Imagine that you have a man who is a billionaire that gets married.. but he had his wife sign a prenuptial agreement that specified that she would only get $100,000 for every year that they had been married in the event of a divorce.  The reasoning would be that he wanted to be sure that the woman was not just marrying him for his money.

But then.. they have a child, and get a divorce 2 years later.  The woman would get her $200,000… but what about the child support for the child?  That could be astronomical! 
I wonder if that is why some celebrity spouses push so hard to adopt children.. so they can use them as a source of $$$ in a divorce?
