1911 Encyclopædia Britannica/Administrator (English law)
ADMINISTRATOR, the person to whom the Probate Division of the High Court of Justice (formerly the ordinary or judge of the ecclesiastical court) acting in the sovereign's name, commits the administration (q.v.) of the goods of a person deceased, in default of an executor. The origin of administrators is derived from the civil law. Their establishment in England is owing to a statute made in the 31st year of Edward I. (1303). Till then no office of this kind was known besides that of executor; in default of whom, the ordinary had the disposal of goods of persons intestate, &c. (See also Executors, and, for intestate estates, Intestacy.)
Administrator in Scots law, is a person legally empowered to act for another whom the law presumes incapable of acting for himself, as a father for a pupil child.
