Morning starby, I think that's lovely and jd's post is the same. It is a different set-up though, if you are starting out as you both were, building your lives together from your young marriages. However (as happened with me) I remarried in my 50s when I already had my own life and assets, I had worked blooming hard on my own for them - and acknowledging that things can go wrong, I needed to protect those assets, just in case things went pear-shaped. If one of you is far more wealthy that the other (which sounds the case for the OP) then the rich one doesn't want the other partner to be able to claim pensions and assets if the marriage does fail. I know it sounds as if people are thinking of failure from the outset, but divorce and separation seem very common these days and we all have to protect our own interests for the future. My OH and I share everything to do with our current relationship, but just in case it goes awry, there is something there to say what we bought to the marriage beforehand.
