Ind. Code § 3-10-5-7

Sec. 7. Nomination of a candidate for delegate to a convention held under this chapter must be by petition. Before the candidate's name is placed on a petition, the candidate must file in the office of the circuit court clerk of the county in which the candidate resides a declaration stating the candidate's name, the candidate's residence address with the street and number (if any), and whether if elected as a delegate the candidate will vote for or against the ratification of the amendment to be considered by the convention. The circuit court clerk may not accept a petition containing the name of a candidate who has failed to file such a declaration.
