498a and DV

Hello, I have filed 498a and DV on my husband and in laws. As my in laws are in andhra B report on my in laws and chargesheet applied only on my hubby, i am not interested in going for any reinvestigation as my husband is ready to compromise and settle and divorce. Problem here is i am not from a good family background, my father is drunker, my first sister got divorce 10 years back only, my second sister also separated from her husband and her husband filed for divorce and the case is running from 3 years. My husband want to use this weak point and trouble me after divorce, i am sure about this, i know he already met commissioner and some more persons regarding and want to complain or planning something, i dont know what it is, but i am sure he want to trouble saying that all my family members are getting married and giving divorce to husbands for alimony and loot money. But my first sister has not taken even one rupee as alimony or maintenance towards her kid also till now, and second sister tried to patch up soo much even after her husband has filed for divorce and proof is there even for that. Even i am not interested in looting his money, i am just asking to pay for my kid education amd maintainance, i am ready to give my kid to him after 12 years for her better future if he is not married and give back the maintenance money also to 50% of it and also gold to him as soon as i give her custody to him and ready to sign on agreement too. I too asked him so many times to take me back after filing the cases and have proof for that as well. But my first sister is looking for a second marriage now and he got know that and has proof also as she registered in matrimony site. I understood that my hubby and my second sisters hubby are planning something. Here my question is After all reading the above information, do u think they can trouble our family? I have many voice recordings to prove that my husband use to beat me ruthlessly and pressed my neck few times after which i fell unconscious also. But i didnt know that there are so many terms and conditions under 65B evidence act. So i deleted that original audio recording as i recorded it in some others mobile and only have it on CD and mail. I have sent them to his friend and my husband agreed in a message that it is fact and true. Is this enough to prove it in the court? I read in kanoon few lawers saying that audio recording can be rejected by court under some conditions and should prove that its not tampered or something, As i am sure that he wanted to trouble in the future, before signing divorce papers i want to collect a strong proof which will not be rejected by court, i tried to read about 65B evidence act after which i could not understand much, So please tell me what kind of voice recorder or video recorder can i use? Is just a voice recorder in iphone is enough, i prefer voice recorder as it is easy to record, if you feel it is not enough then i will go for video recording only, Please do help me with this.? Is automatic call recorder in a phone can be a strong proof?
