What Is Lewis and Clark County Criminal Records
Criminal records in Lewis and Clark County are official government documents that chronicle an individual's interactions with the criminal justice system, from initial law enforcement contact through final court disposition. These records are maintained by multiple agencies across the county and state, each responsible for a distinct segment of the criminal justice process.
Members of the public should understand the key distinctions among record types:
- Arrest records vs. conviction records: An arrest record documents that law enforcement took an individual into custody; it does not indicate guilt. A conviction record reflects a formal finding of guilt by a court of law.
- Felony vs. misdemeanor: Felonies are serious offenses punishable by more than one year of incarceration under Montana law, while misdemeanors carry lesser penalties, typically up to one year in a county jail.
- Adult vs. juvenile records: Adult criminal records are generally accessible to the public. Juvenile records are routinely sealed pursuant to Mont. Code Ann. § 41-5-215, which restricts disclosure to protect the privacy of minors involved in the justice system.
- Active warrants vs. historical records: Active warrants reflect current judicial orders for an individual's arrest, while historical records document past proceedings that have been resolved.
