Rule 52.07.Interpleader.

Rule 52.07 addresses a stakeholder's problem: what happens when several people each claim a right to the same fund or property, and paying one might leave the plaintiff exposed to a later claim from another? Interpleader answers this by joining the rival claimants as defendants and requiring them to interplead — that is, to litigate their competing claims against one another in a single case — whenever their claims expose the plaintiff to double or multiple liability.

The rule is notably permissive about how similar the competing claims need to be. It is not a valid objection to the joinder that the claimants' claims, or the titles their claims depend on, lack a common origin, or that they are adverse to and independent of one another, or that the plaintiff admits no liability at all, in whole or in part, to any or all of the claimants. This lets a genuine stakeholder use interpleader even when the rival claims arose from entirely separate events.

A defendant facing similar exposure can obtain the same relief by way of a cross-claim or counterclaim instead of starting a new action. And Rule 52.07 does not narrow the general joinder rule in Rule 52.05 — it supplements that rule, adding another route to bring competing claimants into one case instead of displacing the ordinary joinder standard.
