Effective date of document REGISTRATION ACT 1908
– 1. A document takes effect from its date of execution and not from date of registration. However, if the document states that it will be effective from a particular date, it will be effective from that date [section 47].
2. Document registered has priority over oral agreement - Any non-testamentary document registered under the Act takes effect against any oral agreement relating to the property. The only exceptions are :
(a) If possession of property (movable or immovable) is delivered on basis of such oral agreement and such delivery of possession is valid transfer under any law
(b) Mortgage by deposit of title deeds takes effect against any mortgage deed subsequently executed and registered which relates to same property [section 48].
