My wife signed a premarital agreement (PMA). They are not as bulletproof as you think, but they are certainly better body armor. Do your own research about PMA's. I hired a female attorney known for representing women in a divorce who were married to relatively high net worth, high income men. I had her write the PMA. What she pointed out was insightful. She told me that main reasons PMA's get thrown out is that they were egregious at the time of signing. It may be egregious later on based on circumstances but it can't be egregious at the time of signing. 20 years later I'm in the middle of a divorce. It's not bullet proof but I'm much more protected than if I did not have one. Sounds horribly pragmatic, but before you get married, I would go to the NOLO online bookstore and read all their books on divorce. If I told you that buying a house had a 50% of loosing half its value, and you should by all the books you can about buying a house, I guarantee you that you'd buy all those books.
