Who Issues Warrants in Hillsborough
In California an arrest warrant is signed by a judge. For Hillsborough that means the Superior Court of California, County of San Mateo, which hears every civil, criminal, family, probate, traffic 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 Superior Court clerk keeps that file.
The court records page SearchSystems verified for the county is at sanmateo.courts.ca.gov/online-services/information-accessing-your-c... (page title: Information on Accessing Your Case Online | Superior Court of California | County of San Mateo), phone 650-261-5100, 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 Hillsborough
The San Mateo County Sheriff's Office and the agency that reports for Hillsborough (filed by the FBI as Hillsborough Police Department) serve warrants in and around Hillsborough.
The FBI's agency list also places three other agencies and one state police unit in San Mateo County (the arrest records guide names each one); each serves warrants on its own ground.
A warrant issued in San Mateo County is good anywhere in California, so it is served by whichever agency finds the person, in a traffic stop as often as at the door.
Together, the 17 agencies in San Mateo County with all twelve months of 2025 on file reported 13,525 arrests to the FBI that year; arrests on warrants are counted among them, not separately.
Each agency and what it reported is in Hillsborough arrest records.
Where a Person Arrested on a Warrant from Hillsborough Is Held
A person arrested on a warrant and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the San Mateo County Sheriff's Office, held about 930 people on an average day in 2025 by the Vera Institute of Justice's count.
A person arrested in Hillsborough on a warrant from another county is held at the same jail until that county takes custody.
How to Check for a Warrant in Hillsborough
The places to check for a warrant from Hillsborough:
- The court file of the case, through the Superior Court clerk at 650-261-5100, since a warrant is recorded in the case it was issued in.
- The District Attorney, phone (650) 363-4636, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the San Mateo 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.
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 Hillsborough
Only the judge who issued a warrant can recall it. For a case from Hillsborough that means appearing before the Superior Court of California, County of San Mateo, with the case put back on the calendar through the Superior Court clerk.
A lawyer can often arrange the appearance in advance. The District Attorney's page SearchSystems verified is at smcgov.org/da, phone (650) 363-4636.
