And here is the crux of the issue. You took the lion's share of the property at the divorce, but who earned the money? Were you both working, or were you raising kids at home, or were you relaxing at home while he worked his butt off? Now, if this were a community effort on a business you both started, this split would be fair (as he "had disposed of a great deal of money and property without my signature". No question there.
If you were home, raising kids; again I would agree with the settlement. In that you had sacrificed earning an income to raise a family.
However, if you were working part time, no kids, and at home, relaxing by the pool, watching Soap Opera's and lounging about; this was unfair.
The law does little to differentiate, but there is a world of difference in my book. For example, remember Johnny Carson's divorces? His wive's are taking home millions/yr for life. They did NOTHING (maids did the housekeeping). Johnny took the risks, put in the hours and used his talents. His wives provided little more than sex and companionship, and that's mighty expensive companionship.
