In Ghana, polygyny (a man having multiple wives) is legal under customary law but not recognized under statutory law. This dual system means the practice persists in some communities while the formal legal system promotes monogamy.
Under customary law, a man may take additional wives if he obtains the consent of his first wife and fulfills traditional obligations.
Polygyny has declined due to legal reforms, urbanization, and changing attitudes. A 2010 Demographic and Health Survey found about 7% of married Ghanaian women in polygamous unions, primarily in rural areas and among certain ethnic groups.
Arguments continue between those viewing polygyny as cultural heritage and those seeing it as gender-discriminatory. The tension reflects Ghana's broader negotiation between tradition and modern human rights standards.
