Signature requirements, the 180-day rule, and the circulator technicalities that decide Michigan petitions.
Michigan requires petitions for nearly every office, with only a narrow $100 fee alternative. It is also one of the most technically demanding petition states in the country — several of its rules void an entire sheet rather than a single signature, and campaigns have been removed from the ballot over vendor misconduct they had no knowledge of.
| Office / Measure | Requirement |
|---|---|
| Statewide, major party | 15,000 min / 30,000 max, including at least 100 electors in each of at least 7 congressional districts |
| Statewide, no party affiliation | 12,000 min / 60,000 max (court-ordered figure), same district distribution |
| U.S. Representative, major party | Population-based; commonly 1,000 min / 2,000 max |
| U.S. Representative, independent | 3,000 / 6,000 |
| State Senator | 500 / 1,000 major party — 1,500 / 3,000 independent |
| State Representative | 200 / 400 major party — 600 / 1,200 independent |
| Ballot initiative — constitutional amendment | 446,198 (10% of last gubernatorial vote) |
| Ballot initiative — state statute | 356,958 (8%) |
| Veto referendum | 223,099 (5%) |
Every signature must be collected within the 180 days immediately preceding filing. Older signatures are invalid, and for candidate petitions the Bureau of Elections treats this as absolute. The same 180-day window applies to ballot measure petitions.
Circulators must be 18 or older and U.S. citizens. They need not be Michigan residents, registered voters, or district residents; the residency requirement was eliminated in 2014. But a circulator who is not a Michigan resident must check the nonresident box on the circulator certificate, accepting Michigan jurisdiction. If that box is left unchecked, every signature on that sheet is invalid. It is one of the highest-consequence technicalities in the country.
The circulator must personally sign and date the certificate after collecting signatures, and the circulator's date may not precede any signer's date. Paid circulators are permitted, including pay-per-signature, but must disclose paid status on the form. Petition sheets are not notarized, though the candidate's Affidavit of Identity must be.
Michigan prescribes the physical petition form: 8.5 by 14 inch paper, "NOMINATING PETITION" in 24-point boldface, the warning in 12-point boldface, remaining text in 8-point. Nonconforming forms are rejected outright.
Michigan is comparatively generous on signer-side errors. A missing printed name, ZIP code, street address, or date does not invalidate a signature so long as the signature itself is present. Illegible signatures, ditto marks, and initials plus a last name are all acceptable. Filing officials are directed to presume signatures genuine and resolve ambiguities in favor of the voter.
Michigan has a robust citizen initiative process. Thresholds are set as a percentage of the total vote for Governor at the last gubernatorial election: 10% for constitutional amendments, 8% for initiated statutes, 5% for veto referendum. Circulation is limited to 180 days. There is no geographic distribution requirement — a 2018 law attempting to cap signatures at 15% per congressional district was struck down by the Michigan Supreme Court in January 2022. An initiated statute goes to the legislature first; if it is not enacted within 40 session days, it goes to voters.
It varies by office and party status. Statewide major-party candidates need 15,000 to 30,000, including at least 100 from each of seven congressional districts. Statewide independents currently need 12,000 under a federal court order. State house candidates need 200 to 400 for major party, 600 to 1,200 as an independent.
Yes. Michigan eliminated its circulator residency requirement in 2014. However, a nonresident circulator must check the nonresident box on the circulator certificate, accepting Michigan jurisdiction. If it is left unchecked, every signature on that sheet is invalidated.
180 days. Every signature must be collected within the 180 days immediately preceding filing, for both candidate and ballot measure petitions.
For statewide candidate petitions, yes — at least 100 signatures from each of at least seven congressional districts. For ballot measures, no. The Michigan Supreme Court struck down an attempted distribution cap in 2022.
Signature requirements are the easy part. Hitting them on deadline is the job.
