We are 4 brothers and 2 sisters. My father purchased a land property in the year 1978. For our convenience, he purchased this land property in our younger brother’s name. The many is paid cash in that time. The of my younger brother at that time was 21 years and he was not having any source of income. My father said that after some years, you four brothers get this property equally divided. But Now our younger brother is refusing to give us a share in that property. What is legal way for us go get a share in this property ?
