Can an old electricity bill of my husbands go onto my account?

Two years ago my at the time boyfriend and I got an apartment and I put the electricity bill in my name. Soon after I got a letter stating I owed money on a house that he had previously lived in and had an outstanding bill.

I talked to the company and told them I had never lived at that house and I didn't owe them anything. They proceeded to hound me and told me I needed proof that I didn't live there. I got off the phone with them and called my father(a sheriff of the county over and the home I was living in at the time that this bill had happened). My father called up the company and about 5 minutes later told me it was taken care of and that they shouldn't bother me again.

We recently got married(last month) but we have separate accounts on everything. The only thing that is in both of our names is the apartment.

They sent me the bill again saying that recently reviewed my account and saw I had an outstanding balance for the house I never lived in.

Can they legally send me my new husbands old bill when I never lived there and he is not on this electricity bill?
