Requires the supervising agency to provide the child's foster parents, preadoptive parents, or relative caregivers with notice of their right to be heard prior to each proceeding held with respect to the child in juvenile court under chapter 13.34 RCW. The rights to notice and to be heard apply only to persons with whom a child has been placed by the supervising agency and who are providing care to the child at the time of the proceeding. This act shall not be construed to grant party status to any person solely on the basis of such notice and right to be heard.

Provides that any foster parent who receives information about a child or a child's family pursuant to this act shall keep the information confidential and shall not further disclose or disseminate the information, except as authorized by law. Such individuals shall agree in writing to keep the information that they receive confidential and shall affirm that the information will not be further disclosed or disseminated, except as authorized by law.
