Ex director of bank (lady) falsely charged for cooperative bank cases

My father was president for one cooperative society and that bank has gone in loss now. My mother was ex director of bank. Many lawyers had FD in bank and now they are purposefully filing case in consumer court against my mother (she has home and site under her name) saying my father was president and done fraud in bank and have made properties in wife name. They do not have any proof that money has been taken by my mom to make those properties. Still by bribing judge as they all are lawyers have made judgement against my mother to pay all FD amount. It's about some 1 crore amount and we do not have that much money to pay. Also bank is in loss so without doing proper investigation on bank simply they are trying to loot from single person who do not have done any wrong. Court has issued summons for my mother. What we need to do in this scenario as we do not have anybody support because opposition is lawyer.
