Part of the reason for keeping it so very simple and using just a 3 fund portfolio is so your spouse or someone with very limited experience and interest can continue to manage it.
I keep a book called for lack of a better name "my death book" and in there is all the information my wife will need when I go somewhere else. And a couple of pages are about how to manage our investments. I even include what to do if the market drops 10, 20, 30, 40, and 50%. When and how to re-balance. When to get more conservative. And why to manage it this way. What to do if she feels she can't manage it. How to un-freeze the credit reports, living will, when to turn off the machines, what to sell and what to keep. Even have anticipated values for land and other owned assets.
I have even written my own obituary and provided the deeds to our burial plot. Even who to officiate, who to hold the funeral, and have even purchased and installed the headstone.
