California has officially closed a long-standing legal loophole that allowed minors to marry, becoming the 18th state in the nation to prohibit child marriage without any exceptions. On September 30, Governor Gavin Newsom signed Assembly Bill 1267 into law, establishing 18 as the minimum age for marriage in the state.
The legislation, authored by Assemblymember Gail Pellerin and sponsored by the advocacy organization Unchained at Last along with the California Commission on the Status of Women and Girls, represents the culmination of nearly a decade of persistent campaigning by survivors and advocacy groups. The new law repeals previous provisions that had permitted minors to marry with parental consent and judicial approval—a system that effectively left California without any statutory minimum marriage age.
Under the old framework, California was one of a dwindling number of states where children could legally wed. The absence of a minimum age threshold meant that minors could enter into marriage if they obtained permission from a parent or guardian and received approval from a judge. The new law eliminates this pathway entirely, while also removing a parallel exception that had allowed minors to enter into domestic partnerships.
The signing ceremony brought survivor voices to the forefront of the conversation, highlighting the personal stories that drove the legislative effort. For years, advocates had argued that allowing minors to marry—even with parental or judicial consent—created conditions ripe for coercion, abuse, and exploitation. Many survivors of child marriage have recounted how the practice trapped them in dangerous situations from which they could not easily escape.
California's journey toward this ban was anything but swift. For nearly ten years, survivors and advocacy organizations worked to build political will and public awareness around the issue. Previous legislative attempts faced obstacles, with opponents raising concerns about parental rights and religious freedom. The eventual passage of AB 1267 signals a significant shift in how lawmakers and the public view the practice of child marriage within the United States.
With California now on board, 18 states have enacted laws prohibiting marriage before the age of 18 without any exceptions. However, child marriage remains legal in some form across 32 other states, though many have imposed varying restrictions such as minimum age requirements of 16 or 17, or allowances for judicial approval. This patchwork of laws means that a minor's ability to marry depends largely on which state they reside in—a reality that activists describe as unacceptable.
The global dimension of child marriage adds further urgency to the domestic debate. Worldwide, child marriage remains a widespread practice, affecting millions of girls each year. According to international organizations focused on the issue, child marriage is most prevalent in regions where poverty, lack of education, and gender inequality intersect. In many countries, girls are married off before their 18th birthday, often to older men, cutting short their childhoods and limiting their educational and economic opportunities.
Advocates in the United States have long pointed to the global fight against child marriage as context for their domestic efforts. While the scale of the problem is far greater in certain parts of the world, they argue that the United States cannot credibly advocate for change abroad while permitting the practice within its own borders. California's new law is being framed as a step toward aligning American domestic policy with the international consensus that marriage before 18 should be prohibited.
The question of whether bans prove effective is more complicated than it might first appear. While legal prohibitions send a clear message about societal values and provide tools for intervention, enforcement and cultural change often lag behind legislative action. In states that have already banned child marriage, researchers and advocates continue to monitor whether the laws are being properly enforced and whether they adequately protect minors from coercion.
Experts who study child marriage note that legal bans alone cannot address the root causes that drive the practice. Poverty, lack of educational opportunities, family pressure, and cultural traditions all contribute to child marriage in various communities. Effective prevention efforts, they argue, must combine legal reform with education, economic support for families, and resources for survivors seeking to escape marriages or recover from the consequences of early marriage.
For survivors who campaigned for the California law, the signing represents both a hard-won victory and a call to continue the fight in other states. With 32 states still permitting some form of child marriage, advocacy groups have signaled that their efforts will not stop at California's borders. The momentum generated by years of grassroots organizing may now translate into renewed pushes for similar legislation across the country.
California's ban also carries symbolic weight on the international stage. As one of the most populous and influential states in the United States, its decision to prohibit child marriage without exceptions adds pressure to holdouts elsewhere. Advocates hope that California's move will encourage other states to examine their own laws and consider whether exceptions allowing minors to wed—even in limited circumstances—are defensible in light of the evidence about the harms of child marriage.
Looking ahead, the effectiveness of California's law will depend on multiple factors: how it is implemented by state agencies, whether it is understood by families and communities, and whether resources are provided to support those affected by the change. The law removes legal sanction from child marriage, but changing deeply embedded social norms requires sustained effort over time.
The passage of AB 1267 marks a turning point for California, but the broader battle against child marriage—both in the United States and globally—remains unfinished. Survivors and advocates who spent nearly a decade pushing for this moment now face the challenge of ensuring that legal victories translate into real protection for vulnerable children. The California law is a milestone, but it is also a reminder of how much work remains. The other 32 states, and the international community, are watching closely.
