Generally a NOC upon resale of the flat is required
Mortgage NOC requirement depends on the lease terms agreed between CIDCO and the lessee under the lease deed executed between the parties
Ask the builder to provide copy of the lease deed to check whether any such stipulation of taking a mortgage NOC is needed?
The mortgage NOC can be said to be implicitly taken under the noc obtained by the builder (through the lessee of the land) for doing construction
Thus Cidco will be obviously aware that if such construction is to be made for which it must have have given a NOC to the builder, then many flat buyers would be availing housing loan to finance purchase of the flats in the newly constructed building
So the mortgage NOC in my view would be implicitly contained in the NOC for making construction as given by Cidco
Majority of the lending banks have very incompetent legal advisers who are excessively suspicious and who do not take a practical approach
I even doubt whether such legal advisors of the banks are even qualified lawyers
They have an employee mindset and work on the diktat of the banks without applying a legal mind
