Lilibet Diana’s birth certificate contains an unexpected detail.

Despite their agreement following Megxit that he would no longer use that title, Prince Harry identified himself as “His Royal Highness” on his daughter’s birth certificate.

According to the paperwork obtained by The Sun, Prince Harry listed “Duke of Sussex” as his first name and “His Royal Highness” as his last name.

It raised eyebrows because Prince Harry, 36, and his wife Meghan Markle, 38, chose to stop using their “HRH” titles in January of the previous year. They made this decision shortly after announcing their intention to resign as senior royals.

According to The Sun, even though they were no longer using the titles, they were never actually taken away from the two of them.

The paper revealed that Rachel Meghan Markle, ignored formal etiquette and named herself using her full, legal name.

Rachel, the former “Suits” star’s real first name, was revealed when she named herself on the birth certificate of her son Archie, who is now two years old, as “Rachel Meghan, Her Royal Highness, The Duchess of Sussex.” This incident made headlines.

This is a copy of Archie Harrison Mountbatten’s birth certificate, which was issued at the Portland Hospital in London, England.

Her title was designated as “Princess of the United Kingdom” on that particular certificate.

According to the most recent document produced in Santa Barbara, Lilibet Diana Mountbatten-Windsor was born on June 6 at 11:40 a.m. at the Santa Barbara Cottage Hospital, which is close to the family’s estate.
