How to Leave Instructions for Your Family (Letter of Instruction)
The short answer
You leave instructions for your family in a letter of instruction: an informal, non-legal document beside your will that says who to call, where documents and accounts live, how to access them, and what you wanted. It needs no lawyer or witnesses — write it in plain words, date it, and make sure it will be found.

You leave instructions for your family in a letter of instruction — an informal, non-legal document that sits beside your will and tells the people you love, in plain words, who to call, where everything is, and what you wanted. It needs no lawyer, no witnesses and no filing. You can write it tonight, on paper or in a document, and change it whenever life changes. The will handles what a court must enforce; the letter handles everything a court will never care about but your family desperately will.
That division of labour is the whole idea. A will is read weeks after a death, once it's located and probated. A letter of instruction is read the same day — which means the decisions your family faces in the first seventy-two hours are the ones the letter exists to carry.
Why the will alone is not enough
A will is a legal instrument. It names an executor, distributes property, and moves at the speed of probate. What it doesn't do is answer the questions a grieving family asks first:
- Who should we call tonight — and who will want to hear it from us directly?
- Where is the will itself? The deeds? The insurance policies?
- Which account pays the mortgage? Are there debts we don't know about?
- What did they want for the funeral — burial or cremation, which place, which people?
- Is there anything they wanted us to understand, in their own words?
Ohio State University Extension, which has published estate-planning guidance for decades, puts it bluntly: there is no legal requirement for a letter of instruction, and it is not legally binding — "it can contain whatever you wish, and it can be typed or handwritten." That sounds like a weakness. It's the entire point. Because the letter has no legal force, you can write it yourself, in your own voice, and update it as often as life demands.
What to include in a letter of instruction
A good letter of instruction is organized around what your family must *do* first, not around document types. Financial institutions and estate attorneys (Fidelity's estate-settlement guidance is the standard reference) converge on roughly the same ten areas:
1. The first calls
Names and numbers for the people who should hear it directly: close family, friends, your faith community, your employer or business partners. Then the professionals: your lawyer, accountant, financial advisor, insurance agents, and the funeral director if you've chosen one.
2. Where the documents live
The will or wasiyya, powers of attorney, deeds and titles, birth and marriage certificates, recent tax returns, insurance policies, bank and investment statements. Not the documents themselves necessarily — the *locations*, written so a tired person can follow them: "the grey folder in the study drawer; the originals are with our lawyer, whose number is above."
3. The financial map
Every account, policy and asset, with institution, account or policy number, and how to access it. Include the half most people forget: debts in both directions — what you owe (mortgage, loans, anything personal) and what is owed to you. A debt your family doesn't know about becomes a surprise claim against the estate; money owed to you is simply never collected. We covered this in what happens to debt when you die.
4. Access and the digital estate
How to get into the essential accounts and devices — email first, since every password reset flows through it. Store credentials securely, never in the same document as the account list if the letter is on paper. (The full picture is in what happens to your passwords when you die.)
5. Debts, bills and the monthly machinery
Which payments run on autopilot, from which account, and what must not lapse — insurance, utilities, the rent. The first month after a death is exactly when missed payments compound.
6. Funeral and final wishes
Burial or cremation, the place, the people, the tone. Any prearranged or prepaid plans, with the paperwork location. Details for the obituary, if you want a say in it.
7. Personal property and the sentimental map
Who should receive the items that matter emotionally more than financially — and why. This is where letters earn their keep: a will distributes value; a letter distributes *meaning*, and it can head off the small disputes that probate fights are made of.
8. Pets
Who should take them, how they're cared for, the vet's details.
9. Explanations, not just instructions
If a decision might surprise or hurt — an unequal division, an excluded relative — the letter is the place to say why, in your own words. It isn't binding, but an honest explanation is often the difference between acceptance and a family rift.
10. Personal messages
The part no legal document can hold: what you want each person to know. Some families write these as separate letters, one per person, sealed and named.
The three rules that keep a letter safe
Estate guidance from Fidelity, Trust & Will and university extension programs all stress the same three cautions:
- Never contradict the will. The will wins every disagreement, so a letter that promises the coin collection to your nephew when the will says otherwise doesn't change anything legally — it just hands a grieving family a reason to fight. If a wish matters enough that someone might resist it, it belongs in the will, not the letter.
- Date every version. An undated letter invites arguments about which version was current. Update it when life changes — a new account, a new child, a divorce, a death among your people — and at least once a year.
- Make sure it will be found. A letter nobody knows about is the same as no letter. Keep the original where your family would look within a day, give a copy to your executor, and tell the people who'll need it that it exists. One place it should *not* live alone: a bank safe-deposit box, which is often sealed at death until a court orders it opened.
Letter vs. will: the division of labour
| | The will | The letter of instruction | |---|---|---| | Legal force | Binding; enforced through probate | None — guidance only | | Written by | Usually with a lawyer | You, tonight, in plain words | | Updates | Formal amendment or rewrite | Edit and re-date, any time | | Carries | Who gets what, executor, guardians | Who to call, where things are, what you wanted | | Read when | Weeks after death | The day it's needed |
The two are companions, not rivals. Many people state in the will that the executor should consult the letter — which gives the letter standing without making it a legal battleground.
Where WiseEnding fits
The letter of instruction is the right *idea*; paper is the fragile part. It goes stale, it lives in one drawer, and it can't tell the difference between "share this today" and "only if something happens to me."
WiseEnding keeps the same arrangement alive: your accounts, debts, documents and access instructions in one private place, sealed with zero-knowledge encryption so even we can't read them — and Trusted Access plates that decide, per person, what each of your people can see now and what stays sealed for them. The Legacy Heartbeat answers the "when": you check in on a rhythm you choose, and only if you ever go silent does the system release what you prepared — gently, with reminders and a grace period first — each person receiving exactly what you meant for them. And the letters themselves, the personal messages in your own words, live there too, addressed to each person who matters. (The mechanism is explained in what a dead man's switch is, and the bigger map in what a family vault is.)
A will tells the law what you decided. A letter of instruction tells your family what to do next — and what you hoped for them.
Write the will with a professional. Write the letter yourself, this week, and re-date it every year. The hour it takes is one of the kindest things you will ever do for the people you love.
