The Supreme Court of Canada recently refused to hear an appeal in LeVan vs. LeVan, thereby passing up a splendid chance to undo mischief done by Ontario's lower courts.
Putting it bluntly, the bride had two options: either sign the contract and get virtually none of the husband's money, or not get married at all -- in which case she would obviously get none of the husband's money. Note that both options included the part about not getting any significant amount of the husband's money. Therefore, how could it have mattered whether she knew the dollar value of his assets, since she wasn't going to get any of them either way? Zero percent of any number is still zero.
