Declaration against interest

Under the Federal Rules of Evidence, a declaration against interest is defined as a statement made by a declarant who is unavailable that is against the declarant’s pecuniary, proprietary, or penal interest when it was made. A statement against interest is admissible as an exception to the [wex:hearsay] rule. However, for a statement against penal interest to be admissible in a criminal case, it must be supported by corroborative evidence.
