Relatives threatening to not sell the share of land

I am Hindu. Before the death of my father, he and his brother amicably with the help of Panchayat divided their ancestral property and now my mother is wanting to sell our share of land which we got in division ( we have document signed by my father and his brothers and people of Panchayat who amicably divided those property as well as Raseed of the property and other legal document) but they are threatening my mother that if we sell our share of property than we will have to face dire consequences like we will be imprisoned or other legal hindrances so what should I do in this case? Can I sell my share or not?
