Get legal advice. Before you go, sit down and make a thorough list of marital assets, including pensions etc. Then make a list of debts, mortgages etc.
As for the business - you say you are a "silent partner"? Does that mean you put money into the business? Did the funds to start it come from marital assets? Is your name on any business loans? You definitely need an attorney to figure out the best way to deal with the business - these things get complicated.
