Rule text
(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.
