O.C.G.A. § 13-4-24: Requirements for and effect of tender generally.

A tender properly made may be equivalent to performance. The tender must be certain and unconditional, except for a receipt in full or delivery of the obligation, and may be made by an agent and to an agent authorized to receive. The tender must be in full payment of the specific debt, and not in part, and may be made at any time before trial. If tender is rejected on grounds unrelated to informality, informality cannot afterward be raised in objection to the tender.
