It doesn't have to be about distrust, but being humble enough to admit that one cannot predict future events that can have an effect on ones marriage. And whether one should marry or not has little to do with the question of prenup in a marriage.cmonkey wrote: I think if the thought of a prenup comes to your head before you get married, you probably shouldn't even be getting married. It implies that there is a level of distrust between the two parties, even if its just a little bit.
My parents got married and had me. They truly believed their marriage would last forever (I mean, who doesn't?) Should they therefore never get a prenup? They ended up divorcing and it got very messy. Did they both wish they had signed a prenup? Yes. Does this happen to many couples every day? Yes. Can it be avoided with a prenup? Yes.
With your logic no one should get married then. They all believe they will defy statistics, yet some are doomed and sometimes neither party can be blamed. Prenups can help avoid a lot of mess for many. The cost of a prenup is very low. I don't intend to burn down my house, but I still have an insurance.
I was once in a car in Turkey. Upon putting my seatbelt, the driver got offended. He thought I didn't trust him as a driver. I found that attitude to be a bit arrogant.
