This case is not unique and is very commonly the reason prenups are ditched. Either the husband or wife decides to be clever with a prenup at the last minute when the guests have arrived and the hall has been paid.
There is also the other part of the equation, nobody goes INTO marriage with the anticipation of divorce. Thus the added burden is one of "It will not matter because we are not getting divorced."
In this case the husband was just plain stupid. IF she had the agreement reviewed by a lawyer, even had terms modified at her request no matter how small, he would have been in a much better position to argue upholding the prenup.
When you buy stock, when you go to the track you KNOW the deal you are getting into. (insider trading aside) Here the woman was planning a big wedding, and from out of no where came this legal document that she would either sign or cancel the rest of her life.
Hahahahahahaha! Stop, I can't breathe, where's my oxygen tank? Hoohoohoohoohoo!!!
