The whole treatment is for the benefit of the client.

If the notes can be shared with insurance, used for court, or shared with anyone for other purposes, you have a right to know what a therapist is writing about you.

Especially notes your insurance company may get-that can cause problems the rest of your life, so those are notes you may want to see to ensure accuracy or to be informed in general. Do you think the insurance company actually protects the confidentially of such notes as you would? Think again. No, the only one protecting you is you.

Personal notes that would never be shared outside of the T are not my concern. A decent T would not send such notes to an insurance company anyway (they would have a seperate set) or anyone else as they know the potential implications. But some Ts are not as smart as others and may do something that stupid.
