Searching Union County: what to expect

Don't expect a county web presence here: Union County's records live in state systems and filing cabinets, not on local sites. The sources below are the statewide layer that covers the county. Court cases are the easy part: New Jersey's statewide search covers Union County filings, so start at the New Jersey court records page instead of hunting for a local docket. Anything not online lives with the county offices in Elizabeth.

The 4-Step Union County Records Pathway

1
Step 1 — Start at the Union County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Union County clerk's office is the first stop.
2
Step 2 — Use the New Jersey statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the New Jersey 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 Union County Records

MYTH"Union County maintains all criminal records."
FACTCriminal records for Union County are held by the New Jersey state repository, NOT the county. The county sheriff has only the local arrest log.
MYTH"Records sealed in Union 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 Union County data."
FACTOnly the official New Jersey state repository has verified, current Union County data. Free sites often have stale data.
MYTH"The Union County assessor's value is what I'll sell my home for."
FACTThe Union 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

How do I look up court cases in Union County?
Union County court cases are searchable through the Official Website of the New Jersey Judiciary | NJ Courts portal: https://www.njcourts.gov/. New Jersey also operates a state-level case lookup through the NJ Courts Online system. For federal matters, see PACER.
Can my employer see a sealed record in New Jersey?
Generally, most private employers running a standard name-based check cannot see a sealed New Jersey 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.
How long does an arrest stay on my record in New Jersey if I wasn't convicted?
In New Jersey, 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. New Jersey's rules for clearing non-conviction records are stricter than for convictions — start with the New Jersey State Police.
How do I run a New Jersey background check?
New Jersey background checks are handled by the New Jersey State Police. Name-based searches are available through the official state portal (per-search fee applies). Fingerprint-based checks — required for licensing, foster care, and many employers — must be submitted through an approved vendor.
