I have a notarized will, power of attorney, a page of final arrangements,copies of my financial statements, and my car title in a folder on my desk. My bank accounts have a TOD beneficiary on them and my car is paid off with a beneficiary listed on the title as well. I have a good friend who will get everything and I've done about as good of a job as I can at making sure they get it with as little trouble as possible and without having to go through the court process. These papers should be very easy to find when the time comes, but I may just give it to them beforehand and tell them to safeguard it "just in case". The only thing they should need to access everything is a death certificate - I'm sure they can scrape up the $20 if they need to.
Before I CTB I'll reset my computer to default settings and erase all of the data, won't bother leaving any online login info - they don't need it. I've left plenty of money to pay for a funeral (although I did mention in my final arrangements papers not to bother unless they felt it would help them grieve properly) and any legal expenses they incur. I'll need to clean up the house, and I'll probably need to get rid of as much junk as I can to make it easier for those I leave behind. I have bills paid up for a month in advance, so they won't need to rush to make the next payments. The important stuff is already taken care of, so if I do act on impulse one day it'll be alright.
I do have biological family who will not be happy that they aren't getting anything. They shouldn't expect to, since I haven't spoken to them in almost a decade, but they are the type of people who will throw a fit and cause as much trouble as possible. That's why I have beneficiaries set up on my car and bank accounts - they don't go through probate and there is no room for arguing that the beneficiary shouldn't receive it. I think the best I can hope for is that my blood relatives don't find out I'm gone for quite a while after my death, but I can't control every facet of my death so I just have to do the best planning I can.
