Which action must an investigator take when they no longer represent a client?

When an investigator concludes their representation of a client, it is essential to formally notify the client in writing. This action serves multiple purposes. First, it creates a clear record of the termination of the professional relationship, ensuring that both the investigator and the client have documented communication regarding the end of their engagement. This written notification helps prevent any misunderstandings or assumptions about continuing obligations or the scope of work to be completed.

Additionally, written communication provides a tangible reference for both parties, which can be important in case any disputes arise in the future. It allows the investigator to outline the reasons for termination and clarify any ongoing obligations that may need to be addressed, such as the return of documents or final reporting. In contrast, ceasing investigations immediately or continuing to assist the client without formal notification does not provide the necessary clarity or professionalism associated with ending such a relationship. While donating earnings or continuing to assist the client may seem generous, they do not align with the ethical and procedural standards expected in professional investigator conduct.
