The 4-Step Mariposa County Records Pathway
1
Step 1 — Start at the Mariposa County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Mariposa County clerk's office is the first stop.
2
Step 2 — Use the California statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the California state level — not by the county.
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.
4
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.
Five Things People Get Wrong About Mariposa County Records
❌ Myth: "Mariposa County maintains all criminal records."
✓ Truth: False. Criminal records for Mariposa County are held by the California state repository, NOT the county. The county sheriff has only the local arrest log.
❌ Myth: "Records sealed in Mariposa County are gone everywhere."
✓ Truth: False. Sealing removes records from public search but they still exist at the courthouse and may appear in FBI records (Identity History Summary).
❌ Myth: "Free 'instant background' sites have Mariposa County data."
✓ Truth: False. Only the official California state repository has verified, current Mariposa County data. Free sites often have stale data.
❌ Myth: "The Mariposa County assessor's value is what I'll sell my home for."
✓ Truth: False. The Mariposa County assessor's value is for property tax purposes only — usually below market value.
❌ Myth: "All county records older than 50 years are public."
✓ Truth: Partially false. Public-records rules vary by record type AND state. Court records and deeds are usually older-public; vital records remain restricted longer (often 75-125 years).

Frequently Asked Questions
How do I look up court cases in Mariposa County?
Mariposa County court cases are filed with the Clerk of the Superior Court. Search the Judicial Administration Records Requests | Superior Court of California | County of Mariposa portal: https://www.mariposa.courts.ca.gov/general-information/judicial-administration-records-requests. For federal matters, see PACER.
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.
How do I find someone in ICE custody?
Use the ICE Online Detainee Locator System (locator.ice.gov). You can search by A-number (alien registration number) or by biographical information (name, country of birth, date of birth). The system covers adult detainees currently in ICE custody.
