Fatwa #216530 January 2001United States of America
Does an illegitimate child inherit from the Estate of his/her father/mother?
Answer
According to the Shari'ah, an illegitimate child will be attributed only to the mother. (Shaami vol.23 pg.489; HM Saeed). Therefore, the child will
inherit from the mother only. The biological father may make a bequest
(maximum of one third of the estate after funeral expenses and debts) in
favour of his illegitimate child.
