In Maine, if you cannot pay your tax bill for the property you live on, there is something you can do. Your city or town can decide that you don't have to pay some or all of it. This is called a "poverty tax abatement."
You have been sued in small claims court. The company suing you says that you did not pay a debt, like a credit card debt. But, this is not the company who sold you the credit card (or who loaned you the money).
