Colorado was the 25th U.S. state to legalize same-sex marriage. In 2024, voters repealed the state's constitutional ban on same-sex marriages by 64–36 percent.[4][5]
Civil unions have been legal in Colorado since May 1, 2013. Legislation to establish civil unions was passed in the Colorado Senate by 21 votes to 14 on February 11, 2013, and by the House of Representatives on March 12 in a 39–26 vote. Governor John Hickenlooper signed the bill into law on March 21, and the law took effect on May 1. Civil unions, open to both same-sex and opposite-sex couples, provide rights comparable to those enjoyed by married couples, including spousal employer benefits, presumption of paternity, adoption, next of kin rights, and inheritance, among others. However, as the federal government does not recognize civil unions, partners in a civil union cannot receive federal benefits.
Same-sex marriage
Statute
In 1996, the Colorado General Assembly passed a bill banning same-sex marriage, but it was vetoed by Governor Roy Romer.[6] In 1997, the General Assembly again passed a bill banning same-sex marriage, but it was again vetoed by Governor Romer.[7] In 2000, Governor Bill Owens signed a bill banning same-sex marriage into law.[8]
Following the U.S. Supreme Court's decision in Dobbs v. Jackson Women's Health Organization, which overturned Roe v. Wade, in June 2022, some lawmakers announced they would push to codify same-sex marriage in state statutes and place a measure on the ballot to repeal the constitutional amendment banning same-sex marriage. Governor Jared Polis said he would sign such bills into law.[11] In January 2023, Senator Jessie Danielson said, "The legislature has an obligation to do away with that ban to show the communities that we care about (them), that we're gonna stand up and protect them." A constitutional amendment requires a two-thirds majority in both chambers of the General Assembly.[12] In July 2023, a ballot initiative was filed to amend the Constitution of Colorado to remove verbiage limiting marriage to "one man and one woman", thereby removing the constitutional prohibition of same-sex marriage if passed.[13] In April 2024, Senator Joann Ginal and representatives Alex Valdez and Brianna Titone introduced a constitutional amendment to the General Assembly to refer the issue to voters. The Senate approved the measure 29–5 on April 29,[14] with six Republicans joining all Democrats in support. The House followed 46–14 on May 4, with one Democrat joining Republicans in voting against and two Republicans joining the remaining Democrats in support. The bill was signed by Governor Polis on May 8.[15] In September 2024, a group of religious leaders expressed their support for the measure.[16] As Amendment J, it was placed on the November 5, 2024 ballot,[a] and approved by 64.3% of voters and a majority of counties.[17] Support reached 80% in four counties: Pitkin (84%), Boulder (83%), Denver (82%), and San Miguel (82%). Opposition to the amendment was highest in Cheyenne (79%), Kiowa (78%) and Baca (78%) counties.[18]
In 1975, Clela Rorex, the Boulder County Clerk, became the first county clerk in the nation to issue marriage licenses to same-sex couples.[19] She issued marriage licenses to six same-sex couples after the local district attorney interpreted Colorado's statutes, which used the phrase "any two persons", to be gender-neutral with respect to marriage. Attorney General J.D. MacFarlane issued a contrary opinion that those marriages were invalid, and the licenses were revoked.[20] Dave McCord and Dave Zamora were the first couple to receive a marriage license in Boulder on March 26, 1975.[21]
After being denied a marriage license, a lesbian couple filed a lawsuit on October 30, 2013 in state district court. The case, Brinkman v. Long, sought to overturn the state's constitutional ban on same-sex marriage.[24][25] The couple was joined by nine other same-sex couples who filed a lawsuit, McDaniel-Miccio v. Hickenlooper, also in state district court, seeking the same outcome.[26][27] The suit named Governor John Hickenlooper and a city clerk responsible for licensing marriages as defendants. Attorney General John Suthers announced he would defend the state's ban.[28]
Brinkman and McDaniel-Miccio were combined for argument in state district court. On July 9, 2014, District Court Judge C. Scott Crabtree ruled that Colorado's same-sex marriage ban violated the plaintiffs' guarantees of equal protection and due process under the Fourteenth Amendment to the U.S. Constitution, stating: "No state since United States v. Windsor has been able to justify its ban under even the rational basis test, much less under the strict scrutiny test." The judge stayed his ruling pending the outcome of appeals.[29]
Judge Hartman's decision in Colorado ex rel. Suthers v. Hall provided legal cover for the Boulder County clerk to issue same-sex marriage licenses as a form of civil disobedience. After Hartman's decision was handed down, the Denver and Pueblo county clerks began issuing licenses to couples regardless of gender as well, despite Judge Crabtree's stay. When asked to enjoin the Denver County clerk from issuing licenses to same-sex couples, Judge Crabtree refused to take action. On July 14, 2014, Attorney General Suthers appealed Judge Crabtree's inaction to the Colorado Supreme Court. In a separate filing, and seeking a reversal of Judge Hartman's ruling, Suthers also asked the high court for an emergency injunction to stop all state clerks from issuing licenses.[30][31] On July 18, 2014, the Colorado Supreme Court ordered clerks in Adams and Denver counties to stop issuing marriage licenses. The Supreme Court was scheduled to hear oral arguments regarding the merits of the state's same-sex marriage ban on September 30, 2014.[32]
Burns v. Hickenlooper was a same-sex marriage case filed on July 1, 2014 in the U.S. District Court for the District of Colorado. The plaintiffs were six same-sex couples who had been legally married in another state but whose marriage Colorado did not legally recognize or who had been refused a Colorado marriage license.[33] The main defendants, Governor Hickenlooper and Attorney General Suthers, agreed with the plaintiffs insofar as having the court issue an injunction declaring the same-sex marriage ban unconstitutional, but they wanted a stay and swift resolution by the U.S. Supreme Court in order to avoid costly litigation.[34]
U.S. District Judge Raymond P. Moore found in favor of the plaintiffs in Burns on July 23, 2014, granting their motion for a preliminary injunction. In his ruling, Judge Moore noticed a split among the state defendants even though they agreed with the plaintiffs' motion: "Defendant Attorney General believed Kitchen [v. Herbert] was incorrect while Defendant Governor believed Kitchen was correctly decided. ... Nevertheless, the defendants collectively did not oppose the entry of a preliminary injunction, but also asked that the injunction, as well as further proceedings in this matter, be stayed." After finding that the plaintiffs met their burden for an injunction, he rejected the defendants' request for a stay. Immediately after Judge Moore's order was issued, state defendants filed a notice of appeal and asked the Tenth Circuit Court of Appeals for a stay. The appeals court granted the stay on August 21, 2014.[35][36]
When the U.S. Supreme Court dismissed requests to hear appeals from similar cases from the Tenth Circuit on October 6, Attorney General Suthers asked the Tenth Circuit to lift the stay in this case as well, which would allow the district court's order that Colorado recognize same-sex marriages to take effect.[37] On October 7, the Colorado Supreme Court removed the legal obstacles preventing Colorado's county clerks from issuing marriage licenses to same-sex couples, legalizing same-sex marriage in the state.[3]
Hillary Hall, the Boulder County Clerk, had been issuing licenses based on her own interpretation of the Tenth Circuit ruling in Kitchen soon after that ruling was handed down. Attorney General Suthers filed a motion in state district court in an attempt to stay the clerk's actions. However, on July 10, 2014, a day after the Brinkman ruling, District Court Judge Andrew Hartman found that while Hall violated the law—"There is little argument that Clerk Hall is engaging in a form of civil disobedience. She apparently is taking the position posited by St. Augustine and followed notably by Martin Luther King Jr. that, 'an unjust law is no law at all.'"—but he refused to impose a restraining order or injunction upon her, as the state did not meet its high burden for a stay.[38]
On July 21, 2014, Suthers appealed the ruling; in light of the ruling by the Colorado Supreme Court staying license issuance in Adams and Denver counties, he also asked Judge Hartman to reconsider his ruling and stay it. Judge Hartman denied the state's request on July 23. The next day, a three-judge panel of the Colorado Court of Appeals again denied the Attorney General's motion.[39] The Colorado Supreme Court, sua sponte on July 29, decided to hear the case and ordered it transferred and requested the record on appeal to be filed before it by October 20, 2014. The Supreme Court stayed Hall from issuing same-sex marriage licenses in the meantime.[40]
On June 25, 2014, the Tenth Circuit Court of Appeals in the case of Kitchen v. Herbert ruled that Utah's ban on same-sex marriage violated the U.S. Constitution. The ruling in Kitchen is binding on courts in every state within the Circuit, including Colorado. Since the Tenth Circuit stayed implementation of its ruling pending review by the U.S. Supreme Court, courts in Colorado have had to follow the precedent that Kitchen sets and stay subsequent rulings pending the expiration of that stay.[41][42] Immediately following the decision in Kitchen, the Boulder County clerk began issuing marriage licenses despite the stay.[43] After a state district court refused to stop the clerk in Colorado ex rel. Suthers v. Hall, Denver and Pueblo counties began issuing marriage licenses to same-sex couples as well.[44] All Colorado counties stopped issuing marriage licenses following stays issued by the Colorado Supreme Court.
When the U.S. Supreme Court dismissed requests to hear an appeal of the Kitchen case on October 6, Attorney General Suthers asked the Tenth Circuit to lift the stay in this case as it related to Colorado, which would allow the district court's order that Colorado recognize same-sex marriages to take effect.[37] On October 7, the Colorado Supreme Court removed the legal obstacles preventing Colorado's county clerks from issuing marriage licenses to same-sex couples, legalizing same-sex marriage in the state.[3]
Common-law marriage cases
Colorado is one of a small number of states that recognizes common-law marriages. Common-law couples are considered legally married without having registered their relationship as a marriage with the state. Parties in a common-law marriage are entitled to all rights, privileges and responsibilities of a legal and binding marriage. Common-law marriages have been recognized in Colorado since 1887, and in 1987 the Colorado Supreme Court, in People v. Lucero, set out requirements for the existence of a common-law marriage. The decision held that couples' conduct, including cohabitation or taking the partner's surname, as well as their reputation in the community, were "factors that most clearly show an intention to be married".
Dean LaFleur and Timothy Pyfer held a commitment ceremony with family and friends in 2003. After the couple separated, Pyfer filed to dissolve the marriage in January 2018. LaFleur argued that he did not mutually agree to enter into a common-law marriage. A Jefferson County District Court judge ruled in the case of In re Marriage of LaFleur and Pyfer that the couple were common-law married. The court awarded $50,000 of LaFleur's retirement to Pyfer and ordered spousal maintenance. Both parties appealed. On January 11, 2021, the Colorado Supreme Court upheld the marriage of LaFleur and Pyfer, and ruled that, pursuant to the U.S. Supreme Court's decision in Obergefell v. Hodges, same-sex couples must be allowed to enter into common-law marriages and the state must retroactively recognize common-law marriages of same-sex couples that occurred prior to the legalization of same-sex marriage. On the issue of division of property and spousal maintenance, the justices sent the case back to the Jefferson County District Court, ordering further review.[45][46]
Edi Hogsett and Marcia Neale, a couple for thirteen years, separated in January 2015. Hogsett believed the parties were common-law married and petitioned for a dissolution of marriage in Arapahoe County District Court. Neale disagreed and moved to dismiss the petition. A district court judge ruled in the case of In re Marriage of Hogsett and Neale that the couple had not formed a common-law marriage, the Lucero text factors were outdated and granted Neale's motion to dismiss. The Colorado Court of Appeals agreed in December 2018 with the lower court's finding, and noted that pursuant to Obergefell v. Hodges the Lucero factors should be updated. On January 11, 2021, the Colorado Supreme Court agreed. The court noted that the test must be applied flexibly to the facts of each case, explaining that same-sex couples may not be fully open about their relationships due to fears of discrimination and thus may only discuss their relationship with a close community, and prior to the legalization of same-sex marriage, same-sex couples could not file joint taxes or refer to themselves as married on government forms.[45][47]
Developments after legalization
On June 26, 2015, the U.S. Supreme Court ruled in Obergefell v. Hodges that the Due Process and Equal Protection clauses of the Fourteenth Amendment guarantee same-sex couples the right to marry. The ruling legalized same-sex marriage nationwide in the United States.
On February 3, 2020, four Republican lawmakers introduced a bill to the General Assembly to ban same-sex marriage. Republican leaders quickly distanced themselves from the proposal. Rob Witwer, member of the House of Representatives between 2005 and 2009, said in an interview, "It's a needless provocation and a waste of people's time. The only thing it serves to do is polarize people over an issue that's by-and-large been settled and that public opinion polls show people have accepted." House Minority Leader Patrick Neville said he was unaware of the bill and "hadn't given much thought to the idea of banning gay marriage". Leslie Herod, a member of the Democratic Party, said, "I'll be damned if this bill, these bills, try to take away the rights of my family, the rights of my friends, and the rights of my community, period." The measure was voted down in a marathon hearing in a House committee that stretched into the early hours of February 15, 2020.[48]
Colorado is home to two Native American tribes: the Southern Ute Indian Tribe and the Ute Mountain Ute Tribe. Same-sex marriages are performed in the latter under federal law. The Bureau of Indian Affairs operates courts established throughout the U.S. under the Code of Federal Regulations (CFR), and "until such time as a particular Indian tribe establishes their own tribal court, the Court of Indian Offenses will act as a tribe's judicial system".[50] Same-sex marriages for Ute Mountain Ute tribal members can thus be performed in these federal CFR courts. The Southern Ute Indian Tribe is not under the jurisdiction of the CFR courts; however, it is unknown if same-sex marriage is legal on its reservation as the tribe has not published its tribal code nor has publicly commented on the issue.
While there are no records of same-sex marriages as understood from a Western perspective being performed in Native American cultures, there is evidence for identities and behaviours that may be placed on the LGBT spectrum. Many of these cultures recognized two-spirit individuals who were born male but wore women's clothing and performed everyday household work and artistic handiwork which were regarded as belonging to the feminine sphere.[51] The Ute people refer to two-spirit individuals as tuwasawich (pronounced[tuˈwasawitʃ]).[52] Traditionally, the tuwasawich could marry men or women, while some remained unmarried.[51] This two-spirit status thus allowed for marriages between two biological males to be performed in the tribe.
Demographics and marriage statistics
Data from the 2000 U.S. census showed that 10,045 same-sex couples were living in Colorado. By 2005, this had increased to 15,915 couples, likely attributed to same-sex couples' growing willingness to disclose their partnerships on government surveys. Same-sex couples lived in all counties of the state, except Cheyenne and Hinsdale, and constituted 1.1% of coupled households and 0.6% of all households in the state. Most couples lived in Denver, Jefferson and Arapahoe counties, and the counties with the highest percentage of same-sex couples were Denver (1.22% of all county households) and Gilpin (1.13%). Same-sex partners in Colorado were on average younger than opposite-sex partners, and more likely to be employed. In addition, the average and median household incomes of same-sex couples were higher than different-sex couples, but same-sex couples were far less likely to own a home than opposite-sex partners. 14% of same-sex couples in Colorado were raising children under the age of 18, with an estimated 4,091 children living in households headed by same-sex couples in 2005.[53]
The 2020 U.S. census showed that there were 14,148 married same-sex couple households (5,978 male couples and 8,170 female couples) and 10,414 unmarried same-sex couple households in Colorado.[54]
