This guide covers Arizona estate planning in plain English — the exact age, witness, and notarization rules, whether a handwritten will is valid, and how to make your will self-proving. All figures are from Arizona law, verified as of June 2026.

Arizona Will Requirements at a Glance

Here are the exact rules for making a valid will in Arizona:

Minimum age to make a will 18
Witnesses required 2
Notarization required NO — notarization is not required for a will to be valid in Arizona. However, notarization is needed to make a will self-proving under ARS 14-2504, which allows the will to be admitted to probate without requiring live witness testimony.
Handwritten (holographic) will allowed YES — under ARS 14-2503, a holographic will is valid if the signature and the material provisions are in the testator’s own handwriting. No witnesses or notarization are required. Testamentary intent may be established by extrinsic evidence, including portions of the document not in the testator’s handwriting.
Self-proving affidavit available YES — under ARS 14-2504, a will may be made self-proving either at the time of execution or at any later date. The testator and at least two witnesses must sign acknowledgments or affidavits before an officer authorized to administer oaths (typically a notary public), with the officer’s certificate under official seal attached to the will. The statute includes a sample affidavit form. A self-proving will may generally be admitted to probate without requiring live witness testimony.
Statutory will form NO — Arizona does not offer an official statutory fill-in-the-blank will form. However, ARS 14-2504 does include a statutory self-proving affidavit form, and the Arizona courts Self-Service Center provides forms for probate proceedings, living wills, and powers of attorney.

What a Arizona Will Does (and Doesn’t Do)

In Arizona, a valid will may name a personal representative (executor) to administer the estate, name a guardian for minor children, distribute the testator’s separate property and the testator’s half of community property, create testamentary trusts, make conditional bequests, and explicitly disinherit adult children. Arizona is a community property state (ARS 25-211), so each spouse owns half of community property — a will can dispose of only the testator’s half.

What a Arizona will does NOT control: A will does not control assets that pass outside probate, including life insurance proceeds with a named beneficiary, retirement accounts (401k, IRA) with a named beneficiary, payable-on-death (POD) or transfer-on-death (TOD) accounts, property held in joint tenancy with right of survivorship, and assets held in a living trust. A will also cannot dispose of the surviving spouse’s half of community property.

A will does not avoid probate — it must go through the probate process.

Oral wills in Arizona: NO — Arizona does not recognize oral (nuncupative) wills for civilians. A narrow exception may apply to members of the armed forces on active duty who declare an oral will before two witnesses, but this is not available to the general public.

How to Update or Revoke a Arizona Will

Under ARS 14-2507, a will may be revoked in whole or in part by executing a subsequent will that expressly revokes the prior will or is inconsistent with it, or by a revocatory act such as burning, tearing, canceling, obliterating, rendering unreadable, or destroying the will (performed by the testator or by another person in the testator’s conscious presence and at the testator’s direction).

Minor changes may be made by executing a codicil, which must be signed and witnessed with the same formalities as the original will. If a subsequent will makes a complete disposition of the estate without expressly revoking a prior will, there is a rebuttable presumption that the testator intended the new will to replace the old one entirely.

Other Arizona will-making rules: Arizona is one of 9 community property states — each spouse owns 50 percent of community property, and a will can only dispose of the testator’s half (ARS 25-211). Arizona does not have an elective share statute; the surviving spouse’s protection comes from community property ownership rights.

Arizona explicitly authorizes electronic wills under ARS 14-2518, which require the testator’s electronic signature, electronic signatures of at least two witnesses (who may be physically or electronically present), and a copy of the testator’s government-issued ID current at the time of execution. Witnesses who are electronically present must be physically located within the United States. ARS 14-2502 also permits witnessing of paper wills via two-way audio and video conference.

Under ARS 14-2302, a child born or adopted after the will was executed who is not mentioned in the will may be entitled to an intestate share unless the omission was intentional. An interested witness (such as a beneficiary) does not invalidate the will.

Understanding Arizona Estate Planning

Getting started with Arizona estate planning is the single best gift you can give your family. A valid Arizona will lets you decide who inherits, name an executor, and name a guardian for your children — instead of leaving it to a default state formula.

When people look into Arizona estate planning, the real answer comes down to the state’s execution rules: your age, the number of witnesses, and whether you make it self-proving. If any part of Arizona estate planning is unclear, your state court’s self-help center can point you to the official forms and resources.
