AS the country mourns the death of Queen Elizabeth II, titles within the monarchy will change.
But what does that traditional structure look like and who is expected to be affected by it?
Who will change their title?
King Charles III
When his mother passes away, Prince Charles will inherit the throne to become king.
He is likely to be known as King Charles III but there is a chance he could opt to change his regnal name to something different.
It is expected that he will move into Buckingham Palace – and Prince William, who moved into Adelaide Cottage in June 2022, may move to Windsor Castle with wife Kate Middleton.
The Prince of Wales, 73, is said to be planning to move to the Palace when he takes the throne because he believes a "monarch should reside at a HQ".

He and wife Camilla Parker Bowles will reportedly be crowned alongside one another when the time comes – in a largely scaled-down coronation.
Plans are said to be being drawn up for the event using the codename Operation Golden Orb.
Camilla, Queen Consort
Throughout British history, the husband or wife of the monarch is known as the consort, a position that has no constitutional role but carries significant prestige.
A queen consort is the wife of a reigning king and usually shares her spouse's social rank and status.

The mother of Queen Elizabeth II served in this role while her husband, the Queen's father – King George VI – was on the throne from 1936 until 1952.
The assignment of the title Queen is reserved for those born into the monarchy.
Prince William, the Duke of Cambridge – Prince of Wales
As the oldest son of the monarch, Prince William will become the 27th Prince of Wales, the Duke of Cornwall and the Earl of Chester when his father is made king.
He will also likely take up the titles of Prince and Great Steward of Scotland, Earl of Carrick, Baron of Renfrew, Lord of the Isles and Duke of Rothesay.
Catherine, the Duchess of Cambridge – Princess of Wales
Once Prince Charles is made king, Kate Middleton will be made the Princess of Wales.
She will also step into Camilla's current title as the Duchess of Cornwall.
Kate is likely to also be named Countess of Chester, and will be named the female equivalent of her husband's new titles.
Prince George of Wales
Both Prince William and Prince Harry were known by this title before they married, as their father Charles was at that time the Prince of Wales.
Prince George is the eldest child of Kate and Prince William and will one day be king.
Princess Charlotte of Wales
Princess Charlotte will take the female equivalent of her brother's title as Princess Charlotte of Wales.
But William and Kate's only daughter could become the Princess Royal when her father becomes King.
The title is reserved for the monarch's eldest daughter and is currently held by Princess Anne.
Although Princess Charlotte is expected to be given the title, it's not an automatic right and it has to be bestowed by the reigning monarch.
Royal expert Duncan Larcombe told Town & Country: "It is a title that remains for life.
"Princess Charlotte will have to wait at least until the death of the current Princess Royal."
Prince Louis of Wales
Prince Louis Arthur Charles was born on April 23, 2018, at St Mary's Hospital in Paddington, London.
And just like his older brother, he was granted the title of His Royal Highness under letters patent issued by his great-grandmother.
The Succession to the Crown Act 2013 ruled means that Prince Louis will not jump over his older sister Charlotte in line to the throne.
Archie and Lilibet
The children of the Duke and Duchess of Sussex, Prince Harry and Meghan Markle, were not officially given titles at birth.
But when their grandfather takes the throne, a tradition introduced by King George V in 1917 may allow them to use their title.

He deemed the grandchildren of the monarch to be entitled to use prince or princess and HRH with the exception of the eldest son of the eldest son of the Prince of Wales.
This was changed by the Queen when she extended the titles to all of Prince William's children but Archie and Lilibet will still be entitled to the style of Prince and HRH when Charles inherits the throne.
