Phase 4 · The Just-In-Case Binder

Fill It In

4 screens · do this offline

The "fill it in offline" workflow.

The template Cowork built in the last lesson is sitting in your Just-In-Case Binder folder as Binder-Template.md. Now you fill in the placeholders — by yourself, in a text editor, with Cowork closed. The sensitive bits never pass through any AI.

  1. Open the template file directly

    Navigate to ~/Documents/Claude/Projects/Just-In-Case Binder/Binder-Template.md in Finder (Mac) or File Explorer (Windows). Open it in any plain text editor — TextEdit, Notepad, VS Code, anything that reads markdown files. Make a copy first if you want to keep the original template clean: save the working copy as Binder.md in the same folder.

  2. Fill in placeholders one section at a time

    Work through each [FILL OFFLINE: ...] placeholder. Type in the actual information. Save as you go.

  3. Don't paste the filled-in version back into Cowork

    Cowork doesn't need to see what you typed in. If you want help with a specific section (figuring out what providers count as "professionals" or how to phrase something), you can ask Cowork generic questions — but don't paste in your actual account numbers, SSN, or other sensitive details to get help.

Tips for the sections that tend to trip people up.

You don't need a section-by-section walkthrough for most of it — the placeholders make it obvious. A few that are worth a heads-up.

Financial accounts

Last-4 only. Not the full numbers. For each account, write the bank name, account type (checking / savings / credit / brokerage), last-4, and roughly what it's used for. The actual logins live in your password manager, not in the binder.

Digital life — the password manager line

Don't write down any individual passwords. Write down: which password manager you use (1Password / Bitwarden / Apple Keychain / etc.), where it lives (the app on your phone and computer), and the recovery information for it — where the master password is stored (a sealed envelope in your home safe, for example, or with a specific trusted person). The binder points to the password manager; the password manager holds the actual credentials.

Pets & kid routines

This is where you write the stuff a babysitter or visiting family member would otherwise need you on the phone for. Bedtime routines per kid. The dog's food schedule. The cat's anxiety meds. Which kid needs the night-light on a specific setting. The pediatrician's after-hours number. Be specific — the value of this section is that someone reading it cold could actually run your household.

Legal docs section

You're not writing the documents in here — you're writing that they exist and where they are. "Will: drafted by [attorney name], original in home safe, copy with [attorney]." "Healthcare directive: signed [year], original in home safe." If you don't have these documents and would want them, that's a separate piece of work with an estate attorney.

Final wishes — opt in fully or skip cleanly

Either capture what you'd want known (funeral preferences, who should be called first, anything else) or leave the section out entirely. Half-filled feels worse than blank. There's no right answer here — both choices are reasonable.

Where the finished binder lives.

Once it's filled in, the binder needs to be findable by someone who isn't you. The general pattern: one digital copy + one printed copy + the originals of the documents the binder points to, each in a sensible place.

The three-locations rule

For critical originals (passports, birth certificates, marriage certificate, the will, healthcare directive, deed/title): keep at least one accessible copy in three different places. That way no single fire / flood / lost-keys event takes everything.

  • One at home — in a fireproof safe if you have one, or a single drawer everyone in the household knows about.
  • One off-site — bank safety deposit box, parent's house, attorney's office, or a trusted family member's home.
  • One digital — scanned PDFs in a password-protected cloud folder. The password to that folder lives in your password manager, which the binder points to.

The binder itself — physical + digital

  • Printed copy in a physical binder at home — easiest for a trusted person to actually find and use. Keep it in the same place as the home safe or the fireproof box.
  • Digital copy on your computer — the markdown file in your Just-In-Case Binder folder is the source of truth. Update it there, reprint when changes are significant.
  • Optional encrypted backup — if you keep an encrypted backup on a USB drive or in a password-protected cloud folder, your trusted person can access it if something happens to the home copy.

The binder doesn't need to be in a vault. It needs to be findable. A locked drawer with a key on a hook nearby is plenty for the binder itself. A fireproof safe is better for the originals. Use what fits your house.

What's next.

The binder exists, it's filled in, and the originals are where they need to be. Two things left, both covered in the next lesson.

The next (and last) lesson covers

  • Tell at least one person it exists. A binder nobody knows about is the same as no binder. The conversation matters more than the document.
  • Annual update. Lives in life change; binder needs to keep up. Once-a-year rhythm is enough for most people.
