An admission against interest is an exception to the hearsay rule which allows a person to testify to a stament of another that reveals something incriminating, embarassing, or otherwise damaging to the maker of the statement. It is allowed into evidence on the theory that the lack of incentive to make a damaging statement is an indication of the statement's reliability.
In criminal law, it is a statement by the defendant which acknowledges the existence or truth of some fact necessary to be proven to establish the guilt of the defendant or which tends to show guilt of the defendant or is evidence of some material fact, but not amounting to a confession.
