Client confidentiality refers to the ethical and legal obligation of professionals, such as lawyers, doctors, and therapists, to protect the privacy of their clients. This means that any information shared during consultations or sessions cannot be disclosed to others without the client's consent. This principle helps build trust between clients and professionals, encouraging open communication. Maintaining client confidentiality is crucial in various fields, as it safeguards sensitive information and promotes a safe environment for clients to express their concerns. Breaches of confidentiality can lead to legal consequences and damage the professional's reputation, making it essential to adhere to these standards.
