A person who is or may be exposed to multiple liability or vexatious litigation because of several claims against the person for the same thing, may bring an equitable action of interpleader against all such claimants. Their claims or titles need not have a common origin, nor be identical, and may be adverse to, or independent of each other. Such person may dispute liability, wholly or in part.
