How Much Does Guardianship Cost in Arizona

The Real Cost Is Higher Than the Filing Fee

Most families budget only for the court filing fee and then discover a cascade of mandatory expenses they never anticipated. Arizona's guardianship process involves filing fees, a court-appointed investigator fee, fingerprint processing, certified copies of letters you will need for every bank and hospital, and potentially thousands in attorney fees. The total out-of-pocket cost for an uncontested guardianship ranges from roughly $600 to over $5,000 depending on your county, whether you hire an attorney, and whether the petition is contested.

Court Costs by County

Arizona's filing fees are set by state statute but modified by local county surcharges. Following Administrative Order 2024-210 (effective December 28, 2024), all Superior Court filing fees increased by 18% statewide.

These are the mandatory court-related costs alone — no attorney, no document preparation service.

Attorney Costs

If you hire an attorney, expect to pay $300–$500 per hour for a probate or special needs attorney in the Phoenix or Tucson metro areas. A straightforward, uncontested guardianship typically runs $2,500–$5,000 in total attorney fees. If the petition is contested — meaning someone objects to the guardianship or to you as the proposed guardian — costs can climb to $10,000 or more as the case moves to an evidentiary hearing.

The court also appoints an independent attorney for the proposed ward, whose fees are billed to the ward's estate or, if the ward has no assets, may be borne by the petitioner. The court-appointed attorney and investigator fees together routinely add $1,000–$2,500 to the process.

Ways to Reduce Costs

Self-filing. Arizona allows you to file a guardianship petition without an attorney. Maricopa County's Law Library Resource Center provides free self-help form packets, and the Arizona Supreme Court publishes standardized petition forms (Packet AOCPBGCA11F) online. Self-filing eliminates attorney fees entirely but requires you to navigate court procedures, serve notice correctly, and represent yourself at the hearing.

Fee waivers and deferrals. If the proposed ward (or the petitioner) meets income thresholds, you can apply for a court fee waiver or deferral that reduces or eliminates filing fees and investigator costs. The application requires documentation of income and assets.

Combined petitions. If you need both guardianship and conservatorship, file them together in a single petition rather than separately. This consolidates the filing fee and the hearing into one proceeding.

Consider alternatives first. A supported decision-making agreement, healthcare power of attorney, and financial power of attorney together cost nothing beyond a notary fee (typically under $25 total) and provide broad coverage for families whose young adult has the capacity to sign voluntarily. If these tools are sufficient, the entire court process — and its costs — can be avoided.

Ongoing Annual Costs

The expenses do not end at appointment. Guardians must file an Annual Report on the Condition of the Ward (no filing fee). Conservators must file an annual financial accounting, which may incur post-judgment filing fees of $87–$102 in Maricopa County. If the court required a surety bond, the annual bond premium adds another recurring cost based on the ward's estate value.
