Concerning effective voter notifications and forms.

SB 5902 amends Washington state election laws to clarify and standardize voter registration and address update deadlines. It requires voters to submit registration or address changes by eight days before an election (or in person until 8:00 p.m. on election day), and expands methods for updates - including mail, phone, email, DMV, health exchange, or designated agencies. The bill mandates counties to send acknowledgment notices within 60 days for new registrations and handle incomplete applications by requiring missing information within 45 days. It directly affects all Washington voters needing to register or update their address for elections.
