Source Ledger - Arizona Probate Process

May 23, 2026

Probate is the court-supervised process by which a deceased person’s assets are inventoried, debts are paid, and remaining property is distributed to heirs. In Arizona, probate is administered through the Superior Court of each county, most often the Probate Division of the Maricopa County Superior Court for Phoenix-area estates.

The process applies when a person dies owning assets titled in their individual name without a transfer-on-death mechanism, a named beneficiary, or trust ownership. Assets that bypass probate (jointly held property with right of survivorship, accounts with named beneficiaries, real property covered by a Beneficiary Deed, and assets held in a Revocable Living Trust) move directly to the new owner without the court’s involvement.

Probate is often described as “going through the will.” That phrasing is misleading. The will does not avoid probate; the will is the document the court uses during probate to identify the deceased’s wishes. A will and probate are two parts of the same process, not alternatives.

Where the institution came from

The English ecclesiastical courts handled the probate of wills from the medieval period through the nineteenth century, treating wills and estate administration as matters of religious as well as civil concern. The Statute of Wills (1540) under Henry VIII formalized the right to dispose of real property by will and is generally considered the foundational legal moment for modern testamentary law. Subsequent English statutes through the eighteenth and nineteenth centuries refined the procedural framework that American colonial courts inherited.

Each American state adopted its own probate procedures after independence, leading to substantial variation in how estates were administered. By the mid-twentieth century, this variation had produced widespread inefficiency. In 1969, the National Conference of Commissioners on Uniform State Laws (now the Uniform Law Commission) drafted the Uniform Probate Code (UPC) as a model statute intended to simplify and standardize probate across jurisdictions.

Arizona was one of the early adopters. The Arizona Legislature passed the Arizona Probate Code in 1973, modeled closely on the UPC, with an effective date of January 1, 1974. The code is codified at Arizona Revised Statutes Title 14 and has been amended numerous times since, though its structural framework remains UPC-derived. Arizona is one of approximately eighteen states that have adopted the UPC in substantially complete form.

How it operates

Arizona probate has three procedural tracks, chosen based on estate complexity and family circumstances.

Informal probate is the default for most estates. The Personal Representative (the role most other states call “executor” or “administrator”) files an application with the court, receives Letters Testamentary (if there is a will) or Letters of Administration (if there is no will), and proceeds to administer the estate without ongoing judicial oversight. No hearings are required unless a dispute arises. Most Arizona estates settle through informal probate.

Formal probate involves court hearings and is used when the validity of the will is in question, when there are competing claims to the personal representative role, or when the estate is otherwise contested. A judge supervises the process more actively.

Supervised administration applies to estates where the court determines ongoing supervision is necessary. This is the least common track and is generally reserved for situations involving incapacitated beneficiaries, contested estates, or cases where the personal representative requires court approval for major decisions.

For small estates, Arizona provides a streamlined affidavit procedure. Estates with less than $75,000 in personal property and less than $100,000 in real property can be transferred through a Small Estate Affidavit rather than formal probate, provided certain conditions are met. The affidavit can be used 30 days after death for personal property and 6 months after death for real property.

The procedural timeline for a typical Arizona informal probate runs 6 to 18 months from filing to closure. The variability depends on creditor claims (Arizona requires a four-month publication notice period for unknown creditors), the complexity of the assets, the cooperation of beneficiaries, and the speed of asset liquidation if any is required.

Costs include the court filing fee (currently around $250 in Maricopa County), publication costs for the creditor notice (typically $100 to $300), attorney fees if counsel is retained (the most variable cost), Personal Representative compensation (statutorily authorized as reasonable, often 1 to 3 percent of the estate), and any accounting, appraisal, or bond costs the estate incurs. The widely cited figure of 3 to 7 percent of estate value as the total probate cost is a rough estimate that depends heavily on whether legal counsel is engaged and the complexity of the assets.

Why it is misunderstood

Three persistent misunderstandings shape how Arizona families think about probate.

The first is the assumption that having a will avoids probate. It does not. A will instructs the probate court on how to distribute assets but does not bypass the court process itself. Avoiding probate requires structures that move assets outside the probate estate (a Revocable Living Trust, a Beneficiary Deed for real property, beneficiary designations on accounts, joint tenancy with right of survivorship), not simply the existence of a will.

The second is the assumption that probate is uniformly expensive and adversarial. The UPC-derived Arizona system, particularly informal probate, is designed to be administrative rather than litigious. Most Arizona probate cases move through the court without a hearing. The cost burden is real but typically driven by attorney fees and complexity rather than by court fees or judicial intervention.

The third is the assumption that probate is private. Arizona probate filings are public court records. The will, the inventory of assets, the creditor claims, the personal representative’s accounting, and the final distribution are all accessible to anyone who searches the court records. For families who want privacy about the estate’s contents, this is one of the strongest reasons to use a Revocable Living Trust instead of relying on a will and probate.

Formal definition

The Arizona Probate Process is the court-supervised legal procedure, governed by Arizona Revised Statutes Title 14 and administered through the Superior Court of each county, by which a deceased person’s individually-titled assets are inventoried, debts and taxes are paid, and remaining property is distributed to heirs or beneficiaries.

COMMON MISUSE OR MISCONCEPTION

Conflated with “going through the will.” A will is the document the court uses during probate. Probate is the court process the will moves through. Having one does not eliminate the other.

Treated as inherently expensive. Arizona’s UPC-derived informal probate is administratively efficient by design. Costs scale with attorney involvement and estate complexity, not with the court process itself. Simple estates with cooperative heirs and low complexity can complete informal probate at modest cost. The widely cited “3 to 7 percent” figure is a rough average that conceals significant variation.

Assumed to be private. Arizona probate filings are public records searchable through the Superior Court of each county. Anyone can read the will, inventory, and accounting. Privacy is one of the primary reasons to use a trust instead of relying on probate.

Confused with estate tax administration. Probate handles state-level asset distribution and creditor claims. Federal estate tax filing (if required) is a separate process administered by the IRS. Most Arizona estates are not subject to federal estate tax (the 2026 exemption is in the millions), but estates that are still face that filing regardless of whether they go through probate.

Assumed to take years. The 6 to 18 month timeline cited in most explanations refers to typical informal probate. Contested estates, real estate sales, or out-of-state asset complications can extend the timeline considerably, but the baseline procedural period is shorter than many families expect.

Where this comes up in the series

The Legacy Blueprint course references probate in nearly every post, as the procedural cost that estate planning is largely designed to avoid or minimize.
