declaration against interest — Definition and meaning
In order for a statement to meet this exception, it must meet a few requirements under the Federal Rules of Evidence. First, the declarant must be unavailable as a witness. Second, the party offering the statements must prove that the statements would harm the declarant’s legal claims against someone or aid in legal claims against themselves. For example, if a declarant said they had multiple drinks before crashing into another vehicle, that statement would be against the interests of the declarant in a driving under the influence case. Lastly, in a criminal case, there must be other circumstantial evidence that makes the statements more trustworthy. These requirements vary between states and the federal rules of evidence, but they generally all have similar requirements to the Federal Rules. Also, a declaration against interest potentially will not be admissible if circumstances call into question the trustworthiness of the statement. For example, a declaration against interest may be inadmissible if the declarant was being forced into making the statement.
