@Peaceful ParrotThanks for the reply, but actually according to Italian law, civil union is "marriage between persons of the same sex". In Italy, a civil union can only and exclusively be formed by two women or two men in the presence of two witnesses, in the room reserved for weddings. There is the entrance of the two people (in our case she entered accompanied by her father and waited for my arrival in the place reserved for the bride and groom, while I entered accompanied by my son), the celebrant then reads the articles of the civil code, after which he asks first one person and then the other "do you want to join X (name of the other)", if both say "yes" then the celebrant asks to exchange the wedding rings exactly as in a civil marriage for a man and a woman .
The only difference with respect to marriage between two people of different sexes is that in the end, after having exchanged wedding rings, instead of saying "I declare you husband and wife" he says "I declare you civilly united".
I was previously married to a man and I must say that both the prenuptial procedure and the ceremony were exactly the same, in any case the municipality in Italy has always confirmed to us that the civil union act is the act corresponding to the act marriage certificate for a man and a woman who are married to each other.
In civil unions and civil marriages in Italy you have to choose between communion or separation of assets, otherwise the communion of assets automatically applies.
In Italy if you don't want to get married, but want to register your relationship by assuming certain rights and duties of the spouses and regulating assets, do what Italian law defines as "de facto coexistence" which is just a bureaucratic process without ceremonies or exchange of rings, nor declarations of "yes" and this can be done by both homosexual couples and heterosexual couples living together, but the bond ceases when one of the two changes residence and there is no right to legitimate inheritance in the event of the death of the other party.
If a man and a woman want to get married, they get married and can do so while maintaining two different residences, the wife also takes the husband's surname which must necessarily be placed after that of the girl and in addition to certain rights and duties, one has the right to inheritance legitimate in the event of death.
Instead, two women or two men who want to get married can always do so from having two different residences, there is a ceremony like in marriage, one chooses between separation and communion of goods, one chooses the family surname which will be placed before or after the maiden one / celibate, but between rights and duties the right to legitimate inheritance is also acquired.
