Not sure about a link, but the basic problem is that "legal description" simply doesn't make sense. Instead, we actually write "property descriptions". Then these descriptions may be included in legal documents. But there is nothing "legal" about a property description that is not part of some other document.
But having said that, you can go anywhere in the US and say "I need a legal description" and people will know exactly what you mean. Even in our company, we still say "we need to prepare a Legal for that job", and stuff like that. But when I actually create documents for recording, I usually put "Property Description" in the document, not "Legal Description".
It's one of those things that gets mis-used so often that the mis-use has become "normal", even though it doesn't really make sense. Kind of like people who say "I could care less". You mean you could care less, but you choose not to?
