Get Your Italian Dual Citizenship: Fill out forms for you and your ancestors indicating that you have never renounced your Italian citizenship.

One way that an Italian citizen could lose that citizenship, as provided for in Law 555 of 1912, was by renouncing that citizenship at an Italian consulate while residing abroad or alternatively by formally stating the intention to renounce that citizenship while residing in Italy and then moving abroad within a year. This was distinct from losing citizenship via a foreign naturalization, as this renunciation was required to have taken place in front of an Italian governmental official, not a foreign one.

Thus if a person claims to have Italian citizenship by birth, or that an ancestor had been an Italian citizen, the consulate at which that person is applying will want to contact other consulates covering the areas where that claimant and his or her ancestors resided to verify that none of these people every formally renounced Italian citizenship.

This is generally a formality, as cases of Italians actually renouncing their citizenship this way were very rare.

To facilitate this verification, some consulates require that jure sanguinis applicants fill out declaration forms that state that the applicant and his or her ancestors in the applicant's direct line never renounced Italian citizenship and furthermore list all the places where those ancestors lived as an adult. (Since minors could not renounce, it doesn't matter where such people resided as children.) Whether consulates really contact all the other consulates that cover the places on these lists is unknown, although in a few cases at least it seems that the consulate did so.
