In the case of a divorce from her husband Prince William, the Duchess of Cambridge, Kate Middleton, would be in the same position as her late mother-in-law, Princess Diana, and the ex-wife of Prince Andrew, Sarah Ferguson, in keeping from her royal title.
Although there is no speculation that the three-year-old parents are on their way to divorce, there are certain rules drawn up by Queen Elizabeth herself who would change the title of Middleton to the chance that she and her husband ever split up.
Daily Express reported that although the royal titles are an outdated formality, they are used as a way to distinguish nobility between family members.
Therefore, if Kate Middleton comes under the unfortunate circumstance to have to divorce the father of her three children Prince George, Princess Charlotte and Prince Louis, her title would automatically change. Middleton would be called Catherine, Duchess of Cambridge, instead of her current title of Her Royal Highness, the Duchess of Cambridge.
Daily Express noted that Lady Diana Spencer at her wedding with Prince Charles in 1981 automatically received the royal title of Her Royal Highness, the Princess of Wales. After the divorce of Diana from Prince Charles in 1996, Queen Elizabeth changed the law regarding titles within the royal family. She decided that women who marry the royal family would lose their HRH title in divorce.
Her official royal title was one thing that Princess Diana fought to keep when her divorce with Prince Charles was in the final phase.
However, The Daily Mirror reported that Princess Diana had lost her title of Her Royal Highness and instead became known as Diana, Princess of Wales. The deceased princess instead received a £ 17 million lump sum payment from the royal family (equivalent to more than $ 21 million in US currency) as part of her divorce from Prince Charles and £ 350,000 a year ($ 441,000) to run her private office .
She was able to keep her apartments in Kensington Palace and was allowed to share the custody of the sons William and Harry with Prince Charles.
Sarah Ferguson was also stripped of her title when she divorced Prince Andrew, Prince Charles’s brother. Ferguson received the title of Her Royal Highness, the Duchess of York when he married the royal family and after the divorce of the couple Sarah, the Duchess of York.
Daily Express also noted another circumstance that could happen to the royal couple, albeit an unfortunate one. If Prince William were to die before receiving the title of King of England, Middleton would remain HRH, the Duchess of Cambridge. But if they climb to the throne together, Middleton would be known as Dowager Queen.
In any case, the couple seems to be pretty happy raising their young family and immersing themselves in charity work, including their Heads Together campaign to shed light on mental illnesses and other charities that benefit children and families.
