Yes, a notary can notarize a will in every U.S. state, but in most states that notarization alone will not make the will legally valid. Witnesses are what a will needs to be enforceable. The real reason to bring in a notary is to attach a self-proving affidavit, which spares your family from having to track down those witnesses years later during probate.
What a Notary Actually Does When Signing a Will
Notarization and legal validity are two different things, and mixing them up is the most common mistake people make with wills. A notary verifies the signer’s identity, confirms the signer appears to be acting voluntarily, and applies a stamp. That stamp does not turn a document into a valid will. If the will fails to meet your state’s execution requirements, the notary’s seal will not save it in probate court.
What the notary does add is an independent verification layer. The stamp and the journal entry create a contemporaneous record that you appeared in person, presented valid identification, and signed willingly. If someone later claims the signature was forged or that you were pressured, that record becomes useful evidence. The bigger practical payoff, though, comes through the self-proving affidavit.
Before any of that matters, the will has to meet baseline execution rules: a written document, your signature, at least two disinterested witnesses who watched you sign, sound mind, and legal age (generally 18). Witnesses must be “disinterested,” meaning they do not inherit under the will. In some states a beneficiary who serves as witness can forfeit their inheritance or trigger a challenge.1Legal Information Institute. Self-Proving Will
Why Estate Attorneys Recommend Notarizing a Will
The reason to involve a notary is the self-proving affidavit. This is a sworn statement, signed by you and your witnesses in front of a notary, declaring that you were of sound mind, acting voluntarily, and that the witnesses observed your signature. The notary stamps it and it gets attached to the will.
Without a self-proving affidavit, probate courts typically require your witnesses to appear and confirm the will is legitimate. If years have passed, witnesses may have moved, become ill, or died. Tracking them down is expensive and slow, and if the court can’t locate them, your family may face a contested probate. A self-proving affidavit eliminates that problem: the notarized affidavit is treated as sufficient proof that the will was properly executed, so no one has to testify.1Legal Information Institute. Self-Proving Will
The format is standardized in states following the Uniform Probate Code. You sign a sworn statement confirming voluntary signing and mental capacity. Each witness signs a sworn statement confirming they observed the signing and believed you were competent and free from undue pressure. The notary administers the oath and completes the notarial certificate.
Self-proving affidavits are recognized in nearly every state. A small number of jurisdictions, including Ohio and the District of Columbia, do not allow them.1Legal Information Institute. Self-Proving Will If you live in one of those places, choose younger, reliable witnesses who are likely to be available when the will is admitted to probate.
States Where Notarization Can Replace Witnesses
In most states, witnessing and notarization serve different purposes and you need both. A few states break that pattern. Colorado and North Dakota allow a testator to have a will notarized instead of witnessed, treating the notary’s acknowledgment as legally equivalent to witness signatures. Louisiana is the only state that actually requires a notary for will execution, and it still requires two witnesses on top of that.
States that have adopted the revised version of UPC Section 2-502 give testators the option to acknowledge the will before a notary instead of having two witnesses sign.2Legal Information Institute. Uniform Probate Code The important word is “option.” You still have to complete one path or the other properly; a will with neither witnesses nor notarization won’t hold up.
If you are unsure whether your state accepts notarization as a substitute for witnesses, the safest approach is to do both. Have two disinterested witnesses sign, then have you, the witnesses, and the notary complete a self-proving affidavit. This adds almost nothing to the cost and protects the will regardless of how your state’s rules are interpreted.
What Happens if a Will Is Notarized but Not Witnessed
This is the scenario that catches people off guard. Someone visits a notary, signs the will with the notary’s stamp, and assumes the job is done. Later the family discovers the will has no witness signatures.
In most states, that will fails. Notarization does not cure the absence of witnesses. The court may refuse to admit the document to probate, and the estate gets distributed under the state’s default inheritance laws as if there were no will at all. If your wishes differ from the statutory default, the result can be devastating.
A few courts have treated the notary as the equivalent of a witness, sometimes rescuing a will that had only one witness instead of the required two. This is applied inconsistently and is not something to plan around. States following the revised UPC handle these situations better because notarization is an explicit alternative there. Everywhere else, a notarized but unwitnessed will is a gamble your family shouldn’t be forced to take.
Can a Notary Also Serve as a Witness
The answer depends on your state. The general rule is that one person can serve as either the notary or a witness on the same document, but not both. A witness attests to the testator’s mental state and voluntary intent. A notary verifies identity and administers oaths. Combining the two roles can undermine the independence each one is supposed to provide.
Some states, particularly those following the UPC model, explicitly allow the notary to double as a witness. The self-proving affidavit form in UPC Section 2-504 contemplates that the officer administering the oath may also be a witness to the will. Other states prohibit it. If your second witness is going to be the notary, confirm your state’s rule first. Getting this wrong can invalidate the self-proving affidavit or open the door to a challenge.
When a Notary Should Refuse, and Conflicts of Interest
Notaries have a legal obligation to refuse in certain situations, and refusals are more common with wills because testators are sometimes elderly, ill, or pressured by family. A notary should decline if:
- The signer cannot present valid government-issued identification.
- The signer appears confused, heavily medicated, or otherwise unable to understand what they are signing.
- A family member is pressuring the testator, hovering during the signing, or speaking on the testator’s behalf.
- The signer is under the legal age to make a will.
- The transaction otherwise looks fraudulent or deceptive.
If a notary declines to proceed, take it seriously. Their hesitation may be preventing a will that would fail later.
Conflicts of interest sit in the same category. A notary who stands to benefit from the will faces an obvious conflict, and in most states performing the notarization anyway makes the notarial act voidable. Notaries should not notarize any document in which they are named or from which they would receive a direct benefit. A notary who is a beneficiary, a relative of one, or a close associate of the testator should step aside. A voidable notarization can unravel the self-proving affidavit and push the will back into a contested probate, which defeats the whole reason for involving a notary.
Remote Online Notarization and Electronic Wills
Remote online notarization, where the notary and signer connect over video, is authorized in 47 states and the District of Columbia for notarial acts generally. Wills are treated separately. Some states that permit remote notarization carve out estate planning documents and require in-person execution. Before using remote notarization for a will, confirm your state allows it for that specific document type. Identity verification for remote sessions is typically stricter than in-person notarization and often requires multi-factor authentication, credential analysis, and knowledge-based questions.
Electronic wills are a related but distinct question. As of early 2026, roughly 15 states and the District of Columbia have enacted electronic wills legislation. Under the Uniform Electronic Wills Act, the testator’s electronic signature must be witnessed contemporaneously, or notarized contemporaneously in states that allow notarized wills.3Uniform Law Commission. Current Acts – E Several states, including Texas, do not recognize electronically signed wills at all, regardless of whether they are notarized remotely or in person. This area of law is changing quickly, so verify your state’s current rule before relying on either a remote notary or an electronic signature for your will.
