Information on the conditions for LGBT people in Nigeria is well documented.
Homosexual acts between men are punishable by death in 12 states.
Male to male relationships: 14 years of prison
Female to female relationships: 14 years of prison
Nigerian law provides for a 14-year prison sentence for homosexual acts involving either men or women. In addition, a new law, enacted Jan. 7, 2014, for prison sentences of 10 years for Nigerians belonging to a gay organization, supporting same-sex marriages, or displaying same-sex affection in public. It also calls for up to 14 years in prison for any Nigerian who marries a member of the same sex.
In 12 Nigerian states in the north, sharia law also applies. For homosexual activity, that law provides for capital punishment for men, lashing or imprisonment for women.
