Arizona Probate Court System: Estates, Guardianship, and Conservatorship

Arizona's probate court system governs the legal administration of decedents' estates, the appointment of guardians for incapacitated adults and minors, and the establishment of conservatorships over protected persons' financial affairs. Jurisdiction rests with the Superior Court in each of Arizona's 15 counties, operating under the Arizona Probate Code codified at Arizona Revised Statutes (A.R.S.) Title 14. These proceedings touch a wide range of Arizonans — from families managing inherited property to physicians and social workers documenting incapacity for court petitions.

Definition and scope

Arizona probate encompasses three distinct legal tracks, each with separate procedural rules and evidentiary standards under A.R.S. Title 14.

Estate administration addresses the collection, management, and distribution of a decedent's property. The Arizona Probate Code distinguishes between testate succession (death with a valid will) and intestate succession (death without a will), with intestate distribution rules set out in A.R.S. § 14-2101 through § 14-2114.

Guardianship is the court-supervised legal relationship in which a guardian is appointed to make personal decisions — including medical, residential, and educational decisions — for an individual found to lack capacity. Guardianship of adults is governed by A.R.S. § 14-5301 through § 14-5316, while guardianship of minors falls under A.R.S. § 14-5201 through § 14-5214.

Conservatorship covers the appointment of a fiduciary to manage the financial assets and property of a protected person. Unlike guardianship, conservatorship does not grant authority over personal or medical decisions; its scope is strictly financial and is regulated under A.R.S. § 14-5401 through § 14-5433.

Scope and limitations of this page: The content here covers Arizona state probate proceedings governed by A.R.S. Title 14 and administered in Arizona Superior Courts. It does not address federal estate tax law (governed by the Internal Revenue Code), tribal probate proceedings on federally recognized tribal lands (which operate under separate sovereign authority), or multi-state probate ancillary proceedings involving property held in other states. Arizona's Arizona Tribal Courts operate distinct probate frameworks outside the scope of A.R.S. Title 14.

How it works

Arizona probate proceedings follow structured procedural phases that vary by track.

Estate administration phases:

1. Filing the petition — The applicant files a petition for either informal or formal probate at the Superior Court in the county where the decedent was domiciled at death. Informal probate is an administrative process handled by the Registrar without a court hearing; formal probate requires a judicial order and a hearing.
2. Appointment of personal representative — The court or Registrar appoints a personal representative (executor) who is issued Letters Testamentary or Letters of Administration, granting legal authority to act on behalf of the estate.
3. Notice and creditor period — Under A.R.S. § 14-3801, the personal representative must publish notice to creditors, who then have 4 months from the date of first publication to file claims against the estate.
4. Inventory and appraisal — Assets are inventoried and appraised at fair market value as of the date of death.
5. Payment of debts and taxes — Valid creditor claims, funeral expenses, and applicable state and federal taxes are satisfied before distribution.
6. Distribution and closing — Assets are distributed to beneficiaries or heirs according to the will or intestate statutes, and the estate is formally closed.

Guardianship and conservatorship proceedings require a petition filed in Superior Court, service of process on the proposed ward or protected person, and a court hearing at which the petitioner bears the burden of demonstrating incapacity or financial vulnerability by clear and convincing evidence. The court is required under A.R.S. § 14-5303 to appoint a court investigator and, in adult guardianship matters, an attorney for the respondent if none has been retained. The Arizona Superior Court in each county maintains its own local rules that supplement A.R.S. Title 14 procedures.

The Arizona Judicial Branch publishes standardized probate forms available at no cost through the court's self-service center resources, which reduces filing barriers for unrepresented parties navigating the process.

Common scenarios

Arizona probate filings arise across predictable factual patterns.

Small estate affidavit: When a decedent's personal property does not exceed $75,000 and real property does not exceed $100,000 in equity (as set by A.R.S. § 14-3971 and § 14-3972), heirs may collect assets using a notarized affidavit rather than opening a formal probate proceeding. This is the most commonly used probate shortcut in Arizona.

Intestate estate with disputes: When a decedent leaves no will and multiple heirs contest the distribution of real property, formal probate is initiated to obtain judicial resolution. Arizona's community property framework under A.R.S. § 25-211 intersects with intestate succession rules, particularly for surviving spouses. For a fuller treatment of property ownership rules, see Arizona Community Property Law.

Emergency temporary guardianship: Under A.R.S. § 14-5310, a court may appoint a temporary guardian for up to 6 months upon a showing of imminent risk to an incapacitated adult. Emergency petitions can be filed and heard within 24 to 48 hours in most Arizona counties.

Minor guardianship after parental death or incapacity: When both parents die or are adjudicated incapacitated, a relative or other interested party petitions for appointment as guardian of the minor. This proceeding is distinct from dependency court proceedings, which are governed by A.R.S. Title 8 and addressed separately at Arizona Dependency Court.

Contested conservatorship: Adult children or other family members sometimes dispute whether a proposed protected person lacks the capacity to manage finances. The court may appoint a guardian ad litem and require independent medical or psychological evaluation before issuing a conservatorship order.

Decision boundaries

Probate jurisdiction is not unlimited and operates alongside competing legal frameworks.

Probate vs. non-probate transfer: Not all property passes through probate. Assets held in revocable living trusts, accounts with designated beneficiaries (such as IRAs, 401(k)s, or payable-on-death bank accounts), jointly held property with right of survivorship, and life insurance proceeds paid to named beneficiaries transfer outside of probate entirely. Arizona's probate system at the /index of the legal services landscape functions as a default mechanism for assets that lack these non-probate transfer mechanisms.

Guardianship vs. conservatorship: These two appointments are frequently confused. Guardianship governs the person; conservatorship governs the estate. The court may appoint the same individual to both roles or different individuals, and limited forms of each appointment — restricting authority to specific decisions — are explicitly permitted under A.R.S. § 14-5304 and § 14-5401.

Informal vs. formal probate:

Probate court vs. family court: Guardianship of minors whose parents are alive but deemed unfit may cross into family court jurisdiction under A.R.S. Title 25 or dependency court under Title 8. Jurisdiction depends on whether parental rights are implicated, whether the Department of Child Safety is involved, and whether the proceeding is consensual. The Arizona Family Law Courts page outlines parallel proceedings that may intersect with minor guardianship matters.

Fiduciary duty standards: Personal representatives, guardians, and conservators are all subject to a fiduciary duty of loyalty and prudence. The Arizona Supreme Court and the Arizona State Bar maintain oversight of attorneys acting in fiduciary capacities, and the probate court retains ongoing supervisory jurisdiction over conservatorships until formally discharged.
