Who Issues Warrants in Platteville
In Wisconsin an arrest warrant is signed by a judge. For Platteville that means the Grant 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.
The court records page SearchSystems verified for the county is at wicourts.gov/casesearch.htm (page title: Wisconsin Court System | Case search), which answered when SearchSystems opened it on September 23, 2026.

How to Check for a Warrant in Platteville
The places to check for a warrant from Platteville:
- 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 (608) 723-4237, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Grant County pages SearchSystems verified (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.
