My father was adopted by my grandfather (no legal adoption document exists except the SSC/Voter ID/Pass book certificate in which my father's father name is reflecting as my grandfather's name). Later a gift deed was executed by my grandfather in favor of my father. Further my father sold the property to others without my consent though I was major at the time of sale.
As the property was acquired from my grandfather, do I have legal rights to question the sale and seek equal rights?
Thanks!
