My father was expired recently. He signed a blank pronote in the name of X. Now X has lodged a suit against us i.e, legal heirs for 5 lakhs. We dont know the exact amount taken by my father. Court issued a pro order holding the process of arrears and benefits. We are sure that my father was not availed that much amount. He would have availed 50K-100K and ready to pay that. But they are asking for the nearly 6 lakhs with interest. We dont have any prrof from our side. Please guide us in this regard
