Common pathway

, For almost fifteen years the house that we( me with my parents) live in( since bought from previous owner) share a common pathway with the house nearby. The common pathway is used to reach our house from main gate.The site was previously owned by brothers and water tanks, sun roof, water connection, electric connection where all in the common pathway and also over our property. Since we got the house from one of the brothers the other continued to stay in other house. But we found no issue on it so we continued to allow every usage including parking in the common pathway, all pipeline, window, sunroof, wire over our property. Two years back the first house was sold for a second time ( the other brother sold the house and resold by the other user as well) . Now the lady who has currently bought the house is causing nuisance saying that she paid for the whole pathway and it belongs to her.. but according to papers her house is actually only from her said door she doesn't have any right over the common pathway or paid for it. She can use the pathway and no unnecessary additions can be added to it. I need suggestions on if we ask her to remove the underground water tank, electric connection, water connection, sun roofs on both the common pathway and in our property should it be removed immediately? Is it legally allowed to build sunroof, windows opening to our properties, have pipeline connection of water, electric cables and such over our property and having underground water tank, sunroof, windows in common pathway.
