Ala. Code § 6-6-410

A debt or demand which is subject to garnishment may be reached and subjected though an action may be pending thereon; and if the action is not pending in the court from which the garnishment issues, the court, on proof by the garnishee of the pendency of the garnishment, must, on the entry of judgment, stay execution until notified by the clerk of the court in which the garnishment or attachment is instituted that final judgment has been entered, in which case he must make the appropriate order according to whether the judgment is entered for the plaintiff or defendant.
