How to Make a Valid Will in Arizona

Arizona in depth

Arizona is flexible in ways that surprise people: it fully recognizes handwritten wills, it never requires a notary to make a will valid, and its Uniform Probate Code framework is meant to admit wills, not defeat them. But it is unforgiving where it counts. Arizona has no harmless-error rule — no judge can rescue a will that missed the signing formalities unless it happens to qualify as a handwritten will — and because Arizona is a community-property state, what you can actually leave a spouse is not what most people assume.

The statute facts above give you the rules. This section covers where Arizona wills actually go wrong, an interested-witness rule that is stricter than the standard Uniform Probate Code, and the protections built into Arizona law that you cannot draft around.

Five ways an Arizona will gets thrown out

Most Arizona wills that fail, fail on how they were signed — not on what they say. And unlike a growing number of states, Arizona gives you no general second chance to fix a botched signing. These are the recurring ones.

1. 1

   Notarizing the will instead of getting two witnesses

   A typed Arizona will must be signed by at least two witnesses, each of whom signed within a reasonable time after witnessing you sign the will or acknowledge your signature (A.R.S. § 14-2502). Notarization is not required and is not a substitute — a carefully notarized will signed by fewer than two qualifying witnesses is simply not executed. And because Arizona has no harmless-error rule, there is no courtroom rescue for it unless the will happens to be entirely in your own handwriting. Get the two witnesses; the notary is optional.

2. 2

   Using an interested witness on a will you didn't self-prove

   This is an Arizona-specific trap that is stricter than the standard Uniform Probate Code. Arizona does not purge or void a gift to a witness — but for a will executed on or after October 1, 2019 that is NOT self-proved, an interested person (a devisee, or someone related to a devisee by blood, marriage, or adoption) may not act as a witness, and using one can invalidate the attestation (A.R.S. § 14-2505). A self-proved will (§ 14-2504) is exempt. The clean fix works both ways: use disinterested witnesses, and self-prove the will to neutralize the rule entirely.

3. 3

   A "holographic" will that is typed or filled in on a form

   Arizona recognizes handwritten wills with no witnesses at all — but only if the signature and the material provisions are in your own handwriting (A.R.S. § 14-2503). People buy a printed will form, fill in the blanks, and sign it without witnesses. Because the material provisions are not in your hand and there are no two witnesses, it is neither a valid holographic will nor a valid attested one.

4. 4

   Assuming a spoken wish or deathbed statement counts

   Arizona does not recognize nuncupative (oral) wills at all. Title 14 authorizes only paper wills, handwritten (holographic) wills, and — since 2019 — electronic wills. A spoken instruction to family, however clear and however many people heard it, has no effect as a will in Arizona. Put it in writing and sign it in front of two witnesses.

5. 5

   Signing electronically without meeting the e-will rules

   Arizona does recognize electronic wills (A.R.S. § 14-2518, since 2019), but they have their own strict requirements — an electronic record readable as text, and two witnesses who are physically or electronically present (any electronically-present witness must be physically located in the United States). A self-proved electronic will further requires a notary and a qualified custodian (§ 14-2519). A casual e-signed PDF or a will "witnessed" over an ordinary video call does not meet these rules. If in doubt, sign a paper original in wet ink with two witnesses physically present.

Arizona protects a spouse through community property, not an elective share

Arizona is a community-property state, and this changes the whole picture. Property a married couple acquires during the marriage is generally community property, and one-half of it already belongs to the surviving spouse by operation of law — the decedent cannot devise that half away. Your will controls your one-half of the community property plus your own separate property; it does not reach your spouse's half.

This is why Arizona has no New York-style elective or forced share: there is no statute letting a spouse "claim one-third against the will," because the spouse is already protected by owning half of the marital estate. There is no elective-share provision anywhere in Title 14. If your plan depends on how community versus separate property is divided, sort that out while drafting — the court applies the community-property math regardless of what the will says.

The spouse or child you forgot, and the ex-spouse you didn't remove

Marriage, a new child, and divorce can all rewrite an Arizona will by operation of law. If you marry after signing your will and never update it, the new spouse is an "omitted spouse" and can claim the share they would have received had you died without a will — unless the will was made in contemplation of the marriage, or you provided for the spouse outside the will, or the omission was intentional (A.R.S. § 14-2301). A child born or adopted after the will who is left unprovided for takes an intestate share on the same logic, unless the omission was intentional (§ 14-2302).

Divorce cuts the other way. A final divorce or annulment automatically revokes every gift and every fiduciary appointment in favor of your former spouse, and it severs the right of survivorship in property the two of you held as joint tenants (§ 14-2804) — the ex is written out by operation of law. None of this is a substitute for redrafting: the safe move is to revisit the will after any marriage, divorce, or new child.

Handwritten wills are valid — but the whole plan has to be in your hand

An Arizona holographic will needs no witnesses and no notary. What it needs is that your signature and all of the material provisions — who gets what — are in your own handwriting (A.R.S. § 14-2503). Pre-printed matter can appear on the page, but the dispositive terms cannot be typed or filled into a form. This is the one route that can save a will that failed the ordinary two-witness formalities.

It is a genuine emergency option, not a preference. A handwritten will is far easier to attack than a witnessed, self-proved typed will, and because Arizona has no harmless-error safety valve, the holographic form is the only fallback when a signing goes wrong. Arizona will also let extrinsic evidence show that you intended a document to be your will (§ 14-2502(B)), but that is about proving intent — it is not a power to forgive missing signatures.

Arizona has no harmless-error rescue

A number of states let a judge admit a will that was signed incorrectly if the person offering it proves by clear and convincing evidence that you intended it to be your will. Arizona does not. There is no dispensing-power provision in Title 14, so a will that fails the § 14-2502 formalities has exactly one lifeline: qualifying as a handwritten (holographic) will under § 14-2503. If it is typed and under-witnessed, and not entirely in your hand, no clear-and-convincing showing will save it.

This is exactly why the two-witness rule and the interested-witness trap carry so much weight in Arizona. A missing witness or a disqualified interested witness on a non-self-proved will cannot be argued away after death. Execute cleanly in front of two disinterested witnesses, and — for probate ease and to neutralize the interested-witness rule — add the self-proving affidavit before a notary the same day.

The self-proving affidavit, small estates, and where an Arizona will is proved

Arizona does not require notarization for a will to be valid, but it offers a self-proving affidavit that does real work here. You and both witnesses swear before a notary — either at the same time the will is signed or added later — that the will was properly executed (A.R.S. § 14-2504). A self-proved will can be admitted without tracking your witnesses down to testify, and — uniquely in Arizona — it also exempts the will from the interested-witness disqualification (§ 14-2505). A signature on the self-proving affidavit even counts as a signature on the will itself if one is needed to prove execution.

Arizona probates wills in the Superior Court, in the county where you were domiciled at death (§ 14-3201). Many estates skip formal probate entirely: as of HB2116, effective September 26, 2025, an heir can collect personal property by affidavit when the net estate's personal property is $200,000 or less (usable 30 days after death), and can transfer real property by affidavit when the real property is worth $300,000 or less net of liens (usable 6 months after death) (§ 14-3971) — both limits raised sharply from the old $75,000 and $100,000 figures. And Arizona imposes no state estate tax and no inheritance tax, so what passes under the will is not reduced by a state death tax.

Who Can Make a Will in Arizona?

You must be at least 18 years old to make a will in Arizona. The testator must be eighteen years of age or older and of sound mind (ARS § 14-2501). The statute states in full: 'A person who is eighteen years of age or older and who is of sound mind may make a will.'

Signing Requirements

Must be in writing. Can be typed, printed, or handwritten. Electronic wills are also permitted under ARS 14-2518. If you are physically unable to sign, Another person may sign in the testator's name in the testator's conscious presence and by the testator's direction.

Witness Requirements in Arizona

Arizona requires 2 witnesses. Must be generally competent to be a witness (ARS 14-2505(A)). No minimum age is stated in the witness statute; the 18-year-old and sound-mind requirements in ARS 14-2501 apply to the testator, not witnesses. For wills executed on or after October 1, 2019, interested witnesses (devisees or persons related by blood, marriage, or adoption to a devisee) are disqualified unless the will is self-proved under ARS 14-2504 or 14-2519 (ARS 14-2505(B)). Each witness must sign within a reasonable time after witnessing either the signing of the will or the testator's acknowledgment of that signature or acknowledgment of the will (ARS 14-2502(A)(3)).

Interested witnesses: For wills executed on or after October 1, 2019, interested witnesses are DISQUALIFIED: a person may not act as a witness if that person is a devisee under the will or is related by blood, marriage, or adoption to a devisee, unless the will is made self-proved as prescribed in ARS 14-2504 or 14-2519. The pre-2019 rule permitting interested witnesses was repealed by HB2054 (54th Legislature, 1st Regular Session, Chapter 46, effective October 1, 2019)

Notarization in Arizona

Notarization is not required for a will to be valid in Arizona. Not required for validity. Required for self-proving affidavit

Self-Proving Affidavit

Arizona allows a self-proving affidavit, which simplifies probate by eliminating the need for witnesses to testify in court. The testator and witnesses must sign an affidavit before an officer authorized to administer oaths under the laws of the state in which execution occurs, evidenced by the officer's certificate under official seal. A will may be made self-proved simultaneously with execution (ARS 14-2504(A)) or at any time after execution (ARS 14-2504(B)). A signature affixed to the self-proving affidavit attached to the will is considered a signature affixed to the will if necessary to prove due execution (ARS 14-2504(C)). The statute does not limit the qualifying officer to a notary public.

Handwritten (Holographic) Wills

Arizona does recognize holographic wills. Valid whether or not witnessed if the signature and the material provisions are in the testator's handwriting (ARS 14-2503). Testamentary intent can be established by extrinsic evidence, including, for holographic wills, portions of the document that are not in the testator's handwriting (ARS 14-2502)

Electronic Wills

Arizona recognizes electronic wills. Arizona recognizes electronic wills under ARS 14-2518. Requirements (ARS 14-2518(A)): (1) created and maintained in an electronic record readable as text at time of signing; (2) electronic signature of testator, or of another individual in the testator's conscious presence and by the testator's direction; (3) electronic signatures of at least two witnesses, each of whom was physically present or electronically present with the testator when the testator signed or acknowledged the will, and who electronically signed within a reasonable time after witnessing — if a witness was electronically present, they must have been physically located within the United States at the time of serving as a witness (ARS 14-2518(A)(3)(c)); (4) must state the date the testator and each witness electronically signed; (5) must contain a copy of a government-issued identification card of the testator that was current at the time of execution. NOTE: a qualified custodian is required only for a self-proved electronic will under ARS 14-2519 (not a requirement for basic electronic will validity under ARS 14-2518). ARS 14-2520 governs custodian eligibility: custodian may not be related to the testator by blood, marriage, or adoption, and may not be a devisee under the will or related by blood, marriage, or adoption to a devisee.

How to Revoke a Will in Arizona

In Arizona, a will can be revoked by:

• •Executing a subsequent will that revokes the previous will or part expressly or by inconsistency
• •Performing a revocatory act on the will if the testator performs the act with this intent — 'revocatory act on the will' includes burning, tearing, canceling, obliterating, rendering unreadable or destroying the will or any part of it
• •Another person may perform the revocatory act in the testator's conscious presence and by the testator's direction

ARS 14-2507. 'Rendering unreadable' is an expressly enumerated revocatory act. ARS 14-2507 (subsections A–D only) contains no language addressing electronic will revocation; the words 'electronic will', 'electronic record', and 'deleting' do not appear in this section. [Note: HB2471 (53rd Leg. 2nd Reg.), which would have added 'electronic will' throughout 14-2507 including an A.3 subsection covering deletion/obliteration of electronic wills, was vetoed by the Governor on April 20, 2018. HB2656 (Chapter 328), the bill that actually became law effective 2019, amended 14-2507 without adding any electronic will language.]

Special Provisions in Arizona

Arizona is a community property state. Surviving spouse is entitled to their half of community property. Separate property may be disposed of freely by will. Arizona has no elective share statute because community property protections serve that function
