A buyer is seeking advice after purchasing land in 2021, only to discover a prior sale agreement dispute from 2010. The original seller (A), who is claiming Scheduled Caste status and challenging the sale under the PTCL Act, had previously sold the land to an intermediary (B) who then sold it to the current buyer. The buyer is concerned about the validity of their registration, especially since the land is Inam land, which has specific abolition laws. The seller (A) appears to be attempting to reclaim the land by challenging the registration.
