she had registered the land its a sale deed however she has given him without any sale amount but she showed on papers that she received the selling amount from her nephew in advance. The property is inherited from my father's father and his father. is it so that once the mutation has been done in the name of her nephew then i can not challenge this deed??
in registration paper it has been mentioned that there is no other shareholder of the land except my mother . where as i am the only heir of my mother.
If this property was left behind by your father who is reported to have died intestate, then as a legal heir to your father you have a share in the property as your right.
You can file a partition suit seeking your legitimate share in the property, dont worry even if the property is sold by your mother without your consent, the sale deed is not valid in law and it is not binding on you, you can stick to your cse alone.
Let she come to the court stating that she already sold the property, you can pray before court to direct her to cancel the sale deed and allot you your entitled share in the property by dividing into metes and bounds, good and bad soil.
You have to fight a strong legal battle by regular follow up through your advocate.
