we have a Ancestral Property (lal dora) in new delhi

it was partitioned by court in three parts each. One part to my father, one to my aunt(Bhua)and one to my uncle

now my aunt wants to give her share equally to me and my brother

what is the best possible way of property transfer from her name to me and my brother

1. Is relinquishment deed possible in this case

2. A power of attorney and a will by aunt on my father’s name and subsequently by father to our name.

3. Blood relation gift deed stamp duty charges

please help me
