Does a Will Need to Be Notarized in Massachusetts?

A will does not need to be notarized in Massachusetts. State law makes a will valid as long as it is in writing, signed by the person making it, and signed by two witnesses.1Justia Law. Massachusetts General Laws Chapter 190B, Section 2-502 – Execution of Wills A notary is not on that list. Notarization enters the picture only if you choose to attach a self-proving affidavit, an optional add-on that speeds up probate later. Skipping the affidavit does not weaken your will; adding one is cheap protection for your family.

What Massachusetts Actually Requires

Three things make a will valid under Massachusetts General Laws Chapter 190B, Section 2-502. Each one matters, and missing any single piece can sink the whole document.

You also have to be at least 18 and of sound mind.3Mass.gov. Massachusetts General Laws c.190B 2-501 – Who May Make Will Sound mind means you understand what property you own, who your family and likely heirs are, and what signing a will does. Serious illness or old age does not automatically disqualify you.

Notice what is not on the list: a notary’s signature or seal. The will document itself never needs one.

Why Notaries Come Up at All: The Self-Proving Affidavit

When a will enters probate, the court has to confirm it was signed and witnessed properly. Without a self-proving affidavit, that usually means contacting the original witnesses so they can testify about what they saw. If a witness has died, moved out of state, or become incapacitated by the time you die, that process becomes slow and expensive.

A self-proving affidavit removes that step. It is a sworn statement, signed by the testator and both witnesses in front of a notary public or other officer authorized to administer oaths, confirming that all the signing formalities were followed.4General Court of Massachusetts. Massachusetts General Laws Chapter 190B, Section 2-504 – Self-Proved Will When the probate court sees the affidavit, it accepts the execution as valid without calling witnesses. The will proves itself.

The affidavit is optional. Your will is just as legally binding without one. But it is the single easiest step you can take during signing to spare your family trouble later, and the cost is usually just a notary’s fee for one session. Massachusetts does not set a statutory cap on notary fees for this type of act.

How to Add a Self-Proving Affidavit

Massachusetts law gives you two routes under Section 2-504.4General Court of Massachusetts. Massachusetts General Laws Chapter 190B, Section 2-504 – Self-Proved Will

Sign Everything at Once

This is the standard approach. You and both witnesses gather in front of a notary public. You sign the will, then all three of you sign the self-proving affidavit. In the affidavit, you declare under oath that you are signing willingly, are at least 18, are of sound mind, and are under no undue influence. The witnesses swear they watched you sign and believe you meet those same conditions. The notary signs, applies the official seal, and the affidavit is complete.

Add the Affidavit to a Will You Already Signed

If you have a properly witnessed will but no affidavit, you can add one later. You and the same original witnesses must appear together before a notary, acknowledge the will, and sign a separate affidavit form. The language differs slightly because everyone is confirming a past event rather than a current one, but the legal effect is identical.

Either way, the affidavit has to be physically attached to the will. A free-floating affidavit that is not clearly tied to the document it references causes problems at probate.

Pick Witnesses Who Do Not Inherit

Massachusetts allows anyone “generally competent to be a witness” to sign.5Mass.gov. Massachusetts General Laws c.190B 2-505 – Who May Witness In practice that means an adult who understands what they are watching. The statute does not spell out a minimum age for witnesses the way it does for testators, so sticking with adults over 18 is the safe choice.

The bigger issue is choosing witnesses who do not inherit anything under the will. Massachusetts will not automatically void a will signed by a beneficiary-witness, but it creates a real problem for that beneficiary. Their inheritance is void unless two additional disinterested witnesses also signed, or the beneficiary-witness can prove in court that the gift was not the product of fraud or undue influence. The rule reaches the witness’s spouse too. The simple fix is to pick two people who get nothing in the will. A neighbor, a coworker, or a receptionist at your attorney’s office all work fine.

What Massachusetts Does Not Allow

If you have heard about shortcuts available in other states, assume they do not exist here.

Massachusetts does not recognize unwitnessed handwritten (holographic) wills. Some states let a will written entirely in the testator’s own handwriting skip the witness requirement. Massachusetts does not. A handwritten will is valid only if it meets the same requirements as a typed one: signed by the testator and signed by two witnesses.2General Court of Massachusetts. Massachusetts General Laws Chapter 190B, Section 2-502 – Execution of Wills

Oral wills are never valid, regardless of the circumstances.

Massachusetts also declined to adopt Section 2-503 of the Uniform Probate Code, which would have allowed courts to forgive technical execution errors when there is clear evidence the testator intended the document as their will.6Mass.gov. MGL 190B, Article II – Intestacy, Wills and Donative Transfers The legislature left that safety valve out. If your will is missing a witness signature, no amount of evidence about what you meant will rescue it. Getting the signing right the first time is not optional in Massachusetts.

So, to come back to the original question: no, your Massachusetts will does not need to be notarized. Two witnesses and your signature on a written document are what make it legally binding. A notary enters the picture only when you decide to add the self-proving affidavit, and in almost every case, you should.
