Well, you can save your seed phrase so it can be passed after your death. Or pass it before that to your relatives whom you want to get your BTC. I suppose there are also many ways to do this, but I couldn't come up with them, I don't have such plans anyway.
There are, I don't also have plans yet but I have given the idea to my family on what I've written on the piece of paper and why I am taking care of it.
I've told them that when I die, they can take it and do some research but never give it to anybody that will say that they're going to help them.
They should be the one to retrieve and do the importing of it to the wallet that they will be able to find as genuine to access my wallet.
