Title 6 of the Tribal Code, titled "Family Relations of the Sac & Fox Tribe of the Mississippi in Iowa", as updated on 30 August 2017, states in Section 6–1203(c), "Same-gender marriages prohibited. Only persons of the opposite gender may marry." However, under Section 6-1205(a) it says, "all marriages performed other than as provided for in this Code, which are valid under the laws of the jurisdiction where and when performed, are valid within the jurisdiction of the Sac & Fox of the Mississippi in Iowa."
