Which rule primarily governs conflicts of interest with current clients in the context of multiple clients in a single matter?

• A. Model Rule 1.7 (conflicts of interest with current clients)
• B. Model Rule 1.3 (diligence)
• C. Model Rule 5.3 (supervision)
• D. Model Rule 4.2 (communication with representing clients)

Answer: (A)

Conflicts of interest between current clients in the same matter are governed by Model Rule 1.7. This rule says a lawyer generally cannot represent two or more clients in the same matter if there is a significant risk that the representation will be materially limited by duties to another client, a former client, or the lawyer’s own interests, unless each affected client gives informed consent, confirmed in writing. This framework allows handling concurrent conflicts through proper disclosure and consent, or requiring limitation or declining representation if consent cannot be obtained. The other rules address different topics—1.3 focuses on diligence and continuity of representation, 5.3 on supervising non-attorney staff, and 4.2 on communications with represented persons—so they don’t govern the multi-client conflict scenario as directly as 1.7.
