I have a general question. So please read the situation below and provide some direction if possible.

In a lawsiut if the defendant did not answer the plaintiff's questions under Request for Admissions in the required timeframe (60 days from day served in state of Texas) Does the defendant have any options? Since the plaintiff cannot produce the credit card application I have found several Texas Annotated Statues stating the plaintiff must have the contract in order to sue. But the plaintiff is using the fact the questions were not answered as a way to state the defendant acknowledges their was a contact.
