profits from sole and separate property

With certain exceptions, all rents, and profits from separate property remain separate property, unless they are comingled with community property funds, i.e.: a community bank account.  As far as whether there is a community interest in his separate property asset, that is a possibility, but more facts would be needed.

Even though he owned the business prior to your marriage, in California, the non-owner spouse may possibly get a piece of the business based on the length of the marriage and other factors.  it depends on the circumstances.  

Right now you need to consult with a divorce attorney in your area.  You have rights and an attorney will help you to protect them.

Best of luck.
