Any time a voter moves from county to county or state to state, that voter will need to re-register to vote in their new county/state of residence. If a voter is already registered and moves to a new residence located in the same county, that voter will need to update their registration, preferably before the day of the election. A voter can update their registration by completing a voter registration form and sending it to the County Clerk’s Office. If you’re currently registered in the county and move to a new home in the same county, you can fill out the back of your voter registration card and submit it to the office.
The deadline to register if you move to another County in Missouri is 28 days prior to the election. You may change your address (in the current county you reside in) at any time.
Voting in a county or precinct therein that does not represent your current residence on the day of the election is a violation of Missouri statute and is prosecutable by law.
