A landowner in Tamil Nadu purchased agricultural land in 1987 via an oral agreement and sale deed, paying all taxes and maintaining possession since. However, the Tahsildar has rejected the Patta application, demanding the parent deed in addition to the sale deed. While the current possession and cultivation are documented, the lack of a registered partition deed and the missing parent deed are the key issues. Advice suggests trying to obtain the parent deed from the vendors, securing an indemnity bond, or appealing the Tahsildar's decision, especially given the long period of undisputed possession.
