The Letter of Intent: The Most Important Document No Attorney Drafts

Key Takeaways

Parents of children with disabilities spend years — decades — learning everything about their child. They know which foods cause a reaction, which sounds trigger anxiety, which therapist works and which does not, what time the routine must start in the morning, and exactly how to phrase a request so their child understands and cooperates. This knowledge is encyclopedic, deeply specific, and entirely undocumented.

When those parents die or become incapacitated, that knowledge dies with them. The successor trustee has a trust document that explains how to manage money. The successor guardian has a court order that grants legal authority. But neither document tells anyone what the person eats for breakfast, how they communicate pain, why Tuesdays are difficult, or that they need their blue blanket to sleep. The letter of intent is the document that carries this knowledge forward.

What a Letter of Intent Is

A letter of intent is a written document — prepared by the parents or primary caregivers — that provides comprehensive information about a person with a disability. It is addressed to the people who will be responsible for the person's care and well-being after the parents are no longer able to fill that role: the successor guardian, the trustee of the special needs trust, the residential care provider, the sibling who will oversee care, or any other person who will be involved in the person's life.

The letter of intent is not a legal document. It is not drafted by an attorney. It is not filed with any court. It is not legally binding on anyone. And yet, for the practical purpose of ensuring continuity of care, it may be the most important document in the entire special needs estate plan.

Why Attorneys Do Not Draft It

Attorneys draft legal documents: trusts, wills, powers of attorney, guardianship petitions. These documents define legal relationships, control assets, and grant authority. They are essential. But they do not — and cannot — capture the lived experience of caring for a specific person with a specific disability.

A trust document can authorize the trustee to pay for therapies. It cannot explain which therapist has the best rapport, which therapy modality works and which one the person resists, or that the person needs to arrive 10 minutes early and sit in the same chair every session. That information exists only in the minds of the parents who have spent years learning it through daily experience. The letter of intent is the mechanism for transferring that knowledge.

What to Include

Personal history and family background. Birth date, diagnosis history, developmental milestones, family relationships, and a narrative of the person's life that gives the reader context for everything that follows.

Daily routines and schedules. Morning routine (step by step), mealtime preferences, afternoon activities, evening routine, bedtime ritual. The level of detail matters: "needs to brush teeth before getting dressed" or "will not eat if the food touches other food on the plate."

Medical information. Current diagnoses, medications (names, dosages, schedules, side effects to watch for), allergies, medical providers (names, addresses, phone numbers), insurance information, and a history of hospitalizations or medical events.

Behavioral patterns. What causes anxiety, what calms them, what triggers a meltdown, how to de-escalate, what environments they thrive in, what environments they cannot tolerate, and how they express distress, pain, happiness, and frustration.

Communication. How the person communicates (verbal, sign language, communication device, gestures), how to interpret their communication, and how to communicate with them effectively.

Social and recreational life. Friends, social groups, recreational activities, religious or spiritual practices, hobbies, and preferred entertainment. These elements define quality of life and should not be lost in a transition.

Housing preferences. Where the person currently lives, what type of living arrangement works best, what the parents' vision is for future housing, and any specific requirements (proximity to family, accessibility features, noise sensitivity).

The parents' vision. What the parents want their child's life to look like. Not in legal terms, but in human terms. What matters most to them. What they hope for. What they fear. This section gives the future caregivers and trustees a moral compass to guide decisions that no legal document can anticipate.

Who Should Receive the Letter

The letter of intent should be shared with every person who will play a role in the disabled person's life after the parents are gone. This includes the successor trustee (who needs to understand what trust expenditures will best serve the beneficiary), the successor guardian (who needs to understand daily care), siblings who will be involved in oversight, residential care providers, and any advocacy organizations involved in the person's care.

Copies should be kept with the estate planning documents, with the trustee, and with the successor guardian. A digital copy should be stored where it can be accessed quickly in an emergency.

Keeping It Current

A letter of intent is a living document. It must be updated as the person's needs, preferences, and circumstances change. Medications change. Therapists change. Routines evolve. New challenges emerge. A letter written when the person was 15 will be inadequate when they are 30.

The best practice is to review the letter annually — on the person's birthday, for example — and update it whenever there is a significant life change. The letter should include a date on every page so that readers can assess how current the information is.

The Bottom Line

The special needs trust controls the money. The guardianship controls the legal authority. The letter of intent controls the quality of life. Without it, even the best-funded trust and the most devoted guardian are working blind — making decisions about a person's daily existence without the information they need to make those decisions well.

No attorney will draft it. No law requires it. But for the person with a disability whose entire world depends on the people who understand them, the letter of intent is the document that matters most.

A non-legal document written by parents that provides detailed information about a disabled person's routines, medical needs, preferences, and care instructions for future caregivers, trustees, and guardians.

Personal history, daily routines, medical information, medications, behavioral patterns, communication methods, social relationships, housing preferences, and the parents' vision for their child's future quality of life.
