These kinds of non-monetary agreements aren't binding in court, and in fact they could cause a judge to take your entire prenup less seriously. Rather than including personal matters in your prenup, you may find it helpful to simply make a list of your most important concerns and discuss them together. If you want to take it a step further, you can underscore your commitment by writing down your personal agreements in a separate document -- perhaps in a letter that each of you writes to the other, clarifying your intentions and wishes. This may help avoid misunderstandings and keep expectations clear but, a Judge isn’t going to enforce them for you.
