Anti-marriage constitutional amendment


State advocacy groups are working toward fairness for all of Montana's families by overturning a constitutional amendment that prohibits the freedom to marry for same-sex couples in the state.


In 2004, anti-gay forces in Montana pushed through Initiative 96, a constitutional amendment that excluded same-sex couples from marriage. 

In 2009, a domestic partnership bill was proposed in the state legislature, but it was unsuccessful. In July 2010, seven same-sex couples from Montana filed a lawsuit seeking full partnership protections in the state.

A majority of voters in Montana have moved to support marriage, with 46% saying it should be legal, including 47% of independents. (Montana State University-Billings, March 2014)


According to The Williams Institute's analysis of the 2010 U.S. Census, 1,348 same-sex couples are living in Montana, representing 3.3 same-sex couples per 1,000 households.
