The office of Lord Clerk Register is the oldest surviving Great Officer of State in Scotland, with origins in the 13th century. It historically had important functions in relation to the maintenance and care of the public records of Scotland. Today these duties are administered by the Keeper of the National Records of Scotland and the Keeper of the Registers of Scotland. History of Office Kingdom of Scotland The first usage of the office appears in 1288, as Clerk of the Rolls of the Kings Chapel. It later was termed in 1291 as 'Keeper of the Rolls of the Kingdom of Scotland' After the Wars of Independence, a similar office appeared with the title of 'Clerk of the Rolls', which was altered about 1373 to 'Clerk of the Rolls and Register', the 'register' being the record of charters (ie: grants of land or titles of nobility) made under the Great Seal. While the Clerk of Rolls and Register was originally responsible for the records of Chancery, Parliament and Exchequer, but as the central civil court developed out of the king's council in the fifteenth century, he became responsible for its records too, and from 1483 he was 'Clerk of the Rolls, Register and Council'5. This court later became the Court of Session. By the fifteenth century, the Clerk Register ranked as an officer of state with a seat in Parliament and the council. By the sixteenth and seventeenth centuries more honorific styles such as 'Lord Register' or 'Lord Clerk Register' came to be adopted when describing the Clerk of Rolls. The Clerk Register remained responsible for the records of Parliament and its committees and commissions, the Exchequer, and the Court of Session (representing the judicial side of the old council). From the later sixteenth century statutory additions were made to his functions as new legal registers were put under his control, the most important being the Register of Sasines in 1617 with the passage of the Registration Act 1617. By the time of the Union with the Kingdom of England in 1707, the office was known as the 'Clerk of the Registers and Rolls of the council, Session and Exchequer, and of all Commissions, Parliaments and Conventions of Estates'. Since 1488 appointments to the office have been made by the Sovereign by commission under the Great Seal. Kingdom of Great Britain The Treaty of Union in 1707 provided for the
