Cyber crime complaint to retrieve cell phone recording

Cyber crime complaint to retrieve cell phone recording I am looking at a possible divorce suit with my husband (married under Hindu Religion), owing to his indiscretions with an unmarried girl. I dont have enough proof to confirm his adultery. 1. Is it possible for me to give a complaint to the local Cyber Crime Police and request them for the FULL CONVERSATION between my husband and that girl? Because if i show just call timings they may be argue that they were talking about official issues (same office) 2. Can i request the call recording even if the numbers are registered under his name, as his wife? 3. How long are these phone conversation recordings stored by cell phone companies.. can the Cyber Crime Police retrieve such conversation from even 6 months before? 4. i have recorded a conversation between them which was on speaker for a few mins using my cell phone. Is it illegal to show this cell phone conversation in court because i was not in the call? 5. Will family court accept such cell phone recordings as evidence for adultery Thank you,
