I have purchased an agricultural land in Tamil Nadu last year 2015 from a person X. This land was transferred from X's mother through succession law after mother's death in the year 2000. Patta, Chitta and revenue documents were changed to X's name. Person X was the only child of her parent. I have purchased after verifying all the documents and EC for the last 32 years. No issues in EC. It was a self acquired property of X's mother.
Now, another person Y came and encroached land saying that he has a WILL written by X's mother before her death. We have found that the WILL is a registered one, but not probated so far. Since it was not probated, it didn't come in EC. Person Y filed a case mentioning that he is in the possesion of the land from the year X's mother's death in 2000 and land belongs to him. Person 'Y' is politically influenced person.
Can you please advice what to this case. I don't know why the person Y didn't disclose the WILL for the past 15 years. He didn't obtain probate also. What should I do this case? I lost sleep due to this. What is the probability of winning this case. How to proceed?
