A Pune flat owner has discovered that the open terrace area is missing from their Index 2 document, although it's correctly stated in their sale agreement. They are concerned about how this omission might affect their property rights, especially with reconstruction and conveyance deeds underway. The advice given clarifies that Index 2 is not the final title deed and can be rectified by applying to the District Registrar with supporting documents, even before the conveyance deed is finalised.
