What is the plan of action I should have?

Hindu Family... I'm a widow, I was staying with my mother and daughter. After my mother's death, my sisters came with a will deed and pulled us out from there. Physically injured me and didn't let us go inside. All my things, clothes, money, documents, evidence that could be used in court, remained inside. What should be done? They have tied up with local police and lawyers and politician as my sister's husband is a govt employee with the RTO. This happened while a case was already going on in the court against the testator done by one of my sisters so that my mother doesn't sell the property. The will deed they had got it done when my mother had broken her leg. Since I was taking care of her, I took her to hospital, later my sisters came, they asked me to get my mother's medical records from the place she was admitted before, and while I was away, they took her to another city to get her operated and got the will deed done.
