GARNISHMENT. A warning to any one for his appearance, in a cause in which he is not a party, for the information of the court, and explaining a cause. For example, in the practice of Pennsylvania, when an attachment issues against a debtor, in order to secure to the plaintiff a claim due by a, third person to such debtor, notice is given to such third person, which notice is a garnishment, and he is called the garnishee.
2. In detinue, the defendant cannot have a sci. fac. to garnish a third person unless he confess the possession of the chattel or thing demanded. Bro. Abr. Garnishment, 1, 5. And when the garnishee comes in, he cannot vary or depart from the allegation of the defendant in his prayer of garnishment. The plaintiff does not declare de novo against the garnishee; but the garnishee, if he appears in due time, may have oyer of the original declaration to which he pleads. See Bro. Abr. Garnishee and Garnishment, pl. 8, and this title, passim.
