Automatically by re-establishing residence on Italian territory for 1 year, unless they renounce it within that term of time.
By specific declaration when the conditions below are met:

The declaration for the reacquisition of citizenship must be submitted to an official of the statistics office (“Anagrafe”) of the city of residence in Italy or, in the case of residence abroad, the local diplomatic-consular authorities. The declaration must be accompanied by the following documentation:
a) birth certificate issued by the city of birth and where the birth was registered; b) documentation proving previous Italian citizenship; c) documentation proving foreign citizenship or Stateless status; d) certificate of family status or equivalent.
