In the law of criminal evidence, a confession is a statement by a suspect in crime which is adverse to that person. Some secondary authorities, such as Black's Law Dictionary, define a confession in more narrow terms, for example. as "a statement admitting or acknowledging all facts necessary for conviction of a crime," which would be distinct from a mere admission of certain facts that, if true, would still not, by themselves, satisfy all the elements of the offense. The equivalent in civil cases is a statement against interest.
