No. A California will cannot be notarized instead of witnessed. California Probate Code section 6110 requires a typed or printed will to be signed by two witnesses, and notarization does nothing to replace that requirement. A will that carries only a notary’s seal, with no witnesses, is not a valid formal will in California.1California Legislative Information. California Code Probate 6110 – Execution of Wills
Why a Notary Can’t Stand In for Witnesses
Witnesses and notaries do different legal jobs. A notary verifies identity and administers oaths. Witnesses confirm something a notary isn’t asked to confirm: that the person signing appeared to be acting voluntarily and seemed mentally competent to make a will. Identity verification tells a probate court who signed; it doesn’t tell the court whether the signer understood what they were doing or was free from pressure.
Many states let a will become “self-proving” through a notarized affidavit, which lets the will be admitted to probate without witness testimony. California is not one of those states. There is no self-proving affidavit procedure under California probate law, so a notary stamp carries no special weight on a will. California courts validate wills through the subscribing witnesses — their sworn statements or, if needed, their testimony.
Having the signing notarized on top of the two witness signatures is harmless and some attorneys suggest it as a belt-and-suspenders measure to help pin down the date and the identities of everyone present. It is never a substitute for the witnesses themselves.
What the Witness Rule Actually Requires
Two witnesses must be present at the same time. Each must watch you either sign the will or acknowledge a signature already on it. Each then signs the will understanding that the document is your will.1California Legislative Information. California Code Probate 6110 – Execution of Wills
Any person generally competent to be a witness qualifies. The statute sets no specific age, but the witness should be a competent adult. A notary can serve as one of the two witnesses, acting in that moment as a private individual signing in the witness capacity rather than performing a notarial act.2California Legislative Information. California Code Probate 6112
One trap worth flagging: avoid using a beneficiary as a witness. The will doesn’t automatically fail, but if there aren’t two other disinterested witnesses, the law presumes the witness-beneficiary obtained their gift through fraud or undue influence. If they can’t rebut that presumption, they take the smaller of what the will gives them or what they would have inherited with no will at all — often nothing, if they’re not a close relative.2California Legislative Information.

The One Will That Needs Neither Witnesses nor a Notary
California recognizes handwritten wills, called holographic wills, which require no witnesses and no notarization. A holographic will is valid if the signature and the material provisions — essentially, who gets what — are in your own handwriting. The whole document doesn’t have to be handwritten; language showing testamentary intent can appear on a printed form, but the dispositive terms and the signature must be in your hand.3California Legislative Information. California Code PROB 6111 – Holographic Will
Holographic wills come with their own problems. Without witnesses, someone familiar with your handwriting usually has to verify authenticity during probate. Disputes over handwriting, unclear language, or missing dates can delay probate or sink the will. An undated holographic will can be thrown out entirely if it conflicts with another will and no one can tell which came first. Notarizing a holographic will doesn’t fix any of this, because it isn’t what the statute asks for.3California Legislative Information. California Code PROB 6111 – Holographic Will
If You Only Notarized Your Will
If a will was signed before a notary without the required two witnesses, it is defective as a formal will. There is one backstop. Under California’s harmless error rule, the probate court can still treat a defective will as valid if the person offering it proves by clear and convincing evidence that the deceased intended the document to be their will when they signed it.1California Legislative Information.

Clear and convincing evidence is a high bar, well above the standard that governs most civil disputes. Courts look at what the person said to others about the will, what other steps they took that suggest they believed the document was binding, and whether any fraud is in the picture. This is a safety net for families to argue in court, not a planning tool. Relying on it means expensive litigation with no guarantee of success.
If the will is ultimately rejected, the estate passes under California’s intestate succession rules as though no will existed. That formula ignores your actual wishes. Unmarried partners, stepchildren, close friends, and charities receive nothing under intestate succession no matter how close they were to you. The real cost of a notarized-but-unwitnessed will isn’t a technicality — it’s the complete loss of your choices about your own estate.
If you have a will sitting in a drawer that was notarized but not witnessed, the fix is simple: sign a new one, in front of two competent, disinterested adult witnesses who are present together, following the section 6110 formalities. Add the notary too if you like. Just don’t let the notary stand alone.
