This study uses individual-level survey data from women and men in Uganda and South Africa to examine coupled women's joint ownership of land and housing. It compares women's control over and benefits from jointly held land and housing with those of coupled women not owning land or housing at all and coupled women owning them solely. The lack of a clear and consistent advantage of joint ownership potentially arises from frequent disagreement within couples about whether the land or house is jointly owned. The study serves as a reminder of the complexities of joint ownership in practice, particularly within families, that need to be considered in order for coupled women to benefit from joint asset ownership. Efforts promoting joint ownership, for example, joint titling and marital property laws supporting joint ownership, should not only consider these complexities but also establish and communicate clear and enforceable rules for joint ownership.
