Common questions
Frequently Asked
4
How does a party authenticate an item of evidence under the Federal Rules?+
A party must produce evidence sufficient to support a finding that the item is what the proponent claims it is. Testimony from a witness with knowledge or other methods listed in Rule 901(b) commonly satisfy this requirement.
What does authentication mean for a security agreement under the UCC?+
Authentication occurs when the debtor signs a written security agreement or attaches an electronic symbol or process to an electronic record with intent to adopt it. This step satisfies the formal requirement for an enforceable security interest.
Does failure to authenticate a document prevent its admission?+
Yes. Without authentication the court lacks assurance that the item is what it is claimed to be, so the evidence is inadmissible until the proponent supplies the required foundation.
Can electronic records be authenticated?+
Yes. A party authenticates an electronic record by attaching an electronic symbol or process with present intent to adopt the record, serving the same function as a traditional signature on paper.
