Florida Attorney General Sues TikTok in First Major Test of State's Child Social Media Law

Florida Attorney General James Uthmeier has filed a lawsuit against TikTok, accusing the social media platform of illegally allowing minors to use the app in defiance of a state law designed to keep younger children off social media. The civil complaint, filed in St. Lucie County Circuit Court, marks the state's first major enforcement action under House Bill 3, the law that restricts how social media companies handle accounts for Floridians under the age of 16.

The lawsuit asks the court to declare TikTok a public nuisance and seeks injunctive relief, civil penalties, and other remedies. It accuses the company of misleading parents about the nature of content available on the platform and of employing addictive design features that the state says are engineered to hook children. The action escalates a long-running standoff between Florida and the major social media companies over the state's effort to regulate minors' access to their products.

What the lawsuit alleges

According to the complaint, TikTok has failed to comply with provisions of HB 3 that require 14- and 15-year-olds to obtain a parent's consent before creating accounts and that prohibit children under 14 from holding accounts at all. The state alleges the company has not implemented adequate controls to keep underage users off the platform and has continued to allow minors to sign up and engage with content.

Beyond the age-verification claims, the lawsuit contends that TikTok's business model is built to exploit addictive behaviors, particularly among young users. The attorney general's office has argued publicly that the platform's design, including its algorithmically driven feed and engagement features, is intended to maximize the time children spend on the app. The complaint also invokes the Florida Deceptive and Unfair Trade Practices Act, alleging that the company misled parents about what their children would encounter on the platform.

The law behind the case

HB 3 took effect on January 1, 2025, and represents one of the most aggressive state-level attempts in the country to limit minors' use of social media. The law bars children under 14 from creating accounts on covered platforms and requires parental consent for 14- and 15-year-olds. It also directs companies to terminate accounts belonging to underage users and to honor requests from parents to delete their children's accounts.

The statute was a priority for state leaders who argued that social media poses documented risks to the mental health and well-being of young people. Supporters pointed to concerns about anxiety, depression, sleep disruption, and exposure to harmful content. Critics, including technology industry groups and some free-speech advocates, warned that the law raised constitutional questions and practical challenges around age verification, and litigation over the statute has accompanied it since before it took effect.

Why St. Lucie County

The decision to file in St. Lucie County Circuit Court places the case in a state trial court rather than federal court, keeping the dispute centered on Florida law and the state's consumer protection statutes. The public nuisance framing is significant: by asking a court to declare the platform a public nuisance, the state is invoking a legal theory that has been used in other high-profile litigation against industries accused of causing widespread public harm.

The venue and the legal theory together signal that Florida intends to press the case on state-law grounds, where it has the home-field advantage of its own statutes and courts. The choice also reflects the structure of HB 3, which gives the attorney general enforcement authority and the ability to seek civil penalties for violations.

TikTok's broader legal landscape

TikTok has faced legal and regulatory pressure on multiple fronts in recent years, from national security debates over its ownership to lawsuits in numerous states alleging harm to minors. The company has generally defended its safety features and parental controls, and it has contested claims that its platform is uniquely harmful or that its design is intended to addict users. The Florida case adds a state-specific enforcement dimension grounded in a statute written explicitly to govern minors' access.

The litigation also unfolds against the backdrop of separate constitutional challenges to HB 3 brought by industry groups, which have argued that the law infringes on protected speech and is preempted by federal law. The outcome of those challenges could shape the legal terrain on which the attorney general's enforcement action proceeds.

What it means for Florida families

For Florida parents, the lawsuit is a test of whether HB 3 can be enforced in practice. The law promised parents new authority over their children's social media use, but its real-world effect depends on whether companies comply and whether the state can compel compliance through the courts. A favorable ruling for the state could pressure TikTok and other platforms to tighten age verification and account controls for Florida users; an adverse ruling could expose the limits of the statute.

For young users, the immediate practical impact is uncertain. Age-verification systems remain technically difficult, and minors have long found ways around platform age gates. The case may ultimately turn as much on what compliance is feasible as on what the law requires, making it a closely watched bellwether for similar laws in other states.

What's next

The case now enters the litigation process, where TikTok is expected to respond to the complaint and may challenge the state's legal theories, including the public nuisance claim and the application of HB 3. The proceedings could stretch over months or longer, and the outcome may hinge on how the court interprets the company's obligations under the law and the evidence the state presents regarding underage users and the platform's design.

As the first significant enforcement action under HB 3, the lawsuit will be watched well beyond Florida's borders. Other states considering or implementing similar restrictions on minors' social media use will be looking to see whether Florida can translate its statute into enforceable obligations, and whether the courts will sustain the aggressive legal strategy the attorney general has chosen.
