A child placement agency shall make reasonable efforts to compile and make available to a prospective adoptive parent: all of the prospective adoptee’s medical and mental health records that the agency has; or a comprehensive medical and mental health history of the prospective adoptee. On request of a prospective adoptive parent, a child placement agency shall make reasonable efforts to compile a pertinent medical and mental health history of each of the prospective adoptee’s parents, if available to the agency, and to make the history available to the prospective adoptive parent. If, after adoption, a child placement agency receives medical or mental health information about the adoptee or adoptee’s former parent, the agency shall make reasonable efforts to make the information available to the adoptive parent. If, after adoption, the adoptive parent requests additional information, the child placement agency shall make reasonable efforts to notify the former parent, at the former parent’s last known address available to the agency, of the request and the reason for the request. A medical or mental health history compiled under this section may not contain identifying information as to a parent.
