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.

S 4835 allows New Jersey voters to correct mail-in ballots with certain envelope issues instead of having them rejected. The bill expands the current process (which only permitted curing for signature issues) to include cases where voters failed to insert ballots in inner envelopes, didn't sign certificates, or had missing/unsealed envelopes. If a ballot is rejected for these reasons, county election offices must send a "cure letter" within 24 hours, giving voters 48 hours before non-general election results are certified (or 11 days after general elections) to either submit a corrected ballot or vote in-person using a provisional ballot. This change aims to prevent legitimate votes from being lost due to minor technical errors.
