Which term refers to the barrier used within a firm to separate matters to prevent conflicts of interest?

• A. Ethical wall or screen or cone of silence
• B. Vicarious representation
• C. Confidentiality
• D. Unauthorized practice of law

Answer: (A)

An ethical wall, sometimes called a screen or cone of silence, is the barrier inside a firm that separates matters to prevent conflicts of interest from arising. It keeps the teams working on different matters from sharing information, documents, or even discussing a case, so one matter cannot influence another. This is crucial when the firm handles multiple clients with potentially conflicting interests or when sensitive information needs to be kept from leaking between matters. It’s different from confidentiality, which protects client information from outsiders and isn’t about structuring internal groups. It also isn’t about vicarious representation (acting through another) or about the unauthorized practice of law, which concerns who is legally allowed to perform legal services.
