If the attachment be against a principal defendant who is a nonresident or an absconding debtor, the attachment may also direct the sheriff or other officer to levy the same on any remainder, vested or contingent, of the principal defendant, or so much thereof as may be sufficient to pay the amount for which it issues. But no such remainder shall be sold until it becomes vested. A judgment, however, ascertaining the amount due the plaintiff may be docketed as other judgments are docketed, but unless it be a personal judgment, it shall be a lien only on the property levied on.
