I live in Wisconsin as well. I have beaten Cap 1 in Wisconsin.
Look at Wisconsin Statutes Chapter 801.
You also need to look at the Wisconsin Consumer Act, Google it. Esp. look at Chapter 425, esp. sections 425.104, 425.105, 425.109.
Some county courts have online manuals for small claims court. If yours does not, look it up on your favorite search engine.
That being said, you need to know a few things about defending a case in Wisconin.
Kohn NEVER sends out a 15 Day Notice of Right to Cure Default. This is in violation of Wisc. Stats. 425.104 and 425.105.
I ALWAYS demand a full accounting, as per 425.109(2). If they do not provide it, they cannot win.
I beat Cap 1 because they used a robo-signing "agent" for their affidavit. Look up the case Kalal v. Palisades
In Wisconsin, you can file a MTC arbitration for your answer, or so I have heard. You might want to include an answer as well, such as answer all of their claims with "DENY", except you admit you are John Doe living at 1001 Main St., Point Place, WI, for example. (That was the town in That 70s Show).
You need to be careful dealing with Kohn. They are all very good lawyers, especially the lawyer monitoring this post. :-)
Seriously, they are a very good firm.
Cap 1 has JAMS in their arbitration agreement. I filed in JAMS against Cap 1, and they folded. The judge had thrown out their evidence, they had nothing, and they were not going to spend thousands of dollars chasing their tails.
Especially since you are completely broke.
Cap 1 has a provision that you can write and ask they to pay your $250 JAMS fees. If they ever get around to it, they will send you a form where you show how broke you are.
