I've been happily married twice.....if you have something you want to protect make her ass sign a prenup. Don't listen to the marriage is forever bullshit because divorce statistics say that's not the case. Your little honey bunch turns into a cut throat bitch and will try to take the shirt off you back and leave you for dead.
Like was said above, make sure you get a lawyer to write it and make it air tight because even with prenups they still have a way of getting at your shit.
good luck with the wedding
