Who Issues Warrants in Cornelius
In Oregon an arrest warrant is signed by a judge. For Cornelius that means the Washington County Circuit Court, which hears every civil, criminal, family, probate and juvenile case. A city with a municipal and justice court of its own issues warrants on the tickets and ordinance cases it tries.
A bench warrant follows a missed court date in any of those courts. Whichever kind it is, the warrant is part of the file of the case it was issued in, and the trial court administrator keeps that file.
For Washington County, SearchSystems opened and checked the court records page for the county at courts.oregon.gov/courts/washington/records/pages/default.aspx (page title: Oregon Judicial Department : Court Records | Home : Court Records : State of Oregon), 150 N 1st Avenue, Rm. 110J Hillsboro, OR 97124, which answered when SearchSystems opened it on September 24, 2026.

Who Serves Warrants in Cornelius
The Washington County Sheriff's Office and the agency that reports for Cornelius (filed by the FBI as Cornelius Police Department) serve warrants in and around Cornelius.
The FBI's agency list also places these agencies in Washington County: the Washington County Liquor Commission (state agency); the Hillsboro School District (other agency); the Washington County State Police (state police); each serves warrants on its own ground.
The Portland Police Department and the Lake Oswego Police Department are each listed by the FBI across several counties including Washington County, so their arrests are not broken out for Washington County here.
The agency that serves a warrant from Washington County is whichever one finds the person; an Oregon warrant is valid across Oregon.
Together, the 12 agencies in Washington County with all twelve months of 2025 on file reported 18,060 arrests to the FBI that year; arrests on warrants are counted among them, not separately.
Each agency and what it reported is in Cornelius arrest records.
Where a Person Arrested on a Warrant from Cornelius 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 Washington County Sheriff's Office, held about 420 people on an average day in 2023 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at washingtoncountyor.gov/sheriff/jail, phone 503-846-6374. The Cornelius inmate search guide covers the jail in full.
A person arrested in Cornelius on a warrant from another county is held at the same jail until that county takes custody.
How to Check for a Warrant in Cornelius
The places to check for a warrant from Cornelius:
- The court file of the case, through the trial court administrator, since a warrant is recorded in the case it was issued in.
- Oregon eCourt Case Information, the Oregon Judicial Department's online case search, free for basic case information, for a case whose register of actions shows a warrant.
- The District Attorney, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Washington 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 Cornelius
A warrant is recalled by the court that issued it, so clearing one from Cornelius starts with the trial court administrator: the case goes back on the calendar and the judge recalls the warrant when the person appears.
A lawyer can often arrange the appearance in advance. The District Attorney's page SearchSystems verified is at washingtoncountyor.gov.
