Duchess Catherine is currently the Duchess of Cambridge, but she will receive a new title when her father-in-law, Prince Charles, takes the throne.
What title will Duchess Catherine have when Prince Charles is King?
When Charles ascends the throne, Kate and William’s titles are expected to undergo a major change, as they will no longer be Duke and Duchess of Cambridge.
As male heir to the throne, Prince Charles is the current holder of the traditional title Prince of Wales.
When Prince Charles becomes King, it is expected that Prince William will become the Prince of Wales, as he will then be heir apparent.
This means that Kate would become the Princess of Wales and would likely be known as Catherine, Princess of Wales.
This would be the same title Duchess Catherine’s late mother-in-law, Princess Diana, received when she married Prince Charles in 1981 – she was styled as Diana, Princess of Wales.
Prince Charles is the longest-serving Prince of Wales in history, having first acquired the title in 1958.
The traditional title was first used by an English heir to the throne back in the 14th Century.
However, the title is not automatically given to male heirs.
As the Constitution Unit at University College London (UCL) explain: “Charles was created Prince of Wales in 1958 when he was aged 10, with an investiture at Caernarvon Castle in 1969.
“As an adult, Prince William might expect to become Prince of Wales soon after his father’s accession; but that will be a matter for the new King to decide because, strictly, the title is not heritable.”
