To prenup or not to prenup

I don’t have a lot of my own mottos. But one of them is ‘I’ll sign everything but a prenup.’

This is absolutely only if I marry someone who makes more money than me.

But anyways what do you think about prenups? I’m nosy. If you’re married do you have one? What does it say? Do you trust your lawyer? Would you take half of your partners earnings and assets? Have you?
