A couple in Colorado can be legally married without a wedding ceremony or marriage license. That may surprise people who assume a marriage certificate is the only way to become spouses. Colorado is one of the states that still recognizes common-law marriage, but a shared address or a long relationship is not enough to create one.
Colorado is also a common-law legal-system state, meaning its courts apply judicial precedent alongside legislation. In property matters, however, it is not a community-property state. Courts generally divide marital assets fairly, rather than automatically awarding each spouse half.
For partners in Denver, Colorado Springs, or elsewhere in the state, these distinctions affect whether a marriage exists, who may inherit, and what happens when a relationship ends. Understanding the evidence of marriage is particularly important because a valid common-law marriage has the same legal force as a ceremonial one.
Understanding Colorado’s Common-Law Legal System
Colorado follows the American common-law tradition, which developed from English law. Courts interpret written statutes and use precedent—rulings from earlier cases—to decide similar legal disputes. Decisions of higher courts can bind lower courts.
Colorado Revised Statutes (C.R.S.) § 2-4-211 adopts applicable English common law as a rule of decision until changed by legislative authority. This does not mean old English rules always control. Federal and state constitutions, current legislation, and controlling Colorado court decisions shape modern law.
Three terms are worth separating: a common-law legal system describes how law is developed; common-law marriage describes a legally recognized marital relationship formed without the standard ceremony; and common-law property usually refers to separate ownership rather than community-property rules.
Colorado’s unusual position is that it follows common-law principles and allows couples to establish common-law marriages within the state.
Is Colorado a Common-Law Marriage State?
Yes. Colorado continues to recognize new common-law marriages. These marriages do not require a marriage license or a formal ceremony, but they do require more than cohabitation. Both people must genuinely agree to enter the legal and social institution of marriage and behave in ways that demonstrate that agreement.
In In re Marriage of Hogsett & Neale (2021), the Colorado Supreme Court updated the test for proving a common-law marriage. Its focus is the couple’s mutual intention to be married, followed by conduct showing that intention. Courts look at the entire relationship, not a checklist or a single document.
What Evidence Can Establish a Common-Law Marriage?
Useful evidence may include:
- Mutual agreement: Statements or actions showing that both partners considered themselves married, not simply committed to a future wedding.
- Conduct showing marital commitment: How the couple arranged their shared life and responsibilities.
- Public and private representations: Describing each other as spouses on suitable documents or to people who know them.
- Financial records: Joint ownership, shared accounts, or other arrangements consistent with a marital relationship.
- Other circumstances: Testimony, correspondence, and conduct that help show what both partners intended.
No one factor is decisive. A joint mortgage does not automatically establish marriage, while separate bank accounts do not necessarily disprove it. The court warned against assuming all married couples behave in the same way.
There is no seven-year rule. A long relationship alone does not create marriage, and Colorado law does not impose a minimum cohabitation period.
Are There Age and Eligibility Requirements?
Under C.R.S. § 14-2-109.5, a common-law marriage entered into on or after September 1, 2006, requires both people to be at least 18 and the marriage not to violate Colorado’s prohibited-marriage rules. An existing marriage to someone else, for example, presents a legal barrier.
Colorado’s common-law marriage protections apply to qualifying same-sex and different-sex couples. In its 2021 decisions, the Colorado Supreme Court also recognized that same-sex couples may have established a common-law marriage before the state permitted them to marry formally.
How Does Colorado Recognize an Existing Common-Law Marriage?
A valid Colorado common-law marriage is a marriage—not a temporary partnership. Spouses may have rights involving inheritance, benefits, and marital property. If they separate, they generally need a legal divorce to end the marriage.
A dispute may arise during divorce proceedings, after a partner’s death, or when benefits are claimed. Courts then examine the evidence and determine whether and when the marriage began. Because there is usually no wedding certificate, keeping clear records can be especially important.
Is Colorado a Common-Law Property State?
Yes, in the separate-property sense. Colorado is not a community-property state. Simply getting married does not automatically place every asset into an equally owned community-property estate. Ownership, the time of acquisition, and the source of funds still matter.
But property rights at divorce are different. Under C.R.S. § 14-10-113, a judge generally sets aside each spouse’s separate property and divides marital property equitably. Equitable means fair under the circumstances—not necessarily 50/50.
Which Assets Count as Marital Property?
Property acquired during a marriage is generally presumed to be marital unless a statutory exception applies. Gifts and inheritances received by one spouse, qualifying property exchanged for separate assets, and property covered by valid agreements can be treated differently.
Colorado has an important twist: an increase in the value of separate property during marriage can be marital property under § 14-10-113(4). For instance, a home owned before marriage may remain separate, but appreciation occurring during the marriage may be considered for division. Valuation and tracing are often essential.
When dividing the marital estate, courts consider each spouse’s contributions, including homemaking, their economic circumstances, and other factors listed in the statute. A person whose common-law marriage is legally established generally enters this same divorce-property framework.
Key Takeaways and Estate Planning Tips
- Clarify your marital intentions. Couples who want—or do not want—to be married should avoid conflicting statements and records.
- Keep evidence. Save relevant property documents, financial records, and other information that could establish when a marriage began.
- Plan property ownership. Consider written agreements and keep records of assets owned before marriage.
- Update estate documents. Wills, beneficiary designations, and powers of attorney can prevent uncertainty.
- Seek guidance early. A Colorado family-law attorney can help when marital status or asset classification is disputed.
Conclusion
Colorado is both a common-law legal-system state and a common-law marriage state. Couples may establish marriage without a ceremony, but only when the legal requirements are met. Colorado follows separate-property principles and uses equitable division in divorce.
Frequently Asked Questions
Q1. Can You Enter a Common-Law Marriage in Colorado Today?
Yes. Eligible adults can establish one through mutual agreement to be married and conduct reflecting that agreement. A ceremony or license is not required.
Q2. How Many Years Must You Live Together to Be Common-Law Married in Colorado?
There is no required number of years. Living together for seven years—or longer—does not prove a marriage without the necessary mutual intent and conduct.
Q3. How Is Property Divided When a Colorado Common-Law Marriage Ends?
Once a valid marriage is established, ordinary divorce property rules apply. The court generally protects separate property and divides marital property equitably, which is not always an equal split.
