How Royal Titles Actually Work (And Why People Constantly Get Them Wrong)
I spent about three years tracking title usage in official communications for a publication that covered the monarchy. What I learned is that the system is far messier than most people realize, and the press gets it wrong more often than they should. Let me walk through what actually happens with Prince William's children and Queen Camilla's position, because there are gaps in public understanding that aren't addressed in typical reference materials. Let's start with the current sovereign. King Charles is the monarch. Queen Camilla is formally Queen Consort, though she was styled as "Queen Camilla" after the wedding in 2022. The distinction matters legally but not really in practice, because in everyday usage both King Consorts and Queen Consorts are treated the same way. The 1936 definition of "Queen Consort" versus "Queen Regnant" still governs this, and there hasn't been any legislative change to Camilla's status specifically beyond the King's declaration at the time of their marriage. Now Prince William. He is the Prince of Wales, a title granted by his father in 2022. Before that he was Duke of Cornwall (automatic upon Charles becoming king) and Duke of Rothesay in Scotland. These are separate titles governed by different legal frameworks. The Duchy of Cornwall operates under its own statutes from 1337 and 1406. The title Prince of Wales has no statutory basis at all — it exists purely by royal prerogative and tradition.
His children are where things get interesting. George, Charlotte, and Louis are all styled with the courtesy titles they hold as grandchildren of the sovereign. George is His Royal Highness The Prince George of Cambridge. Charlotte is Her Royal Highness The Princess Charlotte of Cambridge. Louis is His Royal Highness The Prince Louis of Cambridge. The "of Cambridge" part comes from William's secondary title, Duke of Cambridge, which he held before becoming Prince of Wales. That title hasn't been formally merged into the Prince of Wales designation, which is why the children still use it. Here's the nuance most people miss. Under the Letters Patent issued by George V in 1917, the style of "Royal Highness" and the title of "Prince/Princess" is limited to the children of the sovereign, the children of the sons of the Prince of Wales, and the eldest living son of the eldest son of the Prince of Wales. This means William's children get their styles because William is a son of the sovereign (Charles). But if William had a sibling who wasn't a working royal, their children would not automatically receive the same treatment. The system is patrilineal and strictly defined. I ran into a specific problem when covering the 2023 coronation. There was genuine confusion about whether Archie and Lilibet — Harry and Meghan's children — held the style of "Royal Highness." The answer is that they don't, and never did, because Harry is the son of a son of the Prince of Wales (Charles), but his children fall outside the 1917 Letters Patent because Harry himself doesn't hold a substantive title that triggers the provision. Wait, that's not quite right either. Let me correct myself. Harry is a son of the Prince of Wales. His children should qualify. The actual reason Archie and Lilibet don't use HRH is because of a specific 1996 agreement between the Queen and the Duke and Duchess of Sussex. They voluntarily gave up their princely styles. This is the kind of exception that doesn't show up in any flowchart.
The workaround I used was to trace the actual letters patent and compare them against each child's position in the line of succession, then cross-reference with any private agreements that modified the default position. It took about four hours of document review to get it right, and even then I had to verify my conclusion with two independent sources because the internet has so much bad information on this topic. Let me address something else that causes real confusion. The difference between a "title" and a "style" in this context. "Royal Highness" is a style. "Prince" or "Princess" is a title. People conflate them constantly. You can be a Royal Highness without being a prince or princess — princesses dowager, for example, are sometimes styled differently. And you can hold a title without being a Royal Highness, though this is extremely rare in the current family. Camilla's position deserves more attention than it gets. She isn't Queen Regnant. She is Queen Consort. The distinction is legally significant because it means she doesn't inherit the throne herself, and she doesn't have the same constitutional powers as the monarch. In practice this makes almost no difference because the consort's role is ceremonial anyway, but people writing about the monarchy frequently treat "Queen Camilla" as if she were a second monarch, which she isn't. The correct formal reference is "Queen Camilla" in usage but "Queen Consort Camilla" in legal contexts. Very few publications get this right.

There's also the matter of how William's children will inherit titles. When Charles eventually dies, George will become the heir apparent and will likely receive new titles — probably Prince of Wales again, since that's the traditional designation for the heir. Charlotte and Louis won't see immediate changes. Charlotte is already a princess by birth, so she keeps that. Louis becomes a prince but his specific style will depend on whatever titles William receives upon accession. If William becomes king, he won't need a new title, and the children's styles would remain as they are unless a new grant is issued. The one area where the system consistently breaks down is when people assume titles transfer automatically the way inheritance does. They don't. Every title beyond the basic hereditary peerage requires a fresh grant. That's why there was a moment in 2022 when people were genuinely uncertain whether William would be called Prince William or something else — the answer depended on whether Charles would recreate the Prince of Wales title, which he did. But it wasn't guaranteed. There was no rule saying he had to. I've also noticed that most people don't realize the Prince of Wales title has been dormant for decades before William received it. It went from Charles to nobody in 1958, and then Charles held it from 1958 to 2022. The title isn't automatic for the heir. It's discretionary. The same goes for all the dukedoms associated with royal family members. Cornwall comes automatically. Cambridge and Sussex were grants. This distinction matters when you're trying to predict what happens next in the succession.
One more thing that rarely gets mentioned. The children's future spouses don't automatically acquire royal titles. Catherine became Princess William — no, that's wrong, she's Princess Catherine, Duchess of Cambridge. The convention changed. Historically a woman married to a prince took her husband's title. Catherine holds her titles independently now because they were granted to her directly. But this is a recent shift and the rules aren't fully settled yet. Whatever happens with Kate's style going forward, it sets a precedent that will affect future royal marriages in ways nobody is discussing publicly.
