Legacy planning sounds like something that requires a lawyer, a financial advisor, and several afternoons you don't have. It doesn't. The most valuable documentation most families are missing is surprisingly simple — it just requires someone to actually write it down.

Here are five things that nearly every family should document, most of which take no more than an afternoon to complete.

1. The location and access details for critical financial accounts

When someone close to you dies, the first practical challenge isn't grief — it's paperwork. Bank accounts need to be closed or transferred. Insurance policies need to be filed. Retirement accounts need to be claimed. Debts need to be identified.

Most families attempt to do all of this without a roadmap, spending months hunting through old mail, calling institutions to verify whether accounts exist, and piecing together a financial picture that the deceased person knew completely and never wrote down.

A simple document listing your major financial accounts — bank accounts, investment accounts, insurance policies (with policy numbers), retirement accounts, and any real property or significant debt — is one of the highest-impact things you can create. It doesn't need to include account numbers or passwords. It just needs to tell the people you trust what exists and where to look. Keep it somewhere accessible — not locked in a safe that no one can open.

2. The stories behind the objects that matter

Families fight over objects after a death — not because the objects are valuable but because no one can agree on what they meant. The grandmother's ring matters because of who gave it to her and when. The old watch matters because of the relationship it represents. Without the story, it's just metal.

For the objects in your home that carry meaning, write down three things: what it is, where it came from, and who — if anyone — it should go to. Photograph it. This takes a few minutes per item and creates a record that will prevent conflict and preserve meaning for generations.

You don't need to catalog everything. Start with the dozen objects that have the most history or emotional weight. The rest can be dealt with as general property.

3. Medical history that your family may need

Hereditary conditions, chronic illnesses, surgeries, and medications are the kind of information that becomes urgent when a family member is sitting in a hospital emergency room and can't provide their own history. Doctors ask about family medical history for good reason. Most people can only guess.

A basic medical summary — major diagnoses, current medications, allergies, emergency contacts, and primary care provider information — is genuinely life-saving in the right circumstances. It also matters at routine moments: knowing whether heart disease or certain cancers run in your family shapes screening decisions for decades.

You can start with just your own. If you can get a similar summary from your parents, even better.

4. What you want people to know about your life

This is the one most people skip because it feels awkward or abstract. But it's arguably the most important. Every person has formative experiences, core values, and hard-won lessons that shaped who they are. Most of that dies with them — not because it's secret, but because they never found a moment to write it down.

A legacy journal doesn't have to be a memoir. One entry answering a single question — "What do you want your grandchildren to know about how you lived?" or "What was the hardest thing you ever had to decide, and what did you learn from it?" — is enough to start. Write it when the feeling is there. Add to it over time.

Future generations will read it and understand things about their family that they couldn't have known otherwise. That kind of continuity is rarer than it should be.

5. The practical instructions for what happens after you die

Location of the will. Name of the estate attorney. Whether you want burial or cremation. What to do with the house. Whether there's a funeral home you've pre-arranged with. These are the decisions families are left to make under stress without guidance, and the stress is multiplied by not knowing what you would have wanted.

A single document — even a two-page letter — that covers the major practical questions saves the people you love from having to guess while they're grieving. Write it once. Update it when something changes. Put it somewhere they can actually find it.

The thing most families get wrong

The problem isn't that families don't care about leaving this information. It's that they think there's more time than there is. The average person who dies unexpectedly didn't expect it. The average family who loses a parent without a documented legacy didn't think that's how it would go.

None of these five things require a specialist. They require an afternoon, a willingness to write things down, and a decision to do it before the moment when it becomes urgent.
