Del. Code tit. 10, § 5031

The plaintiff in any judgment in a court of record, or any person for such plaintiff lawfully authorized, may cause an attachment, as well as any other execution, to be issued thereon, containing an order for the summoning of garnishees, to be proceeded upon and returned as in cases of foreign attachment. The attachment, condemnation, or judgment thereon, shall be pleadable in bar by the garnishee in any action against the garnishee at the suit of the defendant in the attachment. Goods which are perishable, or will create a charge by keeping, may be sold on the order of a judge as in cases of foreign attachment.
