There was a 20 acres property which initially belonged to Mr Shiv (my great great grandfather) since pre-independence. He had two son Mr. Nikhil & Mr Akhil (my great grandfather). Mr Shiv died during 1950's (probably!!) The property was then transferred/inherited/passed on to both of his son equally. From where, Mr Akhil (my great grandfather) received/inherited his 10 acres share. Mr Akhil died during 1978. He has one son Mr Jagan (my grandfather). In 1994, Mr Jagan recorded his name in CS/LR record. Mr Nikhil has two son Mr Sam (my uncle) & Mr Subal (my father) who was born in 1964. Mr Subal has three son, of is me i.e. Mr. I (born in 1985). Mr Jagan in 2005 willed the property in name of Mr Sam's wife (my aunt).
Summary: Shiv (my GGGF) -> Nikhil & Akhil (my GGF)-> Jagan(my GF)->Subal(father)
No share was given to my father. Is this legal, can this be done?
