One time each three months a convicted prisoner is entitled to extended several days visit. By the law, the Correctional System allows to visit them only by close relatives, family members (children, parents, spouse). If we expanded the list, I think it would make it easier for friends or girlfriends to come to those who don't have close relatives. Including partners. This stimulates a person to social connections, it would be easier to adapt for him, he wouldn't lose contacts.
We must clearly understand that marriage we are talking about is not made in heaven. And it is not a religious ceremony, like we are always explained. Marriage is a civil condition. It solves purely legal issues of relations: to inherit, to donate, to divide common property, to adopt children, etc. Including the allowance to visit close people in prison. During the first year of imprisonment, the majority of convicted women lose contacts with their common-low husbands, because they don't have the right for an appointment without the assistance of the administration. Although under the same conditions a common-law wife can get on an appointment with her husband. It's a women rights violation.
An egregious situation. The imprisoned women are seldom visited, they are often abandoned by their husbands. And still say – wait until we register your marriage. Common-low wives are allowed to visit male prisoners, and common-low husbands are not. It's widespread. In that sense women are much more difficult. What if she hasn't got a man? The situation is normal if someone is ready to wait, to support, and there is a place where you can come back. Being in a contact with someone close is a kind of socialization. It reduces the risk of recurrence after all. But if no one comes to see her, or if it isn't allowed – the problem is getting worse for everyone.
