Congratulations! Here's hoping you make the no-divorce club!

For us it's 30+ years without a divorce. I was 2 years out of college, she was just out of college, so we had no assets either. We merged everything (except the 401k -- can't merge that). Even all our credit cards are joint.

We went through pre-marital counseling.... and we talked about finances. Both of us came from parents who did have financial issues, so this was a serious topic to us -- more to my wife who felt her parents were borderline committing financial infidelity.

So while we didn't bother with a prenup, we did make a couple financial agreements...

1. no spending more than 100 dollars without talking to each other first. That's $250 in today's dollars...and we've adjusted the rule a few times since.
2. no deal is so good we don't wait til tomorrow.

That second one... remember 30 years ago there were no digital mobile phones and no web browers.

I wouldn't bother with a prenup .. what's fair in your case? (And it's easy for him to get around the prenup -- just skip the country...right?)
