§ 11-503

(a) Except in Harford County, if a sheriff is required to sell real or personal property as part of his official duties, he may employ an auctioneer of his choice and charge the costs of the sale to the debtor.

(b) If the Sheriff of Harford County employs an auctioneer, the debtor is primarily liable, but if the proceeds of the sale are insufficient to cover the costs, the creditor is liable for the balance of the costs.
