As I understand it, in CA, where I live, it's a community property state and a no fault state. Means basically ALL assets acquired during the marriage are equally owned. Exceptions are gifts. This will include your businesses as well. Divorce attorneys LOVE to go after businesses, claiming their value to be much higher than they often are. This happened with me. Also, your retirement would be divided equally as well. In CA, there isn't any formula for permanent spousal support. There are guidelines the court is supposed to consider. They are CA. Family Code Section 4320-4325. There's no reason to think that more than 50% of your income would go toward spousal support. The court will determine her income and your income and attempt to equalize them according to Section 4320-4325. Selling the home, if you do not want to keep it, will be not so easy in the current economy. I chose to buy out my ex's equity and kept the home. This avoids the sale costs but you will be responsible for all the tax when you sell. A consultation with an att. will not be held against you by the court. By your ex, probably.
