Generally revise laws related to voter list maintenance

SB 439 would require Montana courts and the Department of Motor Vehicles (DMV) to share voter address changes with county election administrators. It mandates annual verification of voter addresses by comparing registration lists to national address change files and utility company data, sending confirmation notices to voters with outdated addresses. Voters who don’t respond to these notices would be moved to an inactive list until they confirm their address, with all processes needing completion 90 days before federal elections. The bill directly affects voter registration maintenance procedures across Montana, aiming to improve list accuracy by integrating data from multiple state agencies. (Note: The bill died in committee in May 2025 and did not become law.)
