My client's NRE brother credited Rs.1L into my clients mumbai resident saving bank a/c. The said transaction is backed with a GIFT DEED signed by both parties donor and donee in the presence of 2 witnesses. My queries are: (a) Is it necessary to execute a gift deed on stamp paper and if so what should be the denomination of the stamp paper for a gift of 1L. (b) Is it necessary / mandatory to get the gift deed notarized.
