Prince Harry and Meghan Markle relocated to the United States following their exit from the British Monarchy. Despite leaving the royal life behind, royal experts explained that Archie Harrison will soon receive his royal titles, and become an official British Prince.

This will happen when Prince Charles becomes the King of the United Kingdom. The rest of the British Royals in the line of succession will move up, including the Sussexes, according to Us Weekly.

Meghan Markle and Prince Harry chose not to give their son a royal title when he was born. He is using the official surname of the House of Windsor, "Mountbatten-Windsor." But, he will, reportedly, receive his official titles when he moves up in the line of succession.

Reports said that he has the authority to choose whether he will use his titles or not. Nevertheless, he will still receive his HRH style when he reaches the age of 18.

Given that he will become the sixth person in line to the British Throne, a royal law will likely subject Archie Harrison. Speaking to the Daily Express, constitutional expert Ian MacMarthanne said that the 2013 Succession of the Crown act will apply to the Duke and Duchess of Sussex's son in the future. 

The expert explained that the act rules that all royals who are sixth in line to the throne and above must ask the British Monarch's permission to marry. Accordingly, this will, also, apply to the Cambridges, particularly Archie's cousins, Prince George, Princess Charlotte, and Prince Louis.

Reports said, however, that the conditions may still change. As noted, Prince Harry and Archie Harrison's places in the line of succession may change under Prince Charles' reign if Prince William and Kate Middleton bring forth another child. If that happens, then, the child will take the Duke of Sussex's place, causing him to move one step below in the succession line.

But, experts emphasized that the Sussexes' positions in the line of succession will eventually change when the Cambridge children get married and have kids. As noted, the Duke and Duchess of Cambridge's future grandchildren have much higher positions than the Sussexes, in general.

Whatever happens, though, Archie Harrison will likely have more authority within the British Monarchy than his parents, Prince Harry and Meghan Markle. But, this could, also, change if he follows the footsteps of his parents and decides to live far away from the royal spotlight.
