Searching Marin County: what to expect
Marin County does more online than most: 5 county-run sources below, which keeps courthouse trips to a minimum. California courts search county by county, and Marin County has no public online docket listed — case records mean the clerk's office, or the statewide options on the California court records page. Two local sources do most of the work — apps.marincounty.gov for parcel and property-tax data, cdaportal2.marincounty.org for deeds and recorded documents. The county posts nothing for vital records, so that search runs through the statewide sources on our California vital records page.

The 4-Step Marin County Records Pathway
1
Step 1 — Start at the Marin County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Marin 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 Marin County Records
MYTH"Marin County maintains all criminal records."
FACTCriminal records for Marin County are held by the California state repository, NOT the county. The county sheriff has only the local arrest log.
MYTH"Records sealed in Marin County are gone everywhere."
FACTSealing 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 Marin County data."
FACTOnly the official California state repository has verified, current Marin County data. Free sites often have stale data.
MYTH"The Marin County assessor's value is what I'll sell my home for."
FACTThe Marin County assessor's value is for property tax purposes only — usually below market value.
MYTH"All county records older than 50 years are public."
FACTPartially 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).
