Most people have a rough idea of what they own, who their doctor is, and where their important documents live. But if you were in a hospital tomorrow and couldn't speak for yourself, would your family know any of it?
The hard truth is that most families don't. Not because they don't care, but because this kind of information lives in people's heads, buried in filing cabinets, or scattered across inboxes. When something goes wrong, the people who love you are left scrambling at the worst possible time.
This guide is about fixing that. It's not morbid. It's practical. And it doesn't take as long as you think.
Start with medical: it's the most urgent
If you're rushed to a hospital, there are five things the medical team needs to know right away: your doctor's name, your current medications, any allergies, your insurance information, and who to call. Everything else can wait. These five things cannot.
Write down your primary care physician's name and phone number. List every medication you take, with the dose. Note any allergies, especially to medications or anesthesia. Find your insurance card and write down the member ID and phone number on the back. Then choose one emergency contact, ideally someone who is calm under pressure and knows where you live.
That's the 20-minute version. Do it this week.
Financial accounts and bills
Your family doesn't need your account numbers; they need to know who to call. The goal here is not to store sensitive data, but to create a map.
Write down the names of your banks and roughly what each account is for (checking, savings, investment). List your regular bills (utilities, subscriptions, mortgage) and who they're with. If you have a financial advisor, write their name and number. If you have life insurance, note the insurer and policy number.
The person managing your affairs after something happens will need to notify these institutions. Having a list saves them weeks of detective work.
Legal documents
Three documents matter most: your will, a power of attorney, and any advance healthcare directive (also called a living will). You don't need all three to get started, but you should know which ones you have, where they are, and who the named parties are.
If you don't have a will, that's a separate conversation. But for the purposes of this guide, your job is to record where the documents are stored (attorney's office, filing cabinet, safe), who the executor is, and whether anyone has a copy.
If you have a safe or strongbox, record where the key is. If your will is with an attorney, record their details. Don't assume someone will figure it out.
Digital access
This is the one people forget. Your email is often the key to everything else; it's used for password resets, account recovery, and most financial correspondence. Your family needs enough of a hint to get in, or to know who can help them.
You don't need to write down passwords. You need to note whether you use a password manager (and which one), what your primary email address is, and any important online accounts your family might need access to, such as online banking, investment platforms, and subscription services.
If you have digital assets or online businesses, note those too.
People and pets
The last section is the most human. Who should be notified if something happens? Who takes care of the dog? Who picks up the kids?
Write down the names and numbers of the people who matter most. Note any dependents: children, elderly parents, anyone who relies on you. If you have pets, write down the vet's name, any medical needs, and your preference for who should take them in.
This sounds simple. But families have fallen into conflict over exactly these questions when someone didn't leave instructions. A paragraph now prevents a problem later.
Keep it somewhere accessible
All of this only works if someone can find it. A document on your phone that's locked, a note in a filing cabinet that no one knows exists, or a file on your computer with a password no one knows: these don't help anyone.
Tell at least one person you trust where this information is. Better yet, share it with them directly through a service that controls access, so they have it when they need it and it stays private until then.
