On March 7, 2019, Myrna M. DeLeon passed away, days before her 65th birthday. “Her death was completely unexpected,” said her daughter and my brother-in-law’s wife, Casey. In the emotional aftermath for the family, one thing made the grieving process less stressful: Myrna’s “in case of death” preparations. She had filed important documents in a safe and kept a categorized “little black book of information.”

“She was a nurse who was organized in the operating room, and she took that skillset of organization and advanced thinking into our home life as well,” Casey said. “For example, ‘B’ was not for people with the last name starting with B, but for banks and other financial institutions. It listed account numbers for policies and phone numbers to call for claims.”

Casey and her brother had set up their mom’s phone and email, so they knew her passwords for those, which proved essential. “All of her contacts were in her cellphone, and I needed those to inform them of Mom’s passing. I also needed to ask her colleagues how their union benefits worked so I could get answers as quickly as possible.”

Preparing for your eventual demise is a gift your loved ones will appreciate even as they mourn your loss — and it will give you peace of mind in the present, too. Most people have thought about setting up a will and doing other estate planning, but you should also arm your family with the most essential information they’ll need in the immediate days and weeks after you’re gone, preferably in one easy-to-access place. Here’s how to set up a digital version of Myrna’s “little black book” for simple and secure information sharing with family members and trusted friends.
