Gpa & noc

Hi,

I bought property paying 25% of amount.Unfortunately later I came to know that land is getting registered by GPA holder(not irrevocable) to buyers.

As per supreme court verdict I understand no more GPAs for transfer of title.

If I have NOC(No objection clearance) from actual land owner Plus(+)registration in my name(as govt is doing dont know why).Is this safe to buy??if not is there is any way ?

Thanks,

Ameen...
