Rule 22 Interpleader

(a) Grounds. —

(1) By a Plaintiff. — Persons with claims that may expose a plaintiff to double or multiple liability may be joined as defendants and required to interplead. Joinder for interpleader is proper even though:

(A) the claims of the several claimants, or the titles on which their claims depend, lack a common origin or are adverse and independent rather than identical; or

(B) the plaintiff denies liability in whole or in part to any or all of the claimants.

(2) By a Defendant. — A defendant exposed to similar liability may seek interpleader through a crossclaim or counterclaim.

(b) Relation to Other Rules. — This rule supplements — and does not limit — the joinder of parties allowed by Rule 20.
