Italian Constitutional Court (Corte costituzionale), No. 53/2025, 18 April 2025

Surname substitution of the adoptee who has reached the age of majority with that of the adopter. Reasonableness of the differences between the rules governing the adoption of minors and adults.

Art. 2 Italian Constitution
 

Art. 3 Italian Constitution
 

Art. 299 Italian Civil Code

1. The Italian Constitutional Court (Corte costituzionale) dismissed the issues of constitutionality concerning Art. 299, paragraph 1 of the Italian Civil Code, insofar as it does not allow, in the case of adult adoption, the substitution of the adoptee’s original surname with that of the adopter, even with the consent of both parties. The different treatment of adult adoptees does not constitute an unreasonable unequal treatment pursuant to Article 3, paragraph 1, of the Constitution.
