How to Write a Legacy Letter

A legacy letter tells someone what you've learned and what they mean to you. Use these prompts to write a personal letter and decide when to share it.

Think of someone you care about and something you've never quite told them. It might be why their help mattered, how you came to hold a belief, or what you learned from a difficult choice. Put their name at the top of the page and write about that.

The thought of leaving words behind can make even a familiar subject hard to write about. You don't have to account for your whole life. A letter about one thing you want someone to understand is enough to begin.

What is a legacy letter?

A legacy letter is a personal message about your experiences, values, and hopes for someone else. It's also called an ethical will. Stanford Medicine describes it as a way to pass these thoughts to family, friends, or your community.

The word "will" can be misleading. Cornell's Legal Information Institute explains that an ethical will has no legal significance. Use the appropriate legal documents for decisions about your property or medical care.

You can write to a friend, a partner, a younger relative, or someone you've mentored. CancerCare notes that you can write an ethical will at any point in life and revise it as your values change.

Choose the person before the subject

Picture the person reading your letter. What would you like them to know that they might not already understand? A letter to your sister may need a different explanation from one intended for a grandchild.

For a first draft, choose one question from the list below. These prompts draw on topics suggested by Stanford Medicine and CancerCare. Follow the question that brings a particular memory or thought to mind.

  • What do I appreciate about this person that I haven't said clearly?
  • Which experience changed something I believed?
  • Who helped me, and what did that help make possible?
  • What mistake would I like to explain in my own words?
  • What do I hope this person feels free to choose for themselves?

Explain what you mean with a memory

Words such as kindness or courage tell the reader more when you connect them to something that happened. Describe an occasion you remember, then explain why it stayed with you. If a detail is uncertain, say so or leave it out.

You might write about advice you resisted and later understood, or a decision you would make differently now. There is no need to make every experience sound like a lesson you mastered.

Write as you would speak to this person. If a sentence sounds too formal when you say it aloud, use the words you'd use in conversation. You can rearrange the draft after you've worked out what you want to say.

Leave room for their choices

Advice can become a demand without the writer intending it. Reread passages about marriage, work, faith, or family obligations. Explain why a choice mattered to you without telling the recipient they owe you the same choice.

CancerCare urges writers to consider their words carefully because they may not be there to explain them. Look for comparisons between relatives, accusations, or passages written to settle an old argument.

If you want to apologize, name what you did and take responsibility for it. Leave the reader free to respond in their own time. A trusted person can help you spot wording that may land differently from how you intended.

Make a plan for sharing it

Decide whether to give the letter now, when you can talk about it together, or save it for later. Put the recipient's name and the date on the version you want them to receive. If someone else will deliver it, tell them where it is and when to share it.

Mark an updated letter clearly so an earlier draft isn't mistaken for the version you intended. If speaking comes more naturally, CancerCare suggests making an audio or video recording.

Before you share it, check that you've actually said the thing that brought you to the page. A thank-you can remain a thank-you. You can write another letter when you have something else to say.
