Georgia Code Title 9. Civil Practice § 9-11-22

(a) Persons having claims against the plaintiff may be joined as defendants and required to interplead when their claims are such that the plaintiff is or may be exposed to double or multiple liability. It is not ground for objection to the joinder that the claims of the several claimants or the titles on which their claims depend do not have a common origin or are not identical but are adverse to and independent of one another or that the plaintiff avers that he is not liable in whole or in part to any or all of the claimants. A defendant exposed to similar liability may obtain such interpleader by way of cross-claim or counterclaim. This Code section supplements and does not in any way limit the joinder of parties permitted in Code Section 9-11-20.

(b) The remedy provided in this Code section is in addition to and in no way supersedes or limits the remedy of equitable interpleader provided for in Code Sections 23-3-90 through 23-3-92.
