Montana Title 46, Chapter 18: Sentences, Conditions, and Enhancements

Title 46, Chapter 18 of the Montana Code Annotated is the state’s sentencing statute. It is what a Montana judge works from after a guilty plea or verdict: the menu of sentences available, the conditions and financial obligations that can be attached, the enhancements that apply to repeat offenders, and the procedures for reviewing, revoking, or clearing a sentence later. Montana sentencing law under Title 46, Chapter 18 spans eleven parts covering deferred and suspended sentences, persistent felony offender provisions, credit for time served, home arrest, and misdemeanor expungement.¹

The Sentences a Judge Can Impose

MCA 46-18-201 sets the main options. Which one the court selects depends on the offense, the defendant’s record, and the limits built into each option.²

Deferred Imposition of Sentence

With a deferred sentence, the court holds off on imposing punishment. The defendant complies with conditions, and if they do, they can petition to have the charge dismissed and the record cleared. The standard deferral runs up to one year for a misdemeanor and up to three years for a felony. When a financial obligation like restitution is part of the conditions, those maximums extend to two years for a misdemeanor and six years for a felony.²

There’s a significant limit. A person with a prior felony conviction generally cannot get a deferred sentence for a new felony. The option is largely available to first-time felony defendants and to misdemeanor cases.

Suspended Sentence

A suspended sentence works differently. The judge actually imposes a prison or jail term and then suspends its execution, so the defendant doesn’t serve the time as long as they comply with supervision conditions. The suspension can last up to the maximum sentence allowed for the offense, or six months, whichever is greater.² If the defendant violates, the court can activate the original term without a new sentencing proceeding.

Incarceration and Commitment to the Department of Corrections

For direct incarceration, the judge orders time in a county detention center or state prison based on what the underlying offense statute allows. Commitment to the Department of Corrections is a separate path, with the department deciding placement in a correctional facility or program; all but the first five years of such a commitment must be suspended. The court can also place an offender in a community corrections facility or prerelease center for up to one year, subject to the receiving program’s approval and available space.²

Conditions and Restrictions on a Sentence

MCA 46-18-202 lets the court attach conditions beyond the core sentence. These can include prohibiting the defendant from holding public office, banning them from owning or carrying a dangerous weapon, restricting their associations, limiting travel, or imposing any other condition reasonably tied to rehabilitation and victim protection.³

For prison sentences over one year, the court can declare the defendant ineligible for parole or supervised release. The judge must put the reasons in writing and find the restriction necessary for public protection. For certain sex offenses, the court can also strip the defendant’s eligibility for good-time credit, effectively requiring every day of the imposed term to be served.³

Restitution, Surcharges, and Public Defender Costs

Montana judges must order full restitution to any victim who suffered a financial loss from the crime. Under MCA 46-18-241, this obligation stays with the offender or the offender’s estate until paid in full, whether or not the person is still under state supervision. Restitution payments are a mandatory condition of any probation or parole.⁴

Restitution covers the full replacement cost of property taken or destroyed. The state has to prove the link between the crime and the claimed loss by a preponderance of the evidence. The court looks at the defendant’s income, debt, and living expenses to set a realistic payment schedule. If an offender genuinely cannot pay, the court can order community service credited at the state minimum wage per hour worked.

Several additional financial obligations are standard. Every misdemeanor or felony conviction under Montana’s criminal code triggers a $50 per-charge surcharge that funds victim and witness advocacy programs.⁵ Courts of limited jurisdiction impose a separate $10 surcharge on each criminal conviction.⁶ Defendants who used a public defender may also be ordered to pay the cost of that representation. Under MCA 46-8-113, those costs are $250 for a misdemeanor guilty plea and $800 for a felony guilty plea. If the case went to trial, the defendant may owe the actual costs the public defender’s office incurred. The court can only impose these fees after finding the defendant able to pay, and the obligation is suspended during any period of incarceration.

Failure to keep up with court-ordered payments can trigger a petition to revoke a suspended or deferred sentence. That’s why the payment schedule set at sentencing needs to reflect the defendant’s real financial capacity.

Before the Sentence: The Presentence Report and Hearing

In most felony cases, a probation and parole officer prepares a presentence investigation report. Under MCA 46-18-111, the district court can order the investigation after a guilty plea, verdict, or finding of guilt, and the judge must consider the findings before sentencing.⁷ The report covers a validated risk and needs assessment, criminal and social history, the circumstances of the offense, and the harm to the victim, along with any documented financial loss. Both sides receive the completed report before the sentencing hearing.

At the hearing itself, under MCA 46-18-115, the court first lets both sides address any relevant issue, including whether mandatory minimums or enhancements apply. The defense can challenge inaccuracies in the presentence report, and the judge must resolve those disputes on the record before moving forward.⁸

The defendant has the right to speak directly to the judge before the sentence is announced. The court must personally ask whether the defendant wants to make a statement or present anything that might justify a lighter sentence. Victims have a parallel right to be heard, through a written statement before the hearing, sworn testimony at the hearing, or both. The judge must share any written victim statement with both sides before imposing sentence. If a victim’s statement introduces new facts the court plans to rely on, the defendant must get adequate time to respond, and the court can continue the hearing if necessary.⁸

In felony cases, the judge must state all reasons for the sentence on the record in open court and in the written judgment. That includes the specific terms of any incarceration, the length and conditions of supervision, and the rationale for any enhancements or restrictions.

Enhancements for Repeat Offenders

Persistent Felony Offender

Part 5 of Chapter 18 contains Montana’s persistent felony offender provisions. Under MCA 46-18-501, a person qualifies if they have a prior felony conviction (including out-of-state convictions carrying a possible sentence of more than one year), the current offense was committed within five years of either the prior conviction or release from custody for it, and the prior hasn’t been pardoned on innocence grounds or set aside.

A persistent felony offender who was at least 21 at the time of the current offense faces a prison term of 5 to 100 years, a fine of up to $50,000, or both. The first five years cannot be deferred or suspended.⁹

The numbers get steeper if the person was already classified as a persistent felony offender at the time of the earlier conviction and the new offense falls within five years of that conviction or release. The mandatory minimum then jumps to 10 years, the ceiling stays at 100, and the first 10 years cannot be deferred or suspended. That sentence must also run consecutively to any other sentence the person is already serving.⁹

Mandatory Life for Repeat Violent and Sexual Offenses

MCA 46-18-219 is separate from the persistent felony offender framework. It imposes mandatory life imprisonment without the possibility of release for certain repeat violent and sexual offenders. A person convicted of deliberate homicide, aggravated kidnapping, sexual abuse of children, ritual abuse of a minor, or aggravated sexual intercourse without consent, who has a prior conviction for any of those same offenses, must receive a life sentence.¹⁰

A second tier applies to offenses like mitigated deliberate homicide, aggravated assault, strangulation of a partner or family member, kidnapping, robbery, and child sex trafficking. Two prior convictions from that list, from the first list, or any combination, trigger mandatory life imprisonment. An offender sentenced under this provision must serve the entire term in prison, cannot be paroled, cannot earn good-time credit, and cannot be transferred to any non-prison facility except for medical reasons. The sentence cannot be deferred or suspended.¹⁰

Credit for Time Already Served

Under MCA 46-18-403, anyone who spent time in jail before sentencing gets a day-for-day credit against the final prison or jail term. The incarceration has to be directly related to the proceedings that led to the sentence, so time held on an unrelated matter doesn’t count. The credit also cannot exceed the length of the sentence imposed.¹¹

The specific number of credit days must appear in the written judgment. Errors here affect the actual release date, and correcting them later requires a motion to amend the judgment. Defense attorneys usually verify the count independently rather than relying on the court’s calculation.

What Happens If Conditions Are Violated

When someone violates the conditions of a suspended or deferred sentence, the prosecution can file a petition for revocation under MCA 46-18-203. The petition has to be filed while the suspension or deferral period is still active. Once filed, the offender must be brought before the court without unnecessary delay and no more than 60 days after arrest.¹²

The offender is entitled to at least 10 days’ notice before the hearing and must be told the specific allegations, the right to present evidence, the right to question adverse witnesses, and the right to an attorney. At the hearing, the prosecution must prove the violation by a preponderance of the evidence. That is a lower standard than the “beyond a reasonable doubt” threshold used at trial.¹²

If the court finds a violation, it has options. It can continue the sentence unchanged, modify the conditions, place the offender in a secure facility or community corrections program for up to nine months, or, for serious violations, revoke the suspension or deferral entirely and impose the original prison term.

Sentence Review After Sentencing

The Montana Supreme Court has a Sentence Review Division that reviews prison sentences of one year or more. A defendant sentenced to at least one year in state prison, or committed to the Department of Corrections for that length, can file an application for review within 60 days of sentencing. If an appeal or post-conviction petition is also pending, the 60-day clock starts when that proceeding concludes.¹³

A person serving a suspended or deferred sentence under community supervision is not eligible, and neither is someone committed to the Montana State Hospital. The division’s decisions are final, with no further appeal.¹³

Home Arrest as an Alternative

Part 10 of Chapter 18 authorizes home arrest in place of incarceration. Under MCA 46-18-1004, people convicted of violent felonies are not eligible, nor are people being held under a detainer, warrant, or process from another jurisdiction. The statute does allow monitoring devices as part of intensive supervision programs run by the Department of Corrections, even when formal home arrest wouldn’t otherwise be available.¹⁴

Expunging a Montana Record

Part 11 addresses expungement, and the scope is narrower than most people assume. Under MCA 46-18-1104, a person convicted of one or more misdemeanors can petition a district court to expunge all records of arrest, investigation, detention, and court proceedings related to those offenses. The petition can cover misdemeanors from multiple courts and multiple cases.¹⁵

A person can only petition for misdemeanor expungement once in a lifetime, and the petitioner must be fingerprinted to verify identity. Felony convictions are not eligible under this part of the code. A deferred felony sentence that ends in dismissal results in the charge being cleared through the deferral itself, not through the expungement statute.
