I am really happy to see that the custody portion is settled and that the results are sealed from public view. At the end of the day, Bryn will have access to both of her parents (and Grandma and Grandpa Hoppy) which is the best thing for her. It's up to BOTH of her parents (at this point) to be mature people and parent the right way.
From what my attorney friends have told me (that do work in this area), New York State is pretty strict when it comes to handling prenuptial agreements. They've told me that Jason's lawyers would have to mainly show that one - he signed his prenup under duress; two - that the prenup signed was not fair and reasonable at the time they were married (which no attorney worth their salt would open themselves up for that kind of malpractice) and three, that by her filing for divorce and ending the marriage she would leave him without a way to support himself (which we all know is not true). With their marriage being as short as it was and the imbalance of their fortunes prior to getting married, Jason's attorneys will have a very hard sell to a judge in New York County (aka Manhattan) to prove he's entitled to any of her money outside of what was agreed to within the prenup. And because this portion of the divorce proceedings are sealed, we'll never truly know what was agreed to unless someone leaks it. TL:DR? The only people I see getting rich here are their mutual attorneys.
With that being said? If I were Bethenny I would say screw it and pay Jason off. They were together for a grand total of (maybe) five years - including the time they were dating each other and the time they were married - with him coming in at the very tail end of her business exploding (she was building her business for several years before she ever met him so I don't see how he was even 10% responsible for taking Skinny Girl to the next level). And yes, they have a prenup and his actions (to me) throughout this whole thing scream "I am thirsty" so I get why she is fighting for her money. I say give him enough so he can buy all the water he wants. Even better - give him the damn apartment or put it up for sale so that the proceeds will have to be split. Regardless of what we may think of her, she's always been a hustler - she can and will make more money doing something else. He'll fade back into obscurity, trying to be Captain Save-a-Ho for some other damaged soul. They'll really only have to see each other and/or communicate for Bryn's sake, and all of that will probably be worked out between their lawyers as part of the settlement. And maybe I will see him around selling fancy drugs when I go into Manhattan to see my doctor. ;)
