Indiana Code Title 29. Probate § 29-1-17-14

Sec. 14. (a) If, after an estate has been settled and the personal representative discharged, other property of the estate shall be discovered, or if it shall appear that any necessary act remains unperformed on the part of the personal representative, or for any other proper cause, the court, upon the petition of the discharged personal representative or any person interested in the estate and, without notice or upon such notice as it may direct, may order that said estate be reopened.  It may reappoint the personal representative or appoint another personal representative to administer such property or perform such act as may be deemed necessary.  Unless the court shall otherwise order, the provisions of this article as to an original administration shall apply to the proceedings had in the reopened administration so far as may be, but no claim which is already barred can be asserted in the reopened administration.

(b) Except as provided in section 13.5 of this chapter, whenever any solvent estate has been closed, and it thereafter appears that any assets thereof have not been fully administered upon, the court may, if it appears practicable, order such assets distributed to, or title vested in, the persons entitled thereto in lieu of reopening the estate as provided in the preceding subsection.  No additional notice of such proceedings shall be necessary unless so ordered by the court.
