In his $6.6 million divorce settlement two years ago, big shot real-estate lawyer Steven Simkin (pictured) paid his ex-wife Laura Blank $2.7 million to buy out her half of their Madoff investment, which he thought was worth $5.4 million. Now, according to his attorneys, the "account" is worthless, "literally not worth the paper on which the parties' valuation rested." So Simkin wants some of that money back, because "Laura has been unjustly enriched, having received millions of dollars based on an illusory and exaggerated value attributed to the 'account.'" Blank, who works for CUNY, tells the Post she isn't really feeling Simkin's pain: "What he's doing is outrageous. He made a poor investment choice and it's his problem." Just as every bum's lot in life is his own responsibility, regardless of who he chooses to blame!
