Cheque case

All cheque leaves issued to a person and cheques, if any, issued by the person, become invalid on the death of the person. But if there was money in the account on which the cheques were drawn, bona fide creditors can have a claim on that amount. But they will have legally establish their claims. Creditors can have claim also on any other estate left behind by the deceased. They can have no claim on any property, which was not in the name of the deceased. You submit death certificate to the banks where your father had accounts, if you have not already done so.
