California has banned child marriage outright, with no exceptions. Assembly Bill 1267, signed by Governor Gavin Newsom on September 30, prohibits minors from being issued a marriage license or establishing a domestic partnership. The law replaces a regime that allowed children of any age to marry with parental consent and a judicial order. The numbers are stark. Unchained at Last, the advocacy group that pushed the legislation, estimates 9,000 children are married in California every year. That figure sat undisturbed for years while the state's legal framework treated a court order and parental permission as adequate safeguards for a decision that reshapes a minor's legal identity, financial autonomy, and access to protections like domestic violence shelters. California becomes the 18th state to enact a full ban. The remaining 32 states still permit some form of child marriage, typically through parental consent, judicial approval, or both. The patchwork means a minor's legal protection depends entirely on geography — a structural failure that activists are working state by state to close. Activist Courtney Stodden, who married 51-year-old actor Doug Hutchison at age 16 in 2011, appeared alongside Newsom at the signing. Stodden has publicly described the marriage as a source of deep regret and called the bill a victory for survivors. "I will keep fighting until children are protected from marriage in all 50 states," she said. The prior legal framework was a textbook example of how institutional inertia protects harmful defaults. Parental consent as a gatekeeping mechanism fails precisely when the parents are the ones arranging the marriage. Judicial review, while sounding rigorous, operated as a rubber stamp — courts had no standard for evaluating whether a child's interests were being served, and minors lacked independent legal counsel in such proceedings. The new law contains no exceptions — no religious carve-outs, no pregnancy exceptions, no judicial override. This is notable because previous legislative attempts in other states have been weakened or killed by exception clauses that effectively preserved the practice while appearing to restrict it. The trajectory is clear but slow. Eighteen states down, 32 to go. The federal government has no minimum marriage age, leaving this entirely to state legislatures. Each ban requires its own campaign, its own coalition, and its own fight against lobbies ranging from religious groups to libertarian objectors who frame parental consent as a rights issue rather than a safeguarding failure.
