No trustee summons may be served unless attachment on trustee process for a specified amount has been approved by order of the court. Except as provided in subdivision (g) of this rule, the order of approval may be entered only after notice to the defendant and hearing and upon a finding by the court that there is a reasonable likelihood that the plaintiff will recover judgment, including interest and costs, in an amount equal to or greater than the amount of the trustee process over and above any liability insurance shown by the defendant to be available to satisfy the judgment.
An action in which trustee process is sought may be commenced only by filing the complaint with the court, together with a motion for approval of attachment on trustee process. The motion shall be supported by affidavit or affidavits meeting the requirements set forth in Rule 4.1(h). Except as provided in subdivision (g) of this rule, the motion and affidavit or affidavits with the notice of hearing thereon shall be served upon the defendant in the manner provided by Rule 4, at the same time the summons and complaint are served upon him; and the defendant shall also be served with a copy of the trustee summons in cases where attachment has been approved ex parte as provided in subdivision (g) of this rule. Inclusion of a copy of the complaint in the notice of hearing shall not constitute personal service of the complaint upon the defendant. The notice shall inform the defendant that by appearing to be heard on the motion for approval of an attachment on trustee process he will not thereby submit himself to the jurisdiction of the court nor waive service of the complaint and summons upon him in the manner provided by law.
Except as provided in subdivision (f) of this rule, any trustee process shall be served within 30 days after the date of the order approving the attachment. Promptly after the service of the trustee summons upon the trustee or trustees, a copy of the trustee summons with the officer's endorsement thereon of the date or dates of services shall be served upon the defendant in the manner provided by Rule 5.
