What is judgment is stayed for 30 days?

A judge might decree, "The property shall be sold at auction by the sheriff from the court house steps." Then the judge might announce, "Judgement is stayed for 30 days." That means the property would not be sold immediately but it would be sold in 30 days.

If in that time the person who lost that case appealed to the court of appeals and that court accepted the appeal, then the stay would become longer. The property would not be sold while the appeals court listened to the case.
