here in NY and if I remember right here in the USA a client can have copies of ***everything**** that is in their treatment files. including the actual session notes that a treatment provider writes. the law here that give a client that right to have copies of everything with in their medical and psychiatric records is called "right of access"

both my wife and I have complete copies of our medical and mental health records. it wasnt that hard to get them we just asked our treatment providers for them, they sent them on to the new treatment providers and then the new treatment providers photocopied the complete files for us. we have both the formal official forms write ups of when we saw our treatment providers and we have the sporadic word here word there brief type notes that our treatment providers wrote while we were right there with them.

suggestion talk with your treatment providers the Right of access law might be the same where you are.
