Seventy percent of divorces are said to occur over money. A lot of people go into marriage without knowing about each other's assets and debts. The prenup provides a structure for disclosing that information. Like professional counselors advise good communication for great sex, I advise full financial disclosure for lasting marriages. They stimulate communication and compromise.
Money is a big bugaboo.
People don't like to talk about it. Once you start to talk about money, it opens the door to honest and open discussions in other sensitive areas and strengthens the emotional bond. People think prenups cause divorce. That's as silly as saying health insurance makes you sick. A prenup increases the chances of an everlasting marriage because you've already done a lot of the hard work.
