Family not willing to give share in property to females of the house

Hi, I have a query regarding a gift deed. My parents has two kids, me and my brother. we are residing in a property which belongs to my grandmother who is alive. My parents has a belief that daughters doesn't belong to family anymore after marriage. Hence, they don't want to give share in property. Now, secretly they have convinced my grandmother to write gift deed to my brother which should be written in such a way that i should have any rights on that. I am not married, will be getting married in next 5 months. Is there anyway i can stop this legally and put objection in sub registrar office on stopping this registration of gift deed. I feel this is injustice they are doing to me, just because i am a girl. Please advice.
