An intervention letter is a short, loving message, about one page, that each person reads aloud during an intervention. A strong letter has four parts: what you love about the person, specific moments you have seen, how those moments have affected you, and a clear ask to accept help today. It avoids blame, labels and old arguments.

What is an intervention letter for?
A letter keeps you steady when emotions run high. Reading from a page stops the conversation from turning into an argument, keeps each person to the point, and lets your loved one hear, in your own words, how much you care and what you have seen. Many families say writing the letter was the moment they finally put months or years of worry into words.
Letters fit some intervention approaches better than others. In a structured intervention each person usually reads a letter. In invitational and family systems approaches, letters may be shared differently or used mainly to help the family prepare. Our team helps decide what fits your family; compare approaches in intervention methods compared.
What are the four parts of an intervention letter?
| Part | What to write | Example line |
|---|---|---|
| 1. Love and connection | Open with a real memory or quality you admire, so they hear love first. | “I still think about the summer you taught your little sister to swim.” |
| 2. What you have seen | Two or three specific, recent moments, described calmly. Facts, not labels. | “On March 3rd you missed Sam’s birthday dinner, and when you arrived you could not stand up.” |
| 3. How it affects you | “I” statements about your own feelings: worry, fear, sadness. Not accusations. | “I lie awake waiting for a call that something has happened to you.” |
| 4. The ask | One clear request: accept the help that is ready today. | “There is a place ready for you this afternoon. Will you accept this help today?” |
How long should an intervention letter be?
Keep it to one page, or about two to three minutes read aloud at a calm pace. Several people may read, and a long letter loses its force. If you have more to say, choose the moments that matter most and save the rest for family therapy later.
What should you leave out of an intervention letter?
- Labels such as “addict”, “alcoholic”, “liar” or “selfish”. Describe what happened instead.
- Old arguments and lists of every wrong. Pick a few recent, specific moments.
- Threats. Boundaries belong in a separate, calm statement that is only read if needed (see the boundary template below).
- Diagnoses or guesses about mental health. Leave assessment to professionals.
- Surprises for the rest of the team. Share your letter with the group, or with your interventionist, before the day.
- “Always” and “never”. They invite an argument about the exception.
Free intervention letter templates
Copy a template, then replace everything in [brackets] with your own words. The best letters sound like the person reading them, so change anything that does not sound like you.
Template 1: Parent to an adult son or daughter
Template 2: Husband or wife to a spouse
Template 3: Adult child to a parent
Template 4: Brother or sister
Template 5: Friend
Template 6: Parent to a teenager (13 to 17)
With teenagers, parents usually make the decision about care, so the tone is less about asking for a yes and more about explaining, calmly, what is happening and why. Read more in intervention for a teenager.
Boundary statement (read only if the answer is no)
A boundary is what you will do, not what you will make your loved one do. Only write one you can keep for months. Read more in what if they say no.
How do you read the letter during the intervention?
- Agree on the order of readers in advance. Many families start with the person closest to your loved one, or the calmest voice.
- Read slowly. Pause if you need to. Tears are fine.
- Do not respond to interruptions or arguments. A professional or the lead family member can redirect.
- End every letter with the same ask, so the message is consistent.
Intervention letter questions
How long should an intervention letter be?
About one page, or two to three minutes read aloud. Several people may read, and shorter letters keep the conversation focused and calm.
What should you say in an intervention letter?
Start with love, describe two or three specific moments you have seen, say how they have affected you using “I” statements, and end with one clear ask to accept the help that is ready today.
Should the boundary go in the letter?
Usually not. Many families keep the boundary as a separate, short statement that is read only if the answer is no, so the letter itself stays focused on love and the ask.
Can a professional review our letters?
Yes. Reviewing letters is part of how our intervention team prepares families. Planning and family coaching can happen by video before the team travels, and your first call is free.
Do all interventions use letters?
No. Letters are central to structured interventions, while invitational and family systems approaches may use them differently. The right approach depends on your loved one and your family.
