Civil Suit And Contempt Of Case Discussion

I purchased 1acre land from a lady of my village. Lady got the land from her husband via decree. Her husband got that land from ancestors. Both lady and man are alive. They have 8 children. 5 boy and 3 girls. Now out of 5 boys 2 boys filed civil suit against her mother and father claiming that it is anencetral property and they have also their share in it and how can his mother and father can sale the land. Below are the points related to sale of land. 1. We made agreement on 27th Feb 2017 and in March 2017 their sons filed civil suit case against her mother but we did not have any clue about it. On 16-05-2017 we got it registered and unfortunaly the sons also got status quo from court. Now I feel I am in trouble because the sons also filed contempt of court case against me too. Now please suggest what will happen. Will I have to loose the land as well as money...?? Please suggest. Also tell me the time duration to become the party in civil suit because still I am not any party.
