The legacy letter: leaving your family more than money

A good estate plan is a careful, practical thing — a valid will, powers of attorney, up-to-date super nominations, and a clear record of where everything is kept. If you've done all that, you've done your family a real kindness, and most of our estate-planning articles are about getting exactly those pieces right. But there's one more thing worth leaving, and it's the one families tend to treasure most of all. It isn't legal and it isn't financial. It's the answer to a question your will can't address: who were you, what did you believe, and what did you want us to carry forward? A legacy letter is how you leave that. This article is general information only, not personal, legal, or financial advice.

What is a legacy letter?

A legacy letter — sometimes called an ethical will — is a personal letter (or a few of them, or even a recording) to the people you love, in which you pass on the things that aren't property. That means your values, the lessons life taught you, your memories and family stories, your gratitude, your hopes for your children and grandchildren, and often the why behind the decisions you've made. The tradition is ancient — people have left ethical wills for centuries — but there's nothing formal about it. It's simply you, in your own words, saying the things that matter. It sits comfortably alongside the more structured "record your wishes" work that bodies like Advance Care Planning Australia encourage, where writing down your values and preferences is treated as a gift to the people who'll one day have to speak for you (Advance Care Planning Australia, https://www.advancecareplanning.org.au/start-planning/think/values-and-preferences).

What is it not — and why does this part matter?

Before we go further, one thing has to be crystal clear, because getting it wrong causes real problems. A legacy letter is not a legal document. It has no legal force. It cannot leave anyone an asset, it cannot change who inherits what, and it does not replace or override your will, your powers of attorney, or your superannuation death benefit nominations. A will, by contrast, is a legal document that sets out what you want to happen to your assets when you die, and it's only one part of a proper estate plan (ASIC MoneySmart, https://moneysmart.gov.au/manage-your-money-in-retirement/get-help-in-retirement/wills-and-powers-of-attorney).

So if there is something you want to happen — who receives your home, who gets what share, who should care for a dependant — that belongs in the proper legal document, drawn up with your solicitor. Write "I'd like my daughter to have the house" in a legacy letter and, on its own, it achieves nothing legally. The letter is where you might gently explain why you've made the arrangements you have; the will is where those arrangements are actually made. Keep the two jobs separate, and the letter can't accidentally cause confusion or a dispute.

Why is it worth writing?

With that caveat firmly in place, here's why so many people find this the most valuable thing they leave. Years from now, your family will rarely reach for the will — but a heartfelt letter in your own hand (or your own voice) gets read, and re-read, and passed around. It's how the people you love keep you.

It does practical good, too. A letter that gently explains the thinking behind your estate — why things were divided as they were — can soften hurt feelings and head off resentment, in a way a bare legal document never could (while, again, the binding decisions stay in the will). And it passes on something that otherwise simply vanishes: your judgement, your humour, your history, the advice you'd want to give. Many people find that writing it is quietly good for them as well — a chance, late in the day, to work out what really mattered.

What should you put in one?

There are no rules, but if a blank page is daunting, a few prompts help. Many people start with the values and principles they tried to live by, then move into stories and memories — how you met your partner, the lean years, the funny moments, where the family came from. From there it's natural to offer a few lessons and pieces of advice, gently rather than as instructions, and to say the things we all assume people already know and so rarely say out loud: gratitude, and love. Some people use the letter to offer forgiveness, or to ask for it. Almost everyone writes down their hopes for their children and grandchildren. And if you wish, you can set out the reasoning behind your estate decisions — as explanation, never as instruction, because the instruction itself lives in the will.

How do you write one?

Don't overthink it. Sincerity matters far more than polish — this doesn't need to be beautifully written, it needs to be true, and a plain, honest letter is exactly right. Write it however suits you: one letter, separate letters to different people, a notebook, or a video or audio recording if words on a page aren't your way.

A few gentle pointers. Be honest but kind — it may be read many times over the years, so write nothing you'd regret leaving as a last word, and never use it to settle a score. Date it, and feel free to revisit and update it as life moves on. And make sure it will actually be found: tell someone you trust where it is, and keep it with your important papers but clearly marked as separate from — and not part of — your legal documents, so no one ever mistakes it for the will itself.

Where does it fit — what are the three layers?

The neatest way to think about it is that getting your affairs in order has three layers. There's the legal layer — your will, powers of attorney and nominations, which decide who gets what and who can act for you (ASIC MoneySmart, https://moneysmart.gov.au/manage-your-money-in-retirement/get-help-in-retirement/wills-and-powers-of-attorney). There's the practical layer — the record of where everything is, so your family isn't left hunting (our article on the emergency information folder covers that). And there's the personal layer — this letter, which passes on who you are. It's a close cousin of advance care planning, which is really the same instinct pointed at your future health: writing down, ahead of time, what you value and what you'd want, so the people who love you aren't left guessing (Advance Care Planning Australia, https://www.advancecareplanning.org.au/understand-advance-care-planning/what-is-advance-care-planning). Most people manage the first layer, some manage the second, and almost nobody does the third. Do all three and you've left your family something close to complete: your affairs settled, your information findable, and your voice still with them.

What do the worked examples show?

These show how the letter and the will do different jobs — and why keeping them in their own lanes matters. They are illustrative only, not personal, legal, or financial advice.

Consider Margaret, 74, a widow with three adult children and a modest estate — her home and some super — that she intends to split equally. She's already made a valid will with her solicitor doing exactly that. What's been weighing on her is something the will can't hold: she wants her grandchildren to know how she and her late husband built their life from very little, and why she's always insisted the family stick together. On these facts a legacy letter is precisely the right tool, because none of what she wants to pass on is an asset or an instruction — it's memory, values and love, which carry no legal weight and need none. It's generally sensible for someone in Margaret's position to write freely and warmly in the letter, and to leave every binding decision where it already sits, in the will (ASIC MoneySmart, https://moneysmart.gov.au/manage-your-money-in-retirement/get-help-in-retirement/wills-and-powers-of-attorney).

Now consider Robert, 70, who has decided to leave a larger share of his estate to one of his two sons, because that son gave up years of work to care for him. Robert's instinct is to write a heartfelt letter explaining the decision and calling it settled. Here's the trap: a letter cannot make an unequal split happen — if it isn't in the will, it doesn't bind, and an uneven arrangement left only to a letter is exactly the kind of thing that breeds a family dispute. On these facts the rational move is the two-part one: put the unequal division itself in the will with the solicitor, so it's legally effective, and then use the legacy letter to explain the reasoning gently, so the other son understands the "why" rather than being blindsided by it. The letter softens; the will decides.

What should you do in short?

Your will takes care of your money and your property, and it should — put every binding wish in it, properly, with your solicitor. But when that's done, consider sitting down and writing the other inheritance: the letter that tells your family what you believed, what you're grateful for, and what you hope for them. It has no legal power and it doesn't need any. It's simply the part of you that no document could ever distribute — and very often, it's the part they'll hold onto longest.
