When the person, firm, corporation, association or other entity against whom such claims are made, or may be made, is a defendant in an action brought upon one or more of such claims, it may either file a verified cross-complaint in interpleader, admitting that it has no interest in the money or property claimed, or in only a portion thereof, and alleging that all or such portion is demanded by parties to such action, and apply to the court upon notice to such parties for an order to deliver such money or property or such portion thereof to such person as the court shall direct; or may bring a separate action against the claimants to compel them to interplead and litigate their several claims. The action of interpleader may be maintained although the claims have not a common origin, are not identical but are adverse to and independent of one another, or the claims are unliquidated and no liability on the part of the party bringing the action or filing the cross-complaint has arisen. The applicant or interpleading party may deny liability in whole or in part to any or all of the claimants. The applicant or interpleading party may join as a defendant in such action any other party against whom claims are made by one or more of the claimants or such other party may interplead by cross-complaint; provided, however, that such claims arise out of the same transaction or occurrence.
