Allows voter to cure mail-in ballot due to certain envelope deficiencies or missing certificate, and to vote by provisional ballot following receipt of cure letter.

This bill allows New Jersey voters to correct mail-in ballots with certain envelope or certificate issues instead of having them automatically disqualified. It specifically covers situations where the ballot wasn't properly enclosed in the inner envelope, the certificate wasn't signed, the envelope was missing or unsealed, or the seal appeared tampered with. Voters who receive a "cure letter" about these issues can either submit a corrected ballot or vote in-person using a provisional ballot during early voting or on election day. This expands current law that only permitted curing for signature-related issues. The bill requires county election officials to send cure letters with clear instructions on how to fix the problem or vote provisionally.
