Montana Criminal Defense Attorneys

A criminal charge in Montana plays out differently than almost anywhere else. The state's deferred imposition of sentence can turn a guilty plea into a dismissal and an expunged record, while a Persistent Felony Offender designation can multiply your exposure many times over. Voters legalized recreational marijuana through I-190, and the 2017 expungement expansion opened doors that used to be shut. From District Court in Billings or Missoula to Justice Courts in Great Falls, Bozeman, and Kalispell — and across all 56 counties — DearLegal matches you with a Montana defense attorney who knows this terrain, free to start.

Don't. Be polite, decline, and ask for a lawyer. Montana Highway Patrol, the Division of Criminal Investigation, sheriffs, and city police are all trained interrogators, and everything you say can be used against you. You hold both a Fifth Amendment right to silence and a separate protection against self-incrimination under Mont. Const. Art. II, § 25 — invoke them.
Almost always. Depending on the offense, a Montana misdemeanor can mean up to 6 months or 1 year in county jail plus fines — and DUI or domestic violence convictions carry collateral consequences that follow you for years. A lawyer can also pursue deferred imposition of sentence under MCA § 46-18-201, which for many misdemeanors ends in dismissal and expungement.
State felonies run through Montana District Court, with misdemeanors in Justice Court or City Court. Federal cases land in the U.S. District Court for the District of Montana — courthouses in Billings, Great Falls, Missoula, Helena, and Butte — where the U.S. Sentencing Guidelines apply. Federal prosecutions here often involve drug trafficking, offenses on federal land (Glacier National Park, Yellowstone, the federal forests), Indian Country cases under the Major Crimes Act on the reservations, and § 922(g) firearm charges.
Your attorney negotiates directly with the County Attorney, and the agreement is governed by MCA § 46-12-211. Deals can include reduced charges, stipulated sentence recommendations, entry into drug court or mental health court, and — often the best outcome available — deferred imposition of sentence under MCA § 46-18-201, where completing the deferral means dismissal and expungement.
Often, yes. Montana broadened expungement in 2017 through MCA § 46-18-1101 et seq. Misdemeanors become eligible 5 years after you complete your sentence, and a finished deferred imposition results in dismissal and automatic expungement. Felony expungement is still narrow — limited to certain non-violent first-time offenses through specific procedures.
Montanans under 18 go through Youth Court under MCA § 41-5-101 et seq., where records are confidential. Most juvenile records are automatically sealed when the court's jurisdiction ends — typically at age 18 — under MCA § 41-5-216. The serious risk is transfer: juveniles 12 and older charged with serious offenses can be moved to adult District Court under § 41-5-206 et seq.
Tough and escalating. The limit under MCA § 61-8-401 is .08 BAC (.04 for commercial drivers, .02 if you're under 21). Implied consent under § 61-8-402 means refusing a test triggers an automatic 6-month license suspension the first time. Repeat offenders and high-BAC first offenders face mandatory ignition interlocks under § 61-8-1006, and a fourth DUI is a felony.

Why Do You Need a Criminal Defense Attorney in Montana?

Montana doesn't use a simple felony-class ladder. Crimes are graded under MCA § 45-2-101 et seq., and most felonies carry statute-specific maximums — commonly 5, 10, 20, or 100 years, with life for the most serious offenses. Deliberate Homicide (MCA § 45-5-102) carries 10-100 years, life imprisonment, or death; Montana retains the death penalty even though it has not been actively imposed in many years. Repeat offenders face the Persistent Felony Offender designation under MCA § 46-18-501 — a defendant with one prior felony in 5 years faces 5-100 year exposure, and the recidivist provisions are layered on top of each other. On the other side of the ledger, Montana offers real off-ramps. Deferred imposition of sentence (MCA § 46-18-201) is uniquely valuable: the court can defer imposition for up to 3 years on a felony, and successful completion brings eligibility for dismissal and expungement. The expungement statute, MCA § 46-18-1101 et seq., was broadened in 2017 and now allows misdemeanor expungement after 5 years, plus expungement of deferred sentences upon dismissal. Marijuana is legal too — voters passed Initiative 190 in 2020 (effective January 2022), letting adults 21+ possess up to 1 oz of cannabis flower, on top of medical marijuana dating to 2004. County Attorneys plea-bargain extensively, and many counties run drug courts, mental health courts, and veterans treatment courts. A defense lawyer who knows which doors to push is the difference between a record and a clean slate.

Common Montana Criminal Defense Mistakes

Even a small misstep can hurt your case. Here’s what to avoid:

How Much Do Montana Criminal Defense Attorneys Cost?

Flat Fee

Most matters are billed as a flat fee per petition or filing — fee depends on case complexity.

You won't find contingency arrangements in Montana criminal cases — they're barred by Mont. R. Prof. Conduct 1.5(d) and ABA Model Rule 1.5(d). Instead, expect a flat fee for misdemeanors and most felonies, with hourly billing reserved for complex matters. Defendants who can't afford counsel are represented statewide by the Montana Office of State Public Defender.

What Can Your Montana Criminal Defense Compensation Include?

Charge Dismissal
Won through suppression motions, motions to dismiss for insufficient evidence, the speedy trial guarantee of Mont. Const. Art. II, § 24 (which the Montana Supreme Court enforces robustly), or a County Attorney's own motion to dismiss.
Charge Reduction
Dropping a felony to a misdemeanor, stepping a higher-penalty felony down to a lower one, or stripping out Persistent Felony Offender allegations or a firearm enhancement.
Deferred Imposition of Sentence
Under MCA § 46-18-201, the court accepts a guilty plea but defers imposing sentence for up to 3 years — finish successfully and the case is dismissed and expunged. Drug court, mental health court, and veterans treatment court offer parallel paths.
Plea Agreement
A negotiated resolution under MCA § 46-12-211: reduced charges, dismissed counts, recommended sentences, or probation instead of incarceration.
Trial Acquittal
A not-guilty verdict from a Montana judge or jury. Felony juries seat 12, misdemeanor juries seat 6, and verdicts must be unanimous (Mont. Const. Art. II, § 26).
Post-Conviction Relief
A petition under MCA § 46-21-101, filed within the 1-year window from finality, raising ineffective assistance, newly discovered evidence, an illegal sentence, or constitutional violations.
