Step 4 — Cross-check before relying on data
Most county portals lag 24-48 hours behind the courthouse. For time-sensitive verification, call the clerk directly.

What's the difference between sealing and expunging a record in Montana?
In Montana, a sealed record is hidden from public view but still exists and remains visible to law enforcement, licensing boards, and some employers. An expunged record is treated by Montana law as if it never happened — though FBI and federal records may persist regardless of state action. The relief process runs through the sentencing court.

What's the difference between a court record and a criminal record in Montana?

Court records are searched by case; criminal records by person.
