The 4-Step Nantucket County Records Pathway
1
Step 1 — Start at the Nantucket County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Nantucket County clerk's office is the first stop.
2
Step 2 — Use the Massachusetts statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the Massachusetts 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 Nantucket County Records
❌ Myth: "Nantucket County maintains all criminal records."
✓ Truth: False. Criminal records for Nantucket County are held by the Massachusetts state repository, NOT the county. The county sheriff has only the local arrest log.
❌ Myth: "Records sealed in Nantucket 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 Nantucket County data."
✓ Truth: False. Only the official Massachusetts state repository has verified, current Nantucket County data. Free sites often have stale data.
❌ Myth: "The Nantucket County assessor's value is what I'll sell my home for."
✓ Truth: False. The Nantucket 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
How do I look up court cases in Nantucket County?
Nantucket County court cases are searchable through the Courts serving Nantucket | Mass.gov portal: https://www.mass.gov/info-details/courts-serving-nantucket. Massachusetts also operates a state-level case lookup through the MassCourts system. For federal matters, see PACER.
Are Massachusetts marriage records public?
Marriage records in Massachusetts 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.
Does an active warrant show up on a background check in Massachusetts?
Yes. Active warrants in Massachusetts appear on name-based criminal background checks through the Massachusetts CHSB system the moment they are entered. Some employers also run a separate NCIC warrant query, which catches federal warrants as well.
Will a criminal conviction lead to deportation?
It depends on the offense, the person's immigration status, and current federal enforcement priorities. Aggravated felonies and crimes of moral turpitude carry the highest immigration risk. Even a sealed or expunged state conviction may still count under federal immigration law. Consult an immigration attorney.
