The case, regulated by art. 4 of Law no. 91/92, generally refers to cases that are applied only on Italian territory. For the relevant regulations, please refer to the Ministry of the Interior.
Here we point out the sole provision that allows children of an Italian parent by birth to acquire Italian citizenship if the parents (or guardian) declare this intention. If the declaration is submitted within one year of the birth of the minor (or from the subsequent date on which filiation – including adoptive filiation – is established), the minor can acquire Italian citizenship even while continuing to reside abroad; if, on the other hand, more than one year has passed since the birth, the child must legally reside in Italy for at least two continuous years for the declaration to take effect.
If, having reached the age of majority, he or she wishes to renounce citizenship, he or she may do so, provided he or she has citizenship of another country.
Declarations on behalf of individuals who were minors as of 24 May 2025 and who are children of citizens through ius sanguinis, as referred to in letters a), a-bis) and b) of article 3-bis, paragraph 1 of Law no. 91 of 5 February 1992, may also be submitted by 11:59 p.m. (Rome time) by 31 May 2026.
To acquire Italian citizenship pursuant to art. 4, a contribution of EUR 250 is requested in favour of the Ministry of the Interior.
