Yes, several penal facilities allow inmates to marry. You would first speak with the chaplain at the prison. The majority of chaplains don't believe prisoners should be allowed to marry. They feel as long as someone is incarcerated and not contributing to society, it goes along as part of the punishment. They don't deserve to be married while in prison because it's a privilege." That privilege extends to spending time alone with a new wife, something that doesn't happen after most prison marriages. The federal prison system does not allow conjugal visits at all, though some inmates who are nearing release after long sentences and have good conduct records will be allowed furloughs of a few days to re-establish family ties.
