We & our neighbour share a particular survey sy no. through it HT power line is being laid. Though the extents are clearly mentioned in RTC, we have joint katha. So to receive (joint) compensation, my neighbour and village panchayat member have convinced my father to sign on a paper with an oral assurance that the compensation amount would be shared proportionately after getting it. They have latter converted the signed paper into an affidavit that my father has given consented for making the (joint) compensation to our neighbour's bank a/c. Now after receiving the compensation our neighbour isn't willing to share our part of the compensation. Instead all of a sudden he is challenging the boundary of our possession. As the HT power line is impairing most of our land, compensation is also swindled by our neighbour and moreover creating a faux boundary litigation. What are the legal provisions available for us to claim our compensation share and defend our land?
