A user is seeking advice on how to transfer a piece of land to their mother's name after their father's passing. One survey number was missed during the initial transfer as it wasn't listed online. Now, the user wishes to build a house on this land but faces difficulties due to the missing online record, despite possessing physical documents like 13B & 13C and an old passbook. Advice suggests a potential release deed to transfer the property to the user's name first, followed by obtaining construction approval, and possibly converting agricultural land. It also enquires about other legal heirs and if the revenue department was contacted about the missing survey number.
