How do I file for a divorce when I live in one state and my husband is incarcerated in another state?

As long as you have been an Ohio resident for more than 6 months you would be entitled to file, and obtain, a divorce here. By law we can serve your husband in care of the prison warden. The cost would vary according to the issues involved, property and children , however, it sounds as if it would be fairly straightforward and at the lower end of the cost scale.
