In 2005, a controversial Kansas marriage case drew national attention after a 14-year-old girl was legally married to a 22-year-old man. The case exposed serious gaps in Kansas marriage laws and raised urgent questions about child marriage, consent, and legal loopholes.
Public outrage over the situation eventually forced lawmakers to step in and change how Kansas handled marriages involving minors.
What Happened In The 2005 Kansas Marriage Case
The case involved a 14-year-old girl named Crystal and Matthew Koso, who was 22 years old at the time. Their relationship reportedly began years earlier, when Crystal was still a young child. By 2005, Crystal was pregnant, and the couple crossed state lines into Kansas to get married.
The marriage took place in May 2005, reportedly in Hiawatha, Kansas. Under Kansas law at the time, the marriage was considered legal because it met the state’s consent requirements—even though the age difference raised serious concerns.
Before the marriage, Crystal’s mother had attempted to stop the relationship and even obtained a restraining order against Koso in 2004.
Despite this, the marriage still went through, highlighting how easily existing safeguards could be bypassed.
Why Kansas Law Allowed The Marriage
In 2005, Kansas did not clearly set a minimum age for marriage in statute. Instead, the law relied on a consent-based system:
- Minors could marry with parental or guardian consent.
- In some cases, judicial approval was required, but not always.
Another controversial part of the law was a marriage-related exception tied to age-of-consent rules. Once married, certain protections that normally applied to minors no longer functioned the same way.
Critics argued this created a dangerous loophole that could be used to shield abusive relationships.
Legal And Criminal Consequences
Although the marriage was legal in Kansas, the situation did not end there. Authorities in Nebraska, where parts of the relationship took place, later charged Matthew Koso with first-degree sexual assault under Nebraska law.
This highlighted how state laws differed sharply, especially regarding the protection of minors.
The case became a powerful example of how crossing state lines could be used to exploit weaker laws in one state while violating stricter laws in another.
How The Case Sparked Legal Change In Kansas
The public reaction to the case was swift and intense. Lawmakers faced growing pressure to close the loopholes that allowed such a young child to marry. In response, Kansas moved to tighten its marriage laws.
The changes introduced after the case included:
- No marriage allowed under age 15
- Age 15 requires approval from a judge, who must determine it is in the minor’s best interest
- Ages 16 and 17 require parental consent, with judicial oversight in special situations
These changes significantly reduced the likelihood of extremely young marriages being approved in Kansas.

Why This Case Still Matters Today
The 2005 Kansas marriage case remains a critical reference point in discussions about child marriage laws in the United States. It showed how outdated statutes could fail to protect children and how legal systems sometimes lag behind social realities.
While Kansas strengthened its rules, advocates continue to push for even stricter protections nationwide, arguing that marriage should never be used to legitimize harm or exploitation.
The marriage of a 14-year-old girl in Kansas in 2005 was legal—but it shocked the public conscience. By exposing weaknesses in the law, the case forced Kansas to confront uncomfortable truths about consent, protection, and responsibility.
The resulting legal reforms marked an important step toward safeguarding minors, proving that even one case can spark lasting change when society demands accountability.
