How to Use Letters of Intent in Your Estate Plan

How to Use Letters of Intent in Your Estate Plan

To use a letter of intent in your estate plan, add it alongside your will or trust to leave personal, practical guidance for your family and fiduciaries that those legal documents do not cover. If you are building an estate plan or managing significant wealth and want your wishes understood and carried out with less confusion and conflict, this is where you explain details like where to find the safe deposit box key, why you chose one child as trustee over another, or which grandchild should receive your grandmother's wedding ring.

Used well, a letter of intent is not a legal document. It complements your will or trust by spelling out your preferences, key financial and logistical details, and the reasoning behind important decisions so loved ones, executors, and trustees have clearer direction during a difficult time. The rest of this article explains what a letter of intent is, how it differs from formal estate documents, what to include, how it can help prevent disputes, and how to write, update, and integrate it with your overall estate plan.

Key takeaways about letters of intent in estate planning

A letter of intent (also called a letter of instruction or final wishes letter) is a non-legal document that guides your loved ones and fiduciaries after your death or incapacity. It fills gaps that formal legal documents were never designed to address.

  • A letter of intent clarifies personal wishes for executors and trustees, serving as a practical guidebook alongside your will or trust.

  • It is not legally binding but provides guidance that fiduciaries usually give significant weight when making discretionary decisions.

  • Letters of intent should complement legal documents like wills and trusts - never replace them.

  • A practical benefit includes reducing family stress, preventing disputes over personal belongings, and explaining the reasoning behind your estate planning decisions.

  • At Third Act Retirement Planning, we encourage every client with a will or trust to pair it with a letter of intent tailored to their family and values.

With only 24% of American adults reporting that they have a will, the gap in supplemental guidance documents like letters of intent is even wider.

What is a letter of intent and how does it fit into your estate plan?

A letter of intent is a written roadmap that explains your wishes, priorities, and practical details that do not belong in formal estate planning documents. Think of it as the personal layer that makes your legal plan understandable to real people under real pressure.

  • Common alternative names: letter of instruction, side letter, letter of wishes, or ethical will. Each term carries subtle differences in emphasis, but all serve a similar purpose - providing additional context for executors or trustees.

  • Who it's addressed to: your executor, successor trustee, financial power of attorney agent, or your family as a whole.

  • Legal standing: courts do not treat it as a legally binding document, but a well-prepared letter of intent serves as a guidebook for executors and trustees navigating discretionary choices.

  • What it covers: a letter of intent is typically used to address issues not captured in formal legal documents - from the location of your home safe to the values behind your charitable giving.

At Third Act Retirement Planning, we coordinate letters of intent with our clients' attorneys so every piece of the estate plan works together rather than creating confusion.

They appear engaged as they discuss their final wishes and specific instructions for their loved ones, highlighting the importance of creating legally binding documents to provide guidance for future generations.

Letters of intent vs. formal estate planning documents

Understanding the difference between legally binding documents and a letter of intent is crucial for putting together a complete estate plan.

Core legal documents in a typical estate plan:

  • Last will and testament

  • Revocable living trust

  • Durable financial power of attorney

  • Health care power of attorney and advance directive

  • Beneficiary designations (life insurance, retirement accounts)

These estate planning documents control legal ownership, appoint fiduciaries, and authorize decisions. They must meet state law formalities - signatures, witnesses, and sometimes notarization. Unlike a letter of intent, they carry the force of law and override any informal guidance that conflicts with their terms. Formal requirements can also vary by state and country.

How a letter of intent differs:

  • Informal, flexible, and can be handwritten or typed

  • Can be updated any time without involving an attorney

  • Should never contradict a formal will or trust - if a conflict exists, the legally binding documents control

Example: A Georgia will signed in 2026 controls the distribution of a home and investment accounts. A separate 2026 letter of intent explains why one child was chosen as trustee, outlines values for charitable giving, and lists specific instructions for distributing family heirlooms. Both documents work together, but each has a distinct role.

It helps to think of your advanced estate planning strategies as the architecture and your letter of intent as the user manual.

In Estate of Berger (California, 2023), a letter without proper formalities was admitted by the court as a will because circumstances demonstrated testamentary intent. This case underscores why your letter of intent should include a clear disclaimer stating it is not intended as a legal document.

What to include in a letter of intent for your loved ones

This is the heart of the document. A letter of intent can include logistical information, vital contacts, and personal wishes that provide guidance your legal documents leave out.

  • Personal message: Start with gratitude, encouragement, and a statement of faith or values. For clients who integrate biblical wisdom into their financial life, this is where stewardship principles and hope for future generations come alive.

  • Plain-English overview of your estate plan: Identify who the executor is, what trusts exist, and state overarching priorities (for example, "keep the family home until the youngest child finishes college").

  • Key contacts: Estate planning attorney, CPA, financial advisor, insurance agent, and corporate trustees. Include names, phone numbers, and roles.

  • Everyday practical details: Location of legal documents, password storage method (not the passwords themselves), safe deposit box location, keys, and alarm codes.

  • Tone: Warm but direct, making it easy for loved ones to act during a challenging time without guilt or second-guessing.

Personal wishes can include specific instructions for beneficiaries - from education priorities to career paths you hope a child or one of your heirs will explore. The letter provides a broad range of guidance that legal documents simply cannot capture.

Using letters of intent to direct personal belongings and heirlooms

Wills frequently describe only major assets and property, leaving room for conflict over personal belongings that carry sentimental weight but modest financial value.

  • Be specific: List items and intended recipients clearly. For example, "gold wedding band to my granddaughter Emma, born May 14, 2010." Vague references create disputes; precise details prevent them.

  • Group low-value items: Kitchenware, family Christmas ornaments, or photograph albums can be grouped with a clarifying note about rotation or selection among children.

  • Tell the story: Adding brief history behind important family heirlooms reinforces values across generations - not just distribution mechanics. A Bible that belonged to a great-grandmother means more when the family understands its provenance.

  • Coordinate with your attorney: If the distribution of a valuable collection - a classic car, coin collection, or art - could trigger disputes, align the letter with your will or trust structure so nothing contradicts the legal document.

Letters of intent help prevent disputes over personal belongings by making your intended wishes unmistakably clear.

Capturing financial, digital, and "nuts-and-bolts" details

Organized financial information can save an executor months of detective work. A letter of intent can clarify financial details for executors by creating a single reference point.

  • Financial assets to summarize: Main bank and investment firms, retirement accounts, annuities, life insurance policies, business interests, and any private loans owed to or by you. Financial details in a letter of intent include debts and investments - anything that affects the estate's bottom line.

  • Separate schedule: Specific account numbers and current values are often better kept in a regularly updated schedule stored with the letter, clearly dated (for example, "Asset list updated March 1, 2026"). Regular updates to financial details are essential for clarity.

  • Recurring bills and subscriptions: Mortgage, utilities, storage units, club memberships, digital services, and instructions for handling automatic payments.

  • Digital assets: Email accounts, social media profiles, personal websites, cloud storage. Describe whether accounts should be memorialized, closed, or archived.

  • Password security: Never put passwords directly in the letter. Instead, direct loved ones to a password manager or a sealed document kept in a safe or bank box.

Detailed financial records help executors manage assets effectively and avoid costly delays. If you've recently come into sudden wealth through an inheritance or business exit, this section of your letter becomes especially important - review our guide on investing an inheritance wisely for context on how these assets fit into your broader plan.

Special instructions for dependents, pets, and vulnerable beneficiaries

Some family situations demand extra care in your letter of intent, and this section can make an enormous difference for trustees and guardians.

  • Special needs dependents: A letter of intent can guide care for special needs beneficiaries by detailing daily routines, therapies, dietary needs, medical providers, and preferred living arrangements. Special needs beneficiaries may require specific medical and routine instructions that no legal document captures. Special-needs trusts can protect assets for beneficiaries with disabilities, and the letter adds the human context those trusts need.

  • Minor children: Include education priorities, church involvement, extracurriculars, and the values you hope guardians will emphasize - from spiritual formation to community service.

  • Pets: Name, breed, birth date (for example, "Lucy, golden retriever, born June 2020"), vet contact, feeding routines, and the person you hope will provide care.

  • Beneficiaries with money-management challenges: If a child or heirs struggles with addictions, creditor issues, or spending habits, frame guidance to trustees on how cautiously to use discretionary distributions.

Consulting an attorney is crucial for special needs estate planning. Estate plans should include provisions for beneficiaries with unique needs, and we recommend involving both your estate attorney and Third Act Retirement Planning when drafting these sensitive sections.

Funeral wishes, hospitality, and faith-driven legacy

Funeral wishes can be included in a letter of intent, and doing so spares your family from making painful decisions during grief.

  • Burial or cremation: A letter of intent can specify burial or cremation preferences, desired cemetery or location, type of service (church, graveside, or both), music, Scripture passages, and officiant preferences.

  • Obituary and memorial: Include obituary details, memorial donations in lieu of flowers, and whether you prefer a modest service or a larger celebration of life.

  • Faith and testimony: Clients of faith may want to include a life verse, testimony, or explanation of how biblical principles shaped their financial and estate decisions - putting a legacy of stewardship into words for future generations to reflect on.

  • Hospitality: Consider whether you want the estate to cover travel or lodging so out-of-town family members and communities of friends can attend the service.

Funeral wishes help guide loved ones during a challenging time and including them can prevent family disputes over arrangements. While funeral homes and advance directives also record some of these choices, the letter of intent is often the document grieving family members actually read first.

How to write a clear, effective letter of intent

Writing a letter of intent does not require legal expertise - it requires honesty and a little structure.

  • Use first person: Write as yourself. Phrases like "I would like…" and "My wish is…" convey intent without mimicking legal language. Avoid words like "bequeath" or "I direct," which could cause a court to treat the letter as a legal instrument.

  • Follow a simple structure: Opening message → overview of the estate plan → instructions by topic (personal property, finances, dependents, funeral) → closing blessing or encouragement.

  • Stay concise: A letter that runs dozens of pages can overwhelm an executor during a crisis. Cover each topic completely but efficiently.

  • Date every version: Label clearly, for example, "Letter of Intent – Revised October 15, 2026." Destroy outdated versions to prevent confusion.

  • Include a disclaimer: A short statement such as "This letter is not a legal document and does not override my will or trust" protects everyone.

Draft a rough version on your own, then refine it in conversation with your estate planning attorney and a financial planner at Third Act Retirement Planning.

Keeping your letter of intent aligned, updated, and accessible

A letter of intent loses its value - and can cause harm - if it falls out of date or contradicts your other estate planning documents.

  • Consistency is essential: If a conflict exists between the letter and your will or trust, the legally binding documents control, and the contradiction may spark disputes. Always cross-check.

  • Review schedule: Updating a letter of intent is essential after major life events such as marriage, divorce, birth of a child or grandchild, death of a named person, business sale, or large inheritance. Even without a triggering event, review every three to five years and after changes in tax laws.

  • Secure storage: Store the letter with other estate planning documents - in a labeled estate binder, a home safe, or a bank safe deposit box. It is essential to store the letter of intent securely and inform relevant parties and trusted individuals about its location.

  • Share strategically: Let your executor, successor trustee, selected trusted individuals, and possibly adult children know the letter exists and where to find it. Sharing the general content in advance reduces surprises.

  • Professional coordination: Third Act Retirement Planning can coordinate periodic estate plan reviews - including letters of intent - as part of ongoing wealth management for clients in and approaching retirement.

Next steps: integrating a letter of intent into your broader estate plan

A letter of intent is the human layer on top of your legal documents. It translates an estate plan into practical, personal guidance for the people who matter most. Without it, even the most carefully drafted trust can leave your family guessing about your intent, your values, and the everyday details that keep life running.

  • Confirm your foundation: Make sure you have core legally binding documents in place - a will, trust, powers of attorney, and current beneficiary designations - before relying on a letter of intent alone. If you're new to estate planning for significant wealth, start there.

  • Take three simple steps: Schedule a discovery call with Third Act Retirement Planning, coordinate with an estate planning attorney, and draft or update a personalized letter of intent.

  • Act on urgency if wealth is new: For individuals navigating sudden wealth - from inheritances to business exits or legal settlements - a letter of intent helps turn new assets into a purposeful legacy before the complexity of that wealth outpaces your planning. Avoid the common pitfalls of sudden wealth by documenting your intentions early.

Your estate plan protects your family's financial future. Your letter of intent protects something just as important - their peace of mind, their sense of your values, and the knowledge that you cared enough to leave a clear map rather than a confusing mess. That kind of stewardship is a gift no government form or legal filing can deliver on its own.
