IndyStar:  “Now the company that shopping-mall tycoon Melvin Simon built is becoming legally entangled in the family feud over the late billionaire's will.  Indianapolis-based Simon Property Group, the world's largest publicly traded retail estate company, filed a complaint Monday in Hamilton Superior Court against Simon's widow, Bren Simon.  She is seeking to convert about 6.5 million shares of ‘partnership share units' in the family trust into common stock or cash.  The amount of stock or cash was not specified.  The company, in its complaint, said the shares cannot be converted because they are tied up in a legal challenge to Melvin Simon's will by Deborah Simon, a daughter from a previous marriage.”
