That is a business plan for divorce. You are setting your self up. Instead of spending all your energy on the possibility of divorce, try to get to know your future spouse, and maybe you won't have to worry about a "corporate restructuring."
Why not do both?
"Maybes" are no way to manage your life in an adversarial legal environment. "Maybe" if your spouse loves you, he or she will see the wisdom in the idea that even a partnership based on personal feelings needs a set of guidelines - because what's left of the "institution of marriage" in these times transcends those feelings and gets government involved in your lives in a big way.
