You need representation in this divorce to protect your rights. You should immediately interview local experienced divorce attorneys and hire the one you believe is right for you.
In general to your question: Wisconsin is a marital property state. Property brought to or acquired during the marriage, with some exceptions, is considered marital and to be divided equally. However, I cannot give you legal advice and there are many exceptions to the rules. Again, please get legal help as soon as possible.
