No, a last will and testament does not need to be notarized to be legally valid in almost every state. What the law actually requires is your signature and the signatures of at least two witnesses who watched you sign. Notarization comes in through an optional attachment called a self-proving affidavit, and while skipping it doesn’t invalidate anything, adding it is one of the cheapest ways to save your family time and money in probate.
What the Law Actually Requires
The formalities are simpler than most people expect. You (the testator) sign the will in the physical presence of at least two witnesses. Those witnesses then sign the will themselves, confirming they saw you sign, that you told them the document was your will, and that you appeared to be of sound mind and acting freely. That’s the core of it. No lawyer needs to draft it. No notary stamp is required on the will itself.
Who serves as a witness matters. Each should be a legal adult and a “disinterested party,” meaning someone who does not stand to inherit under the will. If a beneficiary signs as a witness, most states apply a purging statute: the will stays valid, but the gift to that witness gets reduced or wiped out entirely. The document survives; the person who witnessed it may lose their inheritance. It’s one of the most common and avoidable mistakes in DIY estate planning.
One narrow exception exists. A single state treats notarization as a formal requirement for its standard will type, requiring both a notary and two witnesses present together at signing. If you live there, an estate attorney can walk you through it. Everywhere else, witnesses alone do the job.
Why a Self-Proving Affidavit Is Worth Adding
After you die, your will goes through probate, the court process that confirms the document is legitimate and authorizes distribution of your assets. Without a self-proving affidavit, the probate court has to track down your original witnesses so they can testify that the signing was real and proper. Years may have passed. Witnesses move, become incapacitated, or die. Locating them costs time and money. If they can’t be found at all, the court has to rely on other evidence to validate the will, which drags out the whole process.
A self-proving affidavit heads that off. It’s a separate sworn statement, attached to the will, in which you and your witnesses confirm under oath before a notary public that all the legal formalities were followed. Once the court sees that notarized affidavit, it can accept the will as properly executed without calling anyone to testify. The practical effect is a faster, cheaper probate.
How to Get One Signed
The smartest approach is to sign the affidavit at the same time you sign the will, while everyone is already in the room. You can add one later, but that means reassembling the same witnesses, which gets harder as time passes.
The process:
- Prepare the affidavit form. It includes your declaration that this is your will and you signed it voluntarily, plus each witness’s declaration that they watched you sign and that you appeared to be of sound mind. Most states provide specific statutory language.
- Appear before a notary. You and both witnesses must be physically present with the notary at the same time. The notary verifies everyone’s identity, typically through a government-issued ID.
- Sign under oath. The notary administers an oath, everyone signs, and the notary signs and affixes an official seal.
The cost is minimal. Many banks, shipping stores, and public libraries offer notary services for a small fee, sometimes free for account holders. One step, potentially hundreds or thousands of dollars saved in probate costs later.
Can You Notarize Remotely?
A growing number of states now permit remote online notarization, where you appear before the notary by video call rather than in person. Whether that option extends to self-proving affidavits for wills depends on your state’s specific rules. Some states explicitly allow it, and their statutory affidavit forms include checkboxes for “physical presence” versus “online notarization.” Others restrict remote notarization to certain document types or impose additional requirements for estate planning documents. If an in-person visit is difficult, check whether your state accepts remote notarization for wills before relying on it.
When the Rules Are Different: Holographic and Electronic Wills
Handwritten (Holographic) Wills
Roughly half the states recognize a handwritten will, known as a holographic will, as valid even without witness signatures. The theory is that your handwriting itself serves as proof of authenticity. No notarization is required either.
The rules vary. Some states require the entire document to be in your handwriting. Others require only that the “material portions,” meaning the key provisions about who gets what, are handwritten. A few states impose additional conditions, like requiring the will to be found among your important papers after death.
Holographic wills are significantly easier to challenge in court than formally witnessed ones. Disputes often involve handwriting experts, and questions about competence or pressure are harder to resolve without witnesses who can speak to the signing. Estate planners treat holographic wills as a last resort. If you have time to handwrite a will, you have time to get two witnesses in the room.
Electronic Wills
At least 15 states now accept electronic wills, which are created, signed, and stored digitally. This is a recent shift. Federal law and the older Uniform Electronic Transactions Act both carved out explicit exceptions for wills, so electronic signatures historically did not count for estate planning documents. The Uniform Electronic Wills Act was drafted to close that gap, allowing electronic execution while still requiring that the signature be witnessed or notarized contemporaneously.1Uniform Law Commission. Current Acts – E
States that have adopted electronic will laws don’t all follow the same model. Requirements around witness presence, the type of electronic signature accepted, and whether remote witnessing is allowed differ. If you’re considering an electronic will, verify your state’s specific rules. An electronic will executed in a state that recognizes them may face complications if you later move to a state that doesn’t.
Where You Keep the Original Matters
A properly witnessed and notarized will does no good if nobody can find it. If the original cannot be located after your death, most courts apply a rebuttable presumption that you destroyed it on purpose, meaning the court will assume you revoked it unless someone produces strong evidence to the contrary. A photocopy alone often isn’t enough. The result is that your estate gets distributed under state intestacy law as if you never had a will at all.
Common storage options include a fireproof safe at home, a safe deposit box at a bank, or filing the original with your local probate court. Many courts accept wills for safekeeping during your lifetime for a small fee, issuing a receipt and storing the document in a secure vault. The will remains yours to withdraw, amend, or replace at any time. Whichever method you choose, tell your executor where the original is and make sure they can access it when the time comes.
