After turning 18, Louise was again offered the title of Princess Louise but declined.

Meanwhile, her brother James, who turns 18 in December 2025, is expected to make a similar decision, according to Roya Nikkhah, royal editor for the Sunday Times.

Nikkhah previously noted that it was “highly unlikely” for Louise or James, who are 15th and 16th in the line of succession, respectively, to use the titles offered to them.

Their parents prioritized giving them as “normal” a childhood as possible.

“We try to bring them up with the understanding they are very likely to have to work for a living,” Sophie, 59, shared with the Sunday Times Magazine in 2020.

She added, “Hence we made the decision not to use HRH titles. They have them and can decide to use them from 18, but I think it’s highly unlikely.”

Continuing, Sophie explained, “What’s normal? They go to a regular school [they both attend top independent schools]. They go to friends for sleepovers and parties.”

“At weekends, we do lots of dog walking and stay with friends. I guess not everyone’s grandparents live in a castle, but where you are going is not the important part, or who they are. When they are with the Queen, she is their grandmother,” the Duchess of Edinburgh said.
