Montana Expungement: What to Know Before You Start

Start with the right legal category

“Expungement” is often used to describe several different record issues. In Montana, the general statutory process in Title 46, chapter 18, part 11 applies to eligible misdemeanor convictions. Marijuana-related relief can follow a separate statute and procedure. The first question is what the record actually shows, not what a background check or memory calls it.

An expungement order does not simply erase every practical question. It directs covered agencies and courts to seal or expunge records addressed by the order. The exact conviction, court, and history still matter when evaluating what relief may be available.

Misdemeanor expungement has real limits

Under MCA § 46-18-1104, a person convicted of one or more misdemeanors may petition, but may use that statutory process only once in a lifetime. The petitioner must also be fingerprinted to confirm identity. A petition may be filed in a district court in a judicial district where the person was convicted of a misdemeanor included in the request.

A five-year period without a new conviction after completing sentencing terms, including financial obligations and court-ordered treatment, can create a presumption in favor of expungement. That is not the same as an automatic expungement. The court still makes the decision.

Some convictions receive closer review

For certain offenses, including assault, partner or family member assault, stalking, sexual assault, protective-order violations, and DUI-related offenses, expungement is not presumed under MCA § 46-18-1108. That does not mean every request fails. It means the court evaluates the individual record without the statutory presumption.

In those cases, the law directs the court to consider the petitioner’s age at the offense, time since the offense, rehabilitation, likelihood of reoffending, and other relevant factors. That is why records showing completion of sentence, stability, treatment, work history, and the passage of time can matter.

The petition needs a complete paper trail

The petition must be served on every prosecution office that handled an offense included in the request. The prosecution and a victim who appears have an opportunity to respond. The court decides the request by a preponderance of the evidence, and the rules of evidence do not apply in the expungement hearing.

Start with the charging and disposition documents, sentence, proof of completion, case numbers, and current criminal-history information. The court cannot assess a request clearly if the underlying record is incomplete or the requested relief is vague.

Marijuana-related records are different

Some marijuana convictions may qualify for expungement, resentencing, or redesignation under separate Montana law. The facts, date, offense, sentence, and court matter. It is not safe to assume that a general misdemeanor rule answers a marijuana-record question.
