It should be noted that if your father only named your mother as the owner of the property and did not give up the possession, then all of this property will be counted as your father's property and will be divided after his death among those considered by Shariah as legal heirs.
After deducting the expenses of funeral and burial, repaying loans, and if he died testate then after executing the will in one third (1/3), the total property will be divided into seventy two(72) parts. The widow of the deceased will get nine (9), each son fourteen (14) and each daughter seven (7).
If division is done according percentage then
For widow - 12.5%
For each son - 19.44%
Each daughter will receive 9.72%.
Note: The five-year rent will be divided in the same proportion among the legal heirs.
