The Signature Is the Sticking Point
The single most scrutinized part of your mail-in ballot is your signature. Kansas is a signature verification state, meaning election officials compare the signature on your ballot envelope to the one they have on file from your voter registration. If they don’t appear to match, your ballot can be challenged and potentially rejected. Signatures can change over time due to age, injury, or simple haste, creating discrepancies that can disenfranchise a voter. While state law requires officials to contact the voter to "cure" or fix the issue, the process and timeline can vary by county, adding a layer of uncertainty. Pro-voting groups have challenged the state’s signature matching laws, arguing the process can be error-prone and lacks uniform standards
across its 105 counties.
Racing Against the Clock
Even a perfectly filled-out ballot will be rejected if it arrives too late. For years, Kansas had a three-day grace period, allowing ballots postmarked by Election Day to be counted if they arrived within three days after. However, this rule has been the subject of intense legal and political battles. In 2025, a law was passed to eliminate this grace period, requiring ballots to be in the hands of election officials by 7 p.m. on Election Day. Courts have since intervened, temporarily blocking that law and reinstating the grace period for recent elections, but the situation has created confusion. Because of the legal uncertainty, officials have urged voters not to wait until the last minute and to return their ballots as early as possible to avoid being disenfranchised by postal delays outside of their control.
Simple, Preventable Errors
Beyond signatures and deadlines, a surprising number of ballots are rejected for basic administrative mistakes. This category includes ballots returned without a signature on the affidavit envelope, a common and easily avoidable error. Voters must sign the envelope for the ballot to be considered valid. Other issues can include failing to provide required identification information on the application for the ballot in the first place. To even receive a mail ballot, voters must provide their driver's license number or a copy of another accepted photo ID. In rare cases, administrative errors at the county level, such as printing an incorrect return address on ballot envelopes, have also caused ballots to be returned to voters instead of being counted.
Navigating the 'Cure' Process
When an election official finds a missing or mismatched signature, it doesn't always mean immediate rejection. Kansas law provides a "cure" process, giving voters a chance to fix the problem. If an issue is flagged, the county election office is supposed to contact the voter by mail, informing them of the discrepancy and providing instructions on how to verify their identity or correct the signature. Voters can then fix the issue in person at the election office, or sometimes by fax or email. However, advocates have noted that the uniformity and effectiveness of this process can differ significantly from one county to another, meaning a voter's opportunity to have their ballot counted could depend on their zip code.
