Modifies and establishes provisions relating to the protection of children

HB 1888 replaces four existing Missouri statutes with 37 new sections that define key terms used in child custody cases. It establishes clear definitions for terms like "child" (under 18), "custody," "home state" (where a child lived for six consecutive months), and "person acting as a parent" to standardize legal proceedings. The bill directly affects courts, legal professionals, and families involved in custody disputes by clarifying the language used in child custody determinations. It does not change substantive custody rules but updates the legal framework for how these cases are processed. This is a procedural clarification bill focused on terminology, not new policy.
