Is spouse liable for unpaid cell phone bill divorce?

A divorce will seperate and allocate debts, but that's only enforceable within the divorce court. To the cell phone provider, they do not care who is married or divorced. If the phone is SOLELY in his name, then he will SOLELY be required to pay for it as far as the cell phone provider is concerned.   As divorce court would also be unlikely to give you cell phone debt that he racked up under his own name, especially on these facts. Due to the fact that he is incarcerated, you will likely need to file for an uncontested divorce. These can be tricky, but many courts provide for forms that can be used to get you started.
