Parking spaces can usually be a space delineated by road surface markings. The automobile fits inside the space, either by parallel parking, perpendicular parking or angled parking.
Supreme court ruling on parking space says that the builder or the promoter has no right to sell stilt parking spaces as these are neither flat nor appurtenant or attachment to a flat,
In your case the builder has cleverly sold the parking space for an amount without showing this parking space separately in the registered sale deed, therefore he can absolve himself from the liabilities even if you approach court.
His oral promises will not stand a ground against him in the court of law.
The cost of parking for residential and commercial units is often passed on to the occupants indirectly through the rent or purchase price ("bundled") rather than directly through a separate charge.
Supreme Court has ruled out only the option of buying and selling parking separately as real-estate. It has not ruled out other options.
The Supreme Court ruling means that the developers of residential apartments or commercial buildings must hand the parking areas over to the management organisation (such as the 'housing society'
As you have purchased the parking by a sale deed, it becomes your own private property like the flat, whereas you are actually entitled for a parking in the open parking space too and you can claim rights for parking your car, but it can be after a society is formed. If the management committee of the society is refusing or not inclining to your request you may resort to legal action.
Now you may not have any action against the builder because at this stage he may, due to your pressure may manipulate the parking space and allot you another one which may have some other draw backs too.
But for any legal action against the builder on this, you have to consider all the technical and legal points as per the recital in the registered sale deed in this regard for initiating any action to get a relief on this. .
