Dear Family, I hope this note finds you well. I wanted to take a moment to share some important information with you that will help you take care of things if I'm not around.

I have a life insurance policy with ABC Insurance. The policy number is 123456789. Please reach out to ABC Insurance at 123-456-7890 if you need to file a claim. I have a mortgage with DEF Bank. The mortgage account number is 123456789. If you need to make payments or have any questions, you can reach out to DEF Bank at 123-456-7890.

The passwords of my online accounts are in the section named 'sensitive information' below.

Finally, I have a safety deposit box at GHI Bank. The key to the box is in the top right drawer of my home office desk.

Everything they'll need. All in one place
