This bill introduces a new section to chapter 26.09 RCW, focusing on child custody decisions with an emphasis on the health and safety of children, particularly in cases involving domestic violence or child abuse. It mandates that professionals providing recommendations to the court must have substantial training and experience in these areas. The bill specifies that a postgraduate degree alone does not qualify someone as an expert in domestic violence, and courts are instructed to rely on current scientific research when making custody decisions. It also outlines the conditions under which custody and visitation should be awarded, emphasizing that the safe parent should receive sole custody unless there is clear evidence of imminent risk from the other parent.

Additionally, the bill requires courts to conduct evidentiary hearings in cases with allegations of domestic violence and prohibits the use of outdated practices that do not align with scientific evidence. Judges and guardians ad litem are mandated to receive specialized training on these new practices, and domestic violence advocates are encouraged to provide training to court personnel. The legislation aims to correct ineffective practices in custody cases and ensure that decisions are made based on valid research and expert knowledge, ultimately prioritizing the safety and well-being of children involved in custody disputes.
