The Legislature has established by statute in which cases and in what amounts minimum bids may be required for execution sales. The Sheriff, as a ministerial officer, lacks both the duty and authority to unilaterally require a minimum bid in any specific amount and must accept a bid even though such bid appears merely nominal. Consequently, unless otherwise ordered by the court, the minimum bid may only be required at an execution sale if: (1) there is a statutory minimum bid, or (2) the judgment creditor has given sale instructions including a minimum bid, in which event the bid must meet or exceed any statutory minimum bid.
