Section 6 of the Hindu Adoptions and Maintenance Act, 1956 lays down the requisites of a valid adoption: the person adopting must have the capacity and the right to take in adoption, the person giving must have the capacity to do so, the person adopted must be capable of being taken in adoption, and the adoption must comply with the other conditions in Chapter II.
