Generally revise child custody laws

This bill revises Montana's child custody laws to prioritize child safety and requires judges, standing masters, and guardians ad litem to complete mandatory training on domestic violence and child abuse. The legislation establishes specific training requirements, including an initial 20-hour orientation course and 15 hours of ongoing training every two years, focusing on topics like child sexual abuse, coercive control, and trauma-informed care. Courts will be better equipped to recognize and adjudicate abuse allegations based on admissible evidence, and professionals involved in custody cases must receive training from evidence-based sources that may include survivors of abuse. The bill also updates legal definitions to clarify what constitutes a child custody proceeding and ensures the training addresses implicit bias and culturally appropriate responses for diverse communities.
