MARRIED couples in Italy will no longer have to swear to be faithful, under a new law that could remove the word “fidelity” out of marriage contracts.

It’s archaic and old-fashioned to require spouses to be monogamous, senators who signed the bill claim, according to The Local.

“[It’s a] cultural legacy from an outdated and obsolete vision of marriage, family, and the rights and duties of spouses,” states the bill, which recently passed into the Italian Senate’s Judiciary Committee.

Supporters — who want to open the door to open marriages — cite a ruling from Italy’s top court, which proclaimed that judges can’t blame divorce “on the mere failure to observe the duty of fidelity,” according to the news site.

It shouldn’t be up to the state to impose its values on couples, they said.

The bill also points out that the definition of marriage and family has changed drastically in the decades since the original law passed.

“Until not long ago, only the fidelity of the woman was sufficient to guarantee the ‘legitimacy’ of children,” it states.

In 2013, a poll revealed that 55 per cent of Italian men and 33 per cent of Italian women have cheated on their partners, according to The Local.
