The bill amends the Probate Code of 1939 to enhance the court's authority and jurisdiction over juveniles under 18 years of age. It clarifies that the court has exclusive original jurisdiction over juveniles within the county who have violated municipal ordinances or laws, as well as those who are neglected or abandoned. The bill specifies conditions for exercising jurisdiction, such as repeated disobedience to lawful commands or desertion from home without sufficient cause. Additionally, it introduces new definitions for terms like "agency," "case service plan," and "guardian ad litem," which are crucial for understanding the roles of various parties in juvenile proceedings. The bill also removes outdated language and refines definitions to promote clarity and inclusivity, such as replacing gender-specific pronouns with gender-neutral terms.

Moreover, the bill clarifies roles and definitions related to child welfare and juvenile justice, specifying that certain provisions apply to lawyer-guardians ad litem appointed under various laws. It introduces definitions for terms like "nonparent adult," "permanent foster family agreement," and modifies age references for children in foster care agreements. The bill outlines conditions for court petitions regarding juveniles, criteria for removing children from homes, and requirements for maintaining sibling relationships in foster care. It also establishes procedures for DNA testing and assessments for individuals arrested or convicted of specific offenses, including a $60 assessment for certain crimes. Overall, the amendments aim to enhance child protection and streamline legal processes related to their care and custody.
