Correction deed for change for flat number after 12 years

A rectification deed should be executed after mutual consent of all the parties to the main deed. All parties to the original deed should jointly execute the rectification deed as well.In case the original deed is registered, the rectification deed should also be registered. The requisite stamp duty and registration charges should be paid as per the laws in force in the State. For errors such as spelling mistakes, the stamp duty and registration charges are Rs 100 each. In case a rectification deed relates to the area, names of the parties, or extent of the property, the stamp duty and registration charges as applicable to a conveyance deed are payable.
