You may also want to keep a back up of your wallet, and you also might want to have instructions for heirs in the event of your death. These are not easy questions or problems to solve, to the extent that you might either want to make sure you don't lose your seed words due to some kind of natural disaster (fire or something), and that you have some preference to passing your coins to heirs rather than dying with them.
There won't be any attorney that will distribute your bitcoins to your next of kin after your death, one has to do it himself. There are lot of bitcoin lost forever because of owner losing the keys or due to death of owner. This is something one has to take very seriously, if you have Bitcoins then you must inform your next of kin how to use them after your death. Make sure your hard work is not wasted once you leave this world.
Surely some folks have attorneys or other people they trust in their lives with the most intimate of details, and there can be a variety of ways for persons to make sure that they have some kind of a successorship system in place. Trusted persons might have some or all of the material, and trusted persons might not even know the complete contents of the materials that they hold if there might be a sealed envelope or a safe or maybe there would be instructions to contact another trusted person (named Benny) for further instructions or for other parts of the puzzle.
i am not suggesting that there is any ONE correct way, even though I am suggesting that some people may well not end up adequately putting systems in place or keeping the information up-to-date if there might be some papers with passwords, there might be a failure to update the sheet after some of the passwords end up needing to be changed.
