Indiana Code Title 36. Local Government § 36-7-17-8

Sec. 8. Before the vesting of a fee simple title in the purchaser, any material failure by the purchaser to carry out the agreement entered into under section 6 of this chapter nullifies the agreement and all right, title, and interest in the property immediately reverts to the agency, except that the agency may grant the purchaser a specified period, not to exceed two (2) years, to come into compliance with the terms of the agreement.  The agency may subordinate its interest under the terms of the agreement to financial institutions or persons lending money to the purchaser for the purpose of allowing the purchaser to fulfill the terms of the conveyance.
