if OC is issued then where is the question of taking any fit out or soft possession???
at the highest your registration will be pending due to disputes between the builder and the owner
if OC is there then you can take the possession
fit out possession is given when there is no OC
Here you say that OC is issued to the builder
so where is the question of giving any fit out or soft possession then?
since you have made 100% payment and the OC is also there, nothing stops you from taking the possession
the only pending aspect would be the registration of agreement for sale
im surprised why till now your agreement is not registered!
as per law upon receipt of 10% sale consideration the builder is mandatorily required to register an agreement in favour of the flat buyer
