Who Issues Warrants in Half Moon Bay
In California an arrest warrant is signed by a judge. For Half Moon Bay that means the Superior Court of California, County of San Mateo, 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.

How to Check for a Warrant in Half Moon Bay
The places to check for a warrant from Half Moon Bay:
- 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 Half Moon Bay
A warrant is recalled by the court that issued it, so clearing one from Half Moon Bay starts with the Superior Court clerk at 650-261-5100: 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 smcgov.org/da, phone (650) 363-4636.
