O.C.G.A. § 44-11-3: Right of joint owner to bring an action alone; effect of judgment.

Any joint tenant, tenant in common, or other person having a part interest in lands or tenements may bring an action of ejectment for the recovery of such lands or tenements or an action for damages for injury thereto without joining with him any other person as plaintiff. The judgment in such a case shall not affect the rights of those interested in such lands or tenements who are not parties to the action.
