S.C. Code Ann. § 15-39-730

In judicial sales other than foreclosures or in execution the bidding shall not remain open but shall be closed upon the date of sale unless there be objection at or prior to the hearing at which the decree is rendered to such closing by one or more parties to the suit, in which case the question shall be within the discretion of the court. In sales which involve both partition and foreclosure the bidding shall remain open as in foreclosure sales unless the right to a deficiency judgment is expressly waived.
