I think if the client sees a benefit to the new T seeing the old records, then he/she should go ahead with the transfer. I personally would not do it, as I prefer to communicate with my T myself. He can find out everything he needs to know from me. When I started with my T, I did tell him I had a previous therapist, and he never showed any interest in getting me to request my file be sent to him. I guess he had faith in his own abilities and didn't need to see the conclusions of someone else. I also think it might have biased him. My diagnosis with the first T was probably depression. With my current T, it is PTSD. I think it's good to let them explore and uncover on their own. They are going to find out different things from the client based on their skills and approach and what the client shares with them. What the client shares can vary tremendously from T to T.
