Beginning on or before July 1, 2028, the act extends certain application, accounting, and notice provisions already in place for federal survivor benefits awarded to a child or youth who is in foster care (child or youth) to federal supplemental security income benefits (SSI), which are monthly payments awarded to a child or youth with a disability and limited resources. The act adds requirements for a county department of human or social services (county department) to follow specified procedures for identifying a child or youth with a disability who may qualify for SSI and for documenting the disability. If the county department determines that a child or youth may be eligible to receive SSI, the county department is required to initiate the application process within 45 days after receiving certain information. If a child or youth is receiving SSI, the county department must document how the money is spent in the state's child welfare case management system. If legal custody of a child or youth receiving SSI or federal survivor benefits is transferring from a county department to another individual, the act requires the county department to reassess the designation of the representative payee or fiduciary receiving and managing federal benefits on behalf of the child or youth. The reassessment must be performed in consultation with interested parties and in compliance with federal requirements.(Note: This summary applies to this bill as enacted.)
