I want a therapist that will testify and get the truth out... .not just a therapist for my son to see someone.
My son's therapist had us sign a waiver that she would not testify. I was worried about that, but in the end, it was the best thing. It means your T is committed to helping your son. He needs someone like that right now, a place where he has true confidentiality.
Your son's therapist is probably not a forensic psychologist -- that's why there are GALs and Custody Evaluators. So let the forensic psychologists do what they do, and let your son's T do what she does. It will be ok. It's best for your son.
