If prior to a registered gift of self acquired immovable property, both donor and donee enters into an unregistered agreement that donor will gift the property to donee and also donee will give some things to donor, then can such a gift be cancelled? If in addition there are other proofs of sufficient excesses and coercion by donee and indication that donee stands to benefit overwhelmingly by all these transactions, then will these help in the gift cancellation? Further if ten years has passed since the gift deed, and donee has got his name mutated and erected some constructions on gifted property then can donor still cancel the deed on aforesaid basis? Please give some citations for support of case if cancellation possible. Thank you.
