Hi
In a muslim inheritance , the children cannot claim the share of father's property in the following conditions:
a) Children who had attempted to murder their father/Mother or
b) got married to a girl from different religion or
c) openly claimed in front of the Qazi that he had disowned the father OR
d) The father has disowned the son in front of qazi and the same being recorded in the records or
e) If the son is addicted to vices prohibited in the Quran.
In absence of any of the above, the common practice amongst muslims is to first divide the shares equally amongst the son and daughter.
Hope this helps
