Rule 804(b)(3) of the Federal Rules of Evidence
Definition
Provides that a statement that was against the declarant’s pecuniary or proprietary interest at the time he made it is admissible as an exception to the hearsay rule if the declarant is unavailable as a witness. In criminal proceedings, statements that incriminate an out-of-court declarant must be supported by corroborating circumstances that clearly indicate trustworthiness.
