I have purchased a property from a person A in 2010. Person A purchased the same from person B in 2007. Person B purchased it from person C in 2005. Person C (only daughter) got this property from her mother through succession in 2000. Person C's mother died in the year 2000. Property is self acquired property of person C's mother. Now, person Z is saying that he is having a WILL given by Person C's mother, came and occupied the property after I purchased. He is bargaining money and threating to sue me in the court. I consulted my lawyer. He is saying that the WILL cannot do anything as there were three transactions done on the property over the period of 10 years after person C's mother's death and he delayed too much in bringing the WILL. Is my lawyer telling correct? Please help.
