Which term refers to the requirement for a lawyer to be truthful in their dealings?

The term that refers to the requirement for a lawyer to be truthful in their dealings is "honesty and candour." This concept is fundamental to the legal profession, as lawyers are expected to act not only with honesty but also with a commitment to being open and forthright in their communications.

Honesty involves being truthful in all representations, while candour emphasizes the need to inform and disclose relevant information to clients, courts, and others with whom they are engaged. This requirement is critical as it fosters trust and upholds the integrity of the legal system. A lawyer's duty of honesty and candour is not just about avoiding deceit; it also involves actively ensuring that all parties have a clear understanding of relevant facts and legal positions as part of their professional conduct.

The other terms, such as transparency, integrity, and truthfulness, though related, do not capture the comprehensive ethical expectation that lawyers must embody in their communications and interactions. Transparency often relates to the clarity of processes and information, integrity encompasses broader principles of moral uprightness, and truthfulness speaks to the act of being true, but does not encapsulate the broader duty of disclosure and openness required in legal practice.
