A family in Brooklyn calls my office. Their father recently passed, and they found his will tucked away in a desk drawer. It’s signed, dated, and bears the official stamp and signature of a notary public. They feel a sense of relief, believing everything is in order. But when they show me the document, I have to point out a critical—and potentially devastating—omission: there are no witness signatures.
This is one of the most persistent and dangerous misconceptions I encounter in my practice. People assume that a notary’s seal makes a legal document official. For deeds and contracts, that’s often true. For a New York will, it is absolutely not. The notary’s role is important, but it is not a substitute for the strict legal requirements of execution.
The Two Witnesses: New York’s Unyielding Requirement
The validity of a will is not a matter of suggestion; it is a matter of statute. Specifically, New York’s Estates, Powers and Trusts Law (EPTL) § 3-2.1 dictates precisely how a will must be executed. The law is unforgiving on this point. For a will to be admitted to probate by the Surrogate’s Court, it must be:
- In writing and signed at the end by the person making the will (the testator).
- Signed in the presence of at least two attesting witnesses, or the testator must acknowledge their signature to each witness separately.
- The testator must declare to the witnesses that the document they are signing is, in fact, their will. This is called “publication.”
- The two witnesses must sign their names at the end of the will within 30 days of each other.
Notice what’s missing from that list? A notary. A will signed by a testator and two witnesses is perfectly valid without a notary’s involvement. Conversely, a will signed only by the testator and a notary is invalid. The law prioritizes the testimony of impartial observers over the seal of a commissioned officer.
The logic is rooted in preventing fraud and undue influence. Witnesses can attest not only to the signature but to the testator’s state of mind—that they appeared competent and were acting of their own free will. A notary only verifies identity and the fact of a signature.
So, Why Use a Notary at All? The Self-Proving Affidavit
If a notary isn’t required to make a will valid, why do we use one in nearly every will execution ceremony at my firm? The answer lies in a separate, but attached, document: the self-proving affidavit.
This affidavit is a sworn statement that the testator and the witnesses sign in front of a notary public. In it, they swear under oath that all the formalities required by EPTL § 3-2.1 were followed on the day the will was signed. The notary then notarizes those signatures.
The power of this simple document is immense. It creates a legal presumption that the will was properly executed. When the will is later presented to the Surrogate’s Court, the court can accept it without needing to track down the original witnesses—who may have moved, passed away, or forgotten the details years later—to provide testimony. It streamlines the probate process, saving the family time, money, and significant administrative headaches.
Think of it this way: the witnesses make the will valid. The notary makes the will easier to prove.
Who Should—and Should Not—Act as a Notary
The notary’s role, while procedural, demands impartiality. A notary public has a fiduciary duty to be a disinterested party to the transaction. This is why a person who is a beneficiary in the will should never, under any circumstances, notarize the self-proving affidavit.
Doing so creates a clear conflict of interest and invites a will contest from disgruntled relatives. They could argue that the beneficiary-notary had a financial incentive to influence the testator or to overlook procedural errors during the signing. Even if the claim is baseless, it can mire an estate in costly and painful litigation for years.
At our firm, the attorneys and paralegals are commissioned notaries public. When we supervise a will execution, we serve as the witnesses and the notary. This creates a controlled environment where we can ensure every statutory requirement is met, the self-proving affidavit is properly executed, and the entire process is unimpeachable. Stewardship.
A will is the cornerstone of a family’s generational plan. Relying on a bank teller or a local notary who doesn’t understand the specific formalities of a will execution is a risk not worth taking. The document is simply too important.
If you have an existing will that was not prepared or executed under the supervision of an estate planning attorney, it may not be as secure as you think. We can conduct a formal review of your will and its execution to identify any potential vulnerabilities before they become a problem for your family.
