Attorney-Client Privilege is a legal principle that protects the confidentiality of communications between a client and their attorney. This privilege ensures that anything discussed in private cannot be disclosed in court without the client's consent, encouraging open and honest communication. The privilege applies to both verbal and written communications, as long as they are made for the purpose of seeking legal advice. However, there are exceptions, such as when the communication involves ongoing or future criminal activity. Overall, Attorney-Client Privilege is essential for maintaining trust in the legal process.
