Disputes over a loved one’s estate can be some of the most emotionally charged conflicts a family ever faces. In Arizona, questions about whether a will existed, whether it was valid, or who was supposed to inherit what often lead to probate litigation. At Fortify Legal Services, we help Mesa‑area families navigate these difficult situations with clarity, strategy, and a steady hand.

Why Probate Disputes Happen

When someone passes away, their assets—homes, bank accounts, personal belongings, investments, and more—must be distributed. Ideally, a valid will sets clear instructions. But families often encounter complications, including:

  • Questions about whether a will ever existed —sometimes a will is lost, destroyed, or never finalized.
  • Disagreements over who should receive what —especially when promises were made verbally or expectations differ from what’s written.
  • Claims of undue influence —accusations that someone manipulated the deceased into changing their estate plan.
  • Concerns about capacity —family members may believe the person was not mentally capable of signing a valid will.
  • Suspicion of fraud or forgery —when a signature or document doesn’t appear authentic.

How Arizona Courts Handle These Conflicts

Arizona probate courts look at several factors to determine whether a will is valid. These include the signing requirements, the decedent’s mental state, and whether anyone exerted improper pressure. When a dispute arises, the court may require testimony, medical records, handwriting experts, financial documentation, or witness statements to sort out the truth.

If no valid will is found, Arizona’s intestacy laws decide who inherits. This often leads to unexpected results—and disagreements—because the statute may allocate assets differently than the family believes the decedent intended.
