Letter of Wishes: What It Can Explain, and What It Cannot Control
A practical U.S. guide to writing, reviewing, securing, and updating a letter of wishes without contradicting a will, trust, beneficiary designation, or legal directive.

A letter of wishes can preserve your voice, explain priorities, and help the people handling your affairs find information quickly. It can be valuable precisely because it is usually more personal and easier to revise than a will or trust.
But a letter is not a quiet substitute for a valid estate-planning document. It generally cannot redirect property, appoint a fiduciary with legal authority, override a beneficiary designation, amend a trust, create a health-care directive, or guarantee how a funeral will be handled.
Use the letter to illuminate the plan, not to rewrite it from the side.
This is a U.S. general guide. The legal effect of a writing depends on state law, its wording, the governing document, and how it was signed and delivered. Have an estate-planning lawyer review the letter together with the will, trust, powers of attorney, directives, and beneficiary designations.
Decide which kind of letter you are writing
“Letter of wishes” can mean several different things:
- a personal explanation to family members;
- guidance to a trustee exercising discretion;
- practical instructions for an executor or agent;
- a care summary for a dependent person or pet;
- preferences for a memorial, belongings, or digital legacy; or
- a document index explaining where formal records are stored.
Name the audience and purpose at the top. Mixing emotional messages, confidential financial details, trustee guidance, and emergency instructions in one letter can make the whole document harder to use and harder to protect.
Consider separate letters when the audiences differ. A trustee may need financial context that grandchildren should not receive; a caregiver may need routines but not account balances.
Understand the nonbinding boundary
The American Bar Association cautions that a letter of instruction or general preferences does not itself supply the dispositive language required for a will. A request framed as “I hope” or “I would like” may create a moral expectation, but it does not reliably transfer property.
Some trust laws and trust instruments allow a fiduciary to consider a letter of wishes when exercising discretion. For example, Delaware has codified circumstances in which a fiduciary may consider such a letter, while making clear that it is not binding. That does not create a nationwide rule.
Write with the assumption that the governing legal document controls. If you want a result to be mandatory, ask the lawyer whether it belongs in the will, trust, deed, beneficiary designation, contract, directive, or another state-authorized instrument.
Reconcile the entire estate plan first
Put the current documents side by side:
- will and codicils;
- revocable and irrevocable trusts and amendments;
- powers of attorney;
- advance health-care directives;
- deeds and entity agreements;
- life-insurance and retirement beneficiaries;
- transfer-on-death and payable-on-death registrations;
- prenuptial or postnuptial agreements; and
- any state-specific disposition-of-remains document.
The letter should not identify a different executor, beneficiary, distribution percentage, or mandatory use of property unless the controlling instrument supports it. Review the current estate-plan checklist before drafting explanations around an outdated plan.
Explain reasons without creating a new condition
A letter can explain why one child received a business interest while another received liquid property, why charitable giving matters, or why equal economic value did not produce identical assets. That context can reduce speculation.
Avoid language that sounds like a new bargain: “She receives this only if…,” “He must…,” or “The trustee shall…” If the condition is important, it needs legal review and may belong in the governing instrument. Informal conditions can conflict with the plan, invite disputes, or ask a fiduciary to do something unlawful or impractical.
Use first-person context: what you considered, what values guided the signed plan, and what you hope the recipients understand. Do not diagnose, accuse, punish, or disclose unnecessary private history.
Give a trustee context, not secret commands
Where a trust grants discretion, a letter may describe factors the settlor hopes the trustee will consider: education, health, housing stability, disability supports, entrepreneurship, substance-use recovery, or preservation of public benefits.
Tie the guidance to the discretion actually granted. Do not tell the trustee to ignore the trust, favor someone the document excludes, or promise distributions. State that the trustee should follow the trust and applicable law and exercise independent judgment.
Discuss with counsel whether beneficiaries may receive the letter, whether later versions can be considered, and whether the trust expects intent contemporaneous with its execution. A candid letter may someday be reviewed in litigation; write facts you can defend.
Treat personal-property wishes carefully
Families often value personal items more emotionally than financially. A letter can record stories, preferences, and a suggested order for distributing photographs, jewelry, furniture, art, or heirlooms.
Whether a separate list can legally direct tangible personal property depends on state law and the will’s language. Ask counsel whether your state recognizes a signed list, what property it may cover, and what formalities apply. Do not place real estate, cash, securities, business interests, or beneficiary-designated assets on an informal keepsake list.
Use clear descriptions and current photographs. Include a process for conflicts (rotation, drawing lots, valuation and buyout, or sale)only if the executor has authority to use it.
Put funeral preferences where they can be found in time
A memorial or disposition preference is useless if discovered after arrangements are complete. State law may determine who has authority over remains and may offer a specific form for naming that person or recording binding directions.
Keep immediate contact details and preferences where the responsible person can access them promptly. Tell that person the document exists. Review prepaid funeral contracts, cemetery rights, veteran benefits, organ donation, religious practices, budget, and the person authorized to decide.
Do not assume a paragraph in the will or letter controls. Ask a local lawyer which state-specific document carries authority and whether a copy should be given to the chosen agent or funeral provider.
Keep health-care wishes in formal directives
A letter can add personal context, but it should not replace an advance directive, living will, health-care proxy, HIPAA authorization, or physician order required by state law and medical circumstances.
The American Bar Association notes that all states permit people to express end-of-life treatment wishes and appoint someone to communicate when they cannot, although names and formalities vary. Execute the proper documents and give usable copies to the agent and relevant clinicians.
If the personal letter mentions care values, say that formal directives and medical orders control. Review those documents after a diagnosis, move, divorce, death of an agent, or change in wishes.
Separate access information from passwords
A useful letter may identify banks, advisers, insurers, digital services, document locations, safe-deposit boxes, and people to contact. It does not need to expose every credential.
The Consumer Financial Protection Bureau recommends organizing important financial records and keeping password and PIN information separately in a safe place. Use a secure password manager or other attorney-approved access plan, and tell the authorized person how to locate it when permitted.
Never put passwords, alarm codes, seed phrases, Social Security numbers, full account numbers, or copies of identity documents in a letter that may be widely copied. The digital-account access guide explains why authority and platform rules matter even when credentials are known.
Build a practical document index
The most useful page may be an index rather than prose. Include:
- lawyer, accountant, adviser, insurance professional, and primary physician contacts;
- location of originals and who holds copies;
- trust, entity, insurance, retirement, and real-property record locations;
- safe-deposit box location and key custodian;
- recurring household obligations and property risks;
- location of the secure digital-access plan;
- people or organizations needing prompt notice; and
- date each category was last verified.
Keep this index with the organized records described in storing the documents that matter. Use partial account identifiers only when needed to distinguish accounts.
Write for a stressed reader
Use short sections, direct sentences, and headings that answer a question. Separate “required by my legal documents,” “preference if practical,” and “background only.” Do not make the reader infer which statements are mandatory.
Include names and relationships, not vague references such as “the usual adviser.” Explain specialized property, family circumstances, animal-care routines, or cultural practices without assuming the reader already knows them.
Avoid legal jargon copied from documents. The lawyer drafts legal effect; the letter should make the practical and human context easier to understand.
Date, sign, version, and retire old copies
Place a clear date and version number on every page. Identify which earlier letters it replaces. Sign it if counsel recommends doing so, and keep evidence of when it was delivered to the intended recipient.
When updating, retrieve or clearly revoke old copies. Conflicting versions can be worse than no letter. Do not make silent handwritten edits in the margin of a stored copy.
Review after a marriage, divorce, death, estrangement, reconciliation, move, major asset change, new diagnosis, trustee change, or amendment to the estate plan. A simple annual check can confirm that names, contacts, locations, and preferences remain current.
Protect capacity and freedom from pressure
If the letter explains a sensitive or unequal plan, prepare it when capacity is clear and outside the pressure of a beneficiary. Tell the estate-planning lawyer about family conflict, dependence, isolation, coercion concerns, or a major last-minute change.
Do not use a family member who benefits from the explanation as the only typist, witness, custodian, or messenger. The lawyer may recommend contemporaneous notes, an independent meeting, or other evidence appropriate under state law.
The goal is not to make the letter look like a will. It is to preserve reliable context without creating doubt about the formal plan.
Store it for the right audience
Ask the lawyer whether the original should sit with the estate plan, be held by counsel or trustee, or be delivered separately. Give emergency information to someone who can access it before probate begins. Do not lock the only funeral or care instructions in a safe-deposit box no one can enter promptly.
Use an access list: who has the letter, which version, and for what purpose. A personal family message can remain sealed while an operational index is available to the nominated fiduciary.
Privacy continues to matter after death. Limit medical, financial, and family details to what the intended reader genuinely needs.
Review it as if you were the fiduciary
Before finalizing, ask:
- Which statements are binding, and where is that authority found?
- Does anything conflict with the will, trust, title, contract, or beneficiary form?
- Is the requested action legal and within the fiduciary’s power?
- Are urgent instructions accessible before court appointment?
- Does the letter reveal passwords or unnecessary private information?
- Can every named person, document, account, and location be identified?
- Is it obvious which version is current?
- Would the language reduce conflict, or provide new material for it?
Have the estate-planning lawyer answer the first three in writing or annotate the review file. Then let a trusted nonbeneficiary reader test the operational sections for clarity.
What the completed file should contain
Keep the final letter with:
- counsel’s review date;
- a cross-check against governing documents and beneficiary designations;
- the version and revocation history;
- a recipient and location list;
- separate secure credential instructions;
- copies of any formal disposition or health-care directives; and
- a future review date.
The letter succeeds when it helps people execute the actual plan accurately and compassionately. It fails when it asks goodwill to do the work of legal authority.
