How to Write a Will in Arizona (2026 Guide)

This is general legal information for Arizona, not legal advice. Will laws change, and specific situations can have exceptions. For any complex case, consult a licensed attorney in Arizona.

Why Having a Will Matters

A will is the simplest, clearest way to say what happens to your property, your minor children, and your affairs after you die. Without one, you die "intestate" and Arizona’s default inheritance rules (called intestate succession) take over. Those rules are rigid and generic — they do not know your relationships, your intentions, or the people you care about most. They follow a fixed formula.

The cost of skipping a will is not hypothetical. It plays out the same way in Arizona as everywhere else: unmarried partners locked out, stepchildren with nothing, pets in shelters, court-appointed administrators, family disputes over items and money, and a probate process that is slower, messier, and more expensive than it needed to be. Whatever you own — even if you think it’s "not much" — someone will have to deal with it after you’re gone. A will decides whether that someone is you or a judge.

A simple Arizona will takes about ten minutes to draft using a free tool and costs nothing. You can start drafting yours now. The rest of this guide walks you through what makes a will legally valid in Arizona and how to avoid the technical mistakes that most commonly cause wills to be thrown out.

Arizona Will Requirements at a Glance

• Minimum age: 18 years old
• Written form: Must be in writing. Can be typed, printed, or handwritten. Electronic wills are also permitted under ARS 14-2518
• Witnesses required: 2
• Notarization: Not required for a standard signed will
• Self-proving affidavit: Yes — recommended, it speeds up probate later
• Holographic (handwritten) wills: Yes
• Electronic wills: Yes

Testamentary Capacity

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.'

Signature Requirements in Arizona

You must personally sign the will. Arizona does allow proxy signing in specific cases: 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))

Presence rules: 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)

The safest approach in every state, including Arizona, is to use witnesses who are adults, not beneficiaries under the will, and not the person you’ve named as executor. This avoids any question about whether a witness’s inheritance could be "purged" for being an interested party.

Notarization and Self-Proving Affidavits

Arizona does not require a will to be notarized to be valid. A signed and witnessed will is enough. Not required for validity. Required for self-proving affidavit

Arizona does allow a self-proving affidavit, which is a short notarized document attached to the will where you and your witnesses swear under oath that everything was signed properly. It is optional, but it is strongly recommended — a self-proving affidavit means the probate court can admit the will without having to contact your witnesses later. 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.

Holographic, Electronic, and Oral Wills in Arizona

Holographic (handwritten) wills: Recognized in Arizona. 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: Recognized in Arizona under specific conditions. 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.

Nuncupative (oral) wills: Not recognized in Arizona.

How to Revoke or Update a Arizona Will

If you already have a will and want to change it, Arizona recognizes these revocation methods: 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.]

The cleanest approach is to draft a new will that starts with the sentence "I revoke all previous wills and codicils," then sign it with the proper witnesses. Destroy old copies when you do. Small updates can technically be done by codicil (a formal amendment), but a fresh will is usually easier to read and harder to contest.

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

Step-by-Step: Writing a Valid Arizona Will

1. Take inventory. Bank accounts, vehicles, property, valuables, digital assets, pets.
2. Decide who gets what. Be specific for items that matter (names, addresses, account identifiers). Use a residuary clause ("everything else goes to...") to catch anything you forget.
3. Name an executor. The person who handles your estate. Pick someone trustworthy, organized, and likely to outlive you. Name a backup too.
4. Name a guardian for minor children if you have kids under 18. This is the single most important reason for a will if you’re a parent.
5. Draft the document. Our free drafting tool generates a Arizona-specific will in about 10 minutes, with all the correct clauses in the correct order.
6. Print the will. Don’t rely on a digital copy for signing.
7. Sign in front of 2 adult witnesses who are not named as beneficiaries. You all need to be in the same room at the same time. You sign first, they sign while watching.
8. Sign the self-proving affidavit in front of a notary. This is optional but speeds up probate later.
9. Store it somewhere findable. A fireproof home safe is the standard choice. Tell your executor where it is.
10. Review every few years and after major life events (marriage, divorce, new child, moving out of Arizona, major asset changes).

Common Arizona Will Mistakes to Avoid

• Wrong number of witnesses. Arizona requires 2. More is fine; fewer invalidates the will.
• Using a beneficiary as a witness. Can cause the beneficiary’s share to be "purged" (forfeited).
• Not signing in the witnesses’ presence. The signing has to happen as a ceremony, with everyone in the same room.
• Forgetting a residuary clause. Without it, anything you didn’t specifically mention falls into intestate succession.
• Storing the will where nobody can find it. An unfindable will is the same as no will.
• Not updating after major life events. An ex-spouse named in an old will can still inherit in some situations.
