When purchasing a plot sold via a Sale Deed in 2006, which originated from an Agreement of Sale cum GPA executed in 2004, a buyer is concerned about the original owner's (A) unavailability. The seller (C) claims A died in 2014, but cannot provide proof, raising doubts about whether A was alive when the property was sold in 2006. The buyer is seeking advice on how to proceed, including whether to issue a public notice and protect themselves from future claims by A's heirs, especially considering legal changes regarding GPA validity.
