Does the Juvenile Court or the adoption agency have to inform prospective adoptive parents of every potentially troubling issue in the biological parents' family history?

As mother admits, no authority supports her assertion that the juvenile court or the agency must inform prospective adoptive parents, prior to the section 366.26 hearing, of every potentially troubling issue in the biological parents' family histories. We reject this premise on that ground. (Kim v. Sumitomo Bank (1993) 17 Cal.App.4th 974, 979.) In any event, prospective adoptive parents are likely to realize that minors in the juvenile dependency system are available for adoption only because their biological parents' problems were grave enough to disable them as parents. Mother's speculation that the parents' mental health or substance abuse problems might be inheritable is utterly without foundation.
