Modifies provisions relating to termination of parental rights proceedings

HB 573 modifies Missouri's process for termination of parental rights cases by extending the timeline for serving legal notices from 30 to 60 days, with courts allowed to extend further if it serves the child's best interests. It requires courts to order a social study (including parental fitness, child's condition, and home environment) within 60 days, with the written report shared with all parties 15 days before the hearing. The bill also mandates a dispositional hearing within 30 days of the initial meeting, grants subpoena power to participants, and provides immunity to agencies following child welfare protocols. This directly affects parents, children in custody cases, judges, and child welfare agencies by changing procedural deadlines and transparency requirements.
