In aid of the judgment or of its execution, the judgment creditor or his successor in interest may examine any person including the judgment debtor, as is provided in these rules for the taking of depositions. If the deposition is taken by written questions, the subpoena for the taking thereof may provide that the judgment debtor or deponent need not appear personally thereunder, provided that before the time fixed for the taking of the deposition he delivers to the judgment creditor or to his attorney answers under oath to the written questions served upon him. The court may make any order which it considers just and necessary for the execution of a judgment.
