My wife and I are seeing a marriage therapist to discuss strategies for dealing with our conditions when they affect the relationship. I have ADHD and she has MDD
We both have individual therapists and psychiatrists.

I would like to know what level of cordination is usual beween all the professionals involved. Is it normal for a marriage therapist to want to consult with a psychiatrist?
I am very confused why our Marriage therapist sees it prudent to request authorization to talk with my psychiatrist about my diagnosis and medication. The Marrage therapist also said that she did not want authorization to talk to my individual therapist. I would think it more normal for her to talk with my therapist rather then psychiatrist.
