Will requirements in Massachusetts

To make a valid will in Massachusetts, you must be at least 18 and of sound mind, and you must sign it in front of two witnesses. No notary is required to make the will itself valid, though most people add a notarized self-proving affidavit so the court does not need to locate witnesses later. Massachusetts does not recognize a handwritten will that lacks two witnesses.

Who can make a will in Massachusetts

Massachusetts asks two things of you: that you are at least 18, and that you are of sound mind when you sign. Sound mind is a practical standard, not a medical one. It means you understand what you own, who your close family is, and that the document in front of you is your will.

Signing your will in Massachusetts

  1. You sign

    You sign the will yourself, or direct someone else to sign it for you in your conscious presence and at your direction.

  2. Two witnesses sign

    Two witnesses sign after watching you sign, or after you acknowledge that the signature or the will is yours. Choose adults who inherit nothing under it.

  3. The affidavit

    Optional but worth doing: a self-proving affidavit, sworn by you and your witnesses before a notary, so the court can later accept the will without locating anyone who was in the room.

Handwritten and electronic wills

Massachusetts does not recognize a holographic will: a page written and signed only in your own hand, without witnesses, carries no legal weight here, however clearly it states your wishes. Its execution statute requires two witnesses for every will and has no separate provision for an unwitnessed handwritten one. Massachusetts has not authorized electronic wills either. What eventually reaches your executor and the probate court is paper, signed in ink by you and two witnesses. That is exactly how Myend’s Last Will works everywhere: you build it online, then print it and sign it with your witnesses, the paper form every state accepts.

Property and your spouse

Massachusetts is a common-law property state: what you earn and hold in your own name is yours to leave, not automatically split with your spouse the way it would be in a community property state. But a will cannot fully disinherit a spouse here. Under the state’s elective share, a surviving spouse who files a claim within six months of probate can take one third of the personal and real property if you left children or their descendants, or twenty-five thousand dollars plus half of what remains if you left no children but other kindred survive you. A further limit is built into the statute itself: once the spouse’s share would be worth more than twenty-five thousand dollars, the amount above that line is not handed over outright. The spouse instead receives only the income from it for life, a life estate, while the underlying property eventually passes as your will directs.

Your executor

Massachusetts calls the person who carries out your will the executor. You can name almost any capable adult, whether or not they live in Massachusetts; the state does not require an in-state resident or an agent to receive papers on an out-of-state executor’s behalf, a lighter rule than some of its New England neighbors apply. New to the role? Start with what an executor actually does.

If someone challenges the will

Massachusetts takes a penalty clause in a will seriously and enforces it largely as written. If your will disinherits anyone who challenges it and they contest anyway and lose, Massachusetts courts will generally hold that provision against them. When the state adopted its own version of the modern probate code, it left out a default many other states kept: an exception that spares a challenger who had probable cause to contest. Massachusetts’s statute carries no such exception, which makes a penalty clause here a firmer deterrent than in most states.

If you do not make a will

Without a will, Massachusetts probate court works through a fixed sequence of relatives to decide who inherits, a sequence that has no way of knowing who you actually wanted to provide for. For blended families, unmarried partners, and close friends, that default order rarely matches real life. A valid will is how you replace the state’s sequence with your own decisions. See what happens if you die without a will.

What is different about Massachusetts

Twice, when Massachusetts wrote its own version of the modern probate code, it chose the stricter path: no exception for a will in your own handwriting, and none for a challenge brought in good faith either.

Many states that adopted a version of the Uniform Probate Code picked up two of its optional safety valves along the way: a carve-out that honors an unwitnessed will if it is entirely in the testator’s own hand, and a rule that will not enforce a no-contest clause against someone who had probable cause to challenge. Massachusetts left both out. Its execution statute recognizes only a will signed by two witnesses, with no separate holographic provision, and its penalty-clause statute enforces a no-contest clause as written, without the probable-cause exception several neighboring states carry.

The same older, careful instinct shows up in how Massachusetts protects a spouse. A surviving spouse who files a claim within six months of probate can take one third of the estate if you left children, or twenty-five thousand dollars plus half of what remains if you did not (MGL c.191 § 15). Once that share is worth more than twenty-five thousand dollars, the amount above it does not pass outright: the spouse receives only the income from it for life, while the property itself eventually goes where your will directs. Most states replaced this kind of life-estate structure decades ago with a flat percentage of the estate. Massachusetts kept it.

Common questions

Does a will have to be notarized in Massachusetts?
No. A Massachusetts will is valid once you and two witnesses have signed. Where a notary helps is proof rather than validity: the self-proving affidavit, sworn in front of one, lets the probate court accept the will on the paperwork alone instead of asking anyone to confirm what happened at the signing. Massachusetts offers that as a choice, not a duty.
How many witnesses does a Massachusetts will need?
Two. They must watch you sign, or hear you acknowledge that the signature or the will is yours, before adding their own signatures in your presence.
Is a handwritten will legal in Massachusetts?
No. Massachusetts’s execution statute recognizes only a will signed by two witnesses, with no separate provision for a page written and signed in your own hand alone.
Can I make my will online in Massachusetts?
You can prepare it online. Massachusetts has not authorized electronic wills, so the document you actually sign is paper, witnessed by two people, and that is exactly what Myend prepares for a Massachusetts will.
What is a self-proving affidavit, and do I need one in Massachusetts?
It is a sworn statement, signed by you and your witnesses before a notary, that lets the court accept your will later without locating anyone who was in the room. Massachusetts offers it as an optional add-on, not a requirement.
Can I disinherit my spouse in Massachusetts?
Not fully with a will alone. A surviving spouse who files a claim within six months of probate can take one third of the estate if you left children, or twenty-five thousand dollars plus half of what remains if you did not. Once that share passes twenty-five thousand dollars in value, the excess comes as a life estate rather than outright ownership.
Can my executor live outside Massachusetts?
Yes. Massachusetts does not require an executor to live in the state or to appoint anyone locally to receive papers, a lighter rule than some of its New England neighbors apply.
What happens if I die without a will in Massachusetts?
Probate court works through a fixed sequence of relatives, a sequence that has no way of knowing who you actually wanted to provide for.
