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."
✓ Truth: False. Criminal 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."
✓ 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 Nassau County data."
✓ Truth: False. Only 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."
✓ Truth: False. The 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."
✓ 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
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.
