A Coat of Arms is a design which identifies a specific person, family or organisation. In Scotland, Coats of Arms can only belong to one person at a time.
The Public Register of All Arms and Bearings in Scotland records every Coat of Arms in Scotland since 1672, and is updated every day.
If you want to search the Public Register for a certain Coat of Arms, it's open to personal inspection in the Court of Lord Lyon in Edinburgh.
Visit the Court of Lord Lyon website for information on searching the Public Register, including fees and opening times.
