What the law does ​

  • Requires the Secretary of State to implement and offer county elections officials a system for electronic signature curing.
  • Requires the electronic service to protect voters’ data privacy and security.
  • Requires the Secretary of State to publish county-level data on electronic curing offers and use.
  • Allows the electronic curing system to be combined with existing ballot-status and ballot-tracking systems.

Who it affects ​

  • Vote-by-mail voters whose ballot envelopes lack a signature or have a signature that does not match records.
  • County elections officials.
  • The Secretary of State.
