The Duke's exit from the final remnants of monarchical duties has not only altered his path - it's sending ripples through his immediate relatives too.
The former spouse has now lost her duchess title and will now be referred to as Sarah Ferguson.
For Sarah, 66, the transition will be the most apparent.
Throughout this period, she has kept the courtesy royal divorcee title Sarah, York Duchess. Currently, she reverts to her birth name of Ferguson.
"She has lost a certain prestige over this," said one monarchy expert. "She certainly utilizes the title – even her social media profile is @TheDuchessSarah."
But the loss of her title may affect her much less than the scandal she's dealing with independently about her own links with the convicted financier.
Last month, several charities removed her as ambassador after correspondence from over a decade ago showed that she referred to Epstein her "greatest ally" and seemed to apologise for her negative comments of him.
Away from her philanthropy, Ferguson also has multiple commercial enterprises.
And these ventures, are more probable to be affected by the Epstein scandal than any change in title, says one monarchy analyst.
But Ferguson has been a remarkable endure in royal circles. She's kept recovering strongly.
"She is the ultimate survivor and master of reinvention," said one royal author.
For Andrew and Sarah's offspring, Beatrice, thirty-seven, and Eugenie, thirty-five, there's no official alteration.
They will still be known as princesses, which they have been granted since their birth.
Additionally there is no change to the line of succession.
The prince stays eighth position to the crown, followed by his daughters Beatrice and Eugenie, in ninth and twelfth position in that order.
But in practice their standing are "distant" and will likely become even more remote as years pass.
Beatrice and Eugenie are also currently non-official royals, and while they do sometimes accept positions – The younger princess was recently announced as a advisor for the King's Foundation program – commentators also suggest they "can't see a scenario" in which they would advance into royal duties.
"As far as Beatrice and Eugenie are concerned, I think there's an understanding of the fact that this controversy isn't about them, and it's not fair for it to affect them personally in the separate paths they are building for themselves," says one royal commentator.
"Their daughters are particularly unlucky affected parties, they've had to endure quietly and have been composed in their reserve," adds another monarchy writer.
In the end, there seems to be little doubt that the individual who will be most affected by these developments will be Prince Andrew himself.
For someone who always liked the royal privileges, the ceremony and the pageantry, the relinquishment of his honors is profoundly embarrassing.
So to not have these, on a personal level, will really matter.
