To be a write-in candidate, a person must file a declaration of intent (Form 13, or for independent joint candidates for president and vice president, Form 13-A). Only write-in candidates who have filed a declaration of intent will have votes counted in the primary or general election (R.C. 3513.041). A write-in candidate must meet all of the eligibility requirements of the office. (See specific office for qualifications.)
Write-in candidates for statewide office and *independent joint candidates for president and vice president must file their declaration of intent with the Secretary of State. All other write-in candidates must file with the appropriate county board of elections.
A declaration of intent to be a write-in candidate in the primary election must be filed not later than 4 p.m. 62 days before the primary election. A declaration of intent to be a write-in candidate in the general election must be filed not later than 4 p.m. 62 days before the general election. (R.C. 3513.041) A write-in candidate must pay the same filing fee as any other candidate for the office. (See office filing fees under office of interest). (R.C. 3513.10 (A) and (B))
If the write-in candidate files for the primary election, the candidate must receive at least the same amount of write-in votes on the primary ballot as the "Candidate Signature Requirements" require to advance to the general election ballot.
* Note: A slate of 21 presidential electors must be filed with petitions.
