Voter Registration Name Change in Montana

A voter registration name change in Montana is free and usually takes about five minutes. You will likely need to submit an updated paper registration form through the official Montana voter registration page.

Update your registration after your Montana driver's license shows your new name, since most registration forms ask for your current license number and the name on it.

Under the National Voter Registration Act ("motor voter"), updating your license at the Montana Motor Vehicle Division (MVD), a division of the Montana Department of Justice usually offers to update your voter registration at the same time. Say yes and you may not need a separate step at all.

One warning: don't assume it worked. Confirmation can lag by weeks, and a mismatch between your ID and the poll book is exactly the kind of surprise you don't want on election day. Verify on the official Montana page a couple of weeks after your DMV visit.

Regular voter registration (including name updates) closes 30 days before an election. During the final 30 days, "late registration" is allowed, but the voter must appear in person at the county election office to register/update and obtain a ballot, until noon the day before the election (until noon on Election Day for federal elections); no online update and no absentee ballot during that late window. The law: MCA 13-2-304 and MCA 13-2-301. Update well ahead of any upcoming election so your registration reflects your new name at the polls.

If an election is close and you've missed the update window, call your county election office. In many places you can still vote under your former name with your current registration, and some states offer same-day corrections. The rules vary, so ask before you skip voting.

• Your Montana driver's license or state ID (ideally already showing your new name)
• Your current residential address
• The last four digits of your Social Security number (some forms)

There is no fee to update voter registration in any state. This step is also a good prompt to update your name with your county property records and jury-duty notices, which pull from the same rolls.
