There are different types of note taking done by mental health practitioners.

Notes placed in the "official" medical record are property of the clinic or hospital, but patients have a right to access these records.

"Other" notes filed in other types of patient files or records are not accessible to the patient. These are purposely withheld from patients' "official" record for legal reasons (I think). There may be time limits for disposal of these types of notes, but I'm not sure. (There should be time limits!)

Not everyone takes notes.
