A user is seeking advice after discovering a forged document related to land purchased by their father in 1968. Although the patta was in their mother's name until 2022 and taxes were paid, an Encumbrance Certificate (EC) revealed their mother's signature was forged in 1971, leading to the patta being transferred to another person. They are asking for guidance on how to file a case with the Registration Department in Tamil Nadu and are exploring options like consulting a lawyer or applying to the District Collector.
