Under what condition can private investigators share their findings with third parties?

Private investigators are bound by ethical and legal standards, which emphasize the importance of client confidentiality. The correct option highlights that private investigators can share their findings with third parties only when they have obtained consent from their client. This principle is rooted in the obligation to protect sensitive information and maintain the trust that clients place in investigators.

Sharing information without consent could lead to legal repercussions, disciplinary actions, and a breakdown of the professional relationship between the investigator and the client. This ensures not only the privacy of the client’s information but also protects the integrity of the investigative process.

The other conditions mentioned, such as acting in the public interest or using findings for marketing, may be tempting but do not align with the ethical standards expected in the profession. Thus, consent remains a fundamental requirement before sharing findings with any third parties.
