A more thorough explanation:

The etiquette of the profession refers to the minimum standards of appropriate conduct within the legal profession. This involves the duties that lawyers owe to one another, their clients, and the courts. It is also known as legal ethics.

Legal ethics can be understood in two ways. Firstly, it refers to the system of professional regulations that govern the conduct of lawyers. Secondly, it is a special case of ethics in general, as ethics is understood in the central traditions of philosophy and religion. From this broader perspective, legal ethics concerns the fundamentals of our moral lives as lawyers.

For example, a lawyer has a duty to keep their client's information confidential. This means that they cannot share any information about their client's case with anyone else without their client's permission. Another example is that a lawyer must be honest with their clients and the court. They cannot lie or misrepresent facts in order to win a case.

These examples illustrate the importance of the etiquette of the profession. Lawyers must uphold these standards in order to maintain the trust of their clients and the integrity of the legal system.
