Who can I solve land dispute

Dear Sir, I am Somiya Menon my address is Rania Gita Nagar , PO -Boral , PS - Sonarpur , and district - south 24 pargana . West Bengal - 700154 . With due respect I would like to inform you that I belong from a lower middle class family and my and my parents only asset is our land which has been constructed by my father investing his whole life savings. But now this only asset of my family is in trouble and in a situation to get destroyed or ruined. From my childhood I know that our area (Rania) has a land dispute. And several land survey happened by Local surveyor ( amin) for so many times ( at least 10 times) for the land including our land ( our residential house also their) . Each time there we found different different solution several times my area comes under my neighbor's area or vies verse . It's increase local tension . Basically we are non political . Actually what happened each time if my area comes in their place they fight with us and if there area comes in our land then they pressure us to break our house . Till date we could not able to protest because my father is very introvert type of person and afraid from such kind of clash as these people are basically rowdy type. Till date it's continues like this. I know due to jealousy this people are doing this. They want to crock our land . I want to know how we can survive in this social condition. How can I save my parents, to whom I complain .I am every time afraid about my parents thinking mishaps . They are now mentally and physically broken . My father is always worried how he will run my studies as I am only a student of B. Com Honours 1st year and how will he save his only life time asset . As I have already mentioned that we belong from a poor middle class family we can't afford the charges of heiring a lawyer or bearing the expenses of legal formalities . Even though I have faith on Indian law they may provide me justice though I belong from poor family . Please help me to show a way . As I think that a poor family has also right to get justice . Please help me to bell the cat .
