Current Titles of William and Catherine
Prince William holds the title of Prince of Wales, a title traditionally granted to the heir apparent to the British throne. Catherine holds the title of Princess of Wales as the wife of the Prince of Wales. The couple are not King and Queen; that title belongs to King Charles III and Queen Camilla following the passing of Queen Elizabeth II. As the eldest son of King Charles III, William is first in line to the throne, making him the Duke of Cornwall and Duke of Rothesay in addition to his Prince of Wales title source.
The title of King is held by the reigning monarch, currently King Charles III, who acceded to the throne on September 8, 2022. Queen consort is the title for the wife of a reigning king, which is currently held by Queen Camilla. William and Catherine are therefore the Prince and Princess of Wales, not the King and Queen. Their future titles will change only if and when William becomes King source.
Succession and Future Roles
Under the current line of succession, William is the first in line to become King, followed by his eldest son, Prince George. The Succession to the Crown Act 2013 ended male primogeniture, meaning the eldest child inherits regardless of gender. Catherine will automatically become Queen consort when William ascends the throne, a role that is ceremonial and supportive rather than sovereign source.
The coronation of King Charles III took place on May 6, 2023, at Westminster Abbey. The coronation formalized the roles of the new monarch and the queen consort. William and Catherine continue to carry out public duties on behalf of the King, focusing on areas such as mental health, early childhood development, and environmental causes. Their public engagements are part of the working responsibilities of the senior royals source.
Financial and Institutional Context
The British monarchy operates as a constitutional monarchy, with the sovereign serving as the head of state. The Crown Estate is a collection of lands and holdings that belong to the reigning monarch in a corporate capacity. The Duchy of Lancaster and the Duchy of Cornwall are separate estates that provide income to the sovereign and the Prince of Wales respectively. William, as Duke of Cornwall, benefits from the Duchy of Cornwall, a portfolio of land and investments source.
The Sovereign Grant is the annual payment from the UK government to the monarch, calculated as a percentage of the Crown Estate profits. The financial structure of the monarchy is regulated and reported, with the Keeper of the Privy Purse overseeing the King's private finances. As heir apparent, William does not receive the Sovereign Grant but manages his own public and charitable funding through the Prince of Wales's Charitable Fund and other entities source.
