Emotional support animals

[Robert Freeborn]

A friend of mine living in Utah is trying to get an emotional support animal, but her landlord is having issues. Besides being provided with letters from her doctor and psychologist for the need for the animal, he is demanding to speak with the doctors. (Which is totally illegal, right?) My friend also claims that an ESA doesn’t need to be certified, just needs to have a letter from her doctor. I’ve looked, but can’t find any evidence supporting that. Can anyone here point me to a source that says if she does or doesn’t need the animal certified?
