How can husband fight against false dowry, domestic violence comp

My wife has been staying with her parents since past 2 years , she left the house on pretext of illness and now refuses to come back and stay with my old parents, she is forcing me to move her into a separate house and as my parents are old and i am the only son i cannot do that. Inspite of lots of cajoling she is adamant and than she sent me a khula form of divorce, which i was ready to accept but than the elders stepped in and the Khula did not happen as they said we should give it one more try. i tried hard in this attempt but she is still adamant and now i hear her family is threatening to put false case against me and my family for false dowry, domestic violence, harrassment etc which is absolutely baseless. How do i safe guard myself what steps should i take to safe guard myself. I have email records of the earlier Khula form sent which clearly spells that there is no dowry demand, mental harrassment etc mentioned in email sent by her uncle on stamp paper which were to sign on the agreed khula date..Please suggest how i can safe guard myself and will this evidence help me protect. Also what action should i take against this to salvage my family image. I have tried my best t obring her back to the same house but she is not ready. please advice
