My brother Dinesh signed a surety for a loan from a chit fund company for his friend Praveen along with Praveen's wife and Moorthy. Dinesh is a government employee, Praveen's wife is a homemaker, Moorthy and Praveen are buisnessmen.
Praveen had failed to pay his loan and the chit fund sent notice to all the sureties. My brother was the only only one to respond to the notice.
Now the chit fund is saying that since Dinesh was the only one to respond to the notice he is liable to pay the full amount.
What should My brother do? Please advice.
