Dear Madam,
My answers are as follows:
My question is we hardly have evidences for proving that my sister had been sent out of her matrimonial house and other complaints we have on them.
Ans: Nothing to bother. Just file a DV case. It is enough such allegations are made in the petition.
So, will there be any fine or any kind of punishment for my sister if she cannot prove the compliants she is making against her husband and in-laws?
Ans: There cannot any punishment because the accused have no such chance except in rarest of rare cases. Allegations and counter allegations are common in family disputes.
Could you please explain me more about RCR case?
Ans: If it is decreed and the spouse not cared to join the other spouse then after one year from the date of such RCR decree a divorce case can be filed and it will be allowed.
But can a case be filed for the attempt of bigamy? if so, what case is that. I heard bigamy can be files only after the actual occurance of second marriage.
Ans: Before attempt of bigamy, your sister can file a civil suit and get an Injunction Order against him and all the concerned on not enter into any engagements for second marriage. Police Complaint can be also be filed to prevent such act.
