Contested Will Cases: When Witness Testimony Is Required

Verified April 4, 2026 • 57th Legislature, 1st Regular Session

When someone formally challenges a will in Arizona, the rules for proving execution become stricter. For a will that is not self-proved, the court generally requires testimony from at least one attesting witness. A self-proved will, however, receives strong legal presumptions that reduce the burden on the proponent.

Title 14, PROBATE OF WILLS AND ADMINISTRATION

Proof Requirements in a Contested Proceeding

When a will is contested, the stakes are higher and the court demands more. If the will is not self-proved, Arizona law requires testimony from at least one of the original attesting witnesses, provided that witness is in the state, competent, and able to testify.

If evidence concerning execution of an attested will which is not self-proved is necessary in contested cases, the testimony of at least one of the attesting witnesses, if within the state, competent and able to testify, is required. Due execution of an attested or unattested will may be proved by other evidence.

A.R.S. § 14-3406(A)

If no attesting witness is available, due execution can still be proved by other evidence. This might include testimony from someone who recognized the testator's signature, expert handwriting analysis, or other documentation supporting that the will was properly signed.

The Advantage of a Self-Proving Will

A self-proving will carries significant weight in a contested proceeding. When the will includes a properly executed self-proving affidavit, the court conclusively presumes that the signature requirements were met. Other execution requirements are also presumed valid, though that presumption can be rebutted.

If the will is self-proved, compliance with signature requirements for execution is conclusively presumed and other requirements of execution are presumed subject to rebuttal without the testimony of any witness upon filing the will and the acknowledgment and affidavits annexed or attached thereto, unless there is proof of fraud or forgery affecting the acknowledgment or affidavit.

A.R.S. § 14-3406(B)

The only way to overcome these presumptions is by proving fraud or forgery in the affidavit itself. This is a high bar, which is exactly why estate planning professionals recommend making every will self-proving at the time of signing. It provides a layer of protection that matters most when it is needed most.

If evidence concerning execution of an attested will which is not self-proved is necessary in contested cases, the testimony of at least one of the attesting witnesses, if within the state, competent and able to testify, is required. Due execution of an attested or unattested will may be proved by other evidence. B.

Related Questions

What is probate, and how long does it take in Arizona?

Probate is a court-supervised process that validates a will, pays debts, and distributes assets. In Arizona, it typically takes 8 to 12 months and costs $10,000 to $15,000 in fees.

Is there a deadline to file probate in Arizona?

Yes. A.R.S. 14-3108 sets a two-year deadline. Filing within two years gives the personal representative full powers. After two years, they can only confirm title to heirs and cannot possess assets or handle creditor claims.

Can someone contest my will or trust in Arizona?

Both wills and trusts can be contested in Arizona, but trusts are much harder to challenge because they do not go through probate. A challenger must file a new lawsuit and prove compelling grounds, and no-contest clauses can discourage frivolous challenges.
