Writing a Letter of Intent for Your Child's Future

9 min read · Updated August 13, 2026

The short answer

A letter of intent is a non-binding document describing how to care for your child: the daily routine, food, communication, what calms and what escalates, sleep, medical details, providers, the people who matter, and what you hope for. It has no legal force, so write it plainly and date every version.

A letter of intent is the document that carries everything the legal paperwork cannot. A will says who inherits. A trust says how money is managed. A guardianship names who decides. None of them say that your son will not sleep without the blue blanket, that he shuts down in fluorescent light, or that the word "later" means something specific in your house and using it wrong costs an hour.

The letter of intent holds that. It has no legal force, and that is the point. It is not competing with the attorney's documents, so it can be long, plain, personal, and updated whenever something changes. Families who have one describe it as the single most useful thing they wrote. Families who need one and do not have it are usually reconstructing it from memory under bad conditions.

Who actually reads it, and when

Picture the realistic scenarios rather than the worst one. A grandparent taking over for two weeks while you are in the hospital. A sibling stepping in decades from now. A trustee deciding whether a request is reasonable. A new caregiver on their first morning.

None of them will read a fifty-page document cover to cover on the day they need it. Write so the first two pages are enough to get through a day, and the rest is there when there is time.

Start with the day

Not the diagnosis. The day. This is the section people skip and the section that gets used first.

  • Morning, in order. What time, what wakes them, what happens first, what cannot happen first.
  • Food. What they eat, what they will not, textures that are a problem, how food is presented, allergies and the difference between an allergy and a refusal.
  • Communication. How they tell you they are hurting, hungry, overwhelmed, or done. Include the signs that are easy to misread as behaviour.
  • Regulation. What calms them and what escalates. Be specific. "Music helps" is not usable. "The same album, low, from the kitchen speaker, not headphones" is.
  • Sleep. The routine, the objects, what happens if it is interrupted.
  • Bathroom and hygiene, in whatever detail is real, written plainly. Nobody reading this is embarrassed.

Then the picture around the day

Medical: diagnoses, medications with doses and what each is for, allergies, every doctor and specialist with a phone number, the pharmacy, the equipment and who services it, and what a bad day looks like versus an emergency.

Education and services: current school and program, the case manager, what the IEP promises and what is actually delivered, the therapies and who delivers them, what has worked, and what was tried and failed. The failures save the next person a year.

The people: who knows your child well, who is safe, who is not, siblings and what each relationship is like, and the friends or staff who matter.

Say what you want, plainly

This is the part only you can write, and it is the part families say they most wish they had.

Where should your child live, and what would make that decision change. What does a good week look like. What work or activity matters to them. What are your hopes, in ordinary words. What would you not want, and why. Religion, traditions, and the things that would feel like a loss if they quietly stopped happening.

Write it the way you would say it out loud to someone you trust. Formality helps nobody here.

Where it fits with the legal documents

The letter of intent sits alongside the rest of getting your affairs in order, never inside it. It has no binding force, cannot direct money, and cannot appoint anyone.

The instruments that do carry legal weight are a different conversation with an attorney who works in this area, and the choices there can affect benefit eligibility in ways that are easy to get wrong. That is worth paid advice.

What the letter does is make those instruments usable. A trustee holding money and no context makes worse decisions than a trustee holding the same money and forty pages describing the person it is for.

Make it a document that survives you being busy

The most common failure is not a bad letter. It is a good letter written once, in a burst, and never touched again, describing a child who has since changed schools twice.

Date every version. Put the date on the first page where a reader will see it. Pick one time a year that already exists in your calendar, such as the week after the annual school meeting, and re-read it then. Most years you will change three lines.

Then tell people it exists and where it is. A letter nobody can find on the day they need it did not get written.

A letter of intent carries everything the legal documents cannot: the routine, the communication, the people, and what you actually want for your child. It has no legal force, which is exactly what lets it be personal and current. Write the day first, date it, and tell someone where it lives.

Common questions

Is a letter of intent legally binding?

No. It carries no legal force and cannot direct money or appoint anyone. That is why it can be personal, detailed, and updated freely. It works alongside the legal documents rather than replacing any of them.

How long should a letter of intent be?

Long enough to be useful, which for most families is somewhere between ten and forty pages over time. Structure matters more than length. Put the daily routine and the emergency information first so the first two pages are enough to get someone through a day.

How often should I update it?

Once a year is enough for most families, plus a quick pass after anything significant changes, such as a new school, a new medication, or a new provider. Date every version on the first page, because an old letter is easy to mistake for a current one.
