The short answer
No — a will does not have to be notarized in Arizona to be valid. Arizona actually recognizes two kinds of valid wills, and neither one requires a notary.
1. An attested (typed) will — A.R.S. §14-2502
- In writing
- Signed by you (the testator), or by someone at your direction in your presence
- Signed by at least two witnesses, each of whom signs within a reasonable time after witnessing you sign the will (or acknowledge your signature or the will)
Notarization is not required. A typed will signed by you and two witnesses is valid in Arizona.
2. A holographic (handwritten) will — A.R.S. §14-2503
Arizona honors a handwritten will. It’s valid — with no witnesses and no notary — if:
- The signature and the material provisions (who gets what) are in your own handwriting.
The rest of the document can be typed, as long as the key provisions and signature are handwritten. Holographic wills are legal in Arizona, but they’re more often contested and easy to get wrong, so they’re a reasonable emergency backup rather than the ideal plan.
The Arizona twist: the self-proving affidavit (this one is notarized)
Here’s where a notary actually helps. Arizona uses a self-proving affidavit (A.R.S. §14-2504), and that document is notarized.
A self-proving affidavit is a short sworn statement, signed by you and your two witnesses in front of a notary, confirming the will was properly executed. The benefit:
- When your will goes to probate, the court can admit it without contacting your witnesses — no tracking people down years later.
- It makes Arizona probate smoother and reduces the risk of delay.
Arizona is efficient about this: you can make the will self-proved at the same time you sign it, combining your signature, the witnesses’ signatures, and the notarization into one step. Most attorney-drafted Arizona wills are self-proved this way.
So the accurate way to say it: the will itself doesn’t need notarization, but the optional self-proving affidavit does — and for a typed will, it’s well worth doing.
So do you need a notary or not?
- For validity: No notary required. Sign a typed will with two witnesses, or write one entirely in your own handwriting.
- To make probate easier: Yes — add a self-proving affidavit to a typed will, which is notarized. Optional but recommended.
A will without a self-proving affidavit is still completely valid; it just means your witnesses (for a typed will) may need to confirm it at probate. Adding the affidavit removes that hassle.
The trap: notarized but not witnessed
The most damaging mistake is the familiar one: typing up a will, signing it in front of a notary, and skipping the two witnesses, thinking the notary “makes it official.”
A typed will that’s notarized but not witnessed is not valid in Arizona — the notary doesn’t replace the two witnesses required by §14-2502. (The only no-witness option is a valid holographic will, which must have its material provisions and signature in your own handwriting — a typed document doesn’t qualify.) If you want a typed will, you need the two witnesses.
Who can witness an Arizona will?
- Witnesses must be generally competent (adults of sound mind).
- Arizona does not void a will merely because an interested person (someone who inherits) served as a witness, but using disinterested witnesses avoids any argument about influence.
- Witnesses should sign within a reasonable time after watching you sign or acknowledge the will.
Quick checklist for a valid Arizona will
- [ ] In writing (typed, or with material provisions and signature handwritten for a holographic will)
- [ ] Signed by you
- [ ] For a typed will: two competent witnesses sign (not needed for a valid holographic will)
- [ ] Witnesses are disinterested (don’t inherit) — recommended
- [ ] Self-proving affidavit signed by you + witnesses before a notary — optional but smart
What to do if your will is notarized but not witnessed
If you typed a will and signed it in front of a notary without two witnesses, treat the typed version as invalid in Arizona (unless the material provisions and signature happen to be in your own handwriting, which would make it a valid holographic will). Fix it:
- Don’t rely on it. The notary stamp won’t carry a typed will through Arizona probate.
- Re-execute it properly — print it and sign in front of two competent witnesses.
- Make it self-proved at the same signing by adding the notarized affidavit — Arizona lets you combine these steps.
- Use disinterested witnesses (people who don’t inherit) to avoid any challenge.
Redoing it costs nothing if you handle the signing yourself, and it closes a gap that could otherwise undo your wishes.
What about electronic and online wills in Arizona?
A few practical notes for 2026:
- Arizona has been ahead of most states on electronic wills — it enacted an electronic-wills statute allowing wills to be signed and witnessed electronically under specific conditions. Even so, the safest, most-tested path is still a paper will signed in wet ink with two witnesses, because e-will procedures are exacting and newer to the courts.
- Remote online notarization is available for the self-proving affidavit, but remember notarization isn’t what makes a will valid — it only matters for the affidavit, and it never substitutes for the witnesses on a typed will.
- If you use an online will service, it will still instruct you to print, sign, and witness the final document (or follow Arizona’s e-will procedure exactly). Don’t skip that step — the document isn’t valid until it’s executed correctly, however polished the website looks.
When in doubt, sign a typed will on paper with two disinterested witnesses and a notarized self-proving affidavit. It’s inexpensive, certain, and exactly what Arizona courts expect.
The honest takeaway
A will does not have to be notarized in Arizona to be valid. A typed will needs two witnesses; a handwritten will with your handwriting in the key provisions and signature needs none. The most damaging mistake is treating a notary stamp as a substitute for witnesses on a typed will, which produces an invalid will. Get the witnesses right, then add the optional notarized self-proving affidavit — Arizona lets you do it in the same signing — so the court can admit your will without delay.
Common questions
Is a will valid in Arizona without a notary?
Yes. A typed will signed before two competent witnesses is valid with no notary, and a valid holographic will needs neither witnesses nor a notary. Notarization only matters for the optional self-proving affidavit.
Are handwritten wills legal in Arizona?
Yes — Arizona recognizes holographic wills where the material provisions and signature are in your own handwriting. They’re valid but easier to challenge, so a typed, witnessed will is safer.
What is a self-proving affidavit in Arizona?
A notarized statement signed by you and your witnesses confirming the will was executed properly. It lets the court admit the will without witness testimony. Arizona lets you make the will self-proved at the same time you sign it.
Can I notarize my will instead of using witnesses?
No. For a typed will, a notary does not replace the two required witnesses. A notarized-but-unwitnessed typed will is invalid; only a valid handwritten will can skip witnesses.
