If you've got a wife, a girlfriend, and an adult daughter from a prior marriage, don't die intestate. Because if you do, your estranged wife -- from whom you've been separated for 12 years -- will file a claim for a huge chunk of your estate, your girlfriend will file a palimony and other claims, and your daughter will seek her share as well. And they'll fight, fight, fight -- for years -- over your former material possessions. And try to hose each other every step of the way.
Is this really what you want as your legacy?
