Malpractice refers to a failure by a professional, typically in the fields of law or medicine, to perform their duties with the necessary competence and care, resulting in harm to a client or patient. This term is closely linked to issues of negligence, as it often involves the breach of a duty that leads to injury or damage. Malpractice also touches on concepts of confidentiality, competence, diligence, and the expectation of candor and integrity within professional relationships.
