Pre-nuptial agreements can help, providing they are VERY well drafted so as to be enforceable not only in the state where they were drawn (and you married), but in the jurisdiction you're living at the time of the divorce and (if there are significant assets involved) in each jurisdiciton where you have assets.

The problem is that some courts will reform the agreements or declare them void against public policy depending on the fact situations.

Pre-Nups are an area where only the best will do -- hire a real matrimonial expert as your attorney to draw it, not your regular trusts and estates lawyer or general practitioner who would draw your will. If you move to a new state, consult an expert in the new state as to the enforceablity of your Pre-Nup. And you will need to take special precautions if you are moving to (or living in) California, Texas, Louisiana or the other 'community property' states in which all earnings and assets aquired by a couple during the marraige are considered jointly owned 50/50.

Which creates a self-fulfilling prophesy at the outset of a marriage...
