Ind. Code § 29-1-16-4
Accounts rendered to the court by a personal representative shall be for a period distinctly stated and shall consist of three (3) schedules, of which the first shall show the amount of the property chargeable to the personal representative; the second shall show payments, charges, losses and distributions; the third shall show the property on hand constituting the balance of such account, if any. When an account is filed, the personal representative shall also file receipts for disbursements of assets made during the period covered by the account. Whenever the personal representative is unable to file receipts for any disbursements, the court may permit him to substantiate them by other proof. The court may provide for an inspection of the balance of assets on hand. The court may, upon its own motion, or upon petition, provide that verification of accounts or credits thereon may be made by the unqualified certificate of a certified public accountant in lieu of receipts or other proof.
