A will does not need to be notarized in Massachusetts. Under state law, a will is valid as long as it is in writing, signed by the person making it, and signed by two witnesses. A notary only enters the picture if you choose to add a self-proving affidavit, which is an optional attachment that makes probate easier later. Skipping the affidavit does not affect whether your will is legally binding.
What Massachusetts Actually Requires for a Valid Will
Three requirements, all in the same statute, control whether a Massachusetts will holds up.1General Court of Massachusetts. Massachusetts General Laws Chapter 190B, Section 2-502 – Execution of Wills
- The will is in writing. Oral wills are not recognized in any circumstance.
- The testator signs it. If the testator physically cannot sign, another person may sign for them, but only in the testator’s conscious presence and at the testator’s explicit direction.
- At least two witnesses sign, having either watched the testator sign the will or heard the testator acknowledge the signature already on it.
The testator also has to be at least 18 and of sound mind.2Mass.gov. Massachusetts General Laws c.190B 2-501 – Who May Make Will Sound mind means the person understands what they own, who their family and likely heirs are, and what signing a will actually does. Serious illness or advanced age does not, by itself, defeat capacity.
A notary’s signature or seal is not on that list. The will itself is never required to be notarized. That is the beginning and end of the strict answer.
Where Notarization Does Come In: The Self-Proving Affidavit
When a will enters probate, the court has to confirm it was properly signed and witnessed. Without extra paperwork, that usually means finding the original witnesses and having them testify. If a witness has moved, become incapacitated, or died, that step gets slow and expensive.
A self-proving affidavit fixes that. 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 the signing formalities were followed.3General Court of Massachusetts. Massachusetts General Laws Chapter 190B, Section 2-504 – Self-Proved Will When the probate court sees the affidavit, it accepts the will’s execution as valid without live witness testimony. The document essentially proves itself.
The affidavit is not required. Your will is just as binding without it. It is, however, the single easiest step you can take at signing to spare your family delays and legal costs later. The only added expense is the notary’s fee, and Massachusetts sets no statutory cap on what a notary charges for this kind of act.
How to Add a Self-Proving Affidavit
Massachusetts allows two paths.3General Court of Massachusetts. Massachusetts General Laws Chapter 190B, Section 2-504 – Self-Proved Will
Sign Everything at Once
This is the usual approach. You and both witnesses meet in front of a notary. You sign the will, then all three of you sign the affidavit. In the affidavit, you swear you are signing willingly, are at least 18, are of sound mind, and are not under undue influence. The witnesses swear they watched you sign and believe you meet those same conditions. The notary signs, applies the official seal, and it is done.
Add the Affidavit Later
If you already have a properly witnessed will but never did an affidavit, you can add one. You and the same witnesses appear together before a notary, acknowledge the will, and sign a separate affidavit. The wording differs slightly because everyone is confirming what happened earlier rather than in real time, but the legal effect is the same.
Either way, attach the affidavit to the will. An affidavit that isn’t clearly connected to the document it references invites confusion at probate.
Choosing Witnesses Carefully
Massachusetts requires anyone “generally competent to be a witness” to serve.4Mass.gov. Massachusetts General Laws c.190B 2-505 – Who May Witness That generally means an adult who understands what they are watching. The statute does not set an explicit age floor for witnesses the way it does for testators, but using adults over 18 is the safe practice.
The bigger concern is who those witnesses are. A beneficiary can technically serve as a witness, but doing so creates a real problem: the beneficiary’s inheritance is void unless two additional disinterested witnesses also signed the will, or the beneficiary-witness can prove in court that the gift was not the product of fraud or undue influence. The same rule extends to the witness’s spouse. The clean fix is to use two witnesses who inherit nothing under the will. A neighbor, a coworker, or a receptionist at your attorney’s office all work.
Handwritten Wills and the Missing Safety Valve
People sometimes assume a will in the testator’s own handwriting bypasses the witness rules. In Massachusetts it does not. Unwitnessed holographic wills are not recognized. A handwritten will has to meet the same requirements as a typed one: signed by the testator and signed by two witnesses.
Massachusetts also reserved Section 2-503 of the Uniform Probate Code, which would have let courts forgive technical execution errors when there was clear evidence the testator intended the document to be their will.5Mass.gov. MGL 190B, Article II – Intestacy, Wills and Donative Transfers The legislature declined to adopt that provision. If your will lacks two witness signatures, no amount of evidence about your intent will save it. The signing ceremony has to be done right the first time.
Updating or Revoking a Will
A valid will only helps if it is the current one. Massachusetts allows two ways to revoke.6General Court of Massachusetts. Massachusetts General Laws Chapter 190B, Section 2-507 – Revocation by Writing or by Act The first is to execute a new will that either expressly revokes the old one or is inconsistent enough with it that both cannot stand. The second is a physical act: burning, tearing, canceling, or destroying the document with the intent to revoke it. Another person can do the physical act, but only in the testator’s conscious presence and at the testator’s direction.
If the new will fully disposes of your estate, courts presume you meant it to replace the old one. If the new will covers only part of your estate, courts presume you meant it to supplement the earlier will, and the old will stays in force wherever the two do not conflict. Writing a partial new will without expressly revoking the old one is a common way to end up with two partially valid documents and a family fight.
For smaller changes, a codicil works. A codicil is an amendment to the existing will, and it has to meet the same execution requirements: signed by you and witnessed by two people. Reference the original will by date, state clearly what it changes, and store the two documents together.
A change in circumstances alone does not revoke a will in Massachusetts, with limited exceptions tied to divorce and marriage.7General Court of Massachusetts. Massachusetts General Laws Chapter 190B, Section 2-508 – Revocation by Change of Circumstances Divorce, for example, generally revokes provisions favoring a former spouse. Having a new child, buying a house, or selling major assets does not update the will on its own. That part is on you.
