AB 827 lays out a detailed, statewide process for how county elections officials must compare signatures on vote-by-mail identification envelopes and related cure statements. The bill specifies which signatures may be used for comparison, creates a presumption in favor of counting ballots, allows signature verification technology and facsimiles under regulation, and sets a multi-step cure and notification procedure before a ballot may be rejected.
The statute matters because it replaces local practice variation with uniform rules: it limits the factors officials may consider (for example prohibiting consideration of party, race, or most identifying details), defines when ballots are deposited versus when they are held for further review, sets concrete notification and receipt deadlines that vary by election type, requires public posting of county procedures, and authorizes use of a combined correction form and secure electronic submission options. Those elements change operational workflows for county election offices, signature-technology vendors, voter assistance organizations, and legal teams that advise them.
At a Glance
What It Does
Requires elections officials to compare a vote-by-mail signature to the signature on the voter’s registration record (affidavit of registration or an official signature form), presumes the ballot is valid unless clear, significant discrepancies exist, permits signature verification technology and facsimiles, and establishes a cure process with specific notice and receipt deadlines.
Who It Affects
County elections officials (procedure, notice, and reporting duties), the California Secretary of State (rulemaking and a statewide combined form), signature-verification technology vendors, organizations that assist voters with curing ballots, and voters who return vote-by-mail or unsigned identification envelopes.
Why It Matters
AB 827 reduces local variation in signature review and raises the evidentiary bar for rejecting ballots (requiring two additional officials to find a mismatch beyond a reasonable doubt), while adding new operational responsibilities and evidentiary questions around the use of technology and facsimile signatures.

What This Bill Actually Does
AB 827 creates a step-by-step standard for handling signatures on vote-by-mail envelopes and related cure statements. When a county receives a vote-by-mail ballot, the elections official must compare the signature on the identification envelope to the signature in the voter’s registration record—either the affidavit of registration or an official signature form kept with the record.
The law clarifies that exact matches are unnecessary: sharing similar characteristics can be sufficient to accept a signature.
The bill builds a presumption that a ballot’s signature is the voter’s and that the vote will be counted. It simultaneously narrows what a reviewer may consider: officials may not take party preference, race, ethnicity, or most identifying details into account (except to confirm identity), and they may not be judged by how long they spent reviewing a signature.
Officials can, however, use regulated characteristics (slant, letter formation, printed vs cursive), facsimiles prepared lawfully, or signature-verification software — but any technology must be used consistent with Secretary of State regulations and triggers additional procedures if the technology reports a nonmatch.If a reviewer determines a signature has multiple, significant, and obvious differing characteristics from the registration-record signatures, the ballot is not immediately discarded. The statute requires two additional elections officials to independently find, beyond a reasonable doubt, that the signatures differ before rejecting the ballot.
If those officials determine the signatures do not compare, the county must provide specified written notice (and, if available, phone/text/email), in required languages, informing the voter how and by when to return a signature verification statement. The law prescribes the wording of notices and cure statements, allows combined forms produced by the Secretary of State or counties, and authorizes secure electronic submission methods so long as counties implement privacy and security protocols.The statute also addresses unsigned identification envelopes: it gives voters multiple cure pathways (returning a signed envelope, submitting an unsigned identification envelope statement, or delivering a statement in person before polls close) and directs counties to accept timely cures and to update the voter’s signature on file when a cure statement is received—even if it is returned after the deadline.
AB 827 includes operational rules—ballots stay in the identification envelope until processing time, an elections official must publish their signature-comparison procedures online, counties may use signature data for outreach, and defined notification/receipt deadlines differ between regular statewide elections and other contests—so administrators can convert the requirements into practice.
The Five Things You Need to Know
The bill creates a rebuttable presumption that the signature on the vote-by-mail identification envelope is the voter’s and that the ballot will be counted unless clear, significant discrepancies are found.
A ballot may be rejected for signature mismatch only after two additional elections officials each find beyond a reasonable doubt that the signature differs in multiple, significant, and obvious respects from the voter’s registration signatures.
For regularly scheduled statewide elections the statute sets the ‘applicable notification deadline’ at 14 days after the election and the ‘applicable receipt deadline’ at 22 days after the election; different, tighter deadlines apply for non-statewide contests tied to certification.
The law forbids officials from considering a voter’s party preference, race, ethnicity, or most identifying details (gender, name, or address) when comparing signatures, but permits consideration of regulated signature characteristics (slant, letter formation, cursive vs printed).
County elections officials must accept completed signature verification or unsigned identification envelope statements that meet the statute’s form requirements, may use a combined form published by the Secretary of State, and must update the voter’s signature on file from the cure statement when it is received.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Authorized source signatures and core comparison rules
This subsection specifies which signatures an elections official may use for comparison: the signature on the voter’s current or prior affidavit of registration or on an official signature form kept in the registration record. It establishes the central rules governing comparison: a presumption that the ballot signature is valid, no requirement of exact matches, allowance for signature characteristics as laid out by SOS regulations, and explicit prohibitions on considering party, race, ethnicity, and most identifying information except for confirming identity.
When ballots are deposited and the rejection threshold
If the official determines the signatures compare, the ballot remains in its identification envelope and is deposited in a ballot container. Conversely, if an initial reviewer finds multiple, significant, and obvious differing characteristics, the ballot is not rejected immediately; it is subject to an elevated review process requiring two additional elections officials to each conclude beyond a reasonable doubt that the signatures do not compare before the ballot is excluded and a reason for rejection is written on the envelope.
Notice, signature verification statement, and cure procedures
This long subsection prescribes the notice form and the signature verification statement that counties must use (including mandatory language and the jury-like ‘beyond a reasonable doubt’ rejection pause). Counties must mail first-class notice, include a postage-paid return envelope, and, where available, also notify by phone, text, or email. Notices must be translated into federally required languages and must specify the statutory receipt deadlines. The subsection authorizes voters to return cure statements by mail, fax, email, controlled electronic means, in person at polling places, or via drop boxes during the specified windows.
Unsigned identification envelopes and alternative cure paths
AB 827 treats missing signatures as curable: a voter can sign the identification envelope at the county office, submit an unsigned identification envelope statement by the statutory receipt deadline, or deliver that statement to a polling place or drop box before polls close. The county must notify the voter and accept timely-submitted statements, then compare the provided signature under the same standards; if accepted, the unsigned statement is attached to the envelope and the ballot is deposited.
Combined forms, online access, and electronic submission safeguards
The Secretary of State must publish a single combined signature verification/unsigned envelope statement that counties must make available online. Counties must accept the combined form and provide their mailing and electronic contact information. If a county offers electronic submission, it must implement privacy and security protocols to ensure submissions are received directly and used only for verification, placing a new compliance burden on counties that opt into digital cures.
Processing rules, timing definitions, and adherence to SOS regulations
The bill requires ballots remain inside identification envelopes until processing time and forbids rejecting a ballot for cause after the envelope has been opened. It defines ‘applicable notification’ and ‘receipt’ deadlines differently for statewide versus other elections (14/22 days post-election for regular statewide contests; tighter deadlines tied to certification for other contests) and mandates that signature comparisons, including use of software, follow Secretary of State regulations.
Contact authority, procedure publication, form restrictions, dropbox use, and holiday rule
Counties may use contact information from a voter’s registration to notify them for cures, and must post any local signature-comparison procedures online. Counties may accept only forms developed by the Secretary of State or by elections officials (not third-party forms). If a county uses a post-election drop box at its office for receiving cure forms, it must label it clearly for that limited purpose. Finally, statutory deadlines that fall on holidays are not deferred to the next business day, an uncommon timing rule that tightens some cure windows.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Voters with signature variation (older voters, those with disabilities, or people whose signatures change over time): the statute presumes validity and explicitly recognizes variation in style and haste as permissible explanations, making wrongful rejections less likely.
- Voters who use marks or signature stamps: AB 827 presumes validity for signatures made by an “X” or signature stamp when they meet the requirements of Section 354.5, clarifying treatment of nonstandard signatures.
- Voter assistance organizations and county voter outreach teams: the law codifies cure pathways, allows secure electronic submission, and authorizes counties to use registration contact data, making organized cure efforts more straightforward and predictable.
- Secretary of State and counties seeking consistency: SOS rulemaking authority and the required combined form provide statewide standardization that reduces inter-county variation and legal uncertainty.
Who Bears the Cost
- County elections offices: the bill increases workload and administrative costs for individualized notices (mail, phone, text, email), multilingual translations, posting procedures online, operating post-election drop boxes for forms, and implementing secure electronic submission systems.
- Signature-verification technology vendors: vendors must ensure their products comply with Secretary of State regulations and counties’ posted procedures, and their outputs may trigger additional manual review processes that vendors must support.
- Nonprofits and third-party voter-assistance groups that previously used their own cure forms: the statute prohibits counties from accepting forms created by any private entity, limiting certain third-party operational support and forcing reliance on official forms.
- Legal teams and election litigators: the ‘beyond a reasonable doubt’ standard and subjective elements of signature comparison may spawn contested reviews and litigation over whether counties applied the statute or regulations correctly.
Key Issues
The Core Tension
AB 827 pits two legitimate priorities against one another: making it harder to wrongly disenfranchise voters by standardizing cures and presuming validity, versus preserving confidence in election integrity by preventing ineligible or fraudulent ballots—an aim that pushes administrators toward stricter, potentially more exclusionary verification practices. The statute tries to thread that needle, but its subjective standards and reliance on downstream SOS rulemaking leave the practical balance unresolved.
The statute resolves some problems of inconsistent local practice but replaces them with a set of interpretive and operational challenges. Key phrases—“similar characteristics,” “multiple, significant, and obvious differing characteristics,” and the requirement that two additional officials each find a nonmatch “beyond a reasonable doubt”—are analytically imprecise.
Counties will need detailed training programs and quality-control protocols to translate these subjective standards into repeatable decisions, and Secretary of State regulations will be pivotal in narrowing how characteristics and technology outputs are weighed.
The bill’s embrace of signature-verification technology and facsimiles creates implementation risks. Different vendors and versions of software can produce divergent results; the statute requires counties to follow SOS regulations but does not specify performance thresholds, error rates, or audit requirements for algorithms.
Similarly, the rule that counties must update a voter’s signature from a cure statement—even if received untimely—improves future comparisons but raises the risk that an incorrect or fraudulently obtained signature could become the new baseline. Finally, the prohibition on accepting non-official forms limits flexibility for community groups that assist voters and may reduce informal but effective local practices for helping voters cure ballots.
