How can I go about getting property that my grandparents left to me and my brothers parent.

My grandparents have three houses one was left to my brother and one was left to my other brother and one was left to me I got incarcerated for 4 years and when I got out I had nothing nowhere to go my grandparents passed on I have the will . My younger brother who took over everything kept the houses and now he's passed on he didn't allow me to get my house or nothing because I didn't know how to go about it but I do have the legal will I lived there all my life but now it's my younger brother's kids just living there and he's passed on and it's only me and my little brother that are left
