A person to whom i m getting married after his divorce has filed the case due to dissertation and no intrest for making relationship from the first day...its 4 years of unsuccessful marriage. She is working and ready for the divorce but demanding 28 lacs rupees for settlement.Is this amount is right? She was working and never help in financial matters of the person.not a single money. Is this totally fine to demand such a huge amount in this case when they only spend 7-8 lacs in the whole arrangement. My to be husband filed the case firsf on the basis of cruelty and dissertation. And his wife is torturing him that if you didnt give the money then she will not let him take divorce..we have proof that my to be husband tried to make relationships in the starting but she denys that. Her father is also giving him threat that he will not let hime be free easily.kindly guide us.what to do?
