Attorney's Duty of Confidentiality
Definition - What does Attorney's Duty of Confidentiality mean?
An attorney's duty of confidentiality is a legal requirement an attorney has to their client not to disclose anything the client says to them without express permission from the client to do so. The attorney is not allowed to speak to anyone except the client and the people that the client deems acceptable; this may or may not include the prosecution or the judge. The duty of confidentiality continues after the case is heard and is thought of as lasting forever unless the privilege is waived.
Justipedia explains Attorney's Duty of Confidentiality
There are special occasions when a judge can force an attorney to give information held in confidence, but they are rare and usually the result of trying to stop a heinous crime from occurring such as if a victim is nearing death and the defendant can help to save the life of the person by sharing information that helped the police.
