Hi I am Nithin I just wanted to know this My dad expired this year june There are some people with his blank cheques telling they owed my dad cash and one person has even sent a lawyer notice telling since me and my mother are his legal heirs , we need to repay the amount . But we are not aware about it at all and all the properties are in my mother's name ,nothing ever was in my dad's name. Can they do something about it ,can they file a case in this context ?
