Untransfiguration is covered in beginner-level spellbooks such as A Beginner's Guide to Transfiguration. Learning untransfiguration is mandatory at Hogwarts School of Witchcraft and Wizardry from 1926 onward. Failure to at least attempt to untransfigure a wrongly-done transfiguration is considered irresponsible.
Reparifarge seems to be a general Untransfigurative spell used to counter the effects of a Transformation spell that was poorly performed and only partially transfigured the object in question. The spell is located in A Beginner's Guide to Transfiguration by Emeric Switch.
Vipera Evanesca is also a Untransfiguration spell. The incantation for the spell that causes a target Snake to vanish in a puff of black smoke. As such, it can be used as a counter-spell for spells that produce serpents, such as Serpensortia or the Fire to snake spell, annihilating the conjured or transfigured snake.
Revelio could be used to untransfigure a human transfiguration.
Known instances of Untransfiguraton
In the aftermath of the arrest of Percival Graves, Newton Scamander used a Revelio Charm to reveal that it was actually the Dark Wizard Gellert Grindelwald, who had used Human Transfiguration to take the appearance of the MACUSA official.
Behind the scenes
According to W.O.M.B.A.T., it may not be possible to Untransfigure a person or object without knowing what they were originally. However, in Harry Potter and the Goblet of Fire, when Draco Malfoy is turned into a ferret, Professor McGonagall Untransfigures him while only knowing that it was a student, not who it was specifically. This implies that either one does not need to know very specific details about what the object was before Transfiguration or that she guessed it was Malfoy due to his absence from his usual gang.
