Sub-section 3 to 6 of section 4 of the Delhi Apartment Ownership act will provide you the relief , the same is reproduced below:
(3) Every person who becomes entitled to the exclusive ownership and possession of an apartment under sub section (1) or sub section (2) shall be entitled to such percentage of undivided interest in the common areas and facilities may be specified in the Deed of Apartment and such percentage shall be computed by taking, as a basis, the value of the apartment in relation to the value of the property.
(4) (a) The percentage of the undivided interest of each apartment owner in the common areas and facilities shall have a permanent character, and shall not be altered without the written consent of all the apartment owners.
(b) He percentage of the undivided interest in the common areas and facilities shall not be separated from the apartment to which it appertains and shall be deemed to be conveyed or encumbered with the apartment, even though such interest is not expressly mentioned in the conveyance or other instrument.
(5) The common areas and facilities shall remain undivided and no apartment owner or any other person shall bring any action for partition or division of any part thereof, and any covenant to the contrary shall be void.
(6) Each apartment owner may use the common areas and facilities in accordance with the purposes for which they are intended without hindering or encroaching upon the lawful rights of the other apartments owners.
From the above the subsection 6 will be more aptly suitable. If your neighbor is hindering or causing you disturbance and not listening or paying heed to your request, you may issue him a legal notice with a copy endorsed to the secretary of the association demanding him to oblige and respect the law as well as honour other's rights in the common space.
