Who Issues Warrants in Sonoma County
In California an arrest warrant is signed by a judge. For Sonoma County that means the Superior Court of California, County of Sonoma, which hears every civil, criminal, family, probate, traffic and juvenile case.
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 Superior Court clerk.
The court records page SearchSystems verified for the county is at sonoma.courts.ca.gov/online-services/case-portal (page title: Case Portal | Superior Court of California | County of Sonoma), which answered when SearchSystems opened it on September 23, 2026.
California has no single public index of every trial court case; each court's records are looked up through that court.
Who Serves Warrants in Sonoma County
The Sonoma County Sheriff's Office and the agencies that report for Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg, Sonoma and three more cities serve warrants in Sonoma County.
The FBI's agency list also places three state agencies, two campus police departments, one other agency and one state police unit in Sonoma County (the arrest records guide names each one); each serves warrants on its own ground.

The jail, run by the Sonoma County Sheriff's Office, held about 680 people on an average day in 2025 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at sonomasheriff.org/reports-and-statistics.

How to Check for a Warrant in Sonoma County
The places to check for a warrant from Sonoma County:
- The court file of the case, through the Superior Court clerk, since a warrant is recorded in the case it was issued in.
- The District Attorney, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Sonoma 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.
The statewide criminal history kept by the California Department of Justice is not open to the public in California, so it is not a route to a warrant check on someone else.
Clearing a Warrant from Sonoma County
A warrant is recalled by the court that issued it, so clearing one from Sonoma County starts with the Superior Court clerk: 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 District Attorney's page SearchSystems verified is at da.sonomacounty.ca.gov.
