Who Can Write an ESA Letter? Providers, Rules and Red Flags
- Published on:
- By: ASP Team
You’ve decided an emotional support animal (ESA) could help, and now you need a letter. The first question is who’s allowed to write it. Search for an answer and you’ll find three: only a therapist, any doctor, or anyone with a website. None of them is quite right.
A licensed healthcare or mental health professional can write an ESA letter if they’re licensed in your state, working within their scope of practice, and have evaluated you. Therapists, counselors, social workers, psychologists and psychiatrists do this most often. Primary care doctors and nurse practitioners sometimes can, depending on your state and whether they know your health history.
Key takeaways
- The provider has to be licensed in your state, working within their scope, and have evaluated you.
- Therapists, counselors, social workers, psychologists and psychiatrists are the most common writers.
- Primary care doctors, nurse practitioners and physician assistants (PAs) sometimes can. It depends on your state and on whether they know your situation.
- Registries, certificate sites, and life coaches cannot write a valid letter.
- You can check a provider’s license yourself in a few minutes.

What Any Provider Needs to Write an ESA Letter
Whatever their title, a provider needs four things before a letter holds up. A job title alone doesn’t make a letter valid.
- A license in your state. The provider’s license has to match where you live.
- A scope of practice that covers it. A license doesn’t cover everything. Whether a provider can assess this kind of need depends on their training and their state’s rules.
- A real evaluation. The provider has to assess you, not fill out a form.
- Personal knowledge of your situation. The provider needs to understand your circumstances firsthand, which an evaluation provides.
Some states add a waiting period. Arkansas, California, Iowa, Louisiana and Montana require a 30-day patient-provider relationship before a letter is provided. It’s more than a waiting period: the provider has to work with you during that time. In most of these states, the provider decides how many contacts are clinically appropriate, but Louisiana requires at least two sessions.
Which Providers Can Write an ESA Letter?
Mental health professionals are the most common and most straightforward choice. Doctors and nurse practitioners are a “sometimes.” Here’s the quick version, followed by what to know for each.
| Provider | Can they write one? | What to know |
|---|---|---|
| Therapist or counselor (LPC, LMHC, LMFT) | Yes | Best fit if they already know your history. Some decline by policy. |
| Licensed clinical social worker (LCSW) | Yes | Same strengths as a therapist. Many already work with you on daily functioning. |
| Psychologist (PhD, PsyD) | Yes | They diagnose and treat. Most don’t prescribe, and an ESA letter isn’t a prescription. |
| Psychiatrist (MD, DO) | Yes | Often the strongest fit when a condition is medically managed. |
| Primary care doctor | Sometimes | Depends on your state and whether they know your condition. Many refer you out. |
| Nurse practitioner or PA | Sometimes | Depends on state scope-of-practice rules. Psychiatric nurse practitioners are the likeliest. |
Can Your Therapist or Counselor Write an ESA Letter?
Yes, in most cases. If you already see one, they know your history, which helps with the personal-knowledge test. Some therapists decline as a matter of practice or employer policy, so ask before you assume.
Can an LCSW Write an ESA Letter?
Yes, for the same reasons. A licensed clinical social worker can evaluate how a condition affects your daily life, as long as they’re licensed in your state and the letter falls within their scope.
Can a Psychologist Write an ESA Letter?
Yes. Psychologists diagnose and treat mental health conditions. Most don’t prescribe medication, which doesn’t matter here, because an ESA letter isn’t a prescription.
Can Your Psychiatrist Write an ESA Letter?
Yes. A psychiatrist is often the strongest fit when your condition is already being managed medically. Some work inside health systems that restrict this kind of documentation, so you may get a referral instead.
Can Your Doctor (Primary Care Physician) Write an ESA Letter?
Sometimes. In many states a primary care doctor can write one if they know your condition and act within their scope. But many decline or refer you to a mental health professional, and some health systems have policies against it.

Can a Nurse Practitioner or PA Write an ESA Letter?
Sometimes. It depends on your state’s scope-of-practice rules and on whether the provider treats mental health. A psychiatric mental health nurse practitioner is the likeliest to say yes. PAs follow their state’s scope-of-practice rules, so ask what they’re authorized to do.
Who Can't Write a Valid ESA Letter
Several sources look official and aren’t. If any of these wrote your letter, a landlord has good reason to question it.
- Online registries and certificate sites
- AI tools and letter templates
- Life coaches, unlicensed counselors, friends and family
- Veterinarians
- A provider who isn’t licensed in your state
Can an Online Provider Write an ESA Letter?
In most states, yes, when the provider is licensed in your state and the evaluation is real. Telehealth is a normal way to be evaluated. A few states add requirements, such as an in-person meeting, so check your state’s rules or ask your provider.
In states with a 30-day requirement, the patient-provider relationship has to be established first, so an online service can’t skip that step.
American Service Pets is a platform that connects patients with licensed mental health professionals in the patient’s state. You complete a health assessment, and the provider decides whether to recommend an ESA and provide documentation.
Can BetterHelp or Other Therapy Apps Write an ESA Letter?
The answer depends on the platform and the therapist. A licensed therapist on a counseling app is still a licensed therapist, so the four things above apply. But some platforms set their own policies on assistance animal documentation, and not every therapist offers it.
The quickest way to find out is to ask your therapist directly and check the platform’s help pages. If they can’t or won’t, you can see a provider who does these evaluations. Our guide to where to get an emotional support animal evaluation covers your options.
What If Your Provider Says No?
Hearing no is frustrating, but it isn’t a judgment about you. It usually means they don’t write these letters, or they don’t know you well enough to.
Providers decline for a few common reasons:
- Their employer or network has a policy against it.
- ESA documentation falls outside what they do.
- They haven’t evaluated you for this yet.
You still have options. American Service Pets connects patients with licensed mental health professionals in their state, and the provider decides whether an ESA recommendation is clinically appropriate.
