O.C.G.A. § 10-1-627

No franchisor, nor any agent nor employee of a franchisor, shall use a written instrument, agreement, or waiver to attempt to nullify any of the provisions of this article and any such agreement, written instrument, or waiver shall be null and void. This Code section shall not prevent a dealer from voluntarily entering into a valid release agreement to resolve a specific claim, dispute, or action between the franchisor and the dealer or when separate and adequate consideration is offered and accepted, provided that the renewal of a franchise shall not by itself constitute separate and adequate consideration.
