246 Pa. Code Rule 419
The officer executing the order shall make a return on the order of execution form. The return shall show:
(7) If no levy upon property of the defendant could be made, or if the levy was abandoned, the reasons therefor; or that the order was returned unexecuted for nonpayment of expenses and fees.
Official Note
Compare Pa. R.C.P. No. 3139. The return required by this rule is quite detailed in view of the fact that executing officers will often be constables.
