Divorce or the breakup of a long-term domestic partnership at your age can be especially devastating, both emotionally and financially. It's hard to start over at midlife and it's difficult to recover from the inevitable legal expenses without dipping into your nest egg. Reduce the negative financial consequences of your breakup with some clear, businesslike thinking about the money decisions you need to make now. It's not always easy, but it's possible. Making the hard decisions now, during the breakup negotiations, will help make sure you're secure later, when you're older.
