Who Issues Warrants in Waterloo
In Iowa an arrest warrant is signed by a judge. For Waterloo that means the Iowa District Court for Black Hawk County, which hears every civil, criminal, family, probate and juvenile case.
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 Clerk of the District Court keeps that file.
The court records page SearchSystems verified for the county is at iowacourts.gov/iowa-courts/district-court/judicial-district-1/distr... (page title: Black Hawk | Judicial District 1 | Iowa Judicial Branch), phone 319-833-3331, 316 E. 5th Street Waterloo, IA 50703, which answered when SearchSystems opened it on September 24, 2026.

How to Check for a Warrant in Waterloo
Whether a warrant is out from Waterloo shows in four places:
- The court file of the case, through the Clerk of the District Court at 319-833-3331, since a warrant is recorded in the case it was issued in.
- Iowa Courts Online, the Iowa Judicial Branch's free statewide case search, for a case whose register of actions shows a warrant.
- The County Attorney, phone 319-833-3001, which can say whether charges were filed; a warrant on a complaint follows the filing.
- The custody page of the Black Hawk County Sheriff's Office at bhcso.org/whos-in-jail, which shows people already arrested and booked, not open warrants.
Not one of the Black Hawk 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 Waterloo
A warrant is recalled by the court that issued it, so clearing one from Waterloo starts with the Clerk of the District Court at 319-833-3331: 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 County Attorney's page SearchSystems verified is at blackhawkcounty.iowa.gov/716/Attorneys-Office, phone 319-833-3001.
