It becomes difficult for other people to find your papers and other things after you pass away. It is a good idea to get organized, if you want to help them, according to the Washington Post in "Let's talk about the Big Book: Everything your family needs to know when you die."
People who are not fastidious about putting everything away in its proper place, end up doing this with all sorts of important documents over the years.
One suggestion discussed is to put copies of all important documents in a three-ring binder. This includes your will, any other estate planning documents and advanced medical directives. It should also include documents about important possessions, such as vehicles and financial accounts. Any important legal or financial documents should be included.
If you ever need to locate one of your important documents for yourself, the organization will be helpful. Doing this will also help to reduce the difficulties for your family after you pass away.
