Suit for grandmother property

Hi sir/ mam, We have a property case between our property and my grandma(father's mother ) . My dad passed away and my grandma denied for share in dad property. My dad's sister and his husband were threatening us for property as my grandma was with them. we went in compromise and gave more than her share . Now my grandma passed away and still my dad's sister and his husband threatening my mom for still property and creating issues in land which is allocated for us after court proceedings.. I heard my dad's sister forced my grand MA to write thana settlement for her and soon after final degree my grandma passed away.. Still they creating issues for us and life threatening myself and mom . I'm married and having kid.. My doubts are 1. Can I put suit for my grandma property which we gave thought court because all suggesting that even after we give her share in dad property I have rights in grandma property 2. And can we get any stay from court against my dad sister and husband from entering our property which is allocated by court proceedings , I guess it is court violation by them
