James Williams, 1911 Encyclopædia Britannica, Volume 28… (1911)
“ Scotland.—The term corresponding to warranty in the law of heritable property is “warrandice.” Warranty, strictly speaking, seems confined to movables. Warrandice appears early in Scots law, the heir by Regiam Majestatem being bound to warrant the reasonable donations of his ancestor. Warrandice in the existing law is either real or personal. Real warrandice is that whereby warrandice lands are made over, as indemnity for those conveyed, to assure the person to whom they were conveyed from loss by the appearance of a superior title. Real warrandice is implied in excambion. ”
