Fiduciary duty which is usually based on trust and confidence means to act in the best interest of your client. It is not based on your personal interest and should not result in any pressure being applied to the client. Good faith and fidelity is required in all transactions as it relates to property or money. For example, if you were to receive an advantage in a transaction with your client,
. say profit on an investment, at the expense of your client, then the transaction would be void under the law. That is, if it can be proven that the fiduciary had undue influence over the client. While financial planners have a fiduciary relationship with their clients, the same is not true for a salesperson. The latter can use his or her own personal motives to try and get a sale.
