Curtis Leon Thomas had significant intellectual and physical disabilities and lived in medical facilities from adolescence. His mother, Elnora Lynn, signed an arbitration agreement with a care facility on his behalf. After Thomas died, Lynn sued the facility, and the trial court compelled arbitration and confirmed the resulting award. The Georgia Court of Appeals held that Lynn lacked authority to bind Thomas to arbitration because she had not shown legal authority to sign for him. The court rejected the facility’s argument that Thomas was bound as a third-party beneficiary, emphasizing that he had not sought to enforce the agreement and that admission or care was not conditioned on signing it. The court reversed both the order compelling arbitration and the order confirming the award, allowing Lynn’s claims to proceed in ordinary litigation.
