This article studied the effects of common law in Sub-Saharan Africa on property rights of women and its relationship to intimate partner violence. The authors first compared intimate partner violence (IPV) in 593 ethnic groups with a separate marital property regime against groups with a community marital property regime. Then, the authors examined the correlation between women who justify IPV and the presence of a separate marital property regime. They found that separate marital property both increased the likelihood of intimate partner violence and the justification of IPV when compared to a community property regime. The authors use these findings to advocate for marital property rights reform to help reduce partner violence cases.
