How must clients give consent for a lawyer representing another client causing a consentable conflict?

The correct response emphasizes the necessity for "informed consent in writing from every affected client," which is a foundational principle in legal ethics, particularly when managing conflicts of interest. In situations where a lawyer represents multiple clients, and where there is a consentable conflict, it is crucial that the affected clients are fully aware of the implications of this representation. Informed consent means that clients must understand the material risks and potential consequences associated with the conflict of interest.

Written consent is vital because it provides a clear and documented agreement that acknowledges the clients' understanding and acceptance of the risks involved. This written record protects both the clients and the attorney; it ensures that clients have made an informed decision and helps to prevent misunderstandings or disputes about consent in the future.

While verbal consent can sometimes be acceptable in less formal situations, the contexts of legal practice and the complexities involved in conflicts of interest necessitate a higher standard of clarity and documentation. Similarly, while implied consent through conduct might indicate some level of acceptance, it lacks the explicit acknowledgment needed to demonstrate that all affected parties truly understand the ramifications of such a representation. A general agreement could also be too vague and fail to address individual clients' specific concerns and rights. Therefore, written informed consent is the most appropriate and ethical
