Legally, anyone who represents someone else (attorneys, realtors, accountants, employees, artist agents and artist managers, etc.) are all considered “agents”. The people they work for are called “principals.” The Law of Agency governs the relationship between agents and principals. While the Law of Agency imposes duties on both agents and principals, for purposes of this discussion, there are four key concepts:
(1) An agent works for the principal and, while the agent can advise the principal, the agent must follow the instructions and directives of the principal.
(2) An agent can never put his or her own interests above that of the principal.
(3) All of the “results and proceeds” of the agent’s work on behalf of the principal belongs to the principal.
(4) Any contractual provision, written or oral, that contravenes rules (1) – (3) is null and void.
In short, when a manager represents an artist, the manager has no proprietary information. In other words, those aren’t your leads and contacts, they are the artist’s. While your leads and contacts may start out as your own, once you contact someone on behalf of an artist, the artist is legally entitled to know anyone you have spoken to on his or her behalf, including the details of such conversation.
