If there are no other heirs or successors to your deceased father then the property after fulfilling other formalities as per Islamic laws shall be distributed between your mother and you with proportionate share.

Your mother can sell her 50% share in the property without taking consent of NOC from you people and if intends to sell the entire property then as successors you and your siblings have to jointly execute the registered sale deed in favor of the purchaser.

1. Was your father a Shia or Sunni? The rules relating to succession are different. When every a person dies his property is distributed amongst his family.The laws of inheritance are different for sunni and shia. Under both of these sects first the quranic shares are given to father, grandfather, husband, wife, mother and daughter. There is no quranic share for the son. The son always gets twice that of the daughter. So the ratio is 2:1. Under sunni law the male descendants or ascendants are given preference.This means that if the propositus dies leaving behind a daughter and a brother, the daughter would receive her quranic share and the rest of it would got to the brother. In shia law however there is a class system. The people in the first class override those in the second class. The daughter is in the first class and the brother in the second class. So in the same situation the daughter would take everything overriding her uncle.

2. Therefore under the shia sect the male is not given preference. Even the daughter's daughter would outweigh the brother of the deceased. This is the basic difference of how the property is distributed under the two sects.
