Mark Zuckerberg married his long time girlfriend A DAY after Facebook shares started trading. A DAY after he was officially declared worth $19 Billion. Under Califonia law, that wealth will be considered pre-marital wealth and the wife is not entitled to even a dime of it!
Even then though, Donald Trump still hopes Zuckerberg had Priscilla Chan sign a pre-nup. He [Trump] confesses he is dirt cheap when it comes to such matters. He'll try to pay the lowest amount possible in case of a divorce! Makes sense.
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
