My sister signed a pre-nup. He is worth at least a billion. It made sense. Especially since thew were both over 40.
What I prefer over a prenup, though, is marriage options as I’ve heard some states do:
Marriage type A - what we seem to have in most of the country today. Also where a no-fault divorce would probably be the norm.
Marriage type B - called a “covenant marriage”. In this case, you don’t get to ask for a “no-fault” divorce. Kinda like the old days.
So, type A marriages can be ended like a partisan impeachment can be passed. Type B marriages also require the equivalent of the Senate Trial, but where the opposite “party” has a majority position. i.e. if only one of you wants the split up, it’s gonna require murder. ;)
No fault divorce is stupid.
Or even better, what I advise my clients is this: Have a commitment ceremony, live together, take each other’s names if you want, but for god’s sake do NOT get a license. Then when it is over, you just walk away.
