I set up a file in my regular filing cabinet called “Will”. I gave the executor of my estate a letter that outlines where everything is with information about where to find things like updated passwords, the keys to my safe deposit box etc. Everytime I updated something I just stick it in the “Will” folder and then about once I year I go through and clean everything up to make it easy for her to find. I keep a list of ideas for funeral planning, etc. so that she would know what I would want. It’s not as formal as some people have but it’s a much bigger step forward than most people have.
