Definition of Deraign

Seems to mean, literally, to cohfound and disorder or to turn out of course or displace; as deraignment or departure out of religion, in St. 31 Hen. VIII. c. 6. In the common law, the word is used generally in the sense of to prove; vis., to deraign a right, deraign the warranty, etc. Glanv. lib. 2, c. 6; Fitzh. Nat. Brev. 146. Perhaps this word "deraign," and the word "deraignment," derived from it, may be used in the sense of to prove and a proving, by disproving of what is asserted in opposition to truth and fact. Jacob.
