Federal Rules of Evidence/Authentication

Article IX of the Federal Rules of Evidence deals with authentication and identification of evidence.

Rule 901. Requirement of Authentication or Identification

 * (a) General provision. The requirement of authentication or identification as a condition precedent to admissibility is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims.

When a piece of physical evidence is presented in the courtroom, other evidence must often be presented to prove that the evidence is what it is claimed to be. Rule 901(b) provides an incomplete list of many ways to do this.


 * (b) Illustrations. By way of illustration only, and not by way of limitation, the following are examples of authentication or identification conforming with the requirements of this rule:


 * (1) Testimony of witness with knowledge. Testimony that a matter is what it is claimed to be.

Such testimony can be very simple. "I'm showing you what has been marked as Exhibit A. Do you recognize it?" "Yes. It's a picture of my cat. I can recognize the spot on her tail." Or it can be very complicated, depending on the nature of the evidence and the attitude of opposing counsel.


 * (2) Nonexpert opinion on handwriting. Nonexpert opinion as to the genuineness of handwriting, based upon familiarity not acquired for purposes of the litigation.
 * (3) Comparison by trier or expert witness. Comparison by the trier of fact or by expert witnesses with specimens which have been authenticated.
 * (4) Distinctive characteristics and the like. Appearance, contents, substance, internal patterns, or other distinctive characteristics, taken in conjunction with circumstances.

Although only Rule 901(b)(2) mentions handwriting specifically, handwriting can also be authenticated by comparison under Rule 901(b)(3), or by expert opinion under Rule 901(b)(4).


 * ''(5) Voice identification. Identification of a voice, whether heard firsthand or through mechanical or electronic transmission or recording, by opinion based upon hearing the voice at any time under circumstances connecting it with the alleged speaker.
 * ''(6) Telephone conversations. Telephone conversations, by evidence that a call was made to the number assigned at the time by the telephone company to a particular person or business, if (A) in the case of a person, circumstances, including self-identification, show the person answering to be the one called, or (B) in the case of a business, the call was made to a place of business and the conversation related to business reasonably transacted over the telephone.
 * ''(7) Public records or reports. Evidence that a writing authorized by law to be recorded or filed and in fact recorded or filed in a public office, or a purported public record, report, statement, or data compilation, in any form, is from the public office where items of this nature are kept.
 * ''(8) Ancient documents or data compilation. Evidence that a document or data compilation, in any form, (A) is in such condition as to create no suspicion concerning its authenticity, (B) was in a place where it, if authentic, would likely be, and (C) has been in existence 20 years or more at the time it is offered.
 * ''(9) Process or system. Evidence describing a process or system used to produce a result and showing that the process or system produces an accurate result.
 * ''(10) Methods provided by statute or rule. Any method of authentication or identification provided by Act of Congress or by other rules prescribed by the Supreme Court pursuant to statutory authority.

Rule 902. Self-authentication

 * Extrinsic evidence of authenticity as a condition precedent to admissibility is not required with respect to the following:


 * (1) Domestic public documents under seal. A document bearing a seal purporting to be that of the United States, or of any State, district, Commonwealth, territory, or insular possession thereof, or the Panama Canal Zone, or the Trust Territory of the Pacific Islands, or of a political subdivision, department, officer, or agency thereof, and a signature purporting to be an attestation or execution.


 * (2) Domestic public documents not under seal. A document purporting to bear the signature in the official capacity of an officer or employee of any entity included in paragraph (1) hereof, having no seal, if a public officer having a seal and having official duties in the district or political subdivision of the officer or employee certifies under seal that the signer has the official capacity and that the signature is genuine.


 * (3) Foreign public documents. A document purporting to be executed or attested in an official capacity by a person authorized by the laws of a foreign country to make the execution or attestation, and accompanied by a final certification as to the genuineness of the signature and official position (A) of the executing or attesting person, or (B) of any foreign official whose certificate of genuineness of signature and official position relates to the execution or attestation or is in a chain of certificates of genuineness of signature and official position relating to the execution or attestation. A final certification may be made by a secretary of an embassy or legation, consul general, consul, vice consul, or consular agent of the United States, or a diplomatic or consular official of the foreign country assigned or accredited to the United States. If reasonable opportunity has been given to all parties to investigate the authenticity and accuracy of official documents, the court may, for good cause shown, order that they be treated as presumptively authentic without final certification or permit them to be evidenced by an attested summary with or without final certification.


 * (4) Certified copies of public records. A copy of an official record or report or entry therein, or of a document authorized by law to be recorded or filed and actually recorded or filed in a public office, including data compilations in any form, certified as correct by the custodian or other person authorized to make the certification, by certificate complying with paragraph (1), (2), or (3) of this rule or complying with any Act of Congress or rule prescribed by the Supreme Court pursuant to statutory authority.


 * (5) Official publications. Books, pamphlets, or other publications purporting to be issued by public authority.

 * (8) Acknowledged documents. Documents accompanied by a certificate of acknowledgment executed in the manner provided by law by a notary public or other officer authorized by law to take acknowledgments.


 * (9) Commercial paper and related documents. Commercial paper, signatures thereon, and documents relating thereto to the extent provided by general commercial law.


 * (10) Presumptions under Acts of Congress. Any signature, document, or other matter declared by Act of Congress to be presumptively or prima facie genuine or authentic.


 * (11) Certified domestic records of regularly conducted activity. The original or a duplicate of a domestic record of regularly conducted activity that would be admissible under Rule 803(6) if accompanied by a written declaration of its custodian  or other qualified person, in a manner complying with any Act of Congress or rule prescribed by the Supreme Court pursuant to statutory authority, certifying that the record:

 * (B) was kept in the course of the regularly conducted activity; and
 * (C) was made by the regularly conducted activity as a regular practice.


 * A party intending to offer a record into evidence under this paragraph must provide written notice of that intention to all adverse parties, and must make the record and declaration available for inspection sufficiently in advance of their offer into evidence to provide an adverse party with a fair opportunity to challenge them.


 * (12) Certified foreign records of regularly conducted activity. In a civil case, the original or a duplicate of a foreign record of regularly conducted activity that would be admissible under Rule 803(6) if accompanied by a written declaration by its custodian  or other qualified person certifying that the record:
