Though the registered gift deed is valid, but if you do not enter in the 7/12 record, the title will be defective. First you have to check up the 7/12 record and see whether anybody has entered into it. If nobody is entered in it, atleast now you have to give an application Revenue Division Officer (Superior to Tahsildar) for inclusion of your name. There may be some late fee and penalty.
In case somebody name has been entered in the 7/12 record illegally, you have to challenge the same with the above Revenue Divisional Officer and simultaneously you have to file a title declaratory suit against the person named in the 7/12 record and all concerned and get it decreed by civil court.
