I have a purchased a property in the year 2010 from a person A. The Person A bought the property in 2007 from another person B. Person B's mother original owner of the property died in the year 1999. A third person C now entered into property and claiming that he is having a WILL written by person B's mother in 1999 before she died. She died at the age of 90. He doesn't have the original copy of the WILL. It is lost I think. It is found that the WILL is registered and not probated. I am in a confusion on what to do. He is coming after 12 years of person's B mother death. Is it possible to get my property back if I file a case? Please provide your suggestion on what to do.
