To protect assets from a divorce,
Many people would say, do not marry in the first place, Thats pretty annoying thing to drag on if you met a really good submissive girl espically when you get older.
I'd say have your risks in check before you get married, forget the prenup, sometimes they don't work or not useful if your assets aren't above 5MM++
Move everything out from your name into corps you control or brothers you trust or mothers you trust, or fathers you trust , (this is if you have money) , if you don't why bother? both of you are doomed.
b. Leave around $250k -500k in your control
Pretty simple, Sure she'll take 1/2 the house or the house when she leaves, but thats to be expected.
As I said, have your risks already claculated. If you don't want your house taken, have it in your brothers name, or transfer it. If you don't have a brother or a living parent, use a corp. with advisors.

I'd say the loss should be already calculated before you enter the agreement of marriage. Just like a trade.
