Are online emotional support animal letters legal in Montana?
Montana
The delivery method was never the issue in Montana. The 30-day rule is.
The short answer
Online is not the problem in Montana. Speed is. Mont. Code Ann. § 70-24-114, enacted by HB 703 (2023) requires the client-provider relationship to predate the documentation by 30 days, and that applies whether the clinician is down the road or on a screen.
HB 703 took effect on 1 October 2023 and was tightened again by SB 149 in 2025. The provider must have been treating the person for at least thirty days before issuing the letter, and the document has to carry the licence type, number and effective date.
So a Montana letter bought online and delivered within the hour is not lawful documentation. It is not a grey area and it does not depend on how the letter is worded.
How to tell the difference
- Does it name a clinician, with a licence type, number and issuing state you can check against the board? A letter that does not is not going to survive scrutiny.
- Is the clinician licensed in Montana? A licence from elsewhere does not carry.
- Can the answer be no? A guarantee of approval is a guarantee that nobody is deciding.
- Is it selling a registration, certificate or ID alongside the letter? Those have no legal effect, and California requires sellers to say so in writing.
- Does the timeline actually allow 30 days? In Montana this is the question that decides it.
The Montana legal position
Montana has its own fair housing statute, the Montana Human Rights Act (Mont. Code Ann. § 49-2-305), enforced by the Montana Human Rights Bureau. A state complaint runs on state law, so HUD changing its own enforcement priorities does not decide it.
Montana also legislated on emotional support animals directly, which most states have not. These are the sections that matter:
- Mont. Code Ann. § 70-24-114: Enacted by HB 703 in 2023 and amended by SB 149 in 2025, this section sets out what a landlord may require for an assistance animal, what a provider must do before issuing documentation, and graduated penalties for fraudulent documentation.
What a housing provider will actually do
A Montana housing provider handed a letter has no register to check it against, which is the reason so much of this market is worthless paper. Every letter issued here carries a six digit ESA ID and a public verification page, so a landlord can confirm the letter is real, current, and issued by a licensed clinician without being shown a single word about anybody's health.
Common questions
- Are online ESA registrations valid in Montana?
- No, and not anywhere else either. There is no federal or state register of emotional support animals, so nothing can put you on one. California legislated specifically to require sellers of these products to disclose that in writing.
- Will a Montana landlord accept a telehealth letter?
- They are entitled to test it against Mont. Code Ann. § 70-24-114, enacted by HB 703 (2023). A telehealth letter from a relationship of at least 30 days with a Montana-licensed clinician is documentation. One issued the same day is not.
- What happens if a landlord decides my letter is fake?
- They can refuse the accommodation on reliability grounds, and you would be arguing about it afterwards rather than living with your animal in the meantime. This is the practical reason a verifiable letter is worth more than a cheap one.
