What can i do to defend myself froma credit card lawsuit?

Well first, you would need to provide a great deal of specifics related to the transaction and potential concerns you have to see if they are legal defenses that need to be raised. Unfortunately, there is no "just say this and they'll go away" defense inherent to any credit card legal action. There ae usually a variety of legal defenses to look at ranging from statutes of limitatio, standing, proper parties (due to assignments etc) to lack of proper evidence to support the claim, but they all typically turn on the facts of each case. I typically find that people are best served to hire an attorney to defend these cases if at all possible rather than handle on thier own, as they often find themselves wanting to hire lawyers after a judgment is entered, which is more expensive and less effective. In addition, I often find that other issues may exist such as violation of the collections practices acts (Florida and FDCPA) that may exist as counter claims or separate claims.
