Wife deliberately refused divorce notice

Dear lawyers..I filed divorce against my wife who is at her native with her parents for cruelty; his father got the divorce notice infront of postman his father called up and mentioned about the legal document which I have the audio recording. But later when I checked online with Tracker ID it shows the status ARTICLE UNDELIVERED-REASON DOOR LOCKED. This is a deliberate act and dubious on wifes parent and postman. Can we move any thing in court bringing notice to them about this act alongwith audio piece for taking this act as deemed to be notice served. Accordingly they didnt appeared on date..n nw threating me n father for booking under diff..cases n engaging local police station. My qwery is what could be their next step can they go to supreme court for transfer of case without receiving the notice and appearing in court. Shall i need too file any NCR to local ps informing about the divorce case file n the threat I am getting or any PCR to be filed at metropolitan magistrate. My lawyer advise nothing doing till we get any notice from any auhority. Her persisitent and releatitive threat for suicide and asking for divorce else she would harm herself; what can we do to avoid her attempt to return to back home which is risk for her n evryone elses life. I stays in bangalore; She belongs to UP, incase any case file there how ro take relief. PLS GUIDE.
