New York State recently made a landmark decision to repeal a 1907 law that had long criminalized infidelity. Signed by Governor Kathy Hochul, this move eliminates a statute considered both outdated and unenforceable. Under the law, infidelity was classified as a misdemeanor, punishable by up to three months in jail. It required proof that one of the individuals involved was married, making such cases difficult to prosecute and raising questions about its relevance in modern society.
The origins of this legislation can be traced back to an era when divorce laws were highly restrictive, and evidence of unfaithfulness was often the only legal ground for separation. This law, among others, was intended to reinforce traditional marital ideals by discouraging extramarital relationships. It reflected a societal framework where personal behavior was closely regulated under the guise of maintaining public morality. However, as times changed, such statutes increasingly came to be viewed as relics of an era that no longer aligned with contemporary values.
Assemblymember Charles Lavine, the primary advocate for the law’s repeal, highlighted its declining application. Since the 1970s, fewer than a dozen cases had been prosecuted under this law, with only five resulting in convictions. The statute’s limited enforcement underscored its impracticality in today’s legal and cultural environment. For instance, one of the law’s last significant applications occurred in 2010, involving an individual accused of misconduct in public. Ultimately, the case did not proceed under infidelity charges, demonstrating the difficulties associated with enforcing this law.

Governor Hochul expressed the importance of modernizing laws to reflect societal progress, describing the infidelity statute as outdated and unnecessary. She emphasized that private matters like relationships should not fall under the purview of criminal law. “These are personal decisions best left to individuals, not courts,” she stated when signing the repeal into effect. The move reflects an acknowledgment that laws rooted in moral judgment should not dictate personal choices in a contemporary legal system.
This repeal also aligns with broader trends in the United States, where many states have begun reassessing and overturning similar laws. Although statutes criminalizing infidelity remain on the books in certain regions, their enforcement has been minimal for decades. Critics argue that such laws have little impact on promoting public morality but instead serve as tools for shaming individuals or complicating divorce proceedings. By repealing its law, New York has positioned itself at the forefront of this movement toward modernization.
Efforts to repeal New York’s infidelity law began as early as the 1960s. At that time, a state commission reviewing the penal code found the law nearly impossible to enforce. While there was initial legislative support to remove the statute, opposition arose from those concerned about potential societal repercussions. Some lawmakers feared that repealing the law could be perceived as condoning extramarital relationships, leading to hesitation and stagnation in legislative efforts.
Over time, changing cultural attitudes and a growing recognition of the law’s shortcomings renewed calls for its repeal. Advocates emphasized that the statute neither protected communities nor served any meaningful purpose. Assemblymember Lavine pointed out that the law’s existence could even harm individuals by exposing them to public ridicule or being used as a weapon in legal disputes. These arguments eventually gained traction, culminating in the successful repeal of the statute in 2023.
The decision to strike this law from the books carries significant symbolic weight. It underscores the importance of personal autonomy and the evolving understanding of relationships in modern society. By removing legal penalties for what is ultimately a personal matter, New York affirms the idea that private decisions should not be subjected to outdated moral codes.

Critics of such laws have long argued that they often disproportionately affect marginalized groups, including women, and perpetuate unfair societal judgments. The repeal removes the potential for misuse in legal proceedings and emphasizes fairness in matters of family law. It also reflects an understanding that relationships are complex and deeply personal, making them ill-suited for criminal regulation.
The repeal of New York’s infidelity law highlights the importance of updating legislation to align with contemporary values and practical realities. While the statute once symbolized a commitment to traditional marital ideals, its removal acknowledges the evolving definitions of relationships and personal freedom. This move is not only a step forward for New York but also sets an example for other states to reevaluate similar laws still in place.
As debates about privacy, personal freedom, and the role of government in regulating relationships continue, New York’s decision serves as a reminder of the need for progressive and relevant legislation. This repeal represents a shift away from laws rooted in moralistic judgments toward a framework that respects individuality and fairness, paving the way for a more equitable legal landscape.
