Arizona County
Santa Cruz County, Arizona
Nogales - the busiest land port of entry for produce in the United States - from Nogales's extraordinary trade significance (the twin cities of Nogales, Arizona and Nogales, Sonora form one of the most commercially significant border crossings in North America - over half of all fresh fruits and vegetables imported into the United States enter through Nogales, making it the produce gateway for the entire country) to the Patagonia-Sonoita wine country (the high grassland valleys of Santa Cruz County - at 4,000-5,000 feet elevation with rich volcanic soils and distinct monsoon seasons - support Arizona's most productive wine grape growing region, with dozens of wineries producing nationally recognized vintages) and Tumacacori National Historical Park.

About Santa Cruz County
Santa Cruz County is Arizona’s produce gateway and wine country county – more than half of America’s imported fresh fruits and vegetables enter through Nogales, and the high grassland valleys support one of the Southwest’s most acclaimed wine regions.

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 Santa Cruz County Superior Court.
Record the certified affidavit with the Santa Cruz 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 Santa Cruz 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.
