The Art of Her Deal: The Untold Story of Melania Trump by Mary Jordan:
Prenuptial and postnuptial agreements are as standard as wedding rings in Trump’s marriages. His first wife, Ivana, renegotiated hers three times; Marla, who separated from Trump after four years of marriage, walked away with such a relatively small sum that even a Trump lawyer said he felt she should have gotten more. Trump wrote about prenups and boasted about them and said any rich man who didn’t have one was “a loser.” During the presidential campaign, Melania felt that a lot had changed since she signed her prenup. She had been with him a long time—longer than any other woman. She believed she made crucial contributions to his success. There was talk that Trump likely wouldn’t return to overseeing the Trump Organization after running the country, and Melania wanted to ensure that Barron got his rightful share of inheritance, particularly if Ivanka took the reins of the family business.
While she sorted out her plans as first lady and a new school for her son, she also worked on getting her husband to sign a more generous financial deal for her and Barron. It was smart timing. “The best thing you can do is to deal from strength, and leverage is the biggest strength you can have,” Trump wrote in The Art of the Deal. “Leverage is having something the other guy wants. Or better yet, needs. Or best of all, simply can’t do without.” While in New York, Melania had new leverage. The vacant first lady’s office annoyed him. He wanted her with him.
