A former tenant was contacted by a debt collector, in relation to a claim of damages made by a landlord two years before. The tenant asked the debt collector for verification, and they were provided with a letter from the landlord that was sent to the unit that they vacated, which is located in Michigan. They didn't give the landlord a forwarding address, but they believe that they registered a forwarding address with the post office. Two years have passed since they moved out. Do they still owe the money?
