I think it would be nicer to let him keep the name, but not the privileges of the Duchy. He is still the father of Elena's children, who have grown up knowing that their father is the Duke of Lugo.
The Juan Carlos era marked a major change for Spanish nobility. All Spanish titles are courtesy and totally meaningless. They carry
no privileges or prerogatives, and this is one among many steps taken by JC that have endeared him to the people of Spain. Except for few titles of nobility such as that of Duke/Duchess of Alba which carries major international prestige due to local history, its connection to the british peerage, the immense fortune etc, most Spanish titles have no attached value other than standing as testimony of aristocratic origin.

The is crucial in this case, without it 'Duchess of York' is something like a surname, rather then a title.
Actually, should Andrew remarry, his new wife would be
"The Duchess of York" without her first name in front of the title for the simple reason that the definite article
The refers to the one and only holder of the substantive title, the new wife. Sarah lost both, her style (ie the HRH) and her substantive title and was left with the honorific, courtesy (and meaningless) title,
Duchess of York preceded by her first name, in order to distinguish her from a possible new wife of the Duke. As a non-British European, I am intrigued by the fact that Britain has turned the study of peerage and titles into a
precise science. By merely rearranging the title ie a) by deleting the definite article
The and b) prefacing it by the holder's first name, justice is served to the divorce'e by granting her continued status and dignity, whileprecluding confusion between the holders of the substantive and the courtesy title!!

I would be inclined to agree with you that Jaime de Marichalar will lose his title the moment divorce becomes in effect, not only because the Infanta is
a suo jure [in her own rights, by royal decree] duchess and he, only by association, but also due to the fact that if the marriage gets annulled by the Catholic Church, the annulment would be somewhat in conflict with his matrimony-acquired titular status, should it remain unchanged.
As for the next husband, should he not be a nobleman, my intuition tells me that he would not be very eager to "inherit" a title previously held by husband #1
and the father of his step-children. I feel there is something psychologically awkward there. After all, it is only an
ad personam peerage and even without it he may still be styled HE and even get elevated to a grandee.
