Who Issues Warrants in Grafton
In Wisconsin an arrest warrant is signed by a judge. For Grafton that means the Ozaukee 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 Ozaukee County, SearchSystems opened and checked the court records page for the county at ozaukeecounty.gov/190/Access-Court-Records (page title: Access Court Records | Ozaukee County, WI), which answered when SearchSystems opened it on September 23, 2026.

Who Serves Warrants in Grafton
The Ozaukee County Sheriff's Office and the agency that reports for Grafton (filed by the FBI as Grafton Police Department) serve warrants in and around Grafton.
The Bayside Police Department and the Newburg Police Department are each listed by the FBI across several counties including Ozaukee County, so their arrests are not broken out for Ozaukee County here.

How to Check for a Warrant in Grafton
Whether a warrant is out from Grafton 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 District Attorney, phone 262-284-8380, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Ozaukee County pages SearchSystems verified (the sheriff's, the court's, the prosecutor's and the records request page) 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 Grafton
Only the judge who issued a warrant can recall it. For a case from Grafton that means appearing before the Ozaukee County Circuit Court, with the case put back on the calendar through the Clerk of Circuit Court.
A lawyer can often arrange the appearance in advance. The District Attorney's page SearchSystems verified is at ozaukeecounty.gov/137/District-Attorney, phone 262-284-8380.
