I upload our will, the deed to the house and all other legal documents we keep at the bank safety deposit box, with our lawyer or at the house.
I added a label to each document as to where it is stored
and explained what each document contains and when they should look at it. And I shared it all with our children.
Now, if anything were to happen to us, our kids will have read everything in advance, know where to look and what to look for.
