My question involves a roommate in the State of: Ohio
I have two roommates. During our stay in our apartment myself and one roommate paid on time. I did not know the other roommate wasn't paying until we moved out and the landlord told me he was keeping our security deposit as rent owed for the third. Now he says he may sue us for the rent she owes, a total of $2900, not including court costs. All three of our names were on the lease, but she was the only one that didn't pay. He says he has to sue us all because we rented as a "unit". Is this correct and is there any way a judge an make us pay her share if we can prove we paid? Or do we have to pay the rent and then take her to small claims?
