A-Owner of property (who's name is in RSR of 1956)
B -Son of A only beneficiary of unregistered will for 10acres dated oct 1986 of A (Deceased dec 1986 when B is Minor) and later on B got his name in ROR,1B of govt records.
C & D are married (before 1985) daughters of A.
...B barrrowed a big amount from E by against registered sale deed dated 2015 for 10 acres (as security)to E and after long time 3 years in 2018 when E tried for recovery borrowed+internet crossed total worth of the property.then after sevaral sittings
with local gently men and giving more and more time to clear loan the local gentle supported to E to get possession of property and to get names entered in ROR ,1B.
But still B is not happy with what is happening as he lost everything and is zero now so his appealing to officials that E cheated him he didn't sold the property to E he just executed sale deed as security for amount barrowed.
Now E kept property for sale .
But he don't have original copy of unregistered will.
Now my query is can i purchase this property?
What are chances B have to challenge legally if I purchase the land?
