Yes, if your inmate has a long sentence you can contact the chaplain at the institution and have your inmate start applying for a marriage license. Even mass murderer Charles Manson has gotten a license to marry a 26-year-old woman who visits him in prison. Each California state prison facility designates an employee to be a marriage coordinator who processes paperwork for an inmate's request to be wed. In most cases, the department of corrections approves of such weddings as "a tool of family reunification and social development." Manson is obviously a unique case. The prison holds marriages on the first Saturday of each month. His bride-to-be has said she needs to be "next of kin" in order to facilitate certain legal maneuvering and allow her to get information not available to non-relatives.
