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."
✓ Truth: False. Criminal 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."
✓ 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 New Castle County data."
✓ Truth: False. Only 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."
✓ Truth: False. The 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."
✓ 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 New Castle County property records?
New Castle County property records are maintained by the Recorder of Deeds, which records deeds, mortgages, and liens. Search the Parcel Search - New Castle County, DE portal directly: https://www3.newcastlede.gov/parcel/search/.
Are Delaware marriage records public?
Marriage records in Delaware 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.
How long does an arrest stay on my record in Delaware if I wasn't convicted?
In Delaware, 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. Delaware's rules for clearing non-conviction records are stricter than for convictions — start with the Delaware State Police.
What's the difference between a court record and a criminal record in Delaware?
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 Delaware State Police that aggregates arrests and dispositions across all courts in Delaware. Court records are searched by case; criminal records by person.
