Illegal Possession

Hi, I would like to seek some advice on following queries? My house is built on 2100 SQFT and registered on my wife name, Land was purchased in 2007 where I paid all expenses but at that time I was having a combined family where my brother and my uncle (my late father's brother) were staying with me.My wife wrote a WILL for all of us (1/3 each) while this purchased was made and WILL got registered. Now (Sep 2016) sneakily my uncle influenced my grand father (90 Years) and got entire parental property nominated to his wife. I have challenged this into court but not sure which way this will be headed to. Now I would like to get my uncle to be kicked off from my house,I approached to Police and they made us agreed to reach on agreement where I am ready to pay 1/3 price of the house and he (uncle) will vacate the house. I am an IT professional and working far from my home town (Gorakhpur),both parties were ready to execute this agreement by March 17 when I was supposed to visit my native place. Meanwhile I heard another development where my uncle went to District judge senior division and file a civil suit against me. Please let me know if there would be any impact of WILL which is still I have not changed and that’s something he is showing in the court, I heard that as long as person who registered the WILL is alive ,can change many times. Since WILL is still not revoked, would it give any edge in this case to my uncle? Currently he is in possession of half of property. He has also got electric Bill on his name by bribing to electricity department. Please let me know what are the options left for me to get him vacated from my property? Thanks Sanjay
