The Duke's removal from the last vestiges of monarchical duties has not only reshaped his future - it's creating waves through his family too.
His ex-wife has now lost her duchess title and will simply be known as Sarah Ferguson.
For Sarah, sixty-six, the transition will be the most apparent.
Throughout this period, she has kept the courtesy royal post-marital designation Sarah, Duchess of York. Now, she returns to her maiden name of Ferguson.
"She will have lost a bit of cachet over this," noted one monarchy expert. "She certainly utilizes the title – including her social media profile is @SarahTheDuchess."
But the relinquishment of her status may affect her much less than the scandal she's facing separately about her own connections to Jeffrey Epstein.
Last month, several charities removed her as patron after an email from 2011 showed that she called Epstein her "greatest ally" and seemed to apologise for her negative comments of him.
Separate from her philanthropy, Ferguson also has multiple commercial enterprises.
And these ventures, are more probable to be affected by the Epstein controversy than any change in title, notes one monarchy analyst.
But Ferguson has been a remarkable endure in royal circles. She has continued recovering strongly.
"She's the supreme perseverer and expert at transforming," said one monarchy writer.
For Andrew and Sarah's two daughters, Beatrice, 37, and Eugenie, 35, there's no official alteration.
They continue to be referred to as royal princesses, which they have been entitled to since their birth.
Additionally there is no change to the royal succession order.
The prince stays eighth position to the crown, followed by his children Beatrice and Eugenie, in ninth and twelfth position in that order.
But in practice their positions are "distant" and will likely become even more remote as years pass.
Beatrice and Eugenie are also currently non-official royals, and while they occasionally take on roles – Princess Eugenie was recently named as a advisor for the King's Foundation program – commentators also say they "can't see a world" in which they would advance into royal duties.
"Regarding Beatrice and Eugenie are concerned, I think there's an appreciation of the fact that this scandal isn't about them, and it's not fair for it to impact them directly in the separate paths they are carving out for themselves," says one monarchy analyst.
"The princesses are particularly unlucky affected parties, they've had to endure quietly and have been dignified in their silence," states another monarchy writer.
In the end, there appears to be minimal uncertainty that the person who will be most impacted by all of this will be the Duke himself.
For a man who consistently enjoyed the trappings of royalty, the ceremony and the ceremony, the relinquishment of his honors is deeply humiliating.
So to not have those, on a personal level, will really matter.
