Attorney-Client Privilege ensures that anything you tell your lawyer in relation to your case cannot be shared with any outside party without your expressed permission. This even includes sharing information with the court, although revealing certain information will likely be required in order to proceed with a personal injury lawsuit.
In order for a conversation to fall under Attorney-Client Privilege, it must be held in private. If any third parties overhear the discussion, it may no longer be considered legally private.
If the conversation reveals intent to commit crimes in the future, Attorney-Client Privilege may not apply.
The confidentiality of Attorney-Client Privilege applies even after representation terminates.
