The Duke's exit from the final remnants of monarchical duties has not only altered his path - it's sending ripples through his family too.
His ex-wife has now surrendered her ducal status and will simply be known as Sarah Ferguson.
For Sarah, 66, the transition will be the most visible.
For all these years, she has kept the courtesy royal post-marital designation Sarah, York Duchess. Now, she reverts to her birth name of Ferguson.
"She has lost a bit of cachet over this," noted one monarchy expert. "She certainly utilizes the title – even her social media profile is @SarahTheDuchess."
But the relinquishment of her status may impact her much less than the controversy she's dealing with independently about her own links with Jeffrey Epstein.
Recently, several charities dropped her as patron after an email from 2011 revealed that she called Epstein her "greatest ally" and seemed to apologise for her public criticism of him.
Away from her philanthropy, Ferguson also has various business ventures.
And these ventures, are more likely to be impacted by the Epstein controversy than any change in title, says one royal commentator.
But Ferguson has been a remarkable endure in royal circles. She has continued recovering strongly.
"She's the ultimate survivor and master of reinvention," said one monarchy writer.
For Andrew and Sarah's offspring, Beatrice, thirty-seven, and Eugenie, thirty-five, there's no official alteration.
They continue to be referred to as royal princesses, which they have been granted since their birth.
Additionally there is no change to the royal succession order.
Andrew remains eighth in line to the crown, succeeded by his daughters Beatrice and Eugenie, in ninth and twelfth place in that order.
But in reality their standing are "distant" and will probably become even more remote as years pass.
The princesses are also currently non-official royals, and while they do sometimes take on roles – Princess Eugenie was recently announced as a mentor for the monarch's charity network – experts also suggest they "don't envision a world" in which they would advance into royal duties.
"Regarding Beatrice and Eugenie go, I think there's an understanding of the reality that this controversy doesn't involve them, and it's not fair for it to impact them personally in the separate paths they are building for themselves," says one monarchy analyst.
"The princesses are particularly unlucky victims, they've had to suffer in silence and have been dignified in their reserve," adds another royal author.
In the end, there seems to be little doubt that the individual who will be most impacted by all of this will be Prince Andrew himself.
For someone who consistently enjoyed the trappings of royalty, the pomp and the pageantry, the relinquishment of his honors is deeply humiliating.
Therefore lacking those, on a personal level, will really matter.
