Before you begin — know the assets and liabilities
Before you file anything in Nantucket County, know exactly what is in the estate. The path you take depends on whether there is a will and on the value and type of the assets. Massachusetts offers voluntary administration for a small estate of personal property, informal probate for the ordinary uncontested case, and formal probate when there is a dispute or a defective will. These paths and their dollar thresholds are statewide and are explained on the Massachusetts state page; identify the estate first so you file the right petition once.
Identify every bank and credit-union account, retirement plan, brokerage holding, life-insurance policy, vehicle, and parcel of real property, along with every debt, before you go to the Registry. On Nantucket this matters for real estate in particular, because conveying a decedent's home can require a license to sell if the will grants no power of sale, and it requires clearing the Massachusetts estate tax lien at the Nantucket County Registry of Deeds. Sunset's asset-discovery work, searching more than 2,300 financial institutions, exists for this step.
Which court handles jurisdiction
The Nantucket Probate and Family Court serves all of Nantucket County, which is coextensive with the Town of Nantucket, the only consolidated town-county in Massachusetts. The county and the town are one and the same government, covering the island of Nantucket together with the smaller islands of Tuckernuck and Muskeget. Nantucket is a single community rather than a set of separate towns, and its named villages, including Madaket, Surfside, Polpis, Wauwinet, Miacomet, and Siasconset (commonly shortened to 'Sconset), all lie within that one town. There is one courthouse, at 16 Broad Street in Nantucket, and estates from every part of the island are filed there with the Registry of Probate. Because the county is a single island, filings can be made through eFileMA or by mail as well as in person at the Broad Street counter.
Venue for a decedent's estate is the county where the decedent was domiciled at death (MGL c. 190B, § 3-201). If the decedent lived on Nantucket, file in Nantucket County. If the decedent was not domiciled in Massachusetts but owned property in the county, venue is also proper here. A proceeding may be transferred to another county for cause or convenience (MGL c. 190B, § 1-303). Uncontested informal probate is decided by a MUPC Magistrate with no hearing; formal and contested matters go before a judge of the division. Probation matters for the division are handled by the Barnstable Probate and Family Court; this does not change probate venue, and every Nantucket County estate is still filed at the Broad Street Registry of Probate.
The jurisdiction process
- Gather the documents. Collect the original signed will (if any), a certified copy of the death certificate, the proposed personal representative's contact information and photo ID, the names and addresses of the heirs and devisees, and a list of the assets and debts with values. A personal representative named in a will was historically called an executor and one appointed without a will an administrator; Massachusetts now uses personal representative for both.
- Choose the path and the form. Massachusetts uses one statewide set of MPC forms in every division. File the Petition for Informal Probate (MPC 150) for the ordinary uncontested case, the Petition for Formal Adjudication (MPC 160) when there is a dispute or a defective will, or the Voluntary Administration Statement (MPC 170) for a qualifying small estate of personal property. The governing thresholds are statewide and are on the Massachusetts state page.
- File with the Registry of Probate in Nantucket. File at the counter at 16 Broad St., 2nd Floor, by mail to P.O. Box 1116, Nantucket, MA 02554, or through eFileMA (Odyssey File and Serve), which is available 24/7 and lets an off-island filer file without traveling. eFiling is available but not required.
- Pay the filing fee. The fee is uniform statewide: $390 for informal or formal probate ($375 plus a $15 surcharge) and $115 for voluntary administration ($100 plus a $15 surcharge), per the Probate and Family Court fee schedule on mass.gov, verified July 2026. Newspaper publication and deputy-sheriff service, where required, are separate costs paid outside the court. Tyler charges its own convenience fee for eFileMA filings.
- Give notice. Informal probate requires notice to interested persons and, where applicable, publication; formal probate proceeds by citation and order of notice issued by the court. The MPC forms include the notice and surviving-spouse/heirs companion forms.
- Attend the hearing only if one is set. Informal probate and informal appointment are allowed administratively by a MUPC Magistrate with no hearing; the Magistrate may act as early as seven days after death. Formal probate is heard by a judge. Remote hearing access is available; confirm arrangements with the Registry.
- Receive the Letters of Authority. On appointment the court issues Letters of Authority, the proof of the personal representative's authority to act. A certified copy from the Registry of Probate is what banks, transfer agents, and the Registry of Deeds rely on. Request enough certified copies for the institutions involved; additional Letters cost $25 each (mass.gov fee schedule, verified July 2026).
- Administer and close. Inventory and appraise the assets, pay valid claims in statutory priority, and account to the estate. A creditor's claim against the estate must generally be brought within one year after the date of death (MGL c. 190B, § 3-803). If the estate includes Nantucket real estate that must be sold, obtain a license to sell (MGL c. 202) where the will grants no power of sale, and clear the Massachusetts estate tax lien at the Nantucket County Registry of Deeds before conveying.
Forms and documents
Probate forms in Nantucket County

The load-bearing forms are the Petition for Informal Probate of a Will and/or Appointment of a Personal Representative (MPC 150), the Petition for Formal Probate of Will and/or Appointment of a Personal Representative (MPC 160), and the Voluntary Administration Statement (MPC 170), with common companions including the bond (MPC 801) and the surviving-spouse, children, and heirs-at-law form (MPC 162). The forms are published statewide on mass.gov and on the Trial Court forms portal.
In Nantucket County these forms are filed with the Registry of Probate at the Broad Street courthouse, by mail to the P.O. Box, or through eFileMA. For questions about local intake or what the Registry needs, call the Registry of Probate at (508) 228-2669.

Scenarios
| Situation | Likely path in Nantucket County | Where Sunset helps |
|---|---|---|
| Surviving spouse, co-owned home | If the Nantucket home was held in joint tenancy or as tenants by the entirety, it passes to the surviving spouse outside probate by recording a death certificate and affidavit at the Nantucket County Registry of Deeds. If the home was in the decedent's sole name and there is a will, the spouse files the Petition for Informal Probate (MPC 150) with the Registry of Probate in Nantucket and, once appointed, receives Letters of Authority. | Asset discovery to confirm how title is held. Packet generation for the MPC 150 filing. Guidance on recording the survivorship documents at the Registry of Deeds. |
| Out-of-state adult child, small estate | For a qualifying small estate of personal property with no real estate, the child can file the Voluntary Administration Statement (MPC 170), which is decided without a hearing. For a larger estate, the child files informal probate (MPC 150). Either can be filed through eFileMA or by mail to the Nantucket P.O. Box, so an off-island filer can proceed without traveling to the island. | Asset discovery to confirm the estate qualifies. Packet generation for MPC 170 or MPC 150, prepared so an out-of-state filer can proceed through eFileMA or by mail. |
| Parent settling a predeceased child's estate, home must be sold | The parent files informal or formal probate with the Registry of Probate in Nantucket and, once issued Letters of Authority, can act for the estate. Because the Nantucket home must be sold, the personal representative obtains a license to sell (MGL c. 202) where the will grants no power of sale, and clears the Massachusetts estate tax lien at the Nantucket County Registry of Deeds before conveying. | Asset discovery for the child's accounts and property. Packet generation for the probate filing and the license-to-sell paperwork. Attorney referral if the sale or an heir dispute turns contested. |

When to hire an attorney
Many Nantucket County estates are uncontested and can be handled without an attorney: a qualifying small estate of personal property moves by voluntary administration (MPC 170) without a hearing, and an ordinary case moves by informal probate (MPC 150) before a MUPC Magistrate. Consider counsel when the estate holds Nantucket real estate that must be sold and the will grants no power of sale, when a will contest or heir dispute is likely, when the estate is insolvent or a formal accounting is demanded, or when the estate includes a business interest or out-of-state property. An attorney can also manage a formal probate before a judge and any remote appearances. Sunset can connect families to a vetted Massachusetts probate attorney serving Nantucket County.
