For your information a Will cannot become a title document until it becomes enforceable.
It will become enforceable only upon he death of the Testator.
Transfer of a property mentioned in the Will by a gift deed before the Will becomes effective is not an illegal act.
A Will can be cancelled by the testator anytime during the lifetime.
If the gift deed was executed during the lifetime of the owner b y a registered deed, then it is very legally valid and cannot be challenged until and unless the owner or the party having interest in that property challenges the same on the grounds of fraud played by the donee/beneficiary to acquire that property.
As of now you are not having any interest in the property that has been bequeathed in the Will which is yet to become valid or come into force.
