Indiana Code Title 27. Insurance § 27-2-13-3

Sec. 3. (a) When an insurer has reason to believe that a fire loss in which it has an interest was caused by a means that was not accidental, then, for the purpose of notification and for having that fire loss investigated, the company shall, in writing, notify an authorized agency and provide that agency with all material developed from the insurer's inquiry into the fire loss.

(b) When an insurer provides an authorized agency with notice of a fire loss, it shall be considered sufficient notice for the purpose of this chapter.  However, the insurer shall provide the state fire marshal a copy of the information provided under subsection (a), if the notice was provided to an authorized agency other than the state fire marshal.
