If she is in the medical field or works on Wallstreet, then the debt can be managed. But the issue is that no one can really "predict" what's going to happen after you actually get married:
- What if she gets pregnant and decides to be a stay-at-home mom and "require" you to be a "real man" and work all day to pay all expenses and her debt?
In the example I provided, even if you had a Pre-Nup she could make a case that her skills have been destroyed through being a "stay at home mom" and the Judge could override the Pre-Nup as a whole or aspects of it, as well as give her Alimony. A Pre-Nup can never be iron clad, you can always structure one but you really have no idea if it's going to "insure you" until you are actually going through the divorce proceeding.
Me personally, I am NOT getting married. There's no upside benefits for a man with his life together, a solid career and future to get married. I am going to make children though for the sole reason of leaving a Legacy. This will be with a woman that fits my standards though, and I will structure my monetary sources so that if the worse case occurs with the woman trying to put me on child support, I have ways to show lower levels of income.
