Advice for Further Action

My name is Deepak Kumar Sinha. We are 4 brothers, 3 of them have passed away. On our ancestral land, at the centre of the city near Post Office, dispute is going on regarding property. The land is straight, including 5 shops ( 4 on the same land and other on little away from the plot). It is our father's land and currently registered in the name of my big brother and ourselves. One brother and his family resided here for 34 years, illegally sold many ancestral lands, gave nothing like literally nothing including production from land, rent of shops, etc... We visited regularly but they pretended that they are poor or so and each and everytime each one of us helped financially. In 2002, on stamp paper partition has happened in which front of the land that has 4 shops has been given to the brother's family that resided here. After that my portion or share was allocated and so on . The fact is it was not registered at that time and it was mere on piece of stamp paper including 4 brothers signature. It is written on the paper that Everyone should capture his property within one year but noone captured and my brother enjoyed. Even we paid electricity bill, tax, etc We all agreed, so in Aug 2022 I came and demanded that you should vacant my share and other stakeholders i.e. wives of my big brother (other 2) also came and said the same to the family of brother who resided here in Gopalganj. Raunak who is the son of my brother abused, and said kisi ko kuch nhi denge Jo karna hai kar lijiye. Later through S.P one meeting was conducted and DSP said that come and live in your portion. In Nov 2022. I came with my family but nothing was vacant and he gave only 1 room in the corner . Then , again I went to the police but did nothing much and refered to CO. CO also conducted multiple meetings and at last he said your paper is not registered so I can't do anything. In Oct 2023, I filed a Partition suit in the court. My advocate said previous partition paper i.e. stamp paper is of no legal evidence and new partition through court would happen. In mean time before filing partition suit, he autonomously constructed his house in his share and even extended to my share as well that was allocated in the stamp paper. It was all done without any partition and everyone opposed it as well, police came and warned them , officers from Nagar Parishad also came that how you can come and built home without proper papers and land is not in his name, he did not have any naksha also . In the court, court sent notice multiple times to him but he never responded. Now statement of me and wive of my one big brother is to be recorded in the court. On 3 May, he came to our room and dining space and fighted, abused damaged the home. We went to police and he played victim card by saying I beated his sister, it is all rubbish and false. He is saying to take case away from court..what should I do?
