About Navajo County
Navajo County contains the largest concentration of Native American tribal land of any county in the United States – the Navajo Nation (the largest tribal nation by land area in the US, covering parts of Arizona, New Mexico, and Utah) and the Hopi Reservation (uniquely surrounded by the Navajo Nation) together cover the vast majority of the county’s 9,953 square miles. This extraordinary tribal land presence defines the county’s demographics, economy, governance, and estate planning landscape in ways unlike any other county outside Alaska.
The Navajo Nation – with a total area of 27,425 square miles across three states – is the largest Native American territory in the United States. Its government, the Navajo Nation Council, operates from Window Rock in Apache County (just across the border from Navajo County). The Nation has its own court system, law enforcement, schools, and services that operate in parallel with and sometimes in tension with county and state government.
The Hopi Reservation – an island of Hopi tribal land surrounded entirely by the Navajo Nation – is home to the Hopi people, whose mesa-top villages (including Old Oraibi, continuously inhabited since approximately 1100 CE and considered the oldest continuously inhabited settlement in North America) represent one of the oldest living cultures in the Western Hemisphere.
Petrified Forest National Park – where ancient logs have been replaced atom by atom with silica minerals over 225 million years, creating the world’s largest collection of petrified wood – straddles the Navajo County/Apache County boundary. The park is one of the few that visitors can exit through a different gate than they entered, allowing through-travel on I-40.
Show Low (population ~12,000) and Pinetop-Lakeside are the county’s primary resort and retirement communities on the Mogollon Rim – the dramatic escarpment where the Colorado Plateau drops thousands of feet to the lower deserts. Show Low is named for a card game – legend holds that two settlers played cards to determine who would get the land, with the winner being whoever could “show low.”
Holbrook (the county seat, population ~5,000) is a Route 66 town known for the Wigwam Motel – concrete tepee-shaped rooms that are a National Historic Landmark and one of Route 66’s most photographed roadside attractions.
County government is a five-member Board of Supervisors with a County Manager.

Courts & Legal
Courts & Legal
The Navajo County Superior Court at 100 E. Code Talkers Drive, Holbrook (928-524-4188) handles all civil, criminal, family, and probate matters for non-tribal matters. Tribal members on tribal land are subject to Navajo Nation Courts and/or Hopi Tribal Courts jurisdiction for many matters.
The Navajo County Recorder (928-524-4188) maintains fee land records. Tribal trust land records are maintained through the Bureau of Indian Affairs.
Tribal estate planning – dual jurisdiction: Navajo County residents who are enrolled Navajo Nation or Hopi Tribe members face dual-jurisdiction estate planning – tribal law governs trust land succession (which generally requires BIA approval for transfer), while Arizona law governs fee land and personal property. Working with attorneys experienced in both federal Indian law and Arizona probate law is essential.
Mogollon Rim vacation property: Show Low and Pinetop-Lakeside vacation home owners (most from the Phoenix metro escaping summer heat) need succession planning for Arizona fee land properties.
Senior Services: The Navajo County Health and Community Services – Area Agency on Aging (928-532-6041) at 411 E. Clay Street, Holbrook coordinates senior services, home-delivered meals, transportation, SHIP Medicare counseling, caregiver support, and connections to Arizona ALTCS programs.

Step 1: figure out which path applies
Arizona recently made this decision much easier for most families – a 2025 law dramatically raised the small-estate thresholds, so many more estates now qualify to skip full probate entirely.
Small Estate Affidavit (personal property) – no court case needed. Effective September 26, 2025 under House Bill 2116 (amending A.R.S. § 14-3971), this applies when personal property is worth $200,000 or less (net of liens), at least 30 days have passed since the death, and no probate case has been opened. Present the signed affidavit directly to the bank or institution holding the property.
Small Estate Affidavit (real property) – for real property with equity of $300,000 or less (net of liens), available after a 6-month wait. Must be filed with the Superior Court and then recorded with the County Recorder.
Informal Probate – the default track for uncontested estates above the small-estate thresholds. Reviewed by a court registrar, not a judge.
Formal Probate – used when the will is contested, there’s no original will, heirs are disputed, or the matter otherwise needs judicial involvement.
Supervised Administration – rare; used only when ongoing court oversight is needed to protect the estate or beneficiaries.
Arizona is a community property state – a surviving spouse already owns their half of community property outright.
If using the small estate affidavit (personal property)
Wait at least 30 days after the death.
Confirm no probate case has already been opened and total personal property (net of liens) is $200,000 or less.
Complete the affidavit under A.R.S. § 14-3971.
Present the signed affidavit with a certified death certificate directly to whoever holds the property.
If using the small estate affidavit (real property)
Wait at least 6 months after the death.
Confirm the real property’s equity is $300,000 or less.
File the affidavit with the Navajo County Superior Court.
Record the certified affidavit with the Navajo County Recorder.
If filing informal probate
Gather the original will (if any), a list of assets/debts/heirs, and identifying information.
File an Application for Informal Probate and Appointment of Personal Representative with the Clerk of the Superior Court.
Notice to known heirs must comply with A.R.S. § 14-3306.
The registrar reviews the application; if complete and unopposed, issues Letters Testamentary or Letters of Administration – no hearing required.
Notice to creditors must be published once a week for three consecutive weeks in a newspaper of general circulation in the county.
Creditors then have a 4-month claim window (A.R.S. § 14-3801) – the practical floor on how fast even a simple probate can close; most run 6–12 months.
After debts are resolved, the personal representative distributes the estate and closes it with a final accounting.
If formal probate is required
File a Petition for Formal Probate with the Superior Court.
A judge holds a hearing rather than a registrar reviewing on paper.
The same inventory, creditor-notice, and closing steps apply from there, under direct court supervision.
What it costs
Small estate affidavits: no court filing fee for the personal-property affidavit; the real-property affidavit carries a county recording fee.
Informal or formal probate filing fee: varies by county, typically $250–$400 statewide (confirm current fee with the Navajo County Clerk).
Creditor notice publication: typically $75–$300 depending on the newspaper.
Personal representative compensation: “reasonable compensation” standard – no fixed statutory percentage.
Attorney fees: not fixed by statute; a straightforward, uncontested probate commonly runs $2,000–$7,500.
