Montana Arrest Records & Inmate Lookup

About arrest records in Montana

In Montana, arrest records are primarily generated and maintained at the county sheriff level. When an individual is taken into custody anywhere in Montana, they are typically booked into the county jail of the county where the alleged offense occurred. That booking creates the official arrest record — capturing the arrestee's name, date of birth, the arresting agency, the booking date and time, the formal charges filed, the bond amount set by a magistrate, and (in most counties) a booking photograph.

From there, records branch into several streams. The county sheriff's office maintains the jail roster — the live list of currently incarcerated individuals at the county detention facility. The clerk of court for the county logs the resulting criminal case once charges are formally filed, including all hearings, motions, and dispositions. If a person is convicted and sentenced to state prison time, custody transfers to the Montana state department of corrections, which publishes its own inmate locator separate from the county jail roster.

ArrestVault organizes all of this jurisdiction-by-jurisdiction. Below you'll find a directory of all 56 Montana counties and county-equivalents. Each county page explains where to find local arrest logs, how to look up current inmates, what the booking process looks like in that jurisdiction, and how to access the underlying court records.
