Case filed under sec 125 crpc

We were a Family of 5 members i.e. myself, my mother, my wife, my son & my brother living togather in Mumbai. My brother got married in Dist - Patan, North Gujarat on Feb, 2008 & from May, 2008 onwards my brother & his wife are not staying with us & are staying in a Rented Premise in Mumbai since then. She has filed a case under sec of CRPC 125 in the court of Principal Judge, Family Court Patan - Gujarat (N.G) against my brother & demanded Rs. 15,000/- per month since the day she left my brother on September, 2016 without informing him to her maternal home in Gujarat. She has levelled the allegations against all of us that as she could not conceive any child due to my brothers impotency (Baseless allegation without any proof) she would like to have Divorce. She has also mentioned in her case that we have mentally & physically tortured her which is not true as we have not met or interacted with her since they both had willingly decided to stay seperate. Kindly assist us in the above matter at the earliest pls.
