• Judicial privilege: protects statements made in the course of a judicial proceeding by judges, jurors, parties, witnesses, or advocates.
• Attorney-client privilege: allows a client to refuse to disclose and prevent others from disclosing confidential communications between the client and their attorney.
• Doctor-patient privilege: gives patients the right to exclude from discovery and evidence in a legal proceeding any confidential communication made to a physician for diagnosis or treatment.
