My elder brother had three Trailer loories, financed by repluted finance company in the year 2000. Since my brother defaulted in payments, they have seized the vehicle in the year 2002 end or begining of 2003. They sold the vehicle at a lesser price to another person whom I know and without knowing, he told that he got it at a cheaper rate with the understanding of the company. The problem is that they didn't tell us that we owe them and suddenly now demanding to repay the balance with interest till date. I am the surety for this. am i liable to pay or will they take action?
