Indiana Code Title 32. Property § 32-29-7-4

Sec. 4. (a) A sheriff shall offer to sell and sell property on foreclosure in a manner that is reasonably likely to bring the highest net proceeds from the sale after deducting the expenses of the offer and sale.

(b) Upon prior petition of the debtor or any creditor involved in the foreclosure proceedings, the court in its order of foreclosure shall order the property sold by the sheriff through the services of an auctioneer requested by the petitioner and approved by the court if:

(c) The sheriff shall engage the auctioneer not later than fourteen (14) calendar days after the date of the order entered by the court under subsection (b).  The auctioneer shall schedule the auction and conduct the auctioneer's activities as appropriate to bring the highest bid for the property on foreclosure.  The advertising conducted by the auctioneer is in addition to any other notice required by law.

(d) The auctioneer's fee must be a reasonable amount stated in the court's order.  However, if the sale by use of an auctioneer has not been agreed to by the creditors in the proceedings and the sale price is less than the amount of the judgment and the costs and expenses necessary to the satisfaction of the judgment, the auctioneer is entitled only to the auctioneer's advertising expenses plus one hundred dollars ($100).  The amount due the auctioneer on account of the auctioneer's expenses and fee, if any, shall be paid as a cost of the sale from its proceeds before the payment of any other payment from the sale.
