Foundation
The preliminary showing required before evidence can be admitted. Establishes relevance, authenticity, and reliability.
What You Need to Know
Laying foundation involves proving: (1) authentication (the document is what you claim), (2) relevance (the evidence makes a fact more or less probable), and (3) compliance with evidentiary rules (no hearsay unless exception applies). For business records, foundation requires testimony that records were created in the regular course of business, at or near the time of the event, by someone with knowledge per Federal Rules of Evidence 803(6).

Frequently Asked Questions
What is the foundation for business records?
Business records foundation requires showing: (1) the record was made in the regular course of business, (2) it was the regular practice to make such records, (3) the record was made at or near the time of the event, (4) the record was made by someone with knowledge, and (5) the custodian or qualified witness can attest to the business records procedure. This satisfies the hearsay exception under Federal Rules of Evidence 803(6).
Can I lay foundation without a witness?
Some evidence is self-authenticating and requires no witness foundation, including: certified public records, official publications, newspapers, trade inscriptions, commercial paper, and acknowledged documents per Federal Rules of Evidence 902. Most other documents require witness testimony to lay foundation.
What happens if I cannot lay proper foundation?
Without proper foundation, the court will sustain objections and exclude the evidence. You cannot use the document to support motions, cross-examine witnesses, or argue to the jury. Always identify and prepare foundation witnesses before trial and ensure you have declarations or testimony to authenticate each exhibit.
