I have never been married before. He has. He has a ton of debt from the past and lots of expenses with child support. Therefore, the debt is not going away in the near future. Although I am happy to do the 'what's mine is yours' as we both work to pay it off, am I liable for his debt should, as my boss used to say, 'he gets hit by a bus' the day after we're married? If so, is there a prenup that protects me from being liable for debt he acquired before we marry?
