HB 3909 updates Oklahoma divorce and custody laws to better protect children. It requires courts to appoint child advocates (guardians ad litem) who must follow a new standard operating manual on child welfare, domestic violence, and best practices. The bill mandates full disclosure of qualifications, disciplinary history, and criminal records for all court-appointed experts (including advocates), and prohibits parties from waiving these disclosure requirements. These changes directly affect parents, judges, and professionals handling child custody cases in Oklahoma.
