Beware of the "I love you" will. There are many of these around and until one spouse or the other dies they are fine (with the possible exception of failing to utilize a marital deduction trust.) These wills are where each spouse leaves everything to the other spouse. However, when one or the other dies the survivor should draw a new will to designate new beneficiaries. Failing to do so is very like having no will at all.

Good point. In the wills I write I designate beneficiaries at least three levels....first to, then to, and then to... I think most attorneys do the same.
Especially in case both spouses die in a common accident.
