Your father, as the owner of self-acquired agricultural land, has the full right to gift it to any of his sons, or a group of them, using a gift deed during his lifetime. The consent of the second brother, who previously sold his potential share, is not legally required for this gift deed. While a gift deed transfers ownership immediately, a will allows the father to retain control until his death. Experts suggest a gift deed is often preferable for the sons, but a will might be better for the father if he's concerned about future care.
