Ever since Prince Harry and Meghan Markle stepped down from their duties as working royals and moved to America, they lost their royal title, and the honor of being addressed as His Royal Highness and Her Royal Highness respectively. Although Prince Harry is very much still a member of the royal family, he can no longer be addressed as His Royal Highness.
Following the death of Queen Elizabeth, the Sussex children inherited the right to be addressed as Prince Archie and Princess Lilibeth respectively. However, the official titles of the Sussex children are yet to be officially announced or updated on the royal sites.
There have been speculations that the actions of Prince Harry and Meghan may have led to the hesitation of the royal title being bestowed by King Charles himself. Not withstanding all that, the Sussex children are entitled to a royal title as stated in the rule established by King George V in 1917.
This rule ensures that the children and grandchildren of a ruling sovereign and monarch automatically have the titles His or Her Royal Highness and Prince or Princess respectively. Archie and Lilibeth could not have a title when they were born as they were great-grandchildren of the ruling monarch, Queen Elizabeth.
With the Queen’s death, and then Prince Charles becoming King, it is only proper for Archie and Lilibeth to have their titles as grandchildren. While King Charles has expressed his love for the Sussex family and children, the titles of Archie and Lilibeth are yet to be updated on the royal site, unlike others like the Cambridge family that have theirs updated.
We believe the delay in the bestowing of royal titles to Archie and Lilibeth is as a result of trust. King Charles may be hesitant because he wants to be sure he can trust Prince Harry and Meghan.
