My grandmother inherited a piece of agricultural land (in 1965 in Andhra Pradesh near Tirupathi) from her mother (died in 2011) (my great grandmother), in 2012 my grandmother had transferred the property to my mother by registering the property, however my grandmother's sister claims she has equal rights on this property. As the documents in the Mandal office shows my grandmothers name (Pass book, 10 One, ROR,cultivation name), she has also taken couple of agricultural loans and has repaid it, however the Patta is with my great grandmothers name...so can someone suggest me how this will work, can my grandmothers sister claim rights on this legally....also grandmother has one more younger brother...that means my grandmother has 2 siblings....a sister and a brother...please suggest..
