Searching Nassau County: what to expect
Searches in Nassau County run on two layers: a few county-run sources (2 below) and New York's statewide databases for everything else. You don't need a county-level docket here — New York courts are searchable statewide, mapped on our New York court records page. The standout local source is lrv.nassaucountyny.gov, covering parcel and property-tax data. For vital records there's no county-level source online — the statewide routes on the New York vital records page cover that piece.

The 4-Step Nassau County Records Pathway
1
Step 1 — Start at the Nassau County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Nassau County clerk's office is the first stop.
2
Step 2 — Use the New York statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the New York 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 Nassau County Records
MYTH"Nassau County maintains all criminal records."
FACTCriminal records for Nassau County are held by the New York state repository, NOT the county. The county sheriff has only the local arrest log.
MYTH"Records sealed in Nassau 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 Nassau County data."
FACTOnly the official New York state repository has verified, current Nassau County data. Free sites often have stale data.
MYTH"The Nassau County assessor's value is what I'll sell my home for."
FACTThe Nassau 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).

Frequently Asked Questions
Where do I find Nassau County property records?
Nassau County property records are maintained by the County Clerk, which records deeds, mortgages, and liens. Search the My Nassau Property - NassauCountyNY.gov portal directly: https://lrv.nassaucountyny.gov/.
Can my employer see a sealed record in New York?
Generally, most private employers running a standard name-based check cannot see a sealed New York record. However, government employers, law enforcement, schools, healthcare facilities, and any role requiring a fingerprint-based check can see sealed records under specific statutory exemptions. Confirm specifics with the sealing court.
Are New York marriage records public?
Marriage records in New York are generally public — anyone can verify that a marriage occurred and request a non-certified copy. Certified copies (needed for legal purposes like name changes or immigration) may be restricted to the spouses, immediate family, or those with a court order.
What's the difference between a court record and a criminal record in New York?
A court record shows everything filed in a specific case — pleadings, motions, judgments. A criminal record (rap sheet) is a person-centric history from the New York DCJS that aggregates arrests and dispositions across all courts in New York. Court records are searched by case; criminal records by person.
