It is highly unfair to discriminate against any human being but some culture, some customs and societies outlaw equal rights between the free born man and his counterpart woman. Various researches and studies show that majority of African societies discriminate against women particularly in the area of devolution of demised property of either their father or their husband under the customary law of inheritance succession and the practice of primogeniture. That is inheritance by son heirs. Hence, the main focus of this article is the right of African women to inherit their father and their husband in the present dispensation of modern development where women are the anchor of many successes in all fields of endeavours including domestic affairs of their various homes. Another area of concern to this work is the S42 (2) of the 1999 Constitution of Federal Republic Nigeria (as amended in 2011) which removes stigmatization and discrimination against any Nigerian citizen. This discrimination against women and new development from the judicial decisions with particular reference to declaration of rights of women to inherit the estates of their husbands and their fathers under various customary laws shall be discussed in the body of this work.
