The plan nobody talks about

Those cover what you own. They say nothing about how any of it works.

Which account pays the mortgage. Which card the deductible goes on. The email address that everything else resets through. That layer is real, it is used constantly, and for most people it has never been added anywhere.

It isn’t carelessness

The systems that hold your accounts are built so that only you can reach them. That is working as intended — it just means the record of what exists has to come from you. Nobody can reconstruct it later from the outside.

Three ordinary situations

None of these are disasters. They are Tuesdays that got complicated.

• A hospital stay you didn’t plan. Someone needs your insurance details and your doctor’s name, and you are not in a position to go looking.
• A trip where you’re hard to reach. A payment fails at home. Someone would need to know which account it came from.
• An estate, months later. Accounts nobody knew about, each platform handling it differently — a list you could have written in an afternoon.

What a plan actually is

Not a vault, and not a weekend project. A written record of where things are and who to call — built one answer at a time, and yours to stop whenever you like.

Naming someone you trust doesn’t hand them anything. They’re asked whether they’re willing, and that is the whole ask.
