The Basic Rule for Will Witnesses
Witnessing a will is straightforward in most cases. Arizona law says any person who is generally competent to be a witness may act as a witness to a will. There is no minimum age specified in the statute, no requirement that the witness be an Arizona resident, and no prohibition on friends or neighbors serving in this role.
A person who is generally competent to be a witness may act as a witness to a will.
A.R.S. § 14-2505(A)The standard is simple: if a person could testify in court, they can witness a will. This keeps the process accessible while still ensuring the people signing have the capacity to understand what they are observing.
When a Witness Cannot Be a Beneficiary
For wills executed on or after October 1, 2019, Arizona added a critical safeguard. A person who is named as a beneficiary in the will, or who is related by blood, marriage, or adoption to a beneficiary, may not serve as a witness. The one exception: if the will is made self-proving under A.R.S. 14-2504 or 14-2519, this restriction does not apply.
Unless the will is made self-proved as prescribed in section 14-2504 or 14-2519, a person may not act as a witness to a will if that person is a devisee under that will or is related by blood, marriage or adoption to a devisee under that will.
A.R.S. § 14-2505(B)This matters because having an interested witness can invite challenges. If someone who inherits under the will also signed as a witness, it raises questions about whether the testator was acting freely. Making the will self-proving through a notarized affidavit eliminates this concern and streamlines probate admission.
For this section, "devisee" includes not just a person named directly in the will, but also a beneficiary of a trust that receives assets under the will. That broader definition closes a potential gap.
