How to get my share in my parents property after their death

Currently my brother and his wife not giving my share in my parents property. Instead they are threating me, that to file harashment police complaint. In this regard i have already been to police station twice. In police station she was nit talking actual problem, instead she was telling i am attaking her with help of gundas. She is using women right illigaly. Local people were also talking in her favor. Property is in my mother name, this is what i know few years back. Please guide to what can be done here? What is the legal step i can take and how? Can my wife fight the case on my absence? From the last 12 years, tgey are only using full property. My mother died last year.
