The trend of violence against women in Nigeria has increased more than ever recently, with many women having been deprived of their fundamental rights. Violence against women in Nigeria includes sexual harassment, physical violence, harmful traditional practices, emotional and psychological violence, and socio-economic violence. This article investigates cases of domestic violence against women in South West Nigeria by assessing the role of family courts in the adjudication of such cases. Both primary and secondary sources of data were employed to examine incidents of violence against women and the role of the family courts in ensuring justice. The author employed both primary and secondary sources of data; the data gathered were analysed by frequency and simple percentages, while qualitative data were descriptively analysed. The article reveals the causes of domestic violence against women to include a cultural belief in male superiority, women’s lack of awareness of their rights, women’s poverty owing to joblessness, men seeking sexual satisfaction by force, women having only male children, the social acceptance of discipline, the failure to punish the perpetrators of violence, the influence of alcohol, and in-laws’ interference in marital relationships. It also reveals the nature of domestic violence against women. The research revealed that the family courts have played prominent roles in protecting and defending the rights of women. The author therefore recommends that the law should strengthen the family courts by extending their power to penalise the perpetrators of violence against women.
