Chartered Surveyor is the description (protected by law in many countries) of Professional Members and Fellows of the RICS entitled to use the designation (and a number of variations such as "Chartered Building Surveyor" or "Chartered Quantity Surveyor" or "Chartered Civil Engineering Surveyor" depending on their field of expertise) in Commonwealth countries and Ireland. Chartered originates from the Royal Charter granted to the world's first professional body of surveyors. Chartered Surveyors are entitled to use "MRICS" after their names.
