If, upon demand so made, the garnishee neglects or refuses to make such payment or delivery, the plaintiff in the foreign attachment may maintain a scire facias against him as executor, administrator or trustee, as aforesaid. If the plaintiff recovers judgment, no execution shall be issued, but the defendant may pay upon the same the whole, or so much of the moneys or of the value of the effects attached, and for which he would otherwise have been liable to the original defendant, as may be necessary to satisfy the judgment; which payment shall be credited to such executor, administrator or trustee in his administration account; but he shall not be credited with the costs recovered on such scire facias, unless the Court of Probate is of the opinion that he was justified in incurring the same. If he does not so pay such judgment, so much of the same, including interest thereon from the date when such judgment was rendered, as does not exceed the whole of the moneys or of the value of the effects attached, and for which he would otherwise have been liable to the original defendant, and no more, may be recovered by the attaching creditor in an action on the probate bond, and not otherwise.
