In the simplest situations, after your death, you leave your money outright to your spouse if he or she is living. Then, when your spouse passes, they leave the remaining money to your children. This assumes a straightforward family scenario, perhaps with only one marriage involved. Ideally, everyone is experienced with money management, has happy and stable relationships themselves, and there are no major personal issues to worry about. The ideal and uncomplicated situation is rarely the real family dynamic.
