In Kenya, the legality of polygamy is not universal but depends strictly on the type of marriage contracted, as defined by the Marriage Act 2014. While some unions permit multiple spouses, others are strictly monogamous.
- Christian, civil, and Hindu marriages are exclusively monogamous.
- Customary and Islamic marriages are presumed to be polygamous or potentially polygamous.
- Bigamy, contracting a subsequent marriage while in a monogamous union, can lead to a void marriage and up to five years' imprisonment for the offense of bigamy.
