Is the person you are married to, or in a civil union with, an Italian citizen?

Italy — Marriage

Civil unions count: since 2016 an Italian civil partner is treated the same as a spouse for this. What matters is that they hold Italian citizenship now — not that the family is Italian, and not that they could be entitled to it.

Yes, they are an Italian citizen → Not yet — they may be entitled through their family but it has never been recognised → No, and there is no Italian family on their side → I'm not sure whether they count as an Italian citizen →
