SOCIAL WORK CONFIDENTIALITY LAW

It's for Connecticut but I'm sure it's the same, or close to the same, everywhere else. It seems to be in your favor

excerpt:

What Communications and Records are Covered? All oral and written communications and records thereof relating to the evaluation and treatment of the client(s). This applies to communications between the client and the social worker, between a member of the clientâ??s family and the social worker, and between the client or a member of the clientâ??s family and an individual participating under the supervision of a licensed clinical social worker in the accomplishment of the objectives of evaluation or treatment. The confidentiality applies wherever the communications took place.
