HB 507 amends Article 26.052 of the Texas Code of Criminal Procedure to establish a statewide capital defense training and standards committee. This committee will create policies and standards for providing legal representation to indigent defendants in death penalty cases, including attorney qualifications, training requirements, and continuing education. The bill also requires local selection committees to post qualified attorney lists online and review these lists annually. The changes apply to capital felony cases filed on or after September 1, 2025.
