Rule 22.
Rule 22. Interpleader
Persons having claims against the plaintiff may be joined as defendants and required to interplead, in an action brought for that purpose, when their claims are such that the plaintiff is or may be exposed to multiple liability. A defendant exposed to similar liability may obtain such interpleader by way of cross-claim or counterclaim. If such a defendant admits being subject to liability, that defendant may, upon paying the amount claimed or delivering the property claimed or its value into court or to such person as the court may direct, move for an order to substitute the claimants other than the plaintiff as defendants in the movant’s stead. On compliance with the terms of such order, the defendant shall be discharged and the action shall proceed against the substituted defendants. It is not ground for objection to such joinder or to such motion that the claims of the several claimants or the titles on which their claims depend do not have a common origin or are not identical with but are adverse to and independent of one another, or that the plaintiff denies liability in whole or in part to any or all of the claimants. The provisions of this rule do not restrict the joinder of parties permitted in Rule 20.
