A garnishee summons lapses and the garnishee is discharged of any liability upon the expiration of three hundred sixty days after the service of the summons, or a longer period of time either agreed to in writing by the plaintiff and the defendant or ordered by the court. Immediately upon the lapse of the garnishee summons, all earnings, money, property, and effects that the garnishee has been retaining pursuant to the garnishment must be returned to the defendant if the defendant is otherwise legally entitled to receipt of them.
