Arrest Records for Nantucket County, Massachusetts

Nantucket County criminal records live in two distinct systems: the Massachusetts Trial Court’s MassCourts portal covers court-side docket entries for cases filed at the Nantucket District Court, while booking-side records are held by the Nantucket Police Department — reachable at (508) 228-1212 — and the Nantucket County Sheriff’s Office, whose web presence is at Nantucket County Sheriff’s Office. Public records requests for town-held documents go through the Nantucket public records request portal. Note that sealed or expunged records will not appear in any standard search — see the expungement section below if that applies to your situation.

If someone you know was just booked tonight, our Nantucket County inmate-search page has phone-first contact info.

If you need records outside Nantucket County

A nationwide background check can surface arrest records from other Massachusetts counties or other states that local portals won’t reach. The preliminary scan is free; a full report requires creating an account. This tool is most useful when you’re checking records from multiple jurisdictions at once — for example, a paralegal pulling history across county lines.

How to look up arrest records in Nantucket County

What happens to a sealed or expunged record when you run a standard search? It disappears — the system returns nothing, as if the arrest never occurred. That’s by design under Massachusetts CORI law. If you’re checking a name and finding no results where you expected some, the record may have been sealed; the expungement section below explains the eligibility rules. For records that are publicly accessible, here are the four pathways that actually work for Nantucket County.

MassCourts public docket search. The Massachusetts Trial Court’s court dockets and case information portal lets you search by name or case number across all Trial Court departments, including the Nantucket District Court. You’ll see case numbers, charge descriptions, hearing dates, and dispositions for cases that are public. The portal covers District Court criminal matters — which is where most Nantucket County misdemeanor and lower-level felony cases are filed. If you need help navigating the interface, the state’s MassCourts user guide walks through the search steps. Land Court dockets — a separate department — are searchable via the Land Court docket search, though Land Court handles property matters, not criminal cases.

Nantucket Police Department records request. Booking records — the arrest-side documents generated when someone is taken into custody — are held by the Nantucket Police Department. Call (508) 228-1212 to ask about their records-request process. The department’s staff directory is published at Nantucket Police Department staff directory if you need to reach a specific records officer. Fees, turnaround times, and accepted request formats — call to confirm, as these details aren’t published online.

Nantucket County Sheriff’s Office records request. The Old Gaol — Nantucket’s county jail — is operated under the Sheriff’s Office. For jail-side booking records or custody history, contact the Old Gaol at (508) 228-7200. The Sheriff’s Office main page is at Nantucket County Sheriff’s Office, and the Massachusetts Sheriffs’ Association maintains a supplemental listing at Nantucket County Sheriff’s Office profile.

Massachusetts Department of Correction inmate lookup. If the person you’re researching may be held in a state prison rather than the county jail, the Massachusetts Department of Correction’s inmate lookup tool covers DOC facilities statewide. This is a separate system from the county jail — a name that returns nothing in the county jail search may still appear in the DOC lookup if the person was sentenced to state prison. For Nantucket County-specific public records requests beyond court dockets, the town’s public records request portal is the formal channel, governed by the Massachusetts Public Records Law.

Are Nantucket County arrest records public?

Court filings are public records under Massachusetts law — specifically M.G.L. c. 66, § 10 (with c. 4, § 7, cl. 26) — which establishes a default presumption of public access to government records. That presumption applies to Nantucket County court dockets, charging documents, and case dispositions held by the Trial Court. The practical result: anyone can search the MassCourts portal by name and retrieve docket entries for cases that haven’t been sealed or expunged.

The exceptions are narrow but significant. Sealed records — whether sealed by court order or by petition under M.G.L. c. 276, §§ 100A-100C — are invisible to the public. Expunged records under §§ 100E-100U are destroyed entirely. Juvenile records are categorically restricted; the Nantucket Juvenile Court handles those matters, and they don’t appear in standard public searches. Victim-protection redactions may remove identifying information from certain filings, particularly in domestic violence and sexual assault cases.

Massachusetts is among the more privacy-protective states on criminal records access. The CORI law (M.G.L. c. 6, §§ 167-178B) limits who can access a person’s full criminal history and under what circumstances. A general public search through MassCourts shows court-side docket information — it does not give you the same view that an employer with CORI authorization or a law enforcement agency would see. Law enforcement retains access to sealed records even after a successful petition; the public does not.

Booking photos (mugshots) from the Nantucket Police Department are not routinely published online. For the department’s current policy on releasing booking photos, call (508) 228-1212 — the policy isn’t posted on the department’s public-facing pages. The town’s broader public records framework is documented at the Nantucket Public Records Law page, which links to A Guide to the Massachusetts Public Records Law published by the Secretary of State’s office.

What’s in a Nantucket County arrest record?

From the moment an arrest is processed, the paper trail splits across systems — and what you can see depends on which system you’re looking at. A single arrest in Nantucket County can generate a booking entry at the police station, a citation or complaint document, and a court docket entry at the Nantucket County Courthouse, each with different fields and different access rules.

Booking-side records (held by the Nantucket Police Department or the Old Gaol) typically include: the arrestee’s name and date of birth, the booking date and time, the arresting officer’s name, the charge or charges as written at the time of arrest, and any bail or hold information. These records are generated at the point of custody. They reflect what the officer charged — not what the court ultimately found. A booking record showing an OUI charge doesn’t tell you whether the case was dismissed, reduced, or convicted.

Court-side docket entries at the Nantucket County Courthouse show what happened after the booking. The MassCourts portal surfaces: the case number (formatted by court department and year), the docket date, each charge as filed by the prosecutor, all scheduled and completed hearing dates, attorney of record if one appeared, and the disposition — guilty, not guilty, dismissed, nolle prosequi, continued without a finding, or other outcomes. Dispositions are the most legally significant field for background-check purposes, because Massachusetts sealing law treats conviction and non-conviction dispositions very differently.

A few fields you may not find in a standard public search: the full narrative of the police report (not part of the public docket), any sealed companion cases, and juvenile records. If a case involved multiple defendants or multiple charges that were resolved separately, each may carry its own docket entry — so one incident can produce several case numbers. When you’re doing a thorough records check, search by name across all case types, not just criminal, because civil restraining orders and other proceedings sometimes appear alongside criminal dockets in the same person’s history.

For cases that went to the Appeals Court or Supreme Judicial Court, the Appeals Court case information portal covers appellate-level dockets separately from the Trial Court system.

How to expunge an arrest record in Nantucket County

Petition in hand, courthouse door in sight — that’s the practical shape of the sealing process in Massachusetts. The Petition to Seal form is filed at the court where the original matter was adjudicated: for most Nantucket County criminal cases, that’s the Nantucket District Court. The Commissioner of Probation then effects the order once the court approves it.

Massachusetts offers two distinct forms of relief, and they work differently. Sealing under M.G.L. c. 276, §§ 100A-100C hides the record from public view — law enforcement can still see it, but employers, landlords, and the general public cannot. Expungement under M.G.L. c. 276, §§ 100E-100U permanently destroys the record. Expungement is the narrower path.

Non-conviction dispositions — dismissals, nolle prosequi, not-guilty findings, no-bills, and no-probable-cause findings — carry no waiting period for sealing. If your Nantucket County case ended in a dismissal, you can petition immediately. There is no fee to request sealing in Massachusetts.

Conviction sealing requires a waiting period measured from completion of the sentence (the disposition plus the end of any incarceration or custody): 3 years for a misdemeanor conviction and 7 years for a felony conviction. Sex offense convictions carry a 15-year wait. During that window, you cannot have any new convictions.

Expungement eligibility under §§ 100E-100U is narrower still. The offense must have occurred before your 21st birthday. The same 3-year misdemeanor / 7-year felony waiting period applies. You may have no more than two records total. Serious categories are excluded entirely: offenses causing death or serious bodily injury, sex offenses, firearms violations, OUI, restraining-order violations, and domestic assault. If your record falls into any of those categories, sealing — not expungement — is the available path.

You can self-petition without an attorney. The Petition to Seal form is available through the Massachusetts Trial Court. Bring it to the Nantucket County Courthouse clerk’s window; the clerk can confirm which form applies to your specific case type. If you qualify for an indigency waiver, filing costs are reduced or eliminated — ask the clerk about the waiver process at the time you file.

Attorney-assisted petitions are worth considering if your record involves multiple cases, if the eligibility question is close, or if you want help navigating the Commissioner of Probation’s process. The state’s lawyer search tool lists licensed Massachusetts attorneys by practice area. If you can’t afford private counsel, the Committee for Public Counsel Services may be able to help.

After a successful sealing, the public record disappears from MassCourts and from standard background checks. Law enforcement agencies retain access. CORI-authorized employers — those with specific statutory authorization — may see a notation that a sealed record exists, but not its contents. Expungement goes further: the record is destroyed, and you may legally answer “no” to most questions asking whether you have a criminal record.

Frequently asked questions about Nantucket County arrest records

How do I find out what arrest records exist under a specific name in Nantucket County?

Run a name search through the Massachusetts Trial Court docket portal — it covers Nantucket District Court criminal cases and shows charges, hearing dates, and dispositions for public records. For booking-side records not yet in the court system, call the Nantucket Police Department at (508) 228-1212 and ask about their records-request process. Keep in mind that sealed or expunged records won’t appear in either search.

Can a Nantucket County arrest record be sealed or expunged, and how long does it take?

Yes. Dismissed cases and not-guilty findings can be sealed immediately — no waiting period applies under M.G.L. c. 276, §§ 100A-100C. Conviction sealing requires 3 years after completing a misdemeanor sentence or 7 years after a felony sentence. Expungement under M.G.L. c. 276, §§ 100E-100U is available for offenses that occurred before age 21, subject to the same waiting periods and with no more than two records total — but serious offense categories are excluded. File the Petition to Seal at the Nantucket County Courthouse where the case was originally heard; there is no filing fee for sealing petitions.
