Who Issues Warrants in Mason County
In Washington an arrest warrant is signed by a judge. For Mason County that means the Mason County Superior Court, which hears felonies, civil cases over $100,000, divorces, probate and juvenile matters; the District Court, which takes misdemeanors, traffic infractions, small claims and civil cases up to $100,000, issues its own warrants on the cases before it. 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 County Clerk.

How to Check for a Warrant in Mason County
The places to check for a warrant from Mason County:
- The court file of the case, through the County Clerk at 360-427-7776, since a warrant is recorded in the case it was issued in.
- Washington Courts Search Case Records, the Administrative Office of the Courts' free statewide case search, for a case whose register of actions shows a warrant.
- The Prosecuting Attorney, phone (360) 427-9670, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Mason 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 Mason County
