While the federal government treats Native American tribes as sovereign, domestic, dependent nations, federal law trumps tribal law in many matters outside a tribal nation's jurisdiction. This means that any laws enacted by a tribal nation must still align with the federal government's laws and policies.
With regards to same-sex marriage, Native American nations and tribes have the right to allow or prohibit same-sex marriage. Before DOMA was partially overturned by the Supreme Court in June 2013, same-sex marriages were not recognized by the federal government, even if they were valid under tribal law.
But today, if a tribal nation permits same-sex marriage and a couple is married under the laws of their nation, the federal government is required to extend spousal federal benefits, including Social Security disability, to that couple. This is true even if the couple lives in a state that prohibits same-sex marriage.
There are 566 Native American tribal entities recognized by the federal government. Most tribes have remained silent on the issue of same-sex marriage. However, some tribal nations have banned same-sex marriage, some tribal nations have chosen to adopt the laws of the state in which the tribe is located, and others have specifically legalized gay marriage for their members. Here is a list of nations that have stated their positions on same-sex marriage. See the discussion below for when Social Security benefits are available to gay Native Americans who are married under tribal law.
The following tribes permit same-sex marriage. This means that federal spousal benefits, such as Social Security survivor's benefits, are available to same-sex spouses married under the laws of one of these tribes. This is true even if state law in which the tribe is located prohibits same-sex marriage. However, whether or not the state will recognize the marriage depends on the state's laws.

You can read about the law at the National Indian Library website.

Because federally recognized Native American tribal entities are sovereign, they are not bound to the state constitution in which the tribe is located. This includes laws regarding same-sex marriages. This means that the federal government must extend federal spousal benefits to same-sex couples that have a valid marriage under the laws of their tribe who live on tribal lands, even if the couple would not be able to wed in the state where their tribe is located.
Conversely, this means that if your tribe is located in a state that permits same-sex marriage, your tribe is not required to allow same-sex marriages. Check with your tribal government for specific information about how your tribe approaches same-sex marriage.
To be eligible for spousal Social Security benefits, your marriage must be valid in the jurisdiction where you are "domiciled." Your domicile is the place where you permanently live. For example, if you are married under the laws of the Santa Ysabel tribe of California, which permits same-sex marriage, yet live in South Carolina when you apply for Social Security benefits, you will be ineligible, because the laws of South Carolina do not recognize same-sex marriage.
On the other hand, if you are married under the laws of Coquille Tribe of Oregon, for example, and have your legal residence on tribal lands, you will be eligible for spousal Social Security benefits even though Oregon doesn't permit same sex-marriage (as of August 2013). However, if you move off of tribal lands and into the state of Oregon, you will lose your eligibility for Social Security benefits, because Oregon doesn't recognize same-sex marriages, even marriages that are valid under the laws of the jurisdiction where they were performed.
