Section 17(1)(d) of the Registration Act clearly states that lease in excess of a period of one year requires registration. The lease deed no doubt stipulates the initial period of lease as 11 months and if the recital has stood only thus, the document would not have required registration. If the document also contained a provision for an increase in rent after a period of 3 years then the recital will have to be seen in the context of the whole document and that would itself be a proof for the fact that the lease was not merely for a period of less one year but for a period in excess of three years and therefore, the interdict under Section 17 was attracted. This point was dealt with by the Privy Council in Durga Prasad Singh Vs. Rajindra Narain Bakshi 1913(40) IA 223 that confirmed the decision of the Calcutta High Court where it held that an agreement to reduce the rent was inadmissible in evidence to vary the terms of the lease. The Court held that a document which would vary the essential terms of existing lease such as the amount of rent, the time for payment of rent thereof and the consequence of default amounted to a fresh lease. In so far as the provision for increase after a period of 3 years was concerned, therefore, it should be taken as a clause where a lease operated for a period in excess of 3 years when the clause for enhancement was operative. This must, therefore, be taken as an alteration for terms for a lease in excess of 3 years and therefore, the document was inadmissible. The inevitable consequence of a variation in terms of lease for a period in excess of one year was dealt with an English decision in Sanderson Vs. Grave (1875) LR 10 EX 234 in the context of English Statute of Frauds where Bramwell B had said "Unless a note in writing is necessary in every case of alteration, it
