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:
   1. 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
   2. 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 AND STATUTES. This rule supplements — and does not limit — the joinder of parties allowed by Rule 20. The remedy this rule provides is in addition to — and does not supersede or limit — the remedy provided by 28 U.S.C. §§1335, 1397, and 2361. An action under those statutes must be conducted under these rules.
