Exhibit Authentication: FAQ Guide
Proper authentication is required before exhibits can be admitted into evidence. This guide covers foundation requirements, self-authenticating documents, and how to overcome common objections.
Frequently Asked Questions
What does it mean to authenticate an exhibit?
Authentication means proving the exhibit is what you claim it to be. Under Federal Rule of Evidence 901(a), you must produce evidence sufficient to support a finding that the item is genuine. Common methods include witness testimony, distinctive characteristics, chain of custody, and certification.
What are self-authenticating documents?
Self-authenticating documents under FRE 902 don't require extrinsic evidence of authenticity. These include: certified copies of public records, official publications, acknowledged documents (notarized), commercial paper, certified business records, and newspapers/periodicals.
How do I lay foundation for a business record?
For business records under FRE 803(6): establish the record was made at or near the time of the event, by someone with knowledge, kept in the regular course of business, and it was regular practice to make such records. A records custodian or qualified witness typically provides this foundation.
What if opposing counsel objects to authentication?
If an authentication objection is sustained, you need additional foundation. Options include: calling another witness with personal knowledge, using circumstantial evidence (distinctive characteristics, context), producing certifications, or asking for a stipulation. Prepare backup authentication for crucial exhibits.
Can I authenticate electronic records and emails?
Yes. Email authentication under FRE 901(b)(4) can rely on distinctive characteristics including email address, writing style, content references, and metadata. Business records certification under FRE 902(13)-(14) can authenticate electronic records without live testimony if properly certified.
Do I need to authenticate demonstrative exhibits?
Demonstrative exhibits (charts, summaries, diagrams) don't require authentication in the traditional sense, but you must establish they fairly and accurately represent what they purport to show. The creating witness or a qualified expert typically provides this foundation.
