No. Politely decline and ask for an attorney. Montana Highway Patrol, Division of Criminal Investigation, sheriffs, and city police use trained interrogation. Anything you say is admissible. Invoke your Fifth Amendment right to silence and Mont. Const. Art. II, § 25 right against self-incrimination.

Yes. Montana misdemeanors carry up to 6 months or 1 year in county jail depending on the offense, plus fines. Deferred imposition of sentence under MCA § 46-18-201 can result in dismissal and expungement for many misdemeanors. DV and DUI convictions trigger major collateral consequences.

State cases go through Montana District Court (felonies) or Justice Court / City Court (misdemeanors). Federal cases go to U.S. District Court for the District of Montana (Billings, Great Falls, Missoula, Helena, Butte) under the U.S. Sentencing Guidelines. Federal cases in Montana commonly involve drug trafficking, federal land/park offenses (Glacier National Park, Yellowstone, federal forests), Indian Country / federal Major Crimes Act jurisdiction on Native reservations, and § 922(g) firearm cases.

Montana plea agreements under MCA § 46-12-211 are negotiated between the County Attorney and defense. Pleas can include charge reductions, deferred imposition of sentence (MCA § 46-18-201 — uniquely valuable — completion = dismissal/expungement), drug court entry, mental health court entry, and stipulated sentence recommendations.

Yes — Montana expanded expungement in 2017 under MCA § 46-18-1101 et seq. Misdemeanors are eligible after 5 years post-completion. Deferred imposition completions result in dismissal and automatic expungement. Felony expungement remains narrow (limited to certain non-violent first-time offenses through specific procedures).

Montana handles juveniles under 18 in Youth Court under MCA § 41-5-101 et seq. Records are confidential. Most juvenile records are automatically sealed upon termination of jurisdiction (typically age 18) under MCA § 41-5-216. Transfer to adult District Court for juveniles 12+ for serious offenses under § 41-5-206 et seq.

Montana DUI under MCA § 61-8-401 uses .08 BAC (.04 commercial, .02 under-21). Implied consent under § 61-8-402 — refusal triggers automatic 6-month license suspension first time. Mandatory IID for repeat offenders and high-BAC first offenses under § 61-8-1006. Fourth DUI is a felony.

Why Do You Need a Criminal Defense Attorney in Montana?

Montana grades crimes under MCA § 45-2-101 et seq. — most felonies carry statute-specific maximums (commonly 5, 10, 20, or 100 years; life for the most serious). Deliberate Homicide (MCA § 45-5-102) carries 10-100 years, life imprisonment, or death (Montana retains the death penalty though it has not been actively imposed in many years). The Persistent Felony Offender designation under MCA § 46-18-501 enhances sentences — defendant with one prior felony in 5 years faces 5-100 year exposure; the recidivist provisions are layered. Montana legalized recreational marijuana in 2020 (Initiative 190, eff. January 2022) — adults 21+ can possess up to 1 oz cannabis flower; medical marijuana since 2004. Montana’s deferred imposition of sentence (MCA § 46-18-201) is uniquely valuable — court can defer imposition for up to 3 years (felony) with eligibility for dismissal and expungement upon successful completion. Montana’s expungement statute under MCA § 46-18-1101 et seq. allows misdemeanor expungement after 5 years (broadened in 2017) and deferred sentence expungement upon dismissal. Montana County Attorneys plea-bargain extensively; many counties offer drug court, mental health court, and veterans treatment court.

Misdemeanors and most felonies are flat-fee; complex cases use hourly billing. The Montana Office of State Public Defender represents indigent defendants statewide.
