Court of the Lord Lyon
The Court of the Lord Lyon, also known as the Lyon Court or Lyon Office, is a standing court of law which regulates heraldry in Scotland. Like the College of Arms in England it maintains the register of grants of arms, known as the Public Register of All Arms and Bearings in Scotland, as well as records of genealogies.
The Lyon Court is a public body, and the fees for grants of arms are paid to HM Treasury. It is headed by the Lord Lyon King of Arms, who must be legally qualified, as he has criminal jurisdiction in heraldic matters, and the court is fully integrated into the Scottish legal system, including having a dedicated prosecutor, known in Scotland as a Procurator Fiscal.
