The proprietary right to an estate in fee simple was determined by the writ of right often referred to as the grand assize, from the method of trial granted by Henry II, in actions of this character. There were four forms of writs of right proper: (a) the writ or right patent; (b) the writ of right quia dominus remisit curiam' (c) the writ of right precipe in capite, and (d) the writ of right patent in London.
