Want justice for my mother

Hi experts I am asking on behalf of my mother aged 72 years. My brother is not taking care of my mother since his marriage I.e. 2000 I was unmarried at that time and working to earn for our livelihood. I was got married in year 2004 my mother alone did everything and my brother not supported for anything in my marriage. Before 1 month of my marriage my brother came in drunk and started fighting with my mother and taken the paper of our house with him and threatened that I will come everyday like this if you won't come with me to make the property in my name. Forcefully he had taken my mother's with him at that time as my mother is illiterate she don't know what he has done. Since my marriage I am living in a rented house with my husband near my mother's house to take care of her. But my brother never done anything for her but he and his wife came time to time to ask my mother to get out of the house. Now I mother has been diagnosed with sewer liver disease and need money for the treatment and she want her property back from him. House is so old and has no facility and sewage water from naali outside get filled and she has to collect it and throw outside from the house. Please help to get justice. Regard Shashi
