-Friday: 7:30 a.m. - 5:30 p.m., which answered when SearchSystems opened it on September 23, 2026.
Colorado has no single public index of every trial court case; each court's records are looked up through that court.
Who Serves Warrants in Frederick
The Weld County Sheriff's Office and the agency that reports for Frederick (filed by the FBI as Frederick Police Department) serve warrants in and around Frederick.
The FBI's agency list also places these agencies in Weld County: the University of Northern Colorado (campus police); Weld County Drug Task Force (other agency); each serves warrants on its own ground.
The Brighton Police Department, the Northglenn Police Department, the Longmont Police Department and one more are each listed by the FBI across several counties including Weld County, so their arrests are not broken out for Weld County here.
The agency that serves a warrant from Weld County is whichever one finds the person; a Colorado warrant is valid across Colorado.
Together, the 21 agencies in Weld County with all twelve months of 2025 on file reported 10,660 arrests to the FBI that year; arrests on warrants are counted among them, not separately.
Each agency and what it reported is in Frederick arrest records.
Where a Person Arrested on a Warrant from Frederick Is Held
A person arrested on a warrant and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Weld County Sheriff's Office, held about 590 people on an average day in 2025 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at weldsheriff.com/Services/Jail-Reports, phone 970-356-4015. The Frederick inmate search guide covers the jail in full.
A person arrested in Frederick on a warrant from another county is held at the same jail until that county takes custody.
How to Check for a Warrant in Frederick
Whether a warrant is out from Frederick shows in two places:
- The court file of the case, through the clerk of the combined court at (970) 475-2400, since a warrant is recorded in the case it was issued in.
- The District Attorney, phone (970) 400-4750, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Weld County pages SearchSystems verified (the sheriff's, the court's and the prosecutor's) is a list of open warrants, so a check means asking the court or the prosecutor about a case by name.
Clearing a Warrant from Frederick
A warrant is recalled by the court that issued it, so clearing one from Frederick starts with the clerk of the combined court at (970) 475-2400: the case goes back on the calendar and the judge recalls the warrant when the person appears.
A missed date in a case before the County Court is handled by that court, not by the Weld County District Court.
A lawyer can often arrange the appearance in advance. The District Attorney's page SearchSystems verified is at weld.gov, phone (970) 400-4750.
