Who Issues Warrants in St. Charles County
In Missouri an arrest warrant is signed by a judge. For St. Charles County that means the St. Charles County Circuit Court, which hears every civil, criminal, family, probate and juvenile case, with associate circuit judges taking misdemeanors, traffic and small claims. A city with a municipal divisions 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 Circuit Clerk keeps that file.
