conflict of interest
n. a situation in which a person has a duty to more than one person or organization, but cannot do justice to the actual or potentially adverse interests of both parties. This includes when an individual's personal interests or concerns are inconsistent with the best for a customer, or when a public official's personal interests are contrary to his/her loyalty to public business. An attorney, an accountant, a business adviser or realtor cannot represent two parties in a dispute and must avoid even the appearance of conflict. He/she may not join with a client in business without making full disclosure of his/her potential conflicts, he/she must avoid commingling funds with the client, and never, never take a position adverse to the customer.
