Family deniying me my rightful share because I'm divorced .

Hello Sir/Madam , I'm in need of a legal advise for preventing my family members illegally taking over my share of heriditary assets and properties that are in my name . I'm a divorcee and the mother of a 25 year daughter in a Muslim family .my native is Trivandrum,kerala but now living in Bangalore since my daughter works here. My father passed away recently without writing any will .My mother is a sadist and psychopath who denies me of any wealth claiming that I don't have a husband .She keeps the documents of the property and the gold given to me during my marriage in her custody .My father had assests in different banks .My mother approached these banks but they denied her as I was not present .They said to her that if I cannot come ,I should explicitly sign a letter consenting the bank to transfer my share of money to her. She demands me to give consent to transfer the properties to her. Years back she made me sign in blank papers so Im afraid that she might also use it to acquire my share . I want to send my daughter for higher studies according to her will and hence in need of money .Please help me with legal advice what I should do immediately to prevent them from using fake documents in the bank . I would also like to have a legal advisor (preferably from Trivandrum ) by my side to talk to them in legal terms and come to me with the bank so that I can get what I rightfully own . Please help me [deleted] .
