A 1964 sale deed for a vacant plot contains an error where the vendor missed the area in one survey number and manipulated dimensions in others to match the total plot area shown in the layout. With both original parties and their heirs deceased and decades having passed, rectification is being considered.

A thorough review of all documents by a legal professional is recommended to understand the exact situation and determine the best course of action.
