Yeah I used to have a massive spreadsheet tracking the entirety of household finances. I was worried that no one would know where the money was if I suddenly died, so I started a monthly finance 1:1 with my spouse. Even wrote an "upon death or incapacitation" playbook for her.
The second session was just her saying WTF I can't keep track of the location, ownership and tax benefits of 40 accounts!
I've since closed 3/4 of all accounts because of that.
