after having watched my father go through 3 divorces with in 10 yrs, with children or not i would have to say get a "prenup", regardless of how long/short the marriage is you can lose a shit-ton of money, for instance my dad's last marriage of 2 years cost him a little more than half a million, due to being accustomed to living lavashly, they judge ordered my dad to pay....I thought it was total bull shit, so irregardless prenup is a must!
