The court may, for good cause, stay the proceedings on any 1 or more of such executions, direct under which execution a sale shall be first made or order the proceeds of any sale to be paid into court.
If a sale shall be made contrary to the provisions of this section, the party at whose instance the executions have issued and his attorney shall be liable as trespassers to the adverse party for all damages he may sustain thereby.
