The bill amends Chapter 17-20 of the General Laws concerning mail ballots, introducing new requirements to enhance accessibility for voters unable to sign due to blindness, disability, or inability to read or write. It stipulates that these voters or their assistants must indicate their condition on the mail ballot application and provide relevant information about the assistant. Additionally, the bill allows mail ballot applications received within three days after the standard deadline to be considered valid if delivered by postal service. It also clarifies definitions related to voting and emphasizes that a voter's signature can be represented by a mark under certain conditions, reinforcing penalties for false applications or certifications.

Key changes include the removal of the requirement for voters unable to sign to use an "X," allowing them or their assistants to mark a box instead. The bill mandates that the full name, residence address, and signature of the assistant be included on the certifying envelope. It also establishes a three-day transmittal period for accepting mail ballot applications post-deadline and requires electronic applications through the voter registration portal. The bill outlines the certification process for applications and the issuance of ballots, ensuring that the secretary of state provides necessary information to political parties and candidates while correcting undeliverable ballots. The act will take effect upon passage.
