Is a company started by my husband before marriage and its assets non-marital?

maybe, maybe not. i know that is not the answer you want but the answer is not that simple. it may be his non marital property but contributions to it during the marriage may be required to be reimbursed to the marital estate. much more information and many papers are needed to give you a better answer. go see a good divorce lawyer in your county. you are in du page? there are a few members of the american academy of matrimonial lawyers there. go to aaml.org to do a search.

This is not a simple yes or no question. There are many factors which contribute to the determination of whether an asset is marital. You really need to consult with an experienced family law practitioner. If you are headed for divorce, you need an attorney anyway and you might as well be prepared with good legal representation.

Your question cannot be answered until many more facts are known.There is a whole line of appellate court cases.that address your situation and what rights you may or may not have. Consult with a divorce lawyer.
