Aberrant Auction Law, Kentucky #10
a sale by auction is complete when the auctioneer so announces by the fall of the hammer, announcing the item sold, and the successful bidder’s identification or in other customary manner. If it becomes immediately apparent at the close of the bidding that the auctioneer and a bid assistant or ringman have acknowledged the same bid from different bidders, the auctioneer may continue the bidding between the disputed bidders. When a bid is made while the auctioneer is in the process of completing the sale by auction, the auctioneer may continue the bidding or declare the real or personal property sold under the bid on which the hammer was falling.
