Queen Elizabeth II’s death will herald a new era for the British monarchy. Not only will this automatically make Prince Charles the new king of England; it will also bring new changes into the lives of Prince William and Kate Middleton.

Now that Queen Elizabeth is already in her nineties, death already seems like a safe alley for her mind to wander into. In fact, she has put a lot of thought into what will happen to the rest of the royal family when she dies, instituting rules that her family members, the BBC and the public need to follow. Her death will be a turning point for all the rest of the royal family, including Prince William and Kate.

Once Queen Elizabeth dies, Prince William will not yet be king. However, he will get one step closer to being one. On the death of the Queen, the line of succession will change as Prince Charles ascends the throne. As Prince Charles becomes king, Prince William will then become the first in line to the throne.

The coronation of Prince Charles will automatically result in a title change for Prince William and his wife, Kate, as they inherit the current title of Prince Charles and Camilla Parker Bowles. From being the Duke and Duchess of Cambridge, they will become the new Duke and Duchess of Cornwall. Their new titles will also mean that they would have to take over the Duchy of Cornwall, a vast portfolio of properties that fund all the activities of the Duke of Cornwall and his family.

It is also likely for Prince William to become the new Prince of Wales when his father becomes king. This title is something that Prince Charles has held for decades, and he has the power to bestow it on his son when his time to reign comes.

It can be recalled that when Prince Charles married Diana Spencer, she was given the title Princess of Wales. If Prince Charles bestows his title on Prince William, then Kate will have the privilege to adopt the title of her late mother-in-law and become the new Princess of Wales.

As Prince William and Kate change their titles, they will need to make Kensington Palace their permanent residence. Currently, the royal couple and their children live in Anmer Hall in Norfolk and only visit Kensington Palace when their schedules permit. When Prince William becomes the first in line to the throne, however, he and his family will have Kensington Palace as their homebase as they fulfill their new royal duties.
