Colorado Might Ban All Underage Marriages—No Exceptions.

The Bottom Line

Colorado is tightening its family laws to protect teenagers from potential exploitation. This policy explicitly bans 16- and 17-year-olds from marrying anyone who is 10 or more years older than them, closing a loophole that previously allowed extreme age-gap unions with a judge's permission.

What This Bill Actually Does

Under current Colorado law, you generally have to be 18 years old to get a marriage license. However, there has long been a significant exception on the books: 16- and 17-year-olds can legally tie the knot if they obtain judicial approval. To get that approval, a judge must appoint a guardian ad litem—an independent, court-appointed legal advocate—to investigate the situation and ensure the minor isn't being coerced and that the marriage is genuinely in their best interest.

Senate Bill 26-048 originally took a zero-tolerance approach to this issue, attempting to wipe out the judicial exception entirely and make 18 the strict minimum age for everyone. Lawmakers debated this heavily, balancing the desire to protect minors against the reality that some older teenagers—such as high school sweethearts or young expecting parents—might have valid, safe reasons to marry with court oversight. Ultimately, the legislation was amended to target the most concerning scenarios: extreme age gaps.

Under the refined policy, 16- and 17-year-olds can still seek judicial approval to marry, but only if the age difference between the minor and the adult is less than 10 years. If the gap is 10 years or greater, the state will automatically deny the application—no judicial override allowed. Furthermore, the bill upgrades the legal penalty for violating this rule. If a marriage somehow slips through in violation of these age limits, the union isn't just considered "voidable" (meaning it can be annulled later); it is completely void from the very beginning, legally treated as if it never happened.

What It Means for You

If you are a parent, a teenager, or just a Colorado resident keeping an eye on family law, the primary takeaway is that the state is raising the guardrails around underage marriage. While the vast majority of Coloradans wait until adulthood to get married, the state has historically recognized that some older teens might have legitimate reasons to marry—such as an impending military deployment or starting a family early. This bill preserves that pathway for couples close in age but completely shuts the door on scenarios that raise serious red flags for coercion or exploitation.

To understand the real-world impact of this policy, we have to look at the numbers. The Colorado Department of Public Health and Environment tracked this exact data and found that a minor marrying someone 10 or more years older happened just five times between 2019 and 2026. While that number is astonishingly low, child protection advocates argue that even one instance is one too many. For those few vulnerable teenagers, this law removes the possibility of being legally bound to a much older adult, taking the option off the table entirely.

In terms of practical logistics, the enforcement mechanism rests directly on the shoulders of your local county clerk and recorder. If an underage resident applies for a marriage license, the standard $30 fee and age verification process remains in place. However, clerks are legally required to calculate the exact age difference before moving forward. If the gap hits the 10-year mark, the application is rejected on the spot. This saves families the time, emotional stress, and legal fees of petitioning a court that is now legally barred from approving the union.

What It Means for Your Business

Let's cut right to the chase: unless you operate in a very specific niche of family law or local government, this bill will not require you to overhaul your business operations. There are no sweeping employer mandates, no new payroll taxes, and no complex safety protocols to implement. If you run a construction firm, a restaurant, or a retail shop, this legislative update will pass by without creating a single ripple in your day-to-day workflow. The direct economic footprint is limited purely to the procedural mechanisms of the state court system.

However, the landscape looks a bit different if you operate within the legal or government sectors. Family law practitioners, mediators, and court-appointed advocates will need to update their internal guidelines and client intake processes. If an underage client seeks representation to petition for marriage, your firm must immediately verify the age gap before taking a retainer or filing paperwork. Similarly, county government offices must ensure their front-desk staff are trained to enforce this strict 10-year cutoff during the standard marriage license application process.

For the broader business community, this serves as a helpful prompt to review your human resources policies regarding spousal benefits and age verification. While statistically rare—with only five such marriages occurring in a seven-year span across the entire state—Colorado employers must still legally recognize valid underage marriages when administering health insurance, survivor benefits, and leave policies. Ensuring your HR software and compliance manuals accurately reflect state marriage definitions is always a smart, evergreen practice, even as the state actively works to make extreme age-gap underage marriages a thing of the past.

Follow the Money

When we look at the state ledger, the fiscal impact of this bill is essentially a rounding error. Because the state is only preventing a tiny fraction of marriages—less than one per year on average—the corresponding drop in state revenue is practically invisible. Currently, the standard marriage license fee in Colorado is $30. That fee is split three ways: the local county retains $7, while the state collects the remaining $23.

That state revenue is further divided, with $3 flowing into the Vital Statistics Records Cash Fund and $20 going directly to the Colorado Domestic Abuse Program Fund. Losing a couple of these fees over an entire decade will not impact the funding, staffing, or operations of these state programs. On the expenditure side, the Judicial Department and the Office of the Child's Representative will actually save a tiny fraction of administrative time. By banning these specific extreme age-gap marriages outright, the courts avoid the expenses associated with holding special hearings and appointing guardians ad litem, meaning this policy requires absolutely zero new tax dollars to enforce.

Where This Bill Stands

SB26-048 is currently In Committee. The latest official action came on 05/13/2026: Senate Considered House Amendments - Result was to Concur - Not Repassed.

That means the bill is still in the committee stage, and it is currently sitting in the State, Veterans, & Military Affairs. To keep moving, it would need to clear committee and then survive floor votes in both chambers.
