At any time before a judgment is satisfied or vacated, the judgment creditor may compel disclosure of all matter relevant to the satisfaction of the judgment, by serving upon any person a subpoena, which shall specify all of the parties to the action, the date of the judgment, the court in which it was entered, the amount of the judgment and the amount then due thereon, and shall state that false swearing or failure to comply with the subpoena is punishable as a contempt of court.
