My grandparents passed away when I was just 14 years old. Now, my mother and her siblings are refusing to give me my rightful share in the ancestral agricultural land. Is my mother entitled to claim this property on my behalf?

Under Indian law, your mother cannot claim the ancestral property on your behalf. You, as a legal heir, have the right to inherit your share of the property. You can pursue legal action to claim your rightful share, even if your mother and her siblings oppose it.
