Generally, an authenticating witness supporting the admissibility of business records under the business records exception to the hearsay rule under Rule of Evidence 803(6) need not have personal knowledge of the creation of the record or the contents of the record. But what the witness usually would seem to require is knowledge of business processes used to create the record and the chain of custody of the record. The records presented also would need to have been kept in the ordinary course of business.
