I have such a case, a female case manager was appointed after I had been put in the home with the kids due to the recommedation of a GAL, the case manager suggested within weeks with no further factual information the mother be put back in the home. She clearly had an agenda, by the way, she kept working at it and accomplished it a couple months later.
I would advocate judges being requried to attend training in the roles of GAL's, case managers, and having a basic understanding of psychological matters concerning kids and divorce. The judges should at least know what is expected.
