Do you have a Judicial Separation?
As I understand it, the assets and property gained prior to you getting a Judicial Separation are "fair game" and can be counted when calculating maintenance, entitlements etc. However, if you don't have a JS then it's free to the wind.
I would get some firm legal advice on this one, it's very hard to tell which applies. If you're still in the dark, try putting a post on the Separation/Divorce board on rollercoaster, you might get a better and more informed response there.
