he attorney-client privilege is designed to protect the confidentiality of communications between a lawyer and their client. However, there are exceptions to this rule. According to the American Bar Association's Model Rules of Professional Conduct, Rule 1.6, an attorney may reveal information relating to the representation of a client to prevent reasonably certain death or substantial bodily harm. This means that if an attorney learns from a third party that their client is planning to harm someone, they may have a duty to disclose this information. If the attorney discloses this information under these circumstances, they would generally not be sanctioned, as the disclosure is made in accordance with the rules of professional conduct. However, the specifics can vary by jurisdiction, so it's always important to consult the relevant local rules and regulations. Sources
