My brother's wife filed a fake case against my brother and parents

My brother got married 1 and half year back. My brother is posted in a village in Punjab and lived with wife for 2-3 months, later when she got pregnant, due to unavailability of good medical facility he left her with my parents in Jaipur. But his wife used to live mostly at her parents house which my parents never objected/denied. In all this duration, her aggression/language/tone was becoming abusive. Three months back my brother got transferred to Delhi and she immediately wanted to shift with him which he was unable to do that point of time due as not finding suitable place as per budget. On this Diwali, her parents came and threatened my brother and parents for worst situations, if my brother will not take her immediately. Where my brother replied that if they will keep threatening unnecessarily, he will never take her along. Later in this month first week he took her to his rented place in Delhi. After a week in late evening, she started argument with my brother and left house with kid and said that it is part of plan which her family thought on Diwali. My brother tried to stop her but she packed her bag and left. After few man/women came to brother home and threatened him. In between my brother tried to call her, which she did not pick and also informed her parents but they also not taken it seriously (looks like they were aware of). Two days back received a SMS from Jaipur family court to present with parents. All possible allegation physical torture, mental torture, no food, locking in room, asking money, keeping like servant, try to kill, abortion, no sexual relation etc. has been said. Fake report of private hospital of physical torture of the night when she left home has been submitted. My bother still said in front of committee that he has no problem with wife and wants to take her back to home. Her family is full of advocates and they have good contacts, also presenting fake reports. My brother is afraid of as we hear lot of such stories where in fake cases also lot of harassment happens. Please suggest.
