O.C.G.A. § 23-2-71: Entitlement to contribution; when equity has jurisdiction.

In cases of joint, joint and several, or several liabilities of two or more persons, where all are equally bound to bear the common burden and one has paid more than his share, he shall be entitled to contribution from the others; and whenever the circumstances are such that an action at law will not give a complete remedy, equity may entertain jurisdiction.
