Indiana Code Title 29. Probate § 29-1-10-13

Sec. 13. If a testator by will makes provision for the compensation of his personal representative, that shall be taken as his full compensation unless he files in the court a written instrument renouncing all claims for the compensation provided by the will before qualifying as personal representative.  The personal representative, when no compensation is provided in the will, or when he renounces all claim to the compensation provided in the will, shall be allowed such compensation for his services as the court shall deem just and reasonable.  Additional compensation may be allowed for his services as attorney and for other services not required of a personal representative.  An attorney performing services for the estate at the instance of the personal representative shall have such compensation therefor out of the estate as the court shall deem just and reasonable.  Such compensation may be allowed at the final settlement;  but at any time during administration a personal representative or his attorney may apply to the court for an allowance upon the compensation of the personal representative and upon attorney's fees.
