I was reading this article A North Carolina man just won U$S 750,000 lawsuit after suing his wife lover which mentions men earning figures such as U$S 750,000 or even U$S 8,800,000 for suing his wife's lover. Do laws like this exist in any other western country? And by western I mean the definition of western world which includes Europe, Canada, Australia and New Zealand.
