Second the Get a Will idea, most assuredly. And while you're at it, make a note as to where the important papers are (deeds to the house, car titles, etc.), where everything is (where your checkbook(s) is/are, spare keys), which bank you use, doctors, dentists, relatives and friends to notify in case of.... - everything someone who's taking over in case you and/or Mr. Bossman get suddenly too sick to think will need.

Trust me on this. My father was exceptionaly well organized, and his list was very, very helpful after his death.
