How to Write a Letter to Your Children: A Legacy Letter Guide

There are things most parents want their children to know — things that get lost in the daily rush of living, or that feel too important or too awkward to say out loud. A letter is where those things can finally be said.

A letter to your children is one of the most enduring gifts you can give. Here's how to write one that actually says what matters.

Why This Letter Matters

People who have read letters left by a parent describe them as among the most precious things they own. Not the furniture, not the money — the letter. Because it's the one place where a parent spoke to them directly, personally, outside of the demands of daily life.

These letters become more valuable over time, not less. A child reads a letter at 35 and again at 55 and hears something different each time. They share it with their own children. They read passages at difficult moments. They return to it when they need the voice it contains.

Before You Start: Let Go of Perfection

The biggest obstacle to writing this letter is wanting it to be perfect. It won't be. No letter is. The goal isn't eloquence — it's presence. Your child doesn't need the best letter ever written. They need to hear from you.

Write a draft. Write it badly. Write it in an afternoon. You can revise later. The most important thing is that you start.

Prompts to Get You Started

These prompts are meant to be starting points, not a checklist. Write from the ones that resonate and skip the rest.

About who they are

What do I most admire about who you are?
What quality of yours will serve you best in life?
What is one thing about you that I don't think you fully see yet?
What is a memory of you that I'll always carry?

About your relationship

What do I want you to know about how I felt being your parent?
Is there anything I wish I had said or done differently? Is there something I want you to understand about it?
What does our relationship mean to me?
When did I feel most proud of you?

About your own life (so they know you as a person)

What do you want them to know about your childhood or early life?
What is something you learned the hard way that you'd want to spare them?
What did you believe in most? What did you stand for?
What made you happiest?

About what you hope for them

What do you genuinely hope for their life — not what you expect, but what you hope?
What kind of person do you hope they become?
Is there something specific you want them to know if they face a particular hardship?
What do you want them to hold onto when things are hard?

An Example Opening

Starting is the hardest part. Here's one way to begin:

"There are things I've wanted to say to you for years that I never quite found the right moment for. I'm writing them down now because moments run out, and I don't want these things to go unsaid.

The first thing: I am so proud of who you are. Not of your accomplishments — though I'm proud of those too — but of who you actually are as a person. The way you [specific quality]. The way you [specific memory]. That's you, and it's remarkable."

What to Do With the Letter Once You've Written It

Store it safely — in a fireproof safe, with your estate documents, or in FinalKeepSake's secure vault with instructions for when and how it should be delivered
Tell someone it exists — your executor, your spouse, or a trusted person should know there are letters to be delivered
Consider the delivery — after your death? At a specific milestone? Both? Write your preference in the letter or in your estate documents
Revise it over time — a letter written when your child is 10 may want to be updated when they're 25. Revisit it every few years.

Writing Letters for Future Milestones

Consider writing letters for milestones you might not be there to witness:

Their graduation (high school, college)
Their wedding day
The birth of their first child
A difficult birthday (30, 40, 50)
A moment when they need to hear your voice

These letters, held and delivered at the right time, can be among the most meaningful gifts imaginable — your presence at a moment you didn't live to see.

Frequently Asked Questions

What should a letter to your children include?

The most meaningful letters to children include: something about who the child is and what you love about them specifically (not generically); what you hope for their life — not instructions, but genuine wishes; what you want them to know about your own life, values, or experiences; your feelings for them, stated plainly; and perhaps a piece of advice — one thing, not a list. The best letters feel like a conversation, not a speech. They are specific to that child, not interchangeable.

When should you write a letter to your children?

Now. The most common regret people express about legacy letters is not writing them while they had time. You don't need to be ill or elderly to write a meaningful letter to your children. Many parents write them as part of their estate and end-of-life planning, or at significant milestones. Some write one letter meant to be read after their death; others write letters for specific milestones (graduation, wedding, the birth of their children's first child) to be held and delivered when the time comes.

How long should a letter to your children be?

There is no right length. A heartfelt, specific one-page letter is more valuable than a generic five-page one. Most meaningful legacy letters are 1–3 pages. Some parents write a short letter for each child separately; others write a longer letter to all children together. The length that feels right is the one that covers what truly matters to you without padding.

What if I have multiple children — do I write one letter or separate letters?

Both approaches work. Separate letters allow you to speak to each child as an individual — acknowledging what is unique about them, your specific relationship with them, and hopes that are specific to their life. A combined letter can speak to your family as a whole, your values, and your wishes for your children collectively. Many parents write both: a shared family letter and individual letters for each child.

Should I give the letter to my children now or keep it for after I die?

That's entirely your choice. Some letters are most meaningful when read after death — they become a lasting artifact of your voice. Others are meaningful to share now, during your lifetime, and can open conversations and deepen connection. There's also a middle path: write the letter now, tell your children it exists, and choose whether to share it. Some parents write letters to be given at specific future milestones (a child's wedding, the birth of their first grandchild).
