The prenup exists regardless, just you chose to use the one the state creates for you. The existence of the prenup has Jack shit to do with an escape hatch. But I have a very positive networth, a house and a business that I built before the marriage. Coming from a divorced family, and the statistics of divorce say getting a prenup is smart, it in no way insinuates I want the marriage to end, in fact the opposite. It means if it were to end, things should go back to the way they were before the marriage.
A prenup doesn't make divorce more of an option. No one starts a marriage thinking they'll divorce. But both of us come from divorced parents so we're not naive that it COULD happen to anyone. If the incentives of a prenup are setup to make it easier to leave then you have a fucked up prenup. In our context, I have multiple businesses that revolve around my home because it's farming, I also will inheret property from my family. In the prenup I really just want the house and the businesses to remain mine because otherwise I would have to start a new farm from scratch which in my mind means I would simply leave farming. All of the other assets built up during the marriage still become common property, but the things I had before aren't. Round number example, cash stored in the mattress) . If I had 100k before the marriage, then 10 years into the marriage I have 1 million. I basically would leave with 5.1 million. This is fair.
