Enclosed herewith copy of page 7 of an agreement for sale for flat No. 1502. In this page " along with open terrace adjoining flat No. 1504" is added. The purchaser claim that this is his registered agreement for open terrace adjoining flat no. 1504. The open terrace is not attached to the flat and having separate entry. The terrace is also a "refuge Area" as per sanctioned plan and cannot be sold.
Is this agreement is valid for purchase of "open terrace adjoining flat No.1504" along with flat No.1502. In reply to an RTI query, PIO of Sub-Registrar confirmed that the agreement is perfectly OK as the Registering Officer got powers to register documents with interlineations as per section 20 of Indian Registration Act 1908. A interim order of the Co-Operative Court also held the agreement valid and society has no right to this area. Is an open terrace and also a refuge area not attached to the flat can be sold this way. What is the remedy before the Law.
