Duration to wait for remarriage after Exparty Divorce

Hi All, I got married in Nov 2013, after a month my ex-wife got seperated from me as she is love with some other person. After having family discussion for 6 months eventhough she didn't turned up to join me I filed petiton in Distric court on 10/05/2014 requesting her to join matrimonal home, It went for 1 year 6 months in which she has attended the court 2 times. On 2 Dec 2015 we both came to conculsion to leave separately and wrote the same on 20 rupees bond paper with our own handwriting (in presence of my mother, my ex-wife father, one mediator and both lawyers) and exchanged the same i.e her own handwritten 20 rupees bond paper is with me. My ex-wife family said they file in the court for divorce, but even after 1 month they didn't filed in court, so I filed for divorce in Distric court, she received summons but she didn't attended to court, after 2 hearings Judge declared ex-parte ( We also appealed the judge about my petiton on 10/05/2014) and I got ex-parte divorce on 30 April 2016. Now I'm getting marriage proposals and one of mandal court lawyer said to the new bride family that my ex-wife has a chance to come into my life again and she can file a case againt me in the Court, but my lawyer says I don't have to go through any further consequences and my ex-wife doesn't have any right to come into my life again. My questions are: 1. Is there any chance for ex-wife to come into my life ? 2. What are the precautions I can take so that my ex-wife won't come into my life again. NOTE: I don't know whether she got married or not, we both are Hindus. I request the Whole Lawyer community in this site for help. Thanks, Sathish
