Montana Expungement: One of the Broadest Laws in the Country

Most expungement guides are about limitation: who cannot qualify, which offenses are excluded, how long you have to wait. Montana is different. The state's 2019 expungement law — § 46-18-1101 et seq. MCA — is genuinely broad. A single petition can cover your entire criminal history. Felonies that would be permanently excluded in other states can be expunged in Montana. The waiting period is just five years. If you have a criminal record and you live in Montana, you are likely much closer to a fresh start than you realize.

What makes Montana's 2019 law different

Before 2019, Montana had a very limited expungement law — primarily covering only certain misdemeanor offenses. The 2019 reform changed that dramatically. Here is what makes the current law stand out:

• One petition covers your entire criminal history — you do not file separate petitions for each conviction. One petition, one process, potentially covering decades of arrests and convictions
• No limit on the number of prior offenses — unlike states that limit you to one or two expungements, Montana has no cap on how many convictions a single petition can address
• Many violent felonies are eligible — Montana allows expungement of a broad range of felonies that most states permanently exclude
• Five-year waiting period applies uniformly — the same wait for misdemeanors and most felonies
• You file in your county of residence — not in the county of conviction — which is more convenient if you have moved since your conviction

Who qualifies — and who does not

Montana's eligibility is broad, but not unlimited. The law specifically excludes certain serious offenses regardless of time passed or conduct since conviction.

The 5-year waiting period — and how it works with multiple convictions

Montana's 5-year waiting period runs from the date your most recent sentence was completed. If you have multiple convictions, the clock runs from the end of the most recent one — not from each individual conviction.

This means: if you have convictions from 2010, 2015, and 2020, and you completed your sentence on the 2020 conviction in 2022, you can petition in 2027 — and that one petition can include all three convictions.

The one-petition system — how to use it effectively

Montana's one-petition rule is both the law's biggest advantage and something that requires careful thought before you file.

The advantage: you can clear your entire history in one filing. No repeat petitions, no multiple court processes in multiple counties. One petition, potentially clearing everything.

The consideration: be thorough. List every conviction you want cleared in your petition. If you leave something out and try to come back later, Montana's statute may limit your ability to refile for the same offenses. Take time before filing to make sure your petition is complete.

What expungement does in Montana

When Montana grants expungement, the effect is significant:

• The conviction is removed from public criminal history records
• You may answer "no" on most employment and housing applications that ask about prior convictions — Montana law permits this after expungement
• The Montana Department of Justice Criminal Records Bureau updates the state criminal history within 30 days of the order
• Each law enforcement agency listed in the petition is notified and required to update their records

What Montana expungement does not cover

The filing process, step by step

Montana expungement petitions are filed in the district court of your county of residence — not the county of conviction. If you have lived in Montana your whole life and your convictions were all in one county, this is the same court. But if you have moved since your conviction, you file where you live now.

Fees and fee waivers

Filing fees in Montana vary by district court. Expect to pay between $75 and $200. If the fee is a financial hardship, Montana courts can waive fees for people who qualify based on income. Ask the clerk for a fee waiver application when you go to file.

If you have convictions in multiple counties, you still file one petition in your county of residence and pay one filing fee. The court then handles notification to the county attorneys in other counties. You do not pay separate fees for each county.

Out-of-state convictions — a note

Montana's expungement law covers Montana convictions only. If you have convictions from other states, those records are not affected by a Montana expungement petition. You would need to pursue expungement or sealing in each state where the conviction occurred, under that state's laws.

This is worth knowing upfront. If a background check company is reporting convictions from multiple states, a Montana expungement will clear the Montana entries but the out-of-state entries will remain. Know your full record before you file so you can plan accordingly.

Montana's law in national context

Most expungement guides describe the limitations. Montana's law is worth understanding in context because it is genuinely more generous than the national norm. Many states limit expungement to one or two offenses, exclude any violent offense, and require 10-year or longer waiting periods even for misdemeanors.

Montana's 2019 reform came from a recognition that permanent, unresolvable records undermine rehabilitation and public safety. People who cannot find housing or employment are more likely to reoffend. The legislature chose a different path. If you are a Montana resident, that choice creates a real opportunity for you — one that does not exist in most states.
