Overview

Nantucket County is located in Massachusetts with a population of approximately 14,670. The Nantucket Probate and Family Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Massachusetts probate is governed by the Massachusetts Uniform Probate Code (MUPC). The process begins with filing a Petition for Formal or Informal Probate (Form MPC 150) to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

For smaller estates, Massachusetts offers a simplified procedure known as Voluntary Administration. This is available if the estate consists entirely of personal property valued at $25,000 or less (excluding the value of one car) and there is no real estate requiring probate.

Massachusetts does not have a statutory fee schedule for attorneys or executors based on a percentage of the estate; fees must be reasonable based on services rendered.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Voluntary Administration: For estates valued at $25,000 or less (excluding one vehicle) with no real estate. This is a simplified process filed using the Voluntary Administration Statement (Form MPC 170).
  • Joint Tenancy/Survivorship: Assets held jointly with rights of survivorship pass automatically to the survivor.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal or informal probate is needed, file a Petition for Probate (Form MPC 150) with the Nantucket Probate and Family Court. Include:

  • Petition for Probate (MPC 150)
  • Original will and codicils (if any)
  • Certified copy of the death certificate
  • Filing fee ($390 for full probate)
  • Bond (MPC 480)
  • Military Affidavit (MPC 470)

E-filing is available for some case types in Massachusetts, but many initial probate petitions are still filed by mail or in person.

Step 3: Provide Notice

After filing, you must:

  • Mail notice (Citation) to all heirs, beneficiaries, and interested parties at least 14 days before the hearing (or as directed by the citation).
  • Publish notice in a newspaper of general circulation in Nantucket County, typically The Inquirer and Mirror, if required by the court or for formal probate.

Step 4: Attend the Hearing

For formal probate, the court will schedule a hearing on the petition. At the hearing, the judge reviews the petition and, if approved, issues the Decree and Order and Letters of Authority. Informal probate may be processed administratively by a magistrate without a hearing if uncontested.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors (creditors have 1 year from the date of death to file claims)
  • Inventory and appraise all estate assets within 3 months
  • Pay valid creditor claims and estate expenses
  • File federal and state tax returns as needed (including MA estate tax if applicable)
  • Distribute assets to beneficiaries
  • File a final accounting and petition to close the estate
