"I am in the middle of a law suit with CACH,LLC They have sent me copies of credit card statements that they are sueing me over."
That explains the confusion. I wasn't asking you to identify the plaintiff. Rather, your use of "they" seemed out of place. The entity you mentioned is an "it." "They" is a plural pronoun -- i.e., it is used to refer to more than two persons, places, or things (e.g., Are Bobby and Brooke coming over to play? They are very nice.). Anyway...
Yes, any evidence will have to be authenticated before it can be admitted. And, since a credit card statement would be offered in order to prove the truth of the facts stated on the statement (i.e., that you owe the money as set forth on the statement), the creditor will need to lay a foundation for the business records exception to the rule against hearsay evidence.
