Dear Chetan ji,
Your most of the steps are taken in a right direction but are only half done.
1) It seems that your sister is residing with you or her marriage has been solemnised at Bengluru so that’s why you people have filed a RCR case there at Bengluru.
2) It will be more better if you apply in Supreme Court of India vide a transfer Petition to get transfer the case to Bengluru as the girl is staying at Bengluru with her brothers. For that you can have my help at Delhi.
3) RCR case will not have any power to get dismissed the Divorce case, both are parallel cases and will go separately. Even if you win the RCR case and husband is not in mood to reside with his wife you cannot force it or can tke the non obayence of the judgement as contempt of court.
4) For that you have to move a application in the competent court to direct the service provider to submit call data of the particular number. which is given in only special circumstances where whether there is a direct threat of life by the possessee of the particular phone number or Court itself take the cognizance of taking the record of the phone number.
5) i) As without knowing full facts of the, we do not recommend any suggestion in any case however you can move a police complaint under 498A, 406 and 34 against the husband and his other family members who are resided in a domestic house of wife in past.
ii) But I would suggest to go for the mediation and counselling process for both the persons first independently and then mutually and by that try to resolve all the differences and re start their fresh life once again.
