Roads & Utilities
ROADS & TRANSPORTATION
Roads: I-94 serves Hysham, the county seat and only incorporated town in the county, along the Yellowstone River in southeastern Montana.
Notes: Treasure County, split from Rosebud County on February 7, 1919 and deliberately named “Treasure” as a strategy to attract new settlers, is genuinely Montana’s second-least-populous county (roughly 720-770 residents) and its fourth-smallest by land area (984 square miles).
Business & Permits
BUILDING & PERMITS
Office: Treasure County – confirm current phone via treasurecountymt.gov.
Notes: Treasure County holds a genuinely significant piece of Montana’s earliest recorded history: the first fur trading fort in what would become Montana, Fort Raymond (also called Fort Manuel Lisa), was built in 1807 by trader Manuel Lisa at the confluence of the Yellowstone and Bighorn Rivers within present-day Treasure County. Hysham itself grew after the area was ceded from the Crow Indian Reservation and opened to homesteading in 1906. The Yucca Theatre, built in 1931 by brothers David and Jim Manning in an unusual Mission/Southwestern architectural style for Montana, is NRHP-listed; David Manning’s father, Dave Manning, was genuinely the longest-serving state legislator in U.S. history, serving under 11 different Montana governors over 53 years. The Treasure County Museum occupies a historic building that once served as the county jail.

About Treasure County County
Treasure County is one of Montana’s least populous counties – a Yellowstone River valley cattle ranching community where Hysham serves fewer than 700 residents on the longest undammed river in America between Billings and Miles City.
Hysham (the county seat, population ~270) is Treasure County’s governmental hub on I-94, a small south-central Montana Yellowstone River community whose cattle ranching economy, river access, and courthouse serve the county’s sparse ranching population.

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
Treasure County Clerk of District Court, Probate Division 307 Rapelje Avenue (mail: P.O. Box 392), Hysham, MT 59038 (406) 342-5547
Treasure County was split off from Rosebud County in 1919, in south-central Montana, seated in Hysham. It is Montana’s second-least populous county. Treasure County is part of the 16th Judicial District, along with Carter, Custer, Fallon, Garfield, Powder River, and Rosebud counties.
Step 1: figure out which path applies
Montana adopted the Uniform Probate Code (UPC), codified at Title 72 of the Montana Code Annotated (MCA). Probate is handled by the District Court in the county where the decedent resided.
Collection of Personal Property by Affidavit (MCA § 72-3-1101) – available when the value of the probate estate, less liens and encumbrances, does not exceed $100,000. At least 30 days must have passed since the death, and no application or petition for appointment of a personal representative may be pending or granted anywhere. The affiant presents the sworn, notarized affidavit (with a certified death certificate) directly to whoever holds the property to collect it – skipping probate court entirely. Must be used within 3 years of death.
Summary Administration – a streamlined court process for estates valued at $100,000 or less; unlike the affidavit procedure, this still goes through the court, just with reduced formality.
Informal Probate – the most common path for uncontested estates. An application can be made to the clerk of district court no sooner than 120 hours (5 days) after death, with minimal court involvement.
Formal Probate – required when there’s no will, when a will’s validity is contested, or when there’s disagreement over the personal representative or distribution. Handled by a district court judge.
Supervised Administration – formal probate with ongoing court oversight of the personal representative.
Step 2: filing for formal or informal probate
File an application (informal) or petition (formal) with the Clerk of District Court in the county where the decedent resided, no sooner than 120 hours after death.
The court or clerk appoints the personal representative and issues Letters Testamentary or Letters of Administration.
The personal representative publishes notice to creditors and gives direct notice to known creditors. Creditors generally have 4 months from the date of first publication to file claims.
The personal representative inventories and appraises the estate’s assets.
After debts, taxes, and expenses are paid and the creditor claim period expires, the personal representative distributes the remaining assets and closes the estate.
What it costs
Montana does not set statutory percentage-based fees; personal representative and attorney fees are generally “reasonable compensation” based on time and complexity.
Montana has no state estate tax and no state inheritance tax. Only the federal estate tax could apply, and only to very large estates.
