In 2023, Sam achieved a unanimous 8-0 victory in the Texas Supreme Court for his pro bono client, securing the right for the client's eldest daughter to be interviewed in a custody determination, as required by Texas law. Texas family law courts were routinely ignoring the interview requirement in contravention of Texas law and the best interests of children caught in custody litigation. The landmark decision ensures that interview rights for children in similar situations will be protected in the future. Sam took the case on appeal to the intermediate court of appeals, and successfully petitioned the Texas Supreme Court to review and reverse the intermediate court decision.
