I’ve seen it happen more than once in Brooklyn’s Surrogate’s Court. A family comes in with what they believe is a perfectly valid will, signed by their late father a decade ago. But the court clerk asks a question that stops them cold: “Where are the witnesses who signed this?” One has since passed away, and the other moved to Florida years ago. The probate process, which should have been straightforward, just became a logistical and financial burden of tracking down a person and compelling testimony from out of state.
This exact scenario is why the role of a notary public in a will signing ceremony is so frequently misunderstood. People often believe the notary’s stamp is what makes the will “official.” It is not. But its presence—or absence—can dramatically change the experience your loved ones have after you are gone.
What Actually Makes a Will Valid in New York
A will does not need to be notarized to be legally valid in New York. The core requirements are spelled out in our Estates, Powers and Trusts Law (EPTL). Specifically, EPTL § 3-2.1 dictates that for a will to be duly executed, it must be:
- 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.
- The testator must declare to the witnesses that the document they are signing is, in fact, their will.
- The two witnesses must also sign the will, typically adding their addresses.
That’s it. If those steps are followed, the will is valid. The statute does not mention a notary public. So why do we, as a firm, insist on having a notary present at every single will signing we supervise? Because of what happens next.
The Self-Proving Affidavit: A Tool for a Smoother Probate
The notary isn’t there to validate the will itself. The notary is there to validate the witnesses’ signatures on a separate, but attached, document called a “self-proving affidavit.” This is an oath, taken by the witnesses under penalty of perjury, at the same time the will is signed.
In this affidavit, the witnesses swear to a number of critical facts before the notary:
- That they witnessed the testator sign the will.
- That the testator declared it to be their will.
- That the testator appeared to be of sound mind, memory, and understanding.
- That the testator was not under any restraint.
The notary then takes their acknowledgment, signs the affidavit, and applies their official stamp. This simple act transforms the affidavit into sworn testimony. It effectively “locks in” the witnesses’ statements at the moment of execution, creating a powerful legal presumption that the will was properly signed.
Why This Matters in Surrogate’s Court
When your executor submits your will to the Surrogate’s Court for probate, their job is to prove its validity. Without a self-proving affidavit, the court often requires the witnesses to be located. They must then sign a deposition or even appear in court to testify about the signing ceremony—just as in the opening story.
This process can be time-consuming and expensive. Witnesses move. They pass away. Sometimes, they become estranged from the family and are uncooperative. Any of these contingencies can add months or even years of delay and legal fees to the administration of an estate.
When a will is accompanied by a properly executed self-proving affidavit, however, the court can accept it at face value. Under SCPA § 1406, the affidavit provides the court with sufficient proof that the will was properly executed. The search for witnesses is avoided, and the probate process can proceed efficiently. It is a simple, prudent step that converts a future uncertainty into a present certainty.
This isn’t just about paperwork; it’s about stewardship. It’s a deliberate act of care for the family you are leaving behind, ensuring they are not burdened by procedural hurdles during a time of grief.
If you have an existing will, examine the pages that follow your signature. A self-proving affidavit is a distinct document signed by your witnesses and notarized. If you are uncertain whether this crucial step was taken, our firm can review the document to determine what your executor will face in Surrogate’s Court.
