Searching New Castle County: what to expect
New Castle County keeps a modest online footprint — 2 of the 14 sources below are the county's own; the rest is statewide coverage. You don't need a county-level docket here — Delaware courts are searchable statewide, mapped on our Delaware court records page. Locally, newcastlede.gov takes care of local vital-records requests, while www3.newcastlede.gov covers parcel and property-tax data. One gap: recorded documents aren't published by the county itself. Use the Delaware recorded documents page for those. Anything not online lives with the county offices in Wilmington.

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