Searching Mariposa County: what to expect
Mariposa County publishes some records directly — 2 local sources below — and leans on state systems for the rest. California courts search county by county, and Mariposa County has no public online docket listed — case records mean the clerk's office, or the statewide options on the California court records page. Locally, mariposacounty.gov takes care of the sheriff's side — jail roster and inmate lookups, while mariposacounty.org covers local vital-records requests. The county posts nothing for property records, so that search runs through the statewide sources on our California property records page.

3
Step 3 — Federal sources for federal records
Federal court cases (PACER), federal tax liens (IRS), military records (NPRC), and immigration data (ICE) are all federal — not held by the county.

Step 4 — Cross-check before relying on data
Most county portals lag 24-48 hours behind the courthouse. For time-sensitive verification, call the clerk directly.

What's the difference between sealing and expunging a record in California?
In California, a sealed record is hidden from public view but still exists and remains visible to law enforcement, licensing boards, and some employers. An expunged record is treated by California law as if it never happened — though FBI and federal records may persist regardless of state action. The relief process runs through the sentencing court.
How long does an arrest stay on my record in California if I wasn't convicted?
In California, an arrest stays on your record indefinitely unless you petition the court to seal or expunge it, even if charges were dropped or you were found not guilty. California's rules for clearing non-conviction records are stricter than for convictions — start with the California Department of Justice.
