Legal malpractice is the term for negligence, Breach of Fiuciary Duty, or Breach of Contract by an attorney that causes harm to his or her client. In order to rise to an actionable level of negligence, the injured party must show that the attorney's acts were not merely the result of poor strategy, but that they were the result of errors that no reasonable attorney would make. Furthermore, legal malpractice requires the showing of an injury that would not have happened had the attorney not been negligent. If the injury might have occurred despite different (non-negligent) actions by the attorney, no cause of action will be permitted. Legal malpractice can also occur when an attorney breaches a fiduciary duty to his or her client. This occurs when attorneys act in their own interest instead of to their client's, to the detriment of their client. A claim for legal malpractice may also arise when an attorney breaches the contract they sign with their client.
