It's really not a problem if you have normal relations with your family.

That is the importance of communication to build family harmony.
Even though I currently don't have many assets, I have shared everything related to ownership of these assets with my wife. I teach my wife about cryptocurrency, so we work together to make a profit from this ecosystem. She knows what to do if any time I leave the world first, I have also prepared some important notes for access to all my wallets.
It is very important to have a partner you can count on to help you.
