Massachusetts Estate Planning and Probate Law: Wills, Trusts, and Administration

Massachusetts estate planning and probate law governs how residents structure the transfer of assets during life and at death, and how courts supervise that process. The field spans the drafting of wills and trusts, the appointment of fiduciaries, the administration of decedents' estates, and the resolution of disputes over inheritance. For residents, attorneys, and financial professionals operating in the Commonwealth, understanding this legal framework is foundational to advising clients and navigating the Massachusetts Probate and Family Court.

Definition and scope

Massachusetts estate planning and probate law draws its statutory authority primarily from the Massachusetts Uniform Probate Code (MUPC), codified at Massachusetts General Laws (M.G.L.) Chapter 190B. The MUPC, which Massachusetts adopted effective March 31, 2012, replaced the older probate framework and modernized intestacy rules, will formalities, and trust administration standards.

Scope of coverage under M.G.L. c. 190B includes:

• Intestate succession (asset distribution when a person dies without a valid will)
• Formal and informal probate of wills
• Appointment and removal of personal representatives and conservators
• Guardianship of incapacitated individuals
• Trust formation, modification, and termination
• Powers of attorney and health care proxies (the latter governed separately by M.G.L. c. 201D)

Scope limitations and what is not covered: This page addresses Massachusetts state law exclusively. Federal estate tax rules — administered by the Internal Revenue Service under the Internal Revenue Code — operate in parallel and are not governed by M.G.L. c. 190B. Assets held in certain non-probate forms, such as retirement accounts with named beneficiaries or jointly held property with right of survivorship, pass outside the probate estate and are subject to distinct legal rules. Interstate and international estates involving domicile in more than one jurisdiction require conflict-of-laws analysis that extends beyond Massachusetts statutes alone. For the broader regulatory context for Massachusetts legal system, including how state and federal law interact, readers should consult authoritative sources addressing jurisdictional boundaries.

The Massachusetts Probate and Family Court — one of seven Trial Court departments — holds exclusive jurisdiction over probate matters across 14 divisions (Massachusetts Trial Court).

How it works

Estate administration under M.G.L. c. 190B follows a structured sequence. The MUPC creates two primary tracks:

1. Informal probate — An application is filed with the Register of Probate without a judicial hearing. A personal representative is appointed administratively. This track is available when no will contest is anticipated and the estate is not complex.
2. Formal probate — Requires a judicial proceeding before a Probate and Family Court judge. Used when will validity is disputed, interested parties are unknown or unlocatable, or the decedent's domicile is contested.

The administration process, whether informal or formal, proceeds through these phases:

1. Filing the petition or application — Submitted to the Probate and Family Court division in the county of the decedent's last domicile.
2. Appointment of the personal representative — The court or Register issues Letters Testamentary (if a will exists) or Letters of Administration (intestate estates).
3. Notice to interested parties — Heirs, devisees, and creditors must receive notice per M.G.L. c. 190B, §3-801 through §3-805. Creditors have a statutory claim period of one year from death.
4. Inventory and appraisal — The personal representative files an inventory of probate assets within three months of appointment.
5. Payment of debts, taxes, and expenses — Massachusetts imposes its own estate tax on estates exceeding $2 million (M.G.L. c. 65C), administered by the Massachusetts Department of Revenue. The $2 million threshold applies to the gross estate value for Massachusetts purposes, which differs from the federal exemption.
6. Distribution — Remaining assets are distributed to devisees under the will or to heirs under intestacy statutes.

Trusts — inter vivos (living) trusts and testamentary trusts — are governed by M.G.L. c. 203E, the Massachusetts Uniform Trust Code (MUTC), effective July 8, 2012. Trusts allow asset transfer without probate court involvement, subject to the trustee's fiduciary obligations.

Common scenarios

The estate planning and probate landscape in Massachusetts encompasses distinct factual patterns that drive different legal pathways:

Testate estate (will exists): A decedent leaves a will signed by 2 witnesses per M.G.L. c. 190B, §2-502. The will is offered for probate, and a personal representative administers the estate through formal or informal proceedings.

Intestate estate (no will): Assets pass to heirs under M.G.L. c. 190B, §2-101 through §2-114. The Commonwealth's intestacy scheme prioritizes surviving spouses and descendants, with specific fractional shares defined by statute.

Revocable living trust administration: A settlor transfers assets to a revocable trust during life, naming a successor trustee to manage and distribute assets at death outside of probate. The MUTC governs trustee duties, accounting obligations, and beneficiary rights.

Will contest: An interested party challenges a will's validity on grounds of lack of testamentary capacity, undue influence, fraud, or improper execution. These proceedings require formal probate before a Probate and Family Court judge.

Conservatorship and guardianship: When an individual cannot manage property or personal decisions, the Probate and Family Court appoints a conservator (for financial matters) or guardian (for personal matters) under M.G.L. c. 190B, Article V.

Elective share: A surviving spouse who is disinherited may claim an elective share of the augmented estate under M.G.L. c. 190B, §2-202, a protection that modernized surviving spouse rights under the MUPC.

Decision boundaries

The selection of estate planning instruments and probate tracks depends on asset type, estate complexity, family structure, and tax exposure. The following distinctions govern professional practice and client outcomes:

Probate vs. non-probate assets: Probate assets — individually owned property without a beneficiary designation — pass through the court-supervised process. Non-probate assets (joint tenancy, POD accounts, IRAs, life insurance with named beneficiaries) transfer automatically and are not subject to Probate and Family Court jurisdiction.

Will vs. revocable trust as primary instrument: A will requires probate; a fully funded revocable trust does not. For Massachusetts residents with real property in multiple states, a revocable trust avoids ancillary probate proceedings in other jurisdictions. However, a pour-over will is typically paired with a trust to capture unfunded assets, meaning some probate exposure may remain.

Massachusetts estate tax threshold: Estates valued above $2 million (M.G.L. c. 65C) are subject to Massachusetts estate tax at graduated rates up to 16%, administered by the Massachusetts Department of Revenue. Federal estate tax under IRC §2001 applies at a substantially higher exemption threshold, creating a planning gap that drives trust and gifting strategies specific to Massachusetts residents.

Fiduciary selection — executor vs. trustee: Personal representatives (executors) operate under court supervision; trustees of private trusts operate under the MUTC with beneficiary oversight rather than automatic court involvement. The scope of fiduciary duties, accounting requirements, and removal procedures differ materially between the two roles.

Formal vs. informal probate: Informal probate is faster and less expensive but is unavailable when any interested party objects or when the will's validity is in question. Formal proceedings provide judicial resolution but extend the administration timeline and increase costs.
