We are muslims . My mom has self acquired property in her name. Even my father had some property. To avoid future liltigations , my mom and dad jointly executed will in favour of me and my brothers. My mom is alive. My sisters are objecting will . The will was executed when we all ( children ) were minor and registered. One of my brother is dead. My sisters are frightening us ( sons ) that they will fight for and get the share. They want equal share in property. Though my mom and myself got my sisters married in good places. They are not open for mutual agreement. Please suggest what to do. They want share in my mothers property as well as fathers property equally and nothing else. Please advice. Can my mom appeal in the court of law for justice and settle the issue. What does muslim law say? What does Quran say ?
