1. If the voter files a change of address application in person at the office of the election authority, at the polling place, or pursuant to section 115.159, 115.160, 115.162 or 115.193, or otherwise provides signed written notice of the move, including notice by facsimile, electronic, or online transmission, an election authority may change the address on a voter registration record for a voter who moves within the election authority’s jurisdiction after comparing and verifying the signature. Before changing the address on a voter record, the election authority shall be satisfied that the record is that of the person providing the change of address information.

2. A registered voter who has changed his or her residence within an election authority’s jurisdiction and has not been removed from the list of registered voters pursuant to this chapter shall be permitted to file a change of address with the election authority or before an election judge at a polling place and vote at a central polling place or at the polling place that serves his or her new address upon written or oral affirmation by the voter of the new address.

3. A registered voter who has changed his or her residence within the state and has not been removed from the list of registered voters under this chapter shall be permitted to file a change of address in person at the office of the election authority on election day. In order to change an address in person on election day under this subsection, a registered voter shall provide a form of personal photo identification required under subsection 1 of section 115.427.

4. If the applicant for registration was last registered in another jurisdiction within this state or another state, the election authority shall send notice of the registration to the election authority where the applicant was previously registered. The election authority sending the notice shall provide identifying information to assist the election authority receiving the notice to determine whether the person named was previously registered in such jurisdiction and whether, based on the identifying information provided, the application can be removed from the voting record in the former jurisdiction.

5. Upon receipt of a notice from another election authority that a voter has registered in another jurisdiction in this state or another state, the election authority shall determine whether sufficient information is provided in the notice to identify the person named in such notice as previously registered in the election authority’s jurisdiction and presently removable from the voting records in the election authority’s jurisdiction. Every election authority is authorized to examine the information provided in a notice of duplicate registration provided by the Missouri voter registration system authorized pursuant to section 115.158 to determine if a voter in one election authority’s voter registration records has subsequently registered in another jurisdiction. If, after reviewing the information provided, the election authority is satisfied that the person identified in the notice is listed as a registered voter in the election authority’s jurisdiction but has subsequently registered in another jurisdiction, the election authority may remove the person’s registration from the list of registered voters.
