Sir I have a land in Lucknow. My father is an illiterate person. In 1998 there was a person X, who did fraud with my father and my father signed on power of attorney unknowingly. X sold some parts of land. After knowing this my father cancelled the power of attorney. Some people had constructed their houses and living for more than 12 years. But still some sold land is free from construction. Can I get my land back which is not constructed? May I get possession over it? Please help me.
