Bonneville Salt Flats - where land speed records are broken - from the Bonneville Salt Flats (the 30,000-acre expanse of perfectly flat salt crust west of the Great Salt Lake - the remnant of the ancient Lake Bonneville that once covered much of Utah - where every major land speed record in history has been set, from Ab Jenkins's 1930s marathon runs to the ThrustSSC's 763 mph supersonic record attempt nearby - the Bonneville Speedway's measured mile on the salt is the most famous racing surface in the world) and Dugway Proving Ground (the 800,000-acre restricted military testing range - larger than Rhode Island - where the US Army has tested chemical, biological, and radiological weapons and defenses since 1942 in one of the most secretive military installations in the United States).

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Third District Court, Tooele County 74 South 100 East, Suite 14, Tooele, UT 84074 (435) 833-8000
Tooele County is in Northern Utah, west of Salt Lake City, seated in Tooele. Utah has NO separate probate court – probate is handled by the District Court. Tooele County is part of the Third Judicial District (Salt Lake, Tooele, and per some sources Summit), seated in Salt Lake City.
Step 1: figure out which path applies
Utah has adopted the Uniform Probate Code (Title 75, Utah Uniform Probate Code) in full – one of about 16 states to do so. This makes Utah’s probate process comparatively streamlined.
Small Estate Affidavit (Utah Code § 75-3-1201) – available when the total estate value (minus liens and encumbrances) is $100,000 or less AND the estate includes NO real property. At least 30 days must have passed since death. This is a true affidavit process – it is NOT filed with the court. The successor fills it out, signs it before a notary, and presents it directly to whoever holds the property (a bank, brokerage, employer, etc.), which is then legally obligated to release the asset. A separate, similar affidavit can transfer title to up to four boats, motor vehicles, trailers, or semi-trailers directly through the Utah Division of Motor Vehicles.
Informal Probate – the most common track in Utah under the UPC. Minimal court involvement; a probate registrar (not a judge) reviews the application and appoints the personal representative administratively when there’s no dispute.
Unsupervised Formal Probate – involves a judge and a court hearing to resolve a specific question (such as confirming a will’s validity) but otherwise proceeds with the same independence as informal probate afterward.
Supervised Formal Administration – full ongoing court supervision, reserved for contested, complex, or high-conflict estates.
Step 2: filing for administration
The personal representative (or an interested party) files an Application for Informal Probate and Appointment of Personal Representative with the Third District Court.
The original will (if one exists) and a certified death certificate are submitted with the application.
The court registrar reviews the application; if in order, Letters Testamentary (with a will) or Letters of Administration (without one) are issued – often without a hearing.
The personal representative provides notice to creditors and known heirs, and inventories the estate’s assets.
The personal representative pays valid debts, expenses, and taxes from the estate.
Remaining assets are distributed to beneficiaries or heirs, and the estate is closed.
What it costs
District court filing fee: $375 statewide (confirm current fee for Tooele County directly, as fees can be adjusted).
Utah has NO statutory fee schedule for attorneys or personal representatives – fees must be “reasonable” based on time spent, complexity of the estate, and its value.
Small estate affidavit proceedings cost far less since no court filing is required at all – mainly notary and any professional assistance fees.
Utah does NOT impose a state estate tax or inheritance tax. Only the federal estate tax may apply, and only to very large estates.
