Who Issues Warrants in Greenfield
In Wisconsin an arrest warrant is signed by a judge. For Greenfield that means the Milwaukee County Circuit Court, which hears every civil, criminal, family, probate and juvenile case. 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 Circuit Court.
For Milwaukee County, SearchSystems opened and checked the court records page for the county at wicourts.gov/casesearch.htm (page title: Wisconsin Court System | Case search), which answered when SearchSystems opened it on September 23, 2026.
Statewide, Wisconsin Circuit Court Access is the free statewide case search of every circuit court.
Who Serves Warrants in Greenfield
The Milwaukee County Sheriff's Office and the agency that reports for Greenfield (filed by the FBI as Greenfield Police Department) serve warrants in and around Greenfield.
The FBI's agency list also places these agencies in Milwaukee County: the University of Wisconsin at Milwaukee and Marquette University (campus police); the State Fair Park Police (state agency); each serves warrants on its own ground.
The agency that serves a warrant from Milwaukee County is whichever one finds the person; a Wisconsin warrant is valid across Wisconsin.
Together, the 20 agencies in Milwaukee County with all twelve months of 2025 on file reported 28,168 arrests to the FBI that year; arrests on warrants are counted among them, not separately.
Each agency and what it reported is in Greenfield arrest records.
Where a Person Arrested on a Warrant from Greenfield 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 Milwaukee County Sheriff's Office, held about 2,170 people on an average day in 2025 by the Vera Institute of Justice's count and has a custody page SearchSystems verified at incustodysearch.milwaukeecountywi.gov. The Greenfield inmate search guide covers the jail in full.
A person arrested in Greenfield on a warrant from another county is held at the same jail until that county takes custody.
How to Check for a Warrant in Greenfield
Whether a warrant is out from Greenfield shows in three places:
- The court file of the case, through the Clerk of Circuit Court, since a warrant is recorded in the case it was issued in.
- Wisconsin Circuit Court Access, the free statewide case search of every circuit court, for a case whose register of actions shows a warrant.
- The custody page of the Milwaukee County Sheriff's Office at incustodysearch.milwaukeecountywi.gov, which shows people already arrested and booked, not open warrants.
Not one of the Milwaukee County pages SearchSystems verified (the sheriff's and the court'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 Greenfield
A warrant is recalled by the court that issued it, so clearing one from Greenfield starts with the Clerk of Circuit Court: the case goes back on the calendar and the judge recalls the warrant when the person appears.
