Care taker in a flat

The first thing to do is to check your title certificate and/or conveyance deeds to confirm that there is an easement and to check the terms of your right of way. With luck (but this is not always the case) there will be an accurate descripttion of the extent, shape and form of the right of way, and a statement of who is responsible for its maintenance.

Next, consider whether your rights are being infringed and the amount of inconvenience you are suffering. Try talking to your neighbour to find out what his point of view is and then see if you can negotiate a settlement that accommodates both your needs.

If this fails, or if your neighbour is unapproachable in the first instance, and you need professional help, then consider what your needs are before seeking the appropriate professional help:

Otherwise file a petition for grant of easement for your flat in the local civil courts. 

Yes, a civil action lies in the matter. However, before rushing to the Court you may serve  a Lawyer  Notice on the persons concerned..

Well advised by experts, I agree.

However, is there any formal association of residents in the apartments where you are residing with other 5 persons? If so, are you also a member and paying your contribution of the association?
