incest (section 9‐1‐5) or bigamy (section 9‐1‐6). Additionally, an opinion by the nation's Assistant Attorney General from May 4, 2016 states that due to its recognition of Mississippi state law (where same-sex marriage has been legal since the Supreme Court ruling in the case of Obergefell v. Hodges) as a "valid means for marriage, same sex marriage is valid in tribal court. Additionally, the tribe will recognize a Mississippi same-sex marriage licence." Furthermore, the tribal court is not prohibited by the current nation's code from issuing same-sex marriage licenses. Northern Cheyenne Tribe The Northern Cheyenne Uniform Marriage and Divorce Act defines marriage as a personal, consensual relationship between a man and a woman arising out of a civil contract and requires at section 8-1-10.D that the parties take each other as husband and wife.

Void and voidable marriages per section 19-1-6 include those within prohibited degrees of consanguinity, those in which a party had a living spouse and those in which a party is incapable of having sexual relations or was forced or coerced.

Section 107 does not require a specific ceremony but the parties must declare in the presence of the officiant that they take each other as husband and wife.
