Statutory Authority

Wills

Massachusetts General Laws (MGL) Chapter 190B, the Massachusetts Uniform Probate Code (§§2-501 to 2-505).

Trusts

Massachusetts General Laws (MGL) Chapter 203E, the Massachusetts Uniform Trust Code.

Massachusetts Will Requirements

A Massachusetts Last Will and Testament should include:

  • Age and Capacity: Testator must be at least 18 years old and of sound mind, meaning they understand the nature of the will, their property, and intended beneficiaries (§2-501)
  • Format: Must be in writing; oral wills are generally not recognized except for soldiers or mariners under specific circumstances (§2-502)
  • Signature: Must be signed by the testator or by another person at their direction in their conscious presence (§2-502)
  • Witnesses: Requires signatures from two competent witnesses, who must witness the signing or acknowledgment of the will (§2-502)

Interested Witnesses

Massachusetts allows witnesses to be beneficiaries under the will, but their inheritance may be limited to what they would have received under intestacy laws if there aren’t at least two other disinterested witnesses.

Self-Proved Wills

A notarized affidavit can make a will self-proved in Massachusetts, simplifying probate by eliminating the need for witness testimony (§2-504). This affidavit:

  • Must be signed by the testator and witnesses
  • Must be notarized
  • Can be executed at the time of will signing or later
  • Streamlines the probate process by eliminating the need to locate witnesses

Amendment, Revision, and Revocation of Massachusetts Wills

Revoking a Massachusetts Will

Massachusetts wills can be revoked through:

  1. Executing a new will that explicitly revokes the prior one
  2. Physical destruction (burning, tearing, canceling, obliterating, or destroying) of the will with intent to revoke (§2-507)

Automatic Revocation by Divorce

In Massachusetts, provisions favoring a former spouse are automatically revoked upon divorce (§2-508). This includes property dispositions and appointments of the former spouse as executor or trustee.

After-Born/Omitted Children

If a child is born after a will is executed (pretermitted heir), they receive an intestate share unless explicitly disinherited (§2-603). This protects children from unintentional disinheritance.

Holographic and Oral Wills

Holographic Wills

Massachusetts does not recognize holographic (handwritten) wills. All valid wills must comply with the formal witness requirements (§2-502). No matter how clearly written or signed, a handwritten will without proper witnesses is not valid in Massachusetts.

Oral Wills

Oral (nuncupative) wills are recognized in Massachusetts only in very limited circumstances. They are valid only for:

  • Soldiers in active military service
  • Mariners at sea
  • Only for disposition of personal property (not real estate)
  • Subject to strict proof requirements

Massachusetts Trust Requirements

Trusts in Massachusetts are governed by the Massachusetts Uniform Trust Code (MGL Chapter 203E).

Requirements for a Valid Massachusetts Trust

For a trust to be valid under Massachusetts law:

  • The settlor must have capacity (same standard as for wills) and express intent to create a trust (§203E-402)
  • The trust must have lawful purposes and identifiable beneficiaries (§203E-404)
  • Charitable trusts and pet trusts are exceptions to the definite beneficiary requirement
  • The trust property must be sufficiently identified

Under Massachusetts law, trusts are revocable unless explicitly stated otherwise (§203E-602).

Trustee Responsibilities

Trustees in Massachusetts must:

  • Act in good faith and adhere to fiduciary responsibilities (§203E-801)
  • Follow the “prudent investor rule” unless modified by the trust terms
  • Manage trust assets for the benefit of beneficiaries
  • Maintain adequate records and provide accountings when required

Trust Creation Methods

Massachusetts trusts can come into existence through:

  • Transfer of property to a trustee during life
  • Declaration that the settlor holds identified property as trustee
  • Exercise of a power of appointment in favor of a trustee
  • Transfer of property at death through a testamentary trust

Special Considerations

Estate Taxes

Massachusetts imposes its own estate tax on estates valued over $2 million, with rates up to 16%. This is one of the lowest estate tax thresholds in the country. The federal estate tax applies only to estates exceeding $13.99 million (2025 threshold).

This means even moderate-sized estates in Massachusetts may face state estate tax liability, making tax planning an essential component of Massachusetts estate planning.

Simplified Probate Options

Massachusetts offers streamlined procedures for smaller estates:

Small Estate Procedure

Eligibility:

  • Estates valued under $25,000 (excluding the value of a vehicle) may qualify for an expedited small estate affidavit process

Process:

  • A voluntary personal representative can file an affidavit
  • No formal court proceedings required
  • Simplified forms and reduced waiting periods

Informal Probate

Massachusetts offers an informal probate process for uncontested estates that requires less court supervision.

Non-Probate Transfers

Massachusetts offers multiple options for transferring assets outside of probate:

Beneficiary Designations

  • POD (payable-on-death): Available for bank accounts
  • TOD (transfer-on-death): Available for investment accounts
  • Other assets with beneficiary designations:
    • Life insurance policies
    • Retirement accounts (401(k)s, IRAs)

Joint Ownership

  • Joint tenancy with right of survivorship: Property automatically transfers to surviving owners
  • Tenancy by the entirety: Special form of ownership available only to married couples in Massachusetts, offering both automatic transfer at death and some creditor protection

Homestead Protections

Massachusetts offers significant homestead protection for primary residences. Through a homestead declaration, homeowners can protect up to $500,000 of their primary residence’s equity from creditors. This protection:

  • Must be formally declared through a recorded homestead declaration
  • Protects the home from many types of creditor claims
  • Continues to benefit surviving family members
  • Works alongside (not instead of) proper estate planning

Spousal Shares

Elective Share

Massachusetts provides protections for surviving spouses through an elective share. A surviving spouse can claim:

  • One-third of the deceased spouse’s personal and real property if the deceased left descendants
  • One-half of the estate if the deceased left kindred but no descendants
  • The entire estate if the deceased left neither descendants nor kindred

Intestate Succession

If a Massachusetts resident dies without a will:

  • The surviving spouse receives the entire estate if there are no children or parents of the deceased
  • If there are surviving children who are also children of the surviving spouse, and the spouse has no other descendants, the spouse receives the entire estate
  • In other scenarios, the estate is divided between the spouse and other heirs according to statutory formulas

Frequently Asked Questions

Do I need a lawyer to create a will in Massachusetts?

While not legally required, professional legal assistance ensures your will complies with Massachusetts’ strict requirements and helps avoid potential issues during probate.

What happens if I die without a will in Massachusetts?

Your assets will be distributed according to Massachusetts intestacy laws, which prioritize spouses and children but may not align with your personal wishes.

Are handwritten wills valid in Massachusetts?

No, Massachusetts does not recognize holographic (handwritten) wills. All valid wills must be properly witnessed according to statutory requirements.

What makes Massachusetts’ estate tax unique?

Massachusetts has one of the lowest estate tax thresholds in the country at $2 million, with rates up to 16%. This means even moderate-sized estates may face significant state estate tax liability.

How does Massachusetts protect children from disinheritance?

Pretermitted heirs (children born or adopted after will execution) receive an intestate share unless explicitly excluded in the will.

What is unique about Massachusetts’ spousal elective share?

A surviving spouse can claim one-third to the entire estate depending on whether the deceased left descendants or other relatives, regardless of what the will provides.

Can I use a trust to avoid probate in Massachusetts?

Yes, assets properly transferred to a living trust during your lifetime avoid probate upon your death, which can be especially valuable given the public nature of probate in Massachusetts.

What is Massachusetts’ small estate procedure?

Estates valued under $25,000 (excluding vehicles) qualify for an expedited small estate affidavit process that simplifies asset transfer without full probate proceedings.

Conclusion

Creating a will or trust in Massachusetts does not have to be difficult or intimidating. However, Massachusetts presents unique considerations, especially regarding estate taxes, strict will requirements, and homestead protections. Certain circumstances—like second marriages, stepchildren, aging parents, special needs beneficiaries, and business interests—can add complexity and result in unforeseen consequences. Given Massachusetts’ low estate tax threshold, even modest estates benefit from comprehensive planning. Whenever any out-of-the-ordinary issues are present, it’s advisable to consult with an experienced attorney familiar with Massachusetts’ specific laws.
