1. The two uncles can gift their 1/3 share each in the plot to your father. So your father becomes absolute owner - 1/3 + 2/3 = 1
2. Your father can gift his 1/3 share in ancestral house to your two uncles. So the 2 uncles will have 1/2 share each.
3. Stamp duty on gift deed between relatives is only 2%
4. So gift is best option
5. Your uncles can gift their respective 1/3 share in the plot jointly in favour of your father and you in one gift deed itself. So your father will hold 1/3 + 1/3 = 2/3 share and you will hold balance 1/3 share.
6. If you want the holding between you and your father to be 50-50, then one uncle can gift 16. 7% share to your dad (so his share becomes 33 + 17 = 50%) and balance 16.33% plus 33% of second uncle can be gifted to u.
6. Alternatively the uncles can gift first to your father and then your father can gift his half share to you by a separate gift deed. But you wont be able to avail nominal stamp duty of Rs 200 for gift between father and son, since that benefit is applicable only for residential and agricultural property
7. So instead of 2 separate gift deeds, one single gift deed can be signed by your uncles so that you and your dad will get 50% share each in plot
