Saudi Justice Ministry has reportedly issued a leaflet announcing the new measures, which will make it mandatory for Saudi women to be notified when a court issues their husbands divorce decrees.
Currently, Saudi men don't need legal justification to divorce their spouses and the breakup of marriage can take effect instantly.
According to a Saudi lawyer, Nisreen al-Ghamdi, some men register divorce deeds at the courts without even telling their wives.
The new regulation coming into effect on Sunday, will ensure that "any powers of attorney issued before the divorce are not misused," said Ms. Ghamdi.
Over the past year, Saudi Arabia, a US ally, has introduced reforms to liberalize the country. In addition to recently lifting the ban on women driving, Saudi Arabia passed a new law criminalizing sexual harassment in May.
